Cancellation suppression is an explicit manager policy; do not accidentally convert unrelated `BaseException` failures into recoverable connection errors. +- Server cleanup must clear session and transport-visible state even when exit-stack cleanup raises, so the same server object can reconnect without exposing stale session handles or workers. + +## Manager State + +- Keep configured servers, connected servers, failed servers, active servers, and per-server errors as distinct views. `active_servers` is the agent-facing list; with `drop_failed_servers=True` it excludes failed connections while preserving configured order. +- Non-strict connection records failures and continues with the connected subset.

The same lock must cover tool calls, tool listing, prompts, and resource operations that share that session; serializing only `call_tool()` still permits sibling cancellation and protocol races. +- Preserve outer cancellation. A cancelled shared request may qualify for an isolated-session retry only when the transport identifies it as an inner or transient session failure and retry budget remains. +- Isolated-session retries are transport-specific recovery.

Validate required arguments locally before starting retries so deterministic input errors never reach the server or consume retry budget. +- MCP tool failure conversion follows the effective server or agent `failure_error_function`. Explicit `None` means propagate; cancellation of the parent run must not become model-visible tool failure output. + +## Tool Discovery, Cache, and Filtering + +- The unfiltered server tool list is the cacheable value. Apply static or dynamic filters to a copy for each requesting agent and run context; never let one request's filtered or merged metadata mutate the shared cache. +- `cache_tools_list=True` assumes server schemas are stable until `invalidate_tools_cache()` marks them dirty. Connection or filter changes must not accidentally make a stale filtered list authoritative. +- Dynamic filters require both `run_context` and agent. A filter exception excludes that tool and logs the failure rather than exposing it by default. +- Schema conversion to strict form is best effort and must not mutate the MCP server's original input schema.

Exceptions that escape the background guardrail task must become a `RealtimeError` event rather than disappearing. +- Realtime function-tool input guardrails follow the same optional pre-approval and mandatory post-approval ordering as standard function tools, but their rejection is returned through Realtime tool output and events. +- Follow-up `response.create` work triggered by tools, handoffs, or guardrails must respect the active response lifecycle. Wait for `response.done` or the model layer's equivalent gate before starting a conflicting response. + +## Failure-Path Tests + +Add focused tests for affected phases: + +1. Instruction, tool, or handoff resolution fails during entry. +2. Model connection fails after listener registration. +3. A background tool or guardrail task raises or is cancelled. +4. Cleanup runs while event iterators are waiting. +5. `close()` is called repeatedly or from another task. +6. A handoff or `update_agent()` fails partway through model-settings application. +7. Tool output sending fails after local execution and must be retried without running the tool twice. +8.

Keep discovery, approval partitioning, and invocation as separate phases. + +- Fresh and resumed turns need different plans. A resumed interruption must execute unresolved or newly approved work without rediscovering or rerunning completed calls. +- Approval state is authoritative once resolved. Do not call a dynamic `needs_approval` checker again for a call whose status is already approved or rejected. +- Deduplicate by invocation identity before execution while preserving model order for public call and output items. A repeated tool definition is not a repeated call, and a repeated call ID must not execute twice. +- Validate enabled tools and canonical lookup before side effects. A tool disabled after model output or absent from the resolved tool set must follow the configured missing-tool behavior rather than reaching a stale callable. + +## Approval and Guardrail Ordering + +- Pre-approval input guardrails are an early rejection optimization. They may run before an approval interruption, but input guardrails must run again immediately before invocation because state, policy, or arguments may have changed while approval was pending. +- Rechecking guardrails does not mean rechecking approval. Persisted approval decisions and rejection messages must remain attached to the same tool identity and call ID across `RunState` resume. +- Tool input guardrails finish before the local side effect. Tool output guardrails finish before output becomes accepted run state, model input, or persisted session history. +- The tool guardrail pipeline applies to `FunctionTool` invocation. Handoffs, hosted tools, built-in provider tools, and nested `Agent.as_tool()` runs have separate execution boundaries unless they explicitly opt into equivalent checks. + +## Concurrency and Failure Semantics + +SDK-side function-tool concurrency is independent of provider-side parallel tool-call generation. The provider controls how many calls appear in one response; `RunConfig.tool_execution.max_function_tool_concurrency` controls how many local function handlers run at once. + +- Preserve model order in emitted outputs even when handlers complete out of order. +- Isolate sibling results. A cancelled or failed call must not discard outputs already produced by successful siblings. +- Distinguish cancellation of one tool handler from cancellation of the parent run. Tool-local cancellation can follow the configured tool failure policy; parent cancellation must propagate promptly instead of becoming model-visible tool output. +- `task.cancel()` is not terminal cleanup. On sibling failure, drain cancelled handlers and wait for post-invocation work within the bounded cleanup policy. On parent cancellation, cancel remaining tasks and attach result callbacks so late exceptions are observed without delaying cancellation indefinitely. +- Select and raise failures deterministically when several tasks fail, while still observing secondary failures. Do not let task-set iteration order or eager task execution change the public result. + +## Invocation Boundary + +- Decorated synchronous Python functions run through `asyncio.to_thread()` so they do not block the event loop. Async function tools run in the event loop and are the only decorated handlers that support SDK timeouts. +- Timeout handling and ordinary exception handling are distinct policies. `timeout_behavior` and `timeout_error_function` own timeout conversion; `failure_error_function=None` means ordinary exceptions propagate instead of becoming model-visible output. +- Tool start/end hooks and function spans surround the actual invocation once per call, including failure and cancellation paths. Do not emit a successful end state before output guardrails complete. +- Per-run resources such as resolved `Computer` implementations must be initialized and disposed by the run that acquired them. +- Nested `Agent.as_tool()` execution owns a nested run loop and nested resumable state. Scope cached nested state by the parent `RunState` and call identity, not only by the reusable agent or tool object. +- `AgentToolUseTracker` records tool use per agent identity. When `reset_tool_choice=True`, reset the effective next-turn tool choice after that agent uses a tool so `required` or a named choice cannot force an accidental loop; do not mutate the agent's declared settings across independent runs. +- Persist and restore the tool-use tracker across interruption and sandbox resume, including graphs with duplicate agent names, so resumed tool-choice behavior matches uninterrupted execution. + +## Review Checklist + +1.

Distinguish the reported symptom from the reporter's proposed cause or fix. +- Identify the released behavior boundary when compatibility or regression claims matter. +- Verify whether linked evidence matches the PR's exact runtime variant, provider or tool type, triggering condition, and user outcome. A generic issue title, conceptual similarity, or wording such as `Related to` does not transfer evidence of need to an adjacent extension. If the reported scenario has already been fixed, treat additional variants as new needs requiring their own evidence. + +Respect repository instructions for remote access and mutation. A review does not authorize comments, labels, branch changes, pushes, or other remote writes. + +### 2. Establish the unmet need and challenge the proposed solution + +Complete this pass before deeply evaluating a proposed implementation and before any positive issue or PR assessment. + +First assign one `Need evidence` status: + +- **Demonstrated**: The exact scope has a concrete supported scenario, a real-path reproduction, a released compatibility requirement, repeated demand, or a broad invariant with a meaningful consequence. +- **Plausible but unproven**: The path can exist, but realistic provider behavior, user reach, frequency, consequence, or demand is not established. +- **Already covered**: A reasonable supported workflow already satisfies the outcome. +- **Unsupported**: The outcome belongs outside the SDK contract or at a provider, adapter, or caller-owned layer. + +Only `Demonstrated` need may receive `Merge-worthy as-is` or `Merge-worthy after focused changes`. For `Plausible but unproven`, prefer `Needs evidence` or `Not worth completing`; for `Already covered` or `Unsupported`, prefer closure or the relevant simpler alternative. + +1. Restate the desired user outcome without naming the requested API, class, file, option, or implementation. Separate the actual constraint from the reporter's preferred mechanism. +2. Trace the closest supported ways to achieve that outcome in the current release and current target. Inspect the owning code path, public API, tests, and relevant docs rather than assuming that an unfamiliar capability is missing. Consider configuration, composition, cloning, callbacks, extension points, provider adapters, and doing the work at a caller-owned layer. +3. Determine whether the report shows a capability gap, an ergonomics or discoverability problem, an unsupported use case, or no demonstrated problem. A more convenient spelling is not automatically a missing capability. +4. Compare the proposed solution against the strongest existing approach and at least one better-design candidate: no code change, clearer documentation or validation, a narrower fix, reuse of an existing abstraction, or enforcement at a more coherent shared boundary. +5. For each viable approach, compare whether it satisfies the concrete scenario, what new public or internal contract it creates, cross-path consistency, compatibility, and permanent maintenance cost. + +Do not treat a test proving that new code can work as evidence that the feature is needed. A `FakeModel` response, manually constructed provider item, mock, or new regression test can establish code-path reachability and implementation correctness; it does not by itself establish realistic provider behavior, user reach, frequency, practical consequence, or demand. + +API symmetry, naming consistency, and parity with an adjacent tool, provider, or output type are design arguments, not evidence of need. Parity may justify work when it removes existing complexity or enforces a broad demonstrated invariant, but adding branches, tests, documentation, or public behavior requires independent practical justification. + +If the need is not `Demonstrated`, inspect the patch only far enough to understand its contract, risk, and maintenance cost. Do not turn implementation defects, missing tests, or documentation gaps into a request-changes recommendation, because those questions become merge-blocking only after the need gate passes. If the report provides no concrete scenario, the existing functionality appears sufficient, or the requested mechanism solves only a hypothetical convenience problem, prefer `Needs evidence`, `Close`, `Supersede with a simpler alternative`, or `Not worth completing` over designing the requested feature on the reporter's behalf. + +### 3. Discover competing open PRs proportionally + +Do this before deeply evaluating a specified PR. A PR URL selects the starting point, not necessarily the entire comparison set. + +- Determine the primary issue from explicit closing keywords, linked issues, issue timeline or development links, PR body and comments, and the reproduced symptom. If the association is inferred rather than explicit, state the evidence. +- When an issue is explicitly linked, enumerate all open PRs that address it through the issue timeline, development links, cross-references, closing keywords, and ordinary references. Include draft PRs but label them as drafts. +- When no issue is linked, run a bounded duplicate search using the strongest two or three signals from the title, reproduction, violated invariant, and runtime path. Stop when additional queries are unlikely to produce a credible competing implementation. +- Exclude closed or merged PRs from the active comparison set, while using them as history when relevant. +- Do not group PRs merely because they mention the same subsystem. Require a shared issue, symptom, violated invariant, or materially overlapping fix. +- Record the search methods and candidate set internally. If repository access cannot establish completeness, say so instead of claiming that every open PR was found. Do not list unrelated search hits in the final report. + +When multiple candidates exist, compare them on need coverage, runtime correctness, scope, implementation layer, tests, compatibility, complexity, readiness, remaining maintainer work, and whether useful parts can be combined. Prefer the best maintainable solution, not the first submission or the smallest diff by default. + +### 4. Use a two-stage evidence flow + +Always begin with a desk review. Inspect the concrete runtime path before judging a small change as either trivial or meaningful. Check callers, adjacent helpers, validation layers, fallback paths, and existing tests. Search history or documentation only when it changes the decision. Inspecting test code is part of the desk review; executing tests, imports, examples, reproductions, benchmarks, or service calls is a runtime probe. + +For repository-specific runtime invariants, start with `.agents/references/README.md` and open only the references that match the affected boundary. Treat `.agents/references/` as read-only during issue and PR review: use it to identify expected invariants, adjacent surfaces, and regression risks, then verify the current claim against the remote change, current code, tests, docs, release boundary, and focused runtime evidence. Do not edit references as a side effect of the review, infer current issue or PR status from them, or treat old issue or PR outcomes as current evidence. If the review reveals a reusable invariant that should be captured, recommend a separate repository-maintenance update unless the user explicitly asks to update references in the same task. + +Use this evidence order across the two stages: + +1. Trace the closest existing supported capabilities and determine whether they already satisfy the underlying user outcome. +2. Inspect existing tests and complete the code-path trace, including the mandatory interleaving and ownership pass when triggered, without executing code. +3. With explicit user approval, run a focused local reproduction of the exact claim when the desk-review rules below require it. +4. A comparison with the released version, base branch, or known-good control. +5. A broader runtime matrix only when the maintainer decision remains uncertain and the user approves it. + +#### Stage 1: desk review + +Produce an initial result from static evidence before running code: + +##### Mandatory unmet-need and design pass + +Before a positive assessment, complete the pass in step 2 and be able to state all of the following from concrete evidence: + +1. The user outcome that current supported behavior cannot achieve. +2. The closest existing API or composition path and the exact reason it is insufficient. +3. Why the proposed behavior belongs at the chosen abstraction layer instead of a caller, adapter, validation, documentation, or existing extension point. +4. Why the proposed permanent contract is better than no code change and the strongest narrower alternative. +5. What real scenario, compatibility requirement, or repeated demand justifies the new maintenance surface. +6. Whether maintainers would choose to pursue the same work if no contributor had already supplied a patch. + +If any answer is missing and could change whether code should exist at all, do not call the issue actionable or the PR merge-worthy. Request only the evidence needed to distinguish a genuine capability gap from a usage, discoverability, or solution-design problem. This is a product and architecture evidence gap, not a runtime-probe trigger by itself. + +##### Mandatory interleaving and ownership pass + +Run this pass before any positive PR assessment when a patch adds, removes, or reorders cleanup, retry, reconnect, cancellation, listeners, shared futures or tasks, connections or streams, state flags, or mutable state across an `await`, callback, event, or deferred completion. + +1. Name each shared resource or state value and the operation that owns it. Include listeners, futures, tasks, connections, streams, locks, caches, state flags, persistence, and telemetry. +2. Trace at least two overlapping operations, `A` and `B`, across every suspension or re-entry point. Check `A pending -> B starts -> A fails -> B succeeds`, `A pending -> B starts -> B fails -> A succeeds`, close or cancellation between setup and completion, and a stale completion arriving after newer work. +3. For every cleanup or rollback, identify the exact attempt and resource generation it is allowed to dispose. Treat unconditional cleanup after a suspension point as a regression candidate until the code proves it cannot tear down newer or surviving work. +4. Compare base and head for the survivor invariant. Replacing duplicated work with missing handlers, a closed shared resource, reverted state, or a failed surviving task is a regression, not successful cleanup. +5. Inspect tests for controlled interleavings using deferred futures, callbacks, or events. Require assertions about the surviving operation's observable behavior and final resource state, not only listener counts or individual exception results. + +Do not mark a concurrency-sensitive patch `Merge-worthy as-is` merely because sequential reconnect, retry, failure, and close tests pass. If the code trace proves an unsafe interleaving, conclude from static evidence and request a focused fix and regression test. If ownership remains ambiguous, keep the result preliminary and request approval for the smallest decisive runtime probe. + +- If the claim or PR is decisively negative from a complete reachable code-path trace, conclude the review without a runtime probe. Examples include an impossible or unsupported path, duplicated existing handling, a demonstrated no-op, a direct compatibility break, or a clearly wrong abstraction. Do not call an ambiguous result negative merely to avoid a probe. +- If the initial result is positive and there is no unresolved runtime concern, and any triggered interleaving and ownership pass is complete, the desk review may be sufficient for a final maintainer decision. Do not run a probe only to restate evidence that cannot plausibly change the decision. +- If the initial result is positive but there is any unresolved runtime concern that could plausibly change claim validity, severity, merge-worthiness, required changes, or the preferred competing PR, stop before executing code. Report a `Preliminary assessment`, name the concern, propose the smallest decisive probe and control, and ask the user for approval to run it. +- A purely stylistic, documentation, CI-status, or repository-readiness concern does not trigger a runtime probe unless it masks a runtime question. + +Do not issue a definitive positive maintainer decision while a decision-relevant runtime concern remains unresolved. If the user declines the probe, keep the result preliminary and state the exact confidence limitation. + +#### Stage 2: approved runtime probe + +After explicit approval, run only the smallest probe needed to resolve the stated concern. Exercise the real public or internal path and include a base, release, or known-good control when relevant. Do not stop at a happy-path smoke check when failure behavior determines the decision. Return to the user for separate approval before expanding materially beyond the approved probe. + +For latency, timeout, buffering, backpressure, or cleanup claims, measure at least one observable elapsed-time or state-transition path when feasible. Do not assume that a mocked unit test exercises real scheduling or provider behavior. Prefer a local probe first; use an approval-gated live-service probe only when local evidence cannot settle the decision. + +Use `$runtime-behavior-probe` only when the user explicitly invokes it and the skill is available, or when the user explicitly approves using it for the proposed runtime work. Preserve its environment-variable approval, live-service, cost, cleanup, and reporting gates. Do not make ordinary maintainer review depend on that skill being available. + +For changes involving validation, fail-fast behavior, cleanup, retries, interruption, or concurrency, trace lifecycle ordering in addition to the main behavior: + +- Identify listeners, tasks, connections, files, locks, state mutations, and other resources acquired before the new check or failure point. +- Verify cleanup when construction, context-manager entry, validation, connection, or execution raises before normal teardown runs. +- Require a negative-path test when a failure can leave observable state or resources behind. + +Do not over-investigate. Stop when additional evidence is unlikely to change validity, severity, or the maintainer recommendation. + +### 5. Calibrate validity and impact + +Use `references/evaluation-framework.md` to assess claim validity, realistic reach, consequence, breadth, frequency, recoverability, compatibility, and severity. Keep observed facts separate from inference and state any missing evidence that could change the decision. + +Report the `Need evidence` status before classifying the need as a capability gap, ergonomics or discoverability gap, unsupported use case, or no demonstrated gap. Do not assign practical impact to the absence of the requested mechanism when an existing supported workflow already produces the requested outcome. Do not infer practical importance merely from reachability, API asymmetry, or a technically successful patch. + +For a PR, make `Severity` describe the underlying issue or user need only. Do not combine it with the risk created by the proposed patch. Report a meaningful patch-induced regression, compatibility, lifecycle, or maintenance risk separately as `Patch risk`. + +Do not infer that a report is low-value merely because an AI may have found or written it. Do not speculate about authorship or motive. Identify contribution-shaped reports through objective signals: no reproducible behavior, unrealistic inputs, an impossible call path, duplicated existing handling, tests that do not exercise the claim, or a fix whose runtime result is a no-op. + +### 6. Apply the maintainer-effort test + +Use the framework's issue dispositions and PR checks to decide whether the outcome justifies permanent code, tests, documentation, and maintainer attention. Classify code quality separately from repository readiness. + +Use one code recommendation: + +- **Merge-worthy as-is**: real need, sound implementation, proportionate scope, adequate tests. +- **Merge-worthy after focused changes**: real need and viable direction, with bounded corrections. +- **Supersede with a simpler alternative**: real need, but a smaller or more coherent fix is preferable. +- **Not worth completing**: negligible or unsupported impact, no-op behavior, wrong abstraction, or excessive completion cost. + +`Merge-worthy as-is` and `Merge-worthy after focused changes` are invalid unless `Need evidence` is `Demonstrated`. A bounded set of implementation fixes cannot promote a `Plausible but unproven` need into a merge-worthy recommendation. + +For `Merge-worthy as-is` and `Merge-worthy after focused changes`, use one repository-readiness status when it helps communicate the integration state: + +- **Ready**: current head is reviewable and required checks are green. +- **CI or review pending**: code recommendation is stable, but required external gates are incomplete. +- **Rebase or conflict resolution required**: the head cannot merge cleanly or is materially stale. +- **Blocked**: a concrete external or repository condition prevents a reliable merge decision. + +Omit repository readiness for `Supersede with a simpler alternative` and `Not worth completing`; CI, review, mergeability, or branch freshness does not change those dispositions. Put any validation limitation that materially affects confidence in the evidence instead. When readiness is included, use exactly one of the four statuses above and do not invent variants such as `ready mechanically` or use rebase status for semantic staleness. + +Do not downgrade an otherwise sound code recommendation solely because CI is pending. Do not call a PR ready when semantic conflict resolution or material code changes remain. + +When multiple open PRs address the same issue, make one portfolio-level recommendation: select the strongest PR, request focused changes in one candidate, combine specific ideas into one PR, supersede all candidates with a simpler approach, or close duplicates. Explain why the recommended path is better than each alternative without turning the report into line-by-line review. + +Always compare the proposed patch with the strongest existing supported approach and at least one alternative: no code change, validation or documentation, a narrower fix, reuse of an existing helper, or a different layer that enforces the invariant consistently. A review is incomplete if it establishes only that the patch works without establishing why the current product cannot meet the underlying need and why this design is preferable. + +When multiple plausible semantic scopes, compatibility boundaries, or public API contracts remain, do not ask the contributor to choose among maintainer-owned options. Decide the preferred scope from the evidence, compatibility contract, and product/API design principles, then request that specific change. If the evidence is insufficient to choose, mark the review preliminary or request maintainer input; do not present an open-ended implementation fork as the contributor's decision. + +### 7. Report findings and maintainer action + +Choose the assessment language using this precedence: + +1. Follow an explicit language request in the current conversation. +2. Follow an applicable language instruction from `~/.codex/AGENTS.md`, the repository's `AGENTS.md`, or another governing instruction file. +3. If recent conversation turns are consistently in one language, use that language. +4. Otherwise, default to English. + +Do not infer the assessment language from the GitHub URL, contributor, code, or browser locale. Maintainer comment drafts remain English regardless of the assessment language. Keep the report decision-oriented and compact. Use no more than five evidence bullets by default; add more only when the decision genuinely depends on them. + +Use the matching compact report variant in `references/evaluation-framework.md`. While runtime approval is pending, use its preliminary-assessment variant and end with the approval request instead of presenting a final recommendation. Collapse sections for simple cases rather than padding the answer. Put unexpected or negative runtime findings first, and name the preferred PR or approach explicitly when candidates compete. + +For PRs, put `Need evidence` before code recommendation. When the need is not `Demonstrated`, lead with that result, omit repository readiness, and avoid presenting patch fixes as the primary maintainer action. + +When existing functionality or a better alternative materially affects the decision, state it explicitly in the evidence and recommendation. Name the exact supported path, what it does and does not cover, and why it is preferable. Do not bury a `Not worth completing` or `Supersede with a simpler alternative` conclusion beneath praise for implementation quality. + +When recommending closure, requesting more evidence, requesting code changes, or superseding a PR, append the English, copy-paste-ready maintainer comment defined by the framework. If multiple PRs need different actions, label one draft for each affected PR. Include only merge-blocking requests in the main action paragraph; keep optional documentation or polish clearly non-blocking or omit it. + +For request-changes comments, phrase maintainer-owned semantic decisions as a directive, not as a menu. It is fine to mention the rejected alternative briefly in the rationale, but the requested action must identify the chosen behavior, scope, or compatibility boundary. Use "please do X because..." instead of "either do X or Y" when X versus Y changes the SDK contract or user-visible semantics. + +Do not produce a line-by-line review unless requested. Do not equate passing tests with merge-worthiness, or a logically correct patch with practical value. + +## Resource + +- `references/evaluation-framework.md` contains the severity rubric, evidence checks, lifecycle review, issue dispositions, PR quality checks, maintainer-comment guidance, and report variants. diff --git a/.agents/skills/maintainer-review/agents/openai.yaml b/.agents/skills/maintainer-review/agents/openai.yaml new file mode 100644 index 0000000..549b0a9 --- /dev/null +++ b/.agents/skills/maintainer-review/agents/openai.yaml @@ -0,0 +1,4 @@ +interface: + display_name: "Maintainer Review" + short_description: "Gate PR value on demonstrated user need" + default_prompt: "Use $maintainer-review with this GitHub issue or PR URL.

Merge only when the fix is small and clearly improves an invariant. +- **Moderate**: Plausible supported use fails or produces incorrect behavior for a meaningful subset of users. Prioritize a bounded fix and regression test. +- **High**: Common or important supported use is broken, causes serious compatibility problems, leaks sensitive data, or risks persistent corruption. Treat as urgent and require strong validation. +- **Critical**: Broadly exploitable security impact, severe data loss, or systemic failure requiring immediate coordinated action.

Code may be warranted. +- **Ergonomics or discoverability gap**: the outcome is already possible, but the supported route is confusing or unnecessarily difficult. Prefer documentation, validation, or a narrowly justified convenience improvement. +- **Unsupported use case**: the desired outcome lies outside the SDK contract or belongs at a provider, adapter, application, or other caller-owned layer. Do not expand the core API merely to make it possible. +- **No demonstrated gap**: no concrete scenario proves that existing functionality is insufficient. Request evidence or close rather than designing from the proposed mechanism. + +Passing tests for a new implementation establish feasibility and correctness, not need. A `FakeModel` response, manually constructed provider item, mock, or synthetic fixture does not establish realistic provider behavior, user reach, frequency, consequence, or demand. API symmetry and parity with an adjacent runtime are design arguments, not need evidence. A technically coherent patch can still be `Not worth completing` when the motivating scenario is hypothetical, already supported, or better solved elsewhere. + +Use the counterfactual maintainer test: if the PR did not already exist, would maintainers choose to file and implement the same work from the available evidence? Contributor effort lowers implementation cost but does not create product need or remove permanent maintenance cost. + +When the need is not `Demonstrated`, inspect implementation only far enough to estimate contract, risk, and maintenance cost. Do not convert patch defects, missing tests, or documentation gaps into a request-changes disposition; those become merge blockers only after the need gate passes. + +## Issue disposition + +Choose one primary action: + +- **Prioritize**: confirmed moderate-or-higher impact or an important invariant with no safe workaround. +- **Accept, low priority**: confirmed low impact, existing supported functionality is insufficient for the demonstrated scenario, and a proportionate fix appears possible. +- **Narrow scope**: a valid core exists, but the report overstates affected paths or expected behavior. +- **Needs evidence**: plausible claim, but no minimal reproduction, supported setup, contract basis, or concrete scenario showing why existing functionality is insufficient. +- **Close**: duplicate, unsupported, unreachable, contradicted, no-op, already addressed by a reasonable supported path, or not worth permanent complexity. + +When requesting evidence, ask only for information that could change the disposition. + +## PR quality and value + +Assess these independently: + +1. **Need**: Same-scope issue or runtime evidence demonstrates a concrete unmet user outcome that the closest supported capability cannot reasonably satisfy. Do not inherit evidence from an adjacent variant or already-fixed scenario. +2. **Correctness**: The fix works for the reported case and meaningful boundaries. +3. **Placement**: The invariant is enforced once at the right layer instead of duplicating existing functionality, patching locally, or moving caller- or provider-owned policy into the core SDK. +4. **Consistency**: Equivalent sync/async, streaming/non-streaming, provider, serialization, and resume paths remain aligned where applicable. +5. **Tests**: A regression test fails on the base, passes on the head, and tests the exact non-happy-path value or state. When shared state crosses an asynchronous boundary, tests control relevant completion orders and assert the surviving operation's behavior and final resource state. +6. **Compatibility**: Released positional APIs, wire formats, persisted schemas, and established error behavior are preserved or intentionally migrated. +7. **Proportionality**: Complexity and public surface are justified by impact. +8. **Completion cost**: Remaining fixes, docs, tests, and design work are bounded enough to justify maintainer attention. + +A PR can be correct but not merge-worthy. Typical reasons include a nonexistent or negligible need, an outcome already supported through a reasonable existing mechanism, a no-op on the actual runtime path, incomplete cross-path semantics, an abstraction cost larger than the benefit, or a simpler design at another layer. + +Do not use implementation correctness, bounded remaining work, CI status, or contributor effort to upgrade a need that is only `Plausible but unproven`. Merge-worthiness is gated by demonstrated need, not by how close the patch is to completion. + +Keep issue impact and patch risk separate. `Severity` describes the underlying issue or user need. A regression, compatibility break, lifecycle leak, or maintenance hazard introduced by the proposed patch belongs under `Patch risk` and must not inflate or obscure the issue severity. + +When a PR exposes an ambiguous semantic boundary, decide whether that boundary belongs to maintainers before drafting requests. If the choice affects SDK contract, compatibility, persistence, error semantics, public API meaning, or cross-path behavior, the review should pick one direction or explicitly block on maintainer input. Do not delegate that choice to the contributor as "either X or Y"; ask for the chosen behavior and the tests or docs needed to lock it down. + +## Documentation threshold + +Do not treat documentation as automatically required for every public option, constructor parameter, provider setting, or behavior change. Make docs merge-blocking only when at least one of these is true: + +- Existing user-facing docs become materially false, unsafe, or misleading. +- Correct or safe use depends on a non-obvious constraint, migration step, compatibility boundary, or operational warning. +- Repository policy, the accepted issue scope, or an explicit maintainer decision requires documentation in the same PR. +- The intended feature would be practically unusable or undiscoverable by its target users without a documented entry point, and generated API reference or clear code-level discovery is insufficient. + +If docs would merely improve discoverability or completeness, keep them non-blocking. Do not change `Merge-worthy as-is` to `Merge-worthy after focused changes` solely for optional docs, and do not include optional docs in the maintainer comment's required-action paragraph. Respect an explicit maintainer choice to omit docs or defer them to a separate follow-up. + +## Lifecycle and failure-path review + +Apply this section when a change adds validation, fail-fast behavior, cleanup, retries, interruption, background work, or concurrency. + +- Identify the earliest point where all dynamic inputs needed for a correct decision are available. +- List side effects before and after that point: listeners, tasks, connections, files, locks, caches, state mutations, and telemetry. +- Exercise failure during construction, context-manager entry, validation, connection, and execution when those phases exist. +- Confirm that normal teardown is actually entered. If an enter or constructor fails, verify cleanup explicitly rather than assuming an exit hook runs. +- Prefer validation after dynamic configuration is resolved but before avoidable side effects begin. +- Require a regression test for any listener, task, connection, or state that could remain after failure. + +## Concurrency and cleanup ownership + +Apply this section before a positive assessment whenever lifecycle work crosses an `await`, callback, event, deferred completion, retry, reconnect, cancellation, or shared resource boundary. Sequential correctness is insufficient because a patch can improve isolated cleanup while introducing cross-attempt teardown. + +Use a two-operation interleaving matrix during desk review: + +| Ordering | Required question | +|---|---| +| `A pending -> B starts -> A fails -> B succeeds` | Can A's cleanup remove or revert anything B needs? | +| `A pending -> B starts -> B fails -> A succeeds` | Can B's cleanup leave A successful but non-functional? | +| `A succeeds -> B starts -> stale A completion` | Can stale A overwrite B's newer state or generation? | +| setup -> close/cancel -> late completion | Can late work resurrect listeners, state, tasks, or connections after teardown? | + +For each ordering: + +- Identify the resource owner before and after every suspension point. +- Distinguish per-attempt resources from shared runner, session, transport, cache, or listener state. +- Require cleanup to carry an ownership token, generation, identity check, serialization guarantee, or another invariant that prevents cross-attempt disposal. +- Compare base and head on the survivor invariant. Fewer duplicates do not justify losing the only active handler, connection, task, or state update. +- Require a controlled interleaving test when the ordering is reachable. The test must assert both the failing operation and the surviving operation's observable behavior after all completions settle. + +An unscoped `finally`, `except`, close handler, cancellation callback, or rollback that mutates shared state after a suspension point is merge-blocking when another operation can still own or use that state. + +## Better-alternative prompts + +Start with the strongest existing supported path, then test at least one additional alternative against the proposed patch. Do not complete a positive review without this comparison. + +- Can the requested outcome already be achieved through configuration, composition, cloning, callbacks, extension points, a custom provider or adapter, or caller-owned code? +- If the existing route is awkward, is the problem discoverability or ergonomics rather than missing capability? +- What happens if maintainers make no code change? +- Can input validation or an existing helper enforce the invariant earlier? +- Can the fix be limited to the one supported path that fails? +- Would documentation or a clearer error prevent misuse without runtime complexity? +- Can the test be added first to reveal the smallest correct change? +- Is the proposed public option compensating for an internal design issue? +- Is the proposed core behavior actually provider- or application-specific policy that belongs at another layer? + +## Competing PR comparison + +When two or more open PRs address the same issue, first verify that they belong in one comparison set. Accept an explicit issue link, the same minimal reproduction, the same violated invariant, or materially overlapping runtime paths as association evidence. Do not treat a shared label or subsystem as sufficient. + +Compare each candidate on the same evidence basis: + +| Criterion | Question | +|---|---| +| Need | Does a concrete user outcome remain unmet after tracing existing supported functionality? | +| Existing capability | Could every candidate be avoided by configuration, composition, an extension point, or a better caller- or provider-owned solution? | +| Coverage | Does it solve the whole confirmed issue, a useful subset, or an adjacent problem? | +| Correctness | Does the fix work on the real path and meaningful boundaries? | +| Placement | Does it enforce the invariant at the correct shared layer? | +| Tests | Does it reproduce the base failure and distinguish the candidate approaches? | +| Compatibility | Does it preserve released APIs, state, protocol, providers, and established behavior? | +| Complexity | What permanent branches, abstractions, configuration, or coupling does it add? | +| Readiness | Is it mergeable now, or how much focused work remains? | +| Reuse | Are there valuable tests or implementation pieces that should be combined into another candidate? | + +Choose one portfolio-level disposition: + +- **Prefer one PR**: identify the strongest candidate and close or supersede duplicates. +- **Prefer one after focused changes**: keep one candidate active and state bounded changes required before merge. +- **Combine selectively**: identify the destination PR and the exact ideas or tests worth transferring; avoid asking maintainers to reconcile entire competing implementations. +- **Replace all**: explain the simpler or more coherent implementation that should supersede every candidate. +- **Merge none**: the issue is invalid, negligible, unsupported, or none of the approaches justify completion cost. + +Do not split the decision into independent approvals. Competing PRs consume overlapping review and maintenance budgets, so recommend one path for the issue as a whole. + +## Maintainer comment drafts + +Always write maintainer comments in English, regardless of the assessment language. Produce a draft when the recommendation is to close, request evidence, request focused code changes, supersede a PR, or choose one competing PR over another. + +Keep each draft polite, direct, and copy-paste-ready. Usually use 60-160 words in one to three short paragraphs: + +1. Acknowledge the contribution or report. +2. Explain the decision with the smallest amount of decisive technical evidence. +3. Give the exact next action or the condition for reconsideration. + +Do not include internal labels such as `severity: low`, speculate about AI authorship or contributor intent, repeat the full review, or soften the message until the requested action becomes unclear. + +Do not ask contributors to choose maintainer-owned semantics. If two implementations are technically possible but one changes the SDK contract, decide the contract in the review and make the comment actionable. Use a short rationale such as "This keeps the new handler scoped to the existing raise site" or "This makes the handler name match all invalid final messages", then request the exact code and tests for that decision. + +### Close + +```text +Thanks for taking the time to investigate this.

Incoming calls are accepted through the Realtime Calls API, a triage agent answers with a fixed greeting, and handoffs route the caller to specialist agents (FAQ lookup and record updates) similar to the realtime UI demo. + +## Prerequisites + +- Python 3.10+ +- An OpenAI API key with Realtime API access +- A configured webhook secret for your OpenAI project +- A Twilio account with a phone number and Elastic SIP Trunking enabled +- A public HTTPS endpoint for local development (for example, [ngrok](https://ngrok.com/)) + +## Configure OpenAI + +1. In [platform settings](https://platform.openai.com/settings) select your project. +2. Create a webhook pointing to `https:///openai/webhook` with "realtime.call.incoming" event type and note the signing secret. The example verifies each webhook with `OPENAI_WEBHOOK_SECRET`. + +## Configure Twilio Elastic SIP Trunking + +1. Create (or edit) an Elastic SIP trunk. +2. On the **Origination** tab, add an origination SIP URI of `sip:proj_@sip.api.openai.com;transport=tls` so Twilio sends inbound calls to OpenAI. (The Termination tab always ends with `.pstn.twilio.com`, so leave it unchanged.) +3. Add at least one phone number to the trunk so inbound calls are forwarded to OpenAI. + +## Setup + +1. Install dependencies: + ```bash + uv pip install -r examples/realtime/twilio_sip/requirements.txt + ``` +2. Export required environment variables: + ```bash + export OPENAI_API_KEY="sk-..." + export OPENAI_WEBHOOK_SECRET="whsec_..." + ``` +3. (Optional) Adjust the multi-agent logic in `examples/realtime/twilio_sip/agents.py` if you want to change the specialist agents or tools. +4. Run the FastAPI server: + ```bash + uv run uvicorn examples.realtime.twilio_sip.server:app --host 0.0.0.0 --port 8000 + ``` +5. Expose the server publicly (example with ngrok): + ```bash + ngrok http 8000 + ``` + +## Test a Call + +1. Place a call to the Twilio number attached to the SIP trunk. +2. Twilio sends the call to `sip.api.openai.com`; OpenAI fires `realtime.call.incoming`, which this example accepts. +3. The triage agent greets the caller, then either keeps the conversation or hands off to: + - **FAQ Agent** – answers common questions via `faq_lookup_tool`. + - **Records Agent** – writes short notes using `update_customer_record`. +4. The background task attaches to the call and logs transcripts plus basic events in the console. + +You can edit `server.py` to change instructions, add tools, or integrate with internal systems once the SIP session is active. diff --git a/examples/realtime/twilio_sip/__init__.py b/examples/realtime/twilio_sip/__init__.py new file mode 100644 index 0000000..367fe35 --- /dev/null +++ b/examples/realtime/twilio_sip/__init__.py @@ -0,0 +1 @@ +"""OpenAI Realtime SIP example package.""" diff --git a/examples/realtime/twilio_sip/agents.py b/examples/realtime/twilio_sip/agents.py new file mode 100644 index 0000000..1afb3eb --- /dev/null +++ b/examples/realtime/twilio_sip/agents.py @@ -0,0 +1,94 @@ +"""Realtime agent definitions shared by the Twilio SIP example.""" + +from __future__ import annotations + +import asyncio + +from agents import function_tool +from agents.extensions.handoff_prompt import RECOMMENDED_PROMPT_PREFIX +from agents.realtime import RealtimeAgent, realtime_handoff + +# --- Tools ----------------------------------------------------------------- + + +WELCOME_MESSAGE = "Hello, this is ABC customer service.

[Follow-up Questions](#follow-up-questions) + +--- + +## Introduction + +Surfing is a dynamic sport that requires not only skill and technique but also the proper equipment. For beginners, the right surfboard can make the difference between a frustrating experience and one that builds confidence and enthusiasm. Many newcomers start with longboards due to their stability and ease of paddling; however, as skills develop, transitioning to a shorter board might be desirable for enhancing maneuverability and performance. This guide is designed for surfers who can already catch waves on an 11-foot board and are now considering stepping down to a more versatile option. + +The overarching goal of this document is to help beginners identify which surfboard characteristics are most important, including board length, width, thickness, volume, and materials, while also considering factors like weight distribution, buoyancy, and control. We will also take a look at board types that are particularly welcoming for beginners and discuss gradual transitioning strategies. + +--- + +## Board Types and Design Considerations + +Choosing a board involves understanding the variety of designs available. Below are the main types of surfboards that cater to beginners and transitional surfers: + +### Longboards and Mini-Mals + +Longboards, typically 8 to 11 feet in length, provide ample stability, smoother paddling, and are well-suited for wave-catching. Their generous volume and width allow beginners to build confidence when standing up and riding waves. Mini-mal or mini-malibus (often around 8 to 9 feet) are a popular bridge between the longboard and the more agile shortboard, offering both stability and moderate maneuverability, which makes them excellent for gradual progress. + +### Funboards and Hybrids + +Funboards and hybrid boards blend the benefits of longboards and shortboards. They typically range from 6’6" to 8’0" in length, with extra volume and width that help preserve stability while introducing elements of sharper turning and improved agility. Hybrids are particularly helpful for surfers transitioning from longboards, as they maintain some of the buoyancy and ease of catching waves, yet offer a taste of the performance found in smaller boards. + +### Shortboards + +Shortboards emphasize performance, maneuverability, and a more responsive ride. However, they have less volume and require stronger paddling, quicker pop-up techniques, and more refined balance. For beginners, moving to a traditional shortboard immediately can be challenging. It is generally advised to make a gradual transition, potentially starting with a funboard or hybrid before making a direct leap to a performance shortboard. + +--- + +## Key Board Dimensions and Features + +When selecting a beginner surfboard, several key dimensions and features drastically affect performance, ease of learning, and safety: + +### Length and Width + +- **Length**: Starting with an 8 to 9-foot board is ideal. Longer boards offer enhanced stability and improved paddling capabilities. Gradual downsizing is recommended if you plan to move from an 11-foot board. +- **Width**: A board with a width over 20 inches provides greater stability and facilitates balance, especially vital for beginners. + +### Thickness and Volume + +- **Thickness**: Typically around 2.5 to 3 inches. Thicker decks increase buoyancy, allowing the surfer to paddle easier while catching waves. +- **Volume**: Measured in liters, volume is critical in understanding a board's flotation capacity. Higher volumes (e.g., 60-100 liters) are essential for beginners as they make the board more forgiving and stable. Suitable volumes might vary according to the surfer’s weight and experience level. + +### Nose and Tail Shape + +- **Nose Shape**: A wide, rounded nose expands the board’s planing surface, which can help in catching waves sooner and maintaining stability as you ride. +- **Tail Design**: Square or rounded tails are generally recommended as they enhance stability and allow for controlled turns, essential during the learning phase. + +### Rocker + +- **Rocker**: This is the curvature of the board from nose to tail. For beginners, a minimal or relaxed rocker provides better stability and ease during paddling. A steeper rocker might be introduced progressively as the surfer’s skills improve. + +--- + +## Materials: Soft-Top vs. Hard-Top Boards + +The material composition of a surfboard is a crucial factor in determining its performance, durability, and safety. Beginners have two primary choices: + +### Soft-Top (Foam) Boards + +Soft-top boards are constructed almost entirely from foam. Their attributes include: + +- **Safety and Forgiveness**: The foam construction minimizes injury upon impact which is advantageous for beginners who might fall frequently. +- **Stability and Buoyancy**: These boards typically offer greater buoyancy due to their softer material and thicker construction, easing the initial learning process. +- **Maintenance**: They often require less maintenance—there is typically no need for waxing and they are more resistant to dings and scratches. + +However, as a surfer’s skills progress, a soft-top might limit maneuverability and overall performance. + +### Hard-Top Boards + +Hard-tops, in contrast, offer a more traditional surfboard feel. They generally rely on a foam core encased in resin, with two prevalent combinations: + +- **PU (Polyurethane) Core with Polyester Resin**: This combination gives a classic feel and is relatively economical; however, these boards can be heavier and, as they age, more prone to damage. +- **EPS (Expanded Polystyrene) Core with Epoxy Resin**: Lightweight and durable, EPS boards are often more buoyant and resistant to damage, although they usually carry a higher price tag and may be less forgiving. + +Deciding between soft-top and hard-top boards often depends on a beginner’s progression goals, overall comfort, and budget constraints. + +--- + +## Tips for Transitioning from Longboards to Shorter Boards + +For surfers who have mastered the basics on an 11-foot board, the transition to a shorter board requires careful consideration, patience, and incremental changes. Here are some key tips: + +### Gradual Downsizing + +Experts recommend reducing the board length gradually—by about a foot at a time—to allow the body to adjust slowly to a board with less buoyancy and more responsiveness. This process helps maintain wave-catching ability and reduces the shock of transitioning to a very different board feel. + +### Strengthening Core Skills + +Before transitioning, make sure your surfing fundamentals are solid. Focus on practicing: + +- **Steep Take-offs**: Ensure that your pop-up is swift and robust to keep pace with shorter boards that demand a rapid transition from paddling to standing. +- **Angling and Paddling Techniques**: Learn to angle your takeoffs properly to compensate for the lower buoyancy and increased maneuverability of shorter boards. + +### Experimenting with Rentals or Borrowed Boards + +If possible, try out a friend’s shorter board or rent one for a day to experience firsthand the differences in performance. This practical trial can provide valuable insights and inform your decision before making a purchase. + +--- + +## Budget and Pricing Options + +Surfboards are available across a range of prices to match different budgets. Whether you are looking for an affordable beginner board or a more expensive model that grows with your skills, it’s important to understand what features you can expect at different price points. + +### Budget-Friendly Options + +For those on a tight budget, several entry-level models offer excellent value. Examples include: + +- **Wavestorm 8' Classic Pinline Surfboard**: Priced affordably, this board is popular for its ease of use, ample volume, and forgiving nature. Despite its low cost, it delivers the stability needed to get started. +- **Liquid Shredder EZ Slider Foamie**: A smaller board catering to younger or lighter surfers, this budget option provides easy paddling and a minimal risk of injury due to its soft construction. + +### Moderate Price Range + +As you move into the intermediate range, boards typically become slightly more specialized in their design, offering features such as improved stringer systems or versatile fin setups. These are excellent for surfers who wish to continue progressing their skills without compromising stability. Many surfboard packages from retailers also bundle a board with essential accessories like board bags, leashes, and wax for additional savings. + +### Higher-End Models and Transitional Packages + +For surfers looking for durability, performance, and advanced design features, investing in an EPS/epoxy board might be ideal.

[Follow-up Questions](#follow-up-questions) + +--- + +## Introduction + +Surfing is a dynamic sport that requires not only skill and technique but also the proper equipment. For beginners, the right surfboard can make the difference between a frustrating experience and one that builds confidence and enthusiasm. Many newcomers start with longboards due to their stability and ease of paddling; however, as skills develop, transitioning to a shorter board might be desirable for enhancing maneuverability and performance. This guide is designed for surfers who can already catch waves on an 11-foot board and are now considering stepping down to a more versatile option. + +The overarching goal of this document is to help beginners identify which surfboard characteristics are most important, including board length, width, thickness, volume, and materials, while also considering factors like weight distribution, buoyancy, and control. We will also take a look at board types that are particularly welcoming for beginners and discuss gradual transitioning strategies. + +--- + +## Board Types and Design Considerations + +Choosing a board involves understanding the variety of designs available. Below are the main types of surfboards that cater to beginners and transitional surfers: + +### Longboards and Mini-Mals + +Longboards, typically 8 to 11 feet in length, provide ample stability, smoother paddling, and are well-suited for wave-catching. Their generous volume and width allow beginners to build confidence when standing up and riding waves. Mini-mal or mini-malibus (often around 8 to 9 feet) are a popular bridge between the longboard and the more agile shortboard, offering both stability and moderate maneuverability, which makes them excellent for gradual progress. + +### Funboards and Hybrids + +Funboards and hybrid boards blend the benefits of longboards and shortboards. They typically range from 6’6" to 8’0" in length, with extra volume and width that help preserve stability while introducing elements of sharper turning and improved agility. Hybrids are particularly helpful for surfers transitioning from longboards, as they maintain some of the buoyancy and ease of catching waves, yet offer a taste of the performance found in smaller boards. + +### Shortboards + +Shortboards emphasize performance, maneuverability, and a more responsive ride. However, they have less volume and require stronger paddling, quicker pop-up techniques, and more refined balance. For beginners, moving to a traditional shortboard immediately can be challenging. It is generally advised to make a gradual transition, potentially starting with a funboard or hybrid before making a direct leap to a performance shortboard. + +--- + +## Key Board Dimensions and Features + +When selecting a beginner surfboard, several key dimensions and features drastically affect performance, ease of learning, and safety: + +### Length and Width + +- **Length**: Starting with an 8 to 9-foot board is ideal. Longer boards offer enhanced stability and improved paddling capabilities. Gradual downsizing is recommended if you plan to move from an 11-foot board. +- **Width**: A board with a width over 20 inches provides greater stability and facilitates balance, especially vital for beginners. + +### Thickness and Volume + +- **Thickness**: Typically around 2.5 to 3 inches. Thicker decks increase buoyancy, allowing the surfer to paddle easier while catching waves. +- **Volume**: Measured in liters, volume is critical in understanding a board's flotation capacity. Higher volumes (e.g., 60-100 liters) are essential for beginners as they make the board more forgiving and stable. Suitable volumes might vary according to the surfer’s weight and experience level. + +### Nose and Tail Shape + +- **Nose Shape**: A wide, rounded nose expands the board’s planing surface, which can help in catching waves sooner and maintaining stability as you ride. +- **Tail Design**: Square or rounded tails are generally recommended as they enhance stability and allow for controlled turns, essential during the learning phase. + +### Rocker + +- **Rocker**: This is the curvature of the board from nose to tail. For beginners, a minimal or relaxed rocker provides better stability and ease during paddling. A steeper rocker might be introduced progressively as the surfer’s skills improve. + +--- + +## Materials: Soft-Top vs. Hard-Top Boards + +The material composition of a surfboard is a crucial factor in determining its performance, durability, and safety. Beginners have two primary choices: + +### Soft-Top (Foam) Boards + +Soft-top boards are constructed almost entirely from foam. Their attributes include: + +- **Safety and Forgiveness**: The foam construction minimizes injury upon impact which is advantageous for beginners who might fall frequently. +- **Stability and Buoyancy**: These boards typically offer greater buoyancy due to their softer material and thicker construction, easing the initial learning process. +- **Maintenance**: They often require less maintenance—there is typically no need for waxing and they are more resistant to dings and scratches. + +However, as a surfer’s skills progress, a soft-top might limit maneuverability and overall performance. + +### Hard-Top Boards + +Hard-tops, in contrast, offer a more traditional surfboard feel. They generally rely on a foam core encased in resin, with two prevalent combinations: + +- **PU (Polyurethane) Core with Polyester Resin**: This combination gives a classic feel and is relatively economical; however, these boards can be heavier and, as they age, more prone to damage. +- **EPS (Expanded Polystyrene) Core with Epoxy Resin**: Lightweight and durable, EPS boards are often more buoyant and resistant to damage, although they usually carry a higher price tag and may be less forgiving. + +Deciding between soft-top and hard-top boards often depends on a beginner’s progression goals, overall comfort, and budget constraints. + +--- + +## Tips for Transitioning from Longboards to Shorter Boards + +For surfers who have mastered the basics on an 11-foot board, the transition to a shorter board requires careful consideration, patience, and incremental changes. Here are some key tips: + +### Gradual Downsizing + +Experts recommend reducing the board length gradually—by about a foot at a time—to allow the body to adjust slowly to a board with less buoyancy and more responsiveness. This process helps maintain wave-catching ability and reduces the shock of transitioning to a very different board feel. + +### Strengthening Core Skills + +Before transitioning, make sure your surfing fundamentals are solid. Focus on practicing: + +- **Steep Take-offs**: Ensure that your pop-up is swift and robust to keep pace with shorter boards that demand a rapid transition from paddling to standing. +- **Angling and Paddling Techniques**: Learn to angle your takeoffs properly to compensate for the lower buoyancy and increased maneuverability of shorter boards. + +### Experimenting with Rentals or Borrowed Boards + +If possible, try out a friend’s shorter board or rent one for a day to experience firsthand the differences in performance. This practical trial can provide valuable insights and inform your decision before making a purchase. + +--- + +## Budget and Pricing Options + +Surfboards are available across a range of prices to match different budgets. Whether you are looking for an affordable beginner board or a more expensive model that grows with your skills, it’s important to understand what features you can expect at different price points. + +### Budget-Friendly Options + +For those on a tight budget, several entry-level models offer excellent value. Examples include: + +- **Wavestorm 8' Classic Pinline Surfboard**: Priced affordably, this board is popular for its ease of use, ample volume, and forgiving nature. Despite its low cost, it delivers the stability needed to get started. +- **Liquid Shredder EZ Slider Foamie**: A smaller board catering to younger or lighter surfers, this budget option provides easy paddling and a minimal risk of injury due to its soft construction. + +### Moderate Price Range + +As you move into the intermediate range, boards typically become slightly more specialized in their design, offering features such as improved stringer systems or versatile fin setups. These are excellent for surfers who wish to continue progressing their skills without compromising stability. Many surfboard packages from retailers also bundle a board with essential accessories like board bags, leashes, and wax for additional savings. + +### Higher-End Models and Transitional Packages + +For surfers looking for durability, performance, and advanced design features, investing in an EPS/epoxy board might be ideal. Although they come at a premium, these boards are lightweight, strong, and customizable with various fin configurations. Some options include boards from brands like South Bay Board Co. and ISLE, which combine high-quality construction with beginner-friendly features that help mediate the transition from longboard to shortboard performance. + +--- + +## Recommended Models and Buying Options + +Based on extensive research and community recommendations, here are some standout models and tips on where to buy: + +### Recommended Models + +- **South Bay Board Co. 8'8" Heritage**: Combining foam and resin construction, this board is ideal for beginners who need stability and a forgiving surface.

The file stems from the agency’s audited financial system and is validated against the Governmentwide Treasury Account Symbol Adjusted Trial Balance System (GTAS). File A includes data on total budgetary resources and total spending, including obligations and outlays, by Treasury Account Symbol (TAS). It also provides the relevant budget function associated with spending. +When you see a reference to Account Balance (File A) on the site, the reference is to the dataset comprising all agency Files A submissions and not one specific agency file. + +## Account Breakdown by Award (File C) + +Account Breakdown by Award (File C) is one of the three files that each agency publishes to USAspending.gov in its financial data submission each month (or quarter for some agencies). The file stems from the agency’s audited financial system and includes data on award spending only (i.e., excludes non-award spending). Account Breakdown by Award (File C) provides details such as the timing, type, and recipient for each award. +When you see a reference to Account Breakdown by Award (File C) on the site, the reference is to the dataset comprising all agency Files C and not one specific agency file. + +## Account Breakdown by Program Activity & Object Class (File B) + +Account Breakdown by Program Activity & Object Class (File B) is one of the three files that each agency publishes to USAspending.gov in its financial data submission each month (or quarter for some agencies). The file stems from the agency’s audited financial system and includes data on total budgetary spending, including obligations and outlays, by Treasury Account Symbol. Like Account Balances (File A), this file provides the relevant budget function associated with spending. In contrast with Account Balances (File A) this file also includes the relevant object class and program activity. +When you see a reference to Account Breakdown by Program Activity & Object Class (File B) on the site, the reference is to the dataset comprising all agency Files B and not one specific agency file. + +## Acquisition of Assets + +This major object class includes an agency’s procurement of assets, including those that have lost value (depreciated). Some examples of assets, according to this definition, include equipment, land, physical structures, investments, and loans. + +**Official definition:** This major object class covers object classes 31.0 through 33.0. Include +capitalized (depreciated) assets and non-capitalized assets. This includes: +31.0 Equipment +32.0 Land and structures +33.0 Investments and loans + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Action Date + +The date the action being reported (for prime award transactions or sub-awards) was issued or signed by the Government, or a binding agreement was reached. Because award obligations are tied to action dates, any search for spending data on USAspending will search by this data element rather than by Period of Performance dates. + +## Action Type + +Provides information on the type of change made to an award. For example, the change may be the result of a continuation, revision, and/or adjustment to completed project. + +**Official definition:** Description (and corresponding code) that provides information on any changes made to the Federal prime award. There are typically multiple actions for each award. + +(Note: This definition encompasses current data elements ‘Type of Action’ for financial assistance and ‘Reason for Modification’ for procurement) + +## Agency + +On this website, we use the term agency to mean any federal department, commission, or other U.S. government entity. Agencies can have multiple sub-agencies. For example, the National Park Service is a sub-agency of the U.S. Department of the Interior. + +## Agency Identifier + +Identifies the agency responsible for a Treasury account. This is a 3-digit number that is a part of a Treasury Account Symbol (TAS). + +**Official definition:** The agency code identifies the department or agency that is responsible for the account. + +## Allocation Transfer Agency (ATA) Identifier + +Identifies an agency that receives funds through an allocation (non-expenditure) transfer. This is a 3-digit number that is a part of a Treasury Account Symbol (TAS). + +**Official definition:** The allocation agency identifies the department or agency that is receiving funds through an allocation (non-expenditure) transfer. + +## Appropriation + +The process by which Congress designates and approves spending for a specific purpose (e.g., a project or program). Most government spending is determined through appropriation bills each year. These bills must be passed by Congress and signed by the President. + +When an appropriation is not passed by Congress before the beginning of the fiscal year, a “continuing resolution” (often referred to as a “CR”) may be enacted to avoid a government shutdown. A CR is a law that provides stopgap funding for agencies until their regular appropriations are passed. + +## Appropriation Account + +When Congress passes a law, it often gives an agency authority to carry out a project. When this happens, Congress may set aside money for the project. An appropriation account tracks the money, much like a bank account. The appropriation account number (like a bank account number) is called a Treasury Account Symbol (TAS). + +**Official definition:** The basic unit of an appropriation generally reflecting each unnumbered paragraph in an appropriation act. An appropriation account typically encompasses a number of activities or projects and may be subject to restrictions or conditions applicable to only the account, the appropriation act, titles within an appropriation act, other appropriation acts, or the Government as a whole. + +An appropriations account is represented by a TAFS created by Treasury in consultation with OMB. + +(defined in OMB Circular A-11) + +## Assistance Listings (CFDA Program) + +Assistance Listings, previously known as "CFDA programs", provide a full listing of federal programs that are available to organizations, government agencies (state, local, tribal), U.S. territories, and individuals who are authorized to do business with the government. An Assistance Listing program can be a project, service, or activity. Each program has a unique, 5-digit number in the form of XX.XXX. The first two digits represent the funding agency. The last three digits represent the program. + +Examples of Assistance Listings include: + +* Social Security Retirement Insurance (96.002) +* Medicare Supplementary Medical Insurance (93.774) +* Supplemental Nutrition Assistance Program (10.551) +* Highway Planning and Construction (20.205) +* National School Lunch Program (10.555) + +**Official definition:** The number assigned to an Assistance Listing in the Catalog of Federal Domestic Assistance (CFDA) and SAM.gov. + +The title of the Assistance Listing under which the Federal award was funded in the Catalog of Federal Domestic Assistance (CFDA) and SAM.gov. + +## Availability Type Code + +Within a Treasury Account Symbol (TAS), this one-letter code Identifies the availability (or time period) for obligations to be made on the appropriation account. A TAS will have an “X” if there is an unlimited or indefinite period to incur new obligations. + +**Official definition:** In appropriations accounts, the availability type code identifies an unlimited period to incur new obligations; this is denoted by the letter X. + +## Award + +Money the federal government has promised to pay a recipient. Funding may be awarded to a company, organization, government entity (i.e., state, local, tribal, federal, or foreign), or individual. It may be obligated (promised) in the form of a contract, grant, loan, insurance, direct payment, etc. + +## Award Amount + +The amount that the federal government has promised to pay (obligated) a recipient, because it has signed a contract, awarded a grant, etc. + +**Official definition:** The cumulative amount obligated by the Federal Government for an award, which is calculated by USAspending.gov. + +For procurement and financial assistance awards except loans, this is the sum of Federal Action Obligations. + +For loans or loan guarantees, this is the Original Subsidy Cost. + +## Award ID + +A unique identification number for each individual award. + +**Official definition:** The unique identifier of the specific award being reported, i.e. Federal Award Identification Number (FAIN) for financial assistance and Procurement Instrument Identifier (PIID) for procurement. + +## Award Type + +The federal government can distribute funding in several forms, including contracts, grants, loans, insurance, and direct payments. Award Type is a classification that provides more information about the structure of the award. Examples include: + +- Purchase Order (a type of contract) +- Definitive Contract (a type of contract) +- Block Grant (a type of grant) +- Direct Loan (a type of loan) + +**Official definition:** Description (and corresponding code) that provides information to distinguish type of contract, grant, or loan and providers the user with more granularity into the method of delivery of the outcomes. + +## Awarding Agency + +The Awarding Agency is the agency that issues and administers the award. This agency usually pays for the funding out of its own budget. In some cases, the money is financed by another agency, called the Funding Agency. + +**Official definition:** The name and code associated with a department or establishment of the Government as used in the Treasury Account Fund Symbol (TAFS). + +## Awarding Office + +The office within an agency that issues and administers the award. + +**Official definition:** Name and identifier of the level n organization that awarded, executed or is otherwise responsible for the transaction. + +## Awarding Sub-Agency + +The Awarding Sub Agency is the sub agency that issues and administers the award. For example, the Internal Revenue Service (IRS) is a sub agency of the Department of the Treasury. + +**Official definition:** Name and identifier of the level 2 organization that awarded, executed or is otherwise responsible for the transaction. + +## Awards Data (File D) + +Awards Data is ingested up to daily from government-wide systems where agencies submit financial assistance and procurement data. Because it comprises two separate datasets, it is sometimes referred to as Procurement Data (File D1) and Assistance Data (File D2). Awards Data is separate from the financial data submissions that agencies publish to USAspending.gov each month or quarter (the submissions that include Files A, B, and C). Data from File D1/D2 supplements award data found in Account Breakdown by Award (File C) to provide a full picture of award spending. +When you see a reference to File D on the site, it refers to the up-to-date set of all agencies’ procurement (File D1) and assistance (File D2) datasets and not one specific agency’s files. + +## Balance Brought Forward + +Funds that were not spent (obligated or outlaid) in previous years and are authorized to be spent in the current year. + +**Official definition:** The definition for this element appears in Appendix F of OMB Circular A-11 issued June 2015; a brief summary from A-11 appears below. For unexpired accounts: Amount of unobligated balance of appropriations or other budgetary resources carried forward from the preceding year and available for obligation without new action by Congress. For expired accounts: Amount of expired unobligated balances available for upward adjustments of obligations. + +## Base Transaction Action Date + +The action date of the original Prime Award Transaction of a Prime Award Summary. Note that this date may be different from the Period of Performance Start Date. Because award obligations are tied to action dates, any search for spending data on USAspending will search by this data element rather than by Period of Performance dates. + +## Base Transaction Description + +A brief description of the purpose of the award. + +**Official definition:** For procurement awards: Per the FPDS data dictionary, a brief, summary level, plain English, description of the contract, award, or modification. Additional information: the description field may also include abbreviations, acronyms, or other information that is not plain English such as that required by OMB policies (CARES Act, etc). + +For financial assistance awards: A plain language description of the Federal award purpose; activities to be performed; deliverables and expected outcomes; intended beneficiary(ies); and subrecipient activities if known/specified at the time of award. + +## Basic Ordering Agreement (BOA) + +A Basic Ordering Agreement (BOA) is a type of Indefinite Delivery Vehicle (IDV). It is not a contract; it is a written understanding between government and contractor. It details the supplies or services offered. It also details pricing and delivery for future orders. + +BOA's can speed up contracting when requirements are uncertain. For instance, when specifications, quantities, and prices are not yet known. + +These agreements can also help the government achieve economies of scale for part orders. For the contractor, they can lessen lead-time, enable a larger inventory investment, and lessen old inventory. + +## Beginning Period of Availability + +Identifies the first year that an appropriation account may incur new obligations. This is for annual and multi-year funds only. This is a 4-digit number representing the year (e.g., 2017). It is a part of a Treasury Account Symbol (TAS). + +**Official definition:** In annual and multi-year funds, the beginning period of availability identifies the first year of availability under law that an appropriation account may incur new obligations. + +## Blanket Purchase Agreement (BPA) + +A Blanket Purchase Agreement (BPA) is a method federal agencies use to make repeat purchases of supplies or services. A type of Indefinite Delivery Vehicle (IDV), a BPA operates by setting up a "charge account" with trusted vendors. Both agencies and vendors often prefer BPAs because they help speed up the process of repeated purchases. Once a BPA is set up, repeat purchases are easy for both sides. + +A BPA is an agreement with an individual agency, meaning only a handful of offices can place orders on a BPA. A BPA can be awarded to a set of vendors, who will then be able to bid on upcoming orders. A BPA can be set up with or without General Services Administration (GSA) schedules. Without GSA schedules, orders are capped at the Simplified Acquisition Threshold (SAT) of $100,000. + +Examples of BPAs: + +- Agency A establishes a BPA with a computer manufacturer for repeat laptop purchases +- Agency B establishes a BPA with a graphic design agency for design of brochures and event signage + +## Block Grant + +Block grants are awarded by the federal government to state and local governments for broadly defined purposes — for example, social services or community development. + +**Official definition:** Block grants are given primarily to general purpose governmental units in accordance with a statutory formula. Such grants can be used for a variety of activities within a broad functional area. Examples of federal block grant programs are the Omnibus Crime Control and Safe Streets Act of 1968, the Housing and Community Development Act of 1974, and the grants to states for social services under title XX of the Social Security Act. + +## Budget Authority + +A federal agency is only allowed to spend money if Congress provides the authority by law for that spending. That permission to spend is called “budget authority.” + +Budget authority can be granted through an appropriation law, which specifies a purpose, usually a maximum amount of money, and a set time period. Budget authority can also be granted for spending unused funds from a previous year, or to spend money that the agency takes in (e.g., the National Park Service is authorized to spend fees collected for park admission regardless of the amount). + +**Official definition:** The total amount of all obligation budget authority including unobligated balances carried forward, adjustments to unobligated balances carried forward, appropriated amounts, and other budgetary resources, as of the reported date. + +## Budget Authority Appropriated + +A provision of law (not necessarily in an appropriations act) authorizing an account to incur obligations and to make outlays for a given purpose. Usually, but not always, an appropriation provides budget authority. + +(defined in OMB Circular A-11) + +## Budget Function + +The federal budget is divided into approximately 20 categories, known as budget functions. These categories organize federal spending into topics based on the major purpose the spending serves (e.g., National Defense, Transportation, Health). + +These are further broken down into budget sub functions. + +## Budget Sub-Function + +The federal budget is divided into functions and sub functions. These categories organize federal spending into topics based on the major purpose the spending serves. There are about 20 major functions (e.g., National Defense, Transportation, Health). Most of these functions are further divided into sub functions. + +For example, the budget function for Health is divided into sub functions for Health care services, Health research and training, and Consumer and occupational health and safety. + +## Budgetary Resources + +Budgetary resources mean amounts available to incur obligations in a given year. Budgetary resources consist of new budget authority (from appropriations, borrowing authority, contract authority, or offsetting collections) and unobligated balances of budget authority provided in previous years. On this website, budgetary resources do not include financing accounts, which are a type of treasury account used to finance federal loans and are not considered spending per Office of Management and Budget (OMB) policy. For the purposes of USASpending.gov, “funding” represents “budgetary resources”. + +Budgetary resources include financial transfers between Government accounts. Financial transfers are financial interchanges between Federal Government accounts that are not an exchange for goods and services. For example, an expenditure transfer that shifts budgetary resources between a General Fund account, (e.g., Payment to Highway Trust Fund) and a trust fund (e.g., Highway Trust Fund) is considered a financial transfer. For financial transfers, budgetary resources are shown in both accounts. + +## Clinger-Cohen Act + +The Clinger-Cohen Act (CCA) of 1996 is a federal law designed to improve the way the federal government acquires, uses, and disposes of IT. It strives to make IT purchases more strategic. + +**Official definition:** A code indicating the funding office has certified that the information technology purchase meets the planning requirements in 40 USC 11312 and 40 USC 11313. + +## Construction Wage Rate Requirements + +Indicates whether the transaction is subject to the Construction Wage Rate Requirements. The clause is 52.222-6 "Construction Wage Rate Requirements" -that goes with Wage Rate Requirements (Construction) (formerly Davis-Bacon Act). + +## Contract + +An agreement between the federal government and a prime recipient to provide goods and services for a fee. + +**Official definition:** Contract means a mutually binding legal relationship obligating the seller to furnish the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the government to an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders or task letters issued under basic ordering agreements; letter contracts; orders, such as purchase orders, under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications. Contracts do not include grants and cooperative agreements covered by 31 U.S.C. 6301, et seq. + +## Contract Pricing Type + +Payment model for a contract. Each has a different way of accounting for costs, fees, and profits. Contract pricing types include: + +- Fixed Price Redetermination +- Fixed Price Level of Effort +- Firm Fixed Price +- Fixed Price with Economic Price Adjustment +- Fixed Price Incentive +- Fixed Price Award Fee +- Cost Plus Award Fee +- Cost No Fee +- Cost Sharing +- Cost Plus +- Fixed Fee +- Cost Plus Incentive Fee +- Time and Materials +- Labor Hours + +**Official definition:** The type of contract as defined in FAR Part 16 that applies to this procurement. + +## Contractor + +A business, organization, or agency that receives funding and/or performs work on a contract. A contractor may be a corporation, small business, university, non-profit, sole proprietor, or other entity. When a company has a contract with the U.S. government, they may hire another company to perform part of the work. When this happens, the company who received the award is called the prime contractor. The company hired by the prime is called the sub-contractor. + +## Contractual Services and Supplies + +This major object class includes services or supplies purchased to support the fulfillment of government activities during a specified contract period. Some examples include transportation of government personnel and supplies, rent and other utilities, rental payments made to GSA, printing and reproduction costs, and operations/maintenance costs for federal facilities. + +These items are not equivalent to the Federal Acquisition Regulation (FAR) federal contract award spending and will not match total contract award spending on USAspending.gov. + +**Official definition:** This major object class covers purchases of contractual services and supplies in object classes 21.0 through 26.0, including: +21.0 Travel and transportation of persons +22.0 Transportation of things, Rent, Communications, and Utilities +23 Rent, Communications, and Utilities +23.1 Rental payments to GSA +23.2 Rental payments to others +23.3 Communications, utilities, and miscellaneous charges +24.0 Printing and reproduction +25 Other contractual services +25.1 Advisory and assistance services +25.2 Other services from non-Federal sources +25.3 Other goods and services from Federal sources +25.4 Operation and maintenance of facilities +25.5 Research and development contracts +25.6 Medical care +25.7 Operation and maintenance of equipment +25.8 Subsistence and support of persons +26.0 Supplies and materials + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Cooperative Agreement + +Grant awarded to provide assistance. It is characterized by extended involvement between recipient and agency. It requires substantial oversight by the agency, and includes reporting requirements. + +## Current Award Amount + +The amount of money that the government has promised (obligated) to pay a recipient for a contract. This means the base amount and any exercised options. + +**Official definition:** For procurement, the total amount obligated to date on a contract, including the base and exercised options. + +## Definitive Contract + +A Definitive Contract is a mutually binding legal relationship obligating the seller to provide the supplies or services (including construction) and the buyer to pay for them. It includes all types of commitments that obligate the Government to an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition to bilateral instruments, contracts include (but are not limited to) awards and notices of awards; job orders, or task letters, issued under basic ordering agreements; letter contracts; orders, such as purchase orders, under which the contract becomes effective by written acceptance or performance; and bilateral contract modifications. + +## Delivery Order Contract + +An Indefinite Quantity Contract for supplies (not services) is sometimes referred to as a Delivery Order Contract. With this type of contract, the government promises to buy supplies over a period of time from a vendor. Instead of an exact amount, it sets a quantity range with a minimum and maximum. + +## Deobligation + +The cancellation or downward adjustment of previously obligated funds. Agencies deobligate funds to decrease the amount available under an award. Deobligated funds may be reobligated within the period of availability of the appropriation. + +## Direct Loan + +Direct loan means a disbursement of funds by the Government to a non-Federal borrower under a contract that requires the repayment of such funds with or without interest. The term also includes certain equivalent transactions that extend credit. + +## Direct Payment + +A cash payment made by the federal government to an individual, a private firm, or another private institution. + +## Direct Payment for Specified Use + +Financial assistance provided by the federal government directly to individuals, private firms, and other private institutions for a particular activity. To receive this assistance, the recipient must perform certain agreed-upon activities and meet certain milestones. Direct payments don’t include solicited contracts for the procurement of goods and services for the government. + +**Official definition:** Includes financial assistance from the Federal government provided directly to individuals, private firms, and other private institutions to encourage or subsidize a particular activity by conditioning the receipt of the assistance on a particular performance by the recipient. + +## Direct Payment with Unrestricted Use + +Financial assistance provided by the federal government directly to beneficiaries who meet certain federal eligibility requirements. This type of assistance doesn’t place any restrictions on how the recipient spends the money. Some examples of direct payments include retirement, pension, and compensatory programs. + +## Disaster Emergency Fund Code (DEFC) + +Disaster Emergency Fund Code (DEFC) is used to track the spending of funding for disasters and emergencies such as COVID-19. Each code links to one or more legislative bills that authorized the funding. + +**Official definition:** The Office of Management and Budget (OMB), working with the Department of Treasury’s Fiscal Service, has identified a Government-wide Treasury Account Symbol Adjusted Trial Balance System (GTAS) attribute called ‘Disaster Emergency Fund Code (DEFC)’ to track appropriations classified as disaster or emergency. This code applies to the budgetary resources, obligations incurred, unobligated and obligated balances, and outlays that result from these appropriations. + + +As established in Memorandum M-18-08, the domain value set for DEFC is a single letter from ‘A’ to ‘Z’. The default domain value for all funding without disaster or emergency designation is ‘Q’. OMB assigns a new DEFC domain value from the set to each enacted appropriation with disaster or emergency funding. The corresponding domain title for each DEFC domain value identifies the associated public law number(s) and whether the funding is disaster or emergency. + + +Memorandum M-20-21 amended the above to allow agencies to use DEFC to meet reporting requirements for COVID-19 supplemental funding, which required tracking of funds not designated as emergency. + + +Agencies use the following DEFC domain values and titles for COVID-19 supplemental funding: + +- **DEFC ‘L’** Public Law 116-123, designated as emergency +- **DEFC ‘M’** Public Law 116-127, designated as emergency +- **DEFC ‘N’** Public Law 116-136, designated as emergency +- **DEFC ‘O’** Public Law 116-136, Public Law 116-139, and Public Law 116-260, not designated as emergency +- **DEFC ‘P’** Public Law 116-139, designated as emergency +- **DEFC ‘U’** Public Law 116-260, designated as emergency +- **DEFC ‘V’** Public Law 117-2, American Rescue Plan Act of 2021, not designated as emergency + + +Note that the National Interest Action (NIA) code is also used to track COVID-19 spending. However, it only applies to procurement actions (i.e., contracts) and is not necessarily tied to COVID-19 supplemental appropriations. Thus, awards with the COVID-19 NIA value may not have a COVID-19 DEFC value, and vice versa. + +## DOD Claimant Program Code + +Department of Defense (DOD) code that designates a grouping of supplies, construction, or other services. Each code has letters and numbers. + +**Official definition:** A claimant program number designates a grouping of supplies, construction, or other services. + +## DUNS + +DUNS stands for Data Universal Numbering System. It is a unique 9-digit identification number assigned to a company or organization by Dun & Bradstreet, Inc. A DUNS is required to register in the System for Award Management (SAM). An organization must be registered in SAM (and obtain a DUNS) to do business with the federal government. There is a separate DUNS number for each business location in the Dun & Bradstreet database. The DUNS number is random, and specific digits have no significance. + +**Official definition:** The unique identification number for an awardee or recipient. Currently the identifier is the 9-digit number assigned by Dun & Bradstreet referred to as the DUNS® number. + +## Ending Period of Availability + +Identifies the last year that an appropriation account may incur new obligations. This is for annual and multi-year funds only. This is a 4-digit number representing the year (e.g., 2018). It is a part of a Treasury Account Symbol (TAS). + +**Official definition:** In annual and multi-year funds, the end period of availability identifies the last year of funds availability under law that an appropriation account may incur new obligations. + +## Extent Competed + +A code that represents the competitive nature of the contract. Values include: + +- A = Full and open competition (competitive proposal, no sources excluded) +- B = Not available for competition +- C = Not competed +- D = Full and open competition after exclusion of sources +- E = Follow-on to competed action (a follow-on to an existing competed contract) +- F = Competed under Simplified Acquisition Threshold (SAP) +- G = Not competed under Simplified Acquisition Threshold (SAP) + +**Official definition:** A code that represents the competitive nature of the contract. +[Read the Federal Procurement Data System definition](https://www.fpds.gov/help/Extent_Competed.htm). + +## Face Value of Loan + +Face value of a loan is the total amount of the loan, and the amount that agencies have directly issued (for direct loans) or facilitated by compensating the lender if the borrower defaults (for loan guarantees). + +Since loans are expected to be paid back, in budgetary terms, the face value of a loan is not considered spending and is not included in any obligation or outlay figure. However, because not all loans are repaid, they do have costs to the government. The government’s calculation of these costs is called subsidy cost. + +**Official definition:** The face value of the direct loan or loan guarantee. + +## FAIN + +An identification code assigned to a specific financial assistance award by an agency for tracking purposes. The FAIN is tied to that award (and all future modifications to that award) throughout the award's life. Within an agency, FAINs are unique; a new award must be issued a new FAIN. FAIN stands for Federal Award Identification Number, though the digits may be both letters and numbers. + +**Official definition:** The Federal Award Identification Number (FAIN) is the unique ID within the Federal agency for each financial assistance award. + +## Federal Account + +Federal Accounts refer to the set of Treasury spending accounts that are grouped under a given "Federal Account Symbol." On this website we group them by their agency identifier (3-digit code) and Main Account code (4-digit code). + +## Federal Action Obligation + +Amount of Federal Government’s obligation, de-obligation, or liability, in dollars, for an award transaction. + +## Federal Supply Schedule (FSS) + +The Federal Supply Schedule (FSS) is a listing of contractors that have been awarded a contract by GSA that can be used by all federal agencies. This is also known as a Multiple Award Schedule (MAS). + +## Financial Assistance + +A federal program, service, or activity that directly aids organizations, individuals, or state/local/tribal governments. Sectors include education, health, public safety and public welfare - to name a few. Financial assistance is distributed in many forms, including grants, loans, direct payments, or insurance. + +## Fiscal Year (FY) + +The fiscal year is an accounting period that spans 12 months. For the federal government, it runs from October 1 to September 30. For example, Fiscal Year 2017 (FY 2017) starts October 1, 2016 and ends September 30, 2017. +A fiscal year may be broken down into quarters. For the federal government, these quarters are: + +- Q1: October - December +- Q2: January - March +- Q3: April - June +- Q4: July - September + +## Formula Grant + +An allocation made to states (or their subdivisions, which include county and local governments, among other entities) according to law. These grants are awarded for continuing activities that aren’t confined to a specific project — for example, Medicaid. + +**Official definition:** Allocations made to states (or their subdivisions) according to law or administrative regulation. These grants are awarded for continuing activities that aren’t confined to a specific project. + +## Funding Agency + +A Funding Agency pays for the majority of funds for an award out of its budget. Typically, the Funding Agency is the same as the Awarding Agency. In some cases, one agency will administer an award (Awarding Agency) and another agency will pay for it (Funding Agency). + +**Official definition:** Name and 3-digit CGAC agency code of the department or establishment of the Government that provided the preponderance of the funds for an award and/or individual transactions related to an award. + +## Funding Obligated + +The amount of money that an agency has promised to pay, usually because the agency has signed a contract, awarded a grant, or placed an order for goods or services. + +In the "Financial Systems Details" tab on an award summary page, this amount refers to the funding obligated in an agency's financial system. + +**Official definition:** The definition for this element appears in Section 20 of OMB Circular A-11 issued June 2015; a brief summary from A-11 appears below. + +Obligation means a binding agreement that will result in outlays, immediately or in the future. Budgetary resources must be available before obligations can be incurred legally. + +## Funding Office + +The office within an agency that pays the majority of funds for an award out of its budget. + +**Official definition:** Name and identifier of the level n organization that provided the preponderance of the funds obligated by this transaction. + +## Funding Opportunity Goals Text + +A brief summary of the intended outcomes associated with the notice of funding opportunity. + +## Funding Opportunity Number + +An alphanumeric identifier that a Federal agency assigns to its funding opportunity announcement as part of the Notice of Funding Opportunity posted on the OMB-designated government-wide web site (currently grants.gov) for finding and applying for Federal financial assistance. + +## Funding Sub-Agency + +A component of a larger department or agency that pays for the majority of funds for an award out of its budget. Also known as a sub-tier agency. For example, Bureau of Indian Affairs is a sub-agency of Department of Interior. + +**Official definition:** Name and identifier of the level 2 organization that provided the preponderance of the funds obligated by this transaction. + +## Government wide Acquisition Contract (GWAC) + +Government-Wide Acquisition Contract (GWAC) is a multi-agency contract. It offers Information Technology (IT) services to agencies across the government. It is an Indefinite Delivery Vehicle (IDV) for certain types of IT work: + +- Systems design +- Software engineering +- Information assurance +- Enterprise architecture + +Vendors compete for the initial contracts. Once selected, they are eligible to compete further for agency-specific tasks. + +## Governmentwide Spending Data Model (GSDM) + +The Governmentwide Spending Data Model (GSDM), formerly called the DATA Act Information Model Schema (DAIMS), is the authoritative source for the data elements that establish government-wide data standards for spending data and their subsequent publication for transparency. + +**Official definition:** The Governmentwide Spending Data Model (GSDM), formerly called the DATA Act Information Model Schema (DAIMS), was created as a result of the Digital Accountability and Transparency Act of 2014 (DATA Act). The GSDM is the authoritative source for the terms, definitions, formats and structures for hundreds of distinct data elements that establish government-wide data standards for spending data and their subsequent publication for transparency. + +The Office of Management and Budget (OMB) and Department of the Treasury (Treasury) collected public input and feedback from federal agencies and implemented an agile development methodology to create the DAIMS. The finalized DAIMS first published in April 2016. Since then, Treasury has periodically published updates to reflect the inclusion of legislation and policies that go beyond the DATA Act. + +In November 2023, DAIMS was rebranded as the GSDM to reflect the inclusion of new legislation and policies. The GSDM includes artifacts that provide technical guidance for federal agencies about what data to report to Treasury including the authoritative sources of the data elements and the submission format. The GSDM documents also provide data consumers with information and context to better understand the inherent complexity of the data. + +## Grant + +An award of financial assistance from a federal agency to a recipient to carry out a public project or service authorized by a United States law. Unlike loans, grants do not need to be repaid. Most grants are awarded to state and local governments. On this site, you’ll see reference to several types of grants, including block grants, formula grants, project grants, and cooperative agreements. + +**Official definition:** A federal financial assistance award making payment in cash or in kind for a specified purpose. The federal government is not expected to have substantial involvement with the state or local government or other recipient while the contemplated activity is being performed. The term “grant” is used broadly and may include a grant to nongovernmental recipients as well as one to a state or local government, while the term “grant-in-aid” is commonly used to refer only to a grant to a state or local government. (For a more detailed description, see the Federal Grant and Cooperative Agreement Act of 1977, 31 U.S.C. §§ 6301–6308.) The two major forms of federal grants-in-aid are block and categorical. + +## Grants and Fixed Charges + +This major object class includes grants, subsidies, and contributions to foreign countries; insurance claims; indemnities (for example, payments to veterans for death or disability, or to compensate for loss of property); interest and dividends; and refunds. + +**Official definition:** This major object class covers object classes 41.0 through 44.0. This includes: +41.0 Grants, subsidies, and +contributions +42.0 Insurance claims and +indemnities +43.0 Interest and dividends +44.0 Refunds + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Guaranteed / Insured Loans + +Loan guarantee means any guarantee, insurance, or other pledge with respect to the payment of all or a part of the principal or interest on any debt obligation of a non-Federal borrower to a non-Federal lender. The term does not include the insurance of deposits, shares, or other withdrawable accounts in financial institutions. + +## Highly Compensated Officer Name + +First Name: The first name of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +Middle Initial: The middle initial of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +Last Name: The last name of an individual identified as one of the five most highly compensated “Executives.” “Executive” means officers, managing partners, or any other employees in management positions. + +## Highly Compensated Officer Total Compensation + +The cash and noncash dollar value earned by the one of the five most highly compensated “Executives” during the awardee's preceding fiscal year and includes the following (for more information see 17 C.F.R. § 229.402(c)(2)): salary and bonuses, awards of stock, stock options, and stock appreciation rights, earnings for services under non-equity incentive plans, change in pension value, above-market earnings on deferred compensation which is not tax qualified, and other compensation. + +## Indefinite Delivery / Definite Quantity Contract + +An indefinite delivery contract (IDC) facilitates the delivery of supply and service orders during a set timeframe. This type of contract is awarded to one or more vendors. + +Definite Quantity Contracts, which are a type of IDC, provide for delivery of a definite quantity of supplies or services for a fixed period, with deliveries to be scheduled at designated locations upon order. + +## Indefinite Delivery / Indefinite Quantity (IDIQ) Contract + +An Indefinite Quantity Contract is a type of Indefinite Delivery Contract (IDC). Sometimes the government contracts to buy supplies or services from a vendor over a period of time. For instances that government does not know the exact quantity it will need, an Indefinite Quantity Contract sets a quantity range with a min and max. It does not specify an exact number. For services, this is often called a Task Order Contract. For supplies, this is often called a Delivery Order Contract. + +## Indefinite Delivery / Requirements Contract + +Requirements contracts are for the fulfillment of all purchase requirements of supplies or services for designated government activities during a specified contract period, with deliveries to be scheduled by placing orders with the contractor. + +## Indefinite Delivery Contract (IDC) + +Indefinite Delivery Contract (IDC) facilitates the delivery of supply and service orders during a set timeframe. This type of contract is awarded to one or more vendors. + +Types of IDC's Include: + +- Indefinite Delivery / Definite Quantity Contract +- Indefinite Delivery / Requirements Contract +- Indefinite Delivery / Indefinite Quantity (IDIQ) Contract + +## Indefinite Delivery Vehicle (IDV) + +Vehicle to facilitate the delivery of supply and service orders. IDV Types include: + +- Blanket Purchase Agreement (BPA) +- Basic Ordering Agreement (BOA) +- Government-Wide Acquisition Contract (GWAC) +- Multi-Agency Contract +- Indefinite Delivery Contract (IDC) +- Federal Supply Schedule (FSS) + +## Indirect Cost Federal Share Amount + +The total amount of any single Federal award action that is allocated, per the award recipient’s approved award budget, to indirect costs. + +## Insurance + +Financial assistance provided to assure reimbursement for losses sustained under specified conditions. Coverage may be provided directly by the Federal government or through private carriers and may or may not involve the payment of premiums. See Catalog for Federal Domestic Assistance (CFDA). + +## Labor Standards + +Indicates whether the transaction is subject to the Labor Standards. The clause for Labor Standards is 52.222-41 "Labor Standards" - that goes with the Service Contract Labor Standards (formerly Service Contract Act). + +## Latest Transaction Action Date + +The action date of the most recent Prime Award Transaction of a Prime Award Summary. Note that this date may be different from the Period of Performance End Date (Current or Potential). Because award obligations are tied to action dates, any search for spending data on USAspending will search by this data element rather than by Period of Performance dates. + +## Legal Entity Country Name and Code + +The Name and Code for the country in which the awardee or recipient is located, using the ISO 3166-1 Alpha-3 GENC Profile, and not the codes listed for those territories and possessions of the United States already identified as “states.” + +## Loan + +A federal award from the government that the borrower will eventually have to pay back. Direct loans are those made for a specific time period with a reasonable expectation of repayment; they may or may not require interest payments. Guaranteed loans require the federal government to pay the bank and take over the loan if the borrower defaults. + +## Loan Subsidy Cost + +When the government makes a direct loan or guarantees a loan, it expects the loan to be repaid. However, for any given loan program (e.g., student loans, small business loan guarantees) some individual loans are not repaid. Subsidy cost is the government’s way to estimate a loan’s likely cost to the government based on the size of the loan (i.e., its Face value), interest rate, the modeled risk of default in full or in part, and other factors. Subsidy cost is computed as a percentage of the loan value and does not include administrative costs. + +While the award amount for a grant or contract is the amount that the recipient gets, for a loan, the award amount is the subsidy cost. This is because the subsidy cost is the actual cost to the government (estimated). Loan Subsidy Cost has a direct budgetary impact and is factored into obligations and outlays when it is positive. Subsidy costs can be positive (indicating that the government is likely to lose money on the loan) or negative (indicating that the government is likely to make money on the loan). A positive Loan Subsidy Cost is usually smaller than the corresponding Face Value, but in certain edge cases it can be over 100% of the face value if the entire loan is written off and the government paid fees to a bank to issue the loan (which are also included in the subsidy cost). Administrative costs of running the loan or loan guarantee program itself are excluded from Loan Subsidy Cost calculation. + +**Official definition:** The estimated long-term cost to the Government of a direct loan or loan guarantee, or modification thereof, calculated on a net present value basis, excluding administrative costs. + +## Local Area Set Aside + +When awarding emergency response contracts during a major disaster or emergency declaration by the President, the government attempts to give preference to local firms. Preference may be given through a local area set-aside or an evaluation preference. + +**Official definition:** When awarding emergency response contracts during the term of a major disaster or emergency declaration by the President of the United States under the authority of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. 5121, et seq.), preference shall be given, to the extent feasible and practicable, to local firms. Preference may be given through a local area set-aside or an evaluation preference. Note: When the value for the data element 'Multiple or Single Award IDV' is 'Single' on the Referenced IDV, the value for 'Local Area Set Aside' is propagated from the BPA. When the value is 'Multiple' user input is required. + +## Main Account Code + +This is a 4-digit number that is part of a Treasury Account Symbol (TAS) and Identifies the TAS type and purpose. It cannot be blank. + +**Official definition:** The main account code identifies the account in statute. + +## Materials, Supplies, Articles & Equip + +Indicates whether the transaction is subject to the Materials, Supplies, Articles, & Equip. The clause is 52.222-20 "Contracts for Materials, Supplies, Articles, and Equipment Exceeding $15,000" - that goes with Contracts for Materials, Supplies, Articles, and Equipment Exceeding $15,000 (formerly Walsh-Healey). + +## Modification Number + +The identifier of an action being reported that indicates the specific subsequent change to the initial award. + +## Multi-Agency Contract (MAC) + +A Multi-Agency Contract (MAC) is a task-order or delivery-order contract established by one agency for use by government agencies to obtain supplies and services. + +## Multiple Award Schedule (MAS) + +A listing of contractors that have been awarded a contract by GSA that can be used by all federal agencies. This is also known as a Federal Supply Schedule (FSS). + +## Multiple Recipients + +A recipient name of "MULTIPLE RECIPIENTS" indicates that the financial assistance award has been aggregated to protect the Personally Identifiable Information (PII) of a collection of individuals. Agencies are prohibited from publishing PII on USAspending. Aggregating involves grouping awards to individuals (typically from the same program and time period) by county (for domestic awards), state (for domestic awards), or country (for foreign awards). These records omit location information that would normally be present (street address and the last 4 digits of the ZIP code) and replace the recipient name with “MULTIPLE RECIPIENTS.” The award summary pages for these records specify the level of aggregation. + +## NAICS + +NAICS stands for the North American Industrial Classification System. This 6-digit code tells you what industry the work falls into. Each contract record has a NAICS code. That means you can look up how much money the U.S. government spent in a specific industry. + +The list of industries and codes is updated every 5 years. + +**Official definition:** The identifier and title that represents the North American Industrial Classification System Code assigned to the solicitation and resulting award identifying the industry in which the contract requirements are normally performed + +## National Interest Action (NIA) + +The National Interest Action (NIA) code categorizes federal contracts that are related to emergency responses or other nationally significant events. + +**Official definition:** The National Interest Action values are used to categorize procurement actions related to emergency contingency responses or other nationally significant events. The length of the value is no more than 4 characters. A new NIA value was created to address the COVID-19 pandemic and this value is valid for actions signed between 3/13/2020 and 9/30/2020. + +Below are examples of NIA values: + - H19M – Hurricane Michael 2019 + - H19D – Hurricane Dorian 2019 + - P20C – COVID-19 2020 + +Note that the Disaster Emergency Fund Code (DEFC) is also used to track COVID-19 spending. However, it is not limited to contracts and is necessarily tied to COVID-19 supplemental appropriations. Thus, awards with the COVID-19 NIA value may not have a COVID-19 DEFC value, and vice versa. + +## Non-Federal Funding Amount + +The amount of the award funded by non-Federal source(s), in dollars. Program Income (as defined in 2 CFR § 200.1) is not included until such time that Program Income is generated and credited to the agreement. + +Award obligation and award outlay amounts (from Files C, D1, and D2) only count dollars spent from federal funding, not any dollars spent from non-federal funding. + +## Object Class + +Object class is one way to classify financial data in the federal budget. An object class groups obligations by the types of items or services purchased by the federal government. Examples: "Personnel Compensation" and "Equipment" + +**Official definition:** Categories in a classification system that presents obligations by the items or services purchased by the Federal Government. Each specific object class is defined in OMB Circular A-11 § 83.6. + +(defined in OMB Circular A-11) + +## Obligation + +When awarding funding, the U.S. government enters a binding agreement called an obligation. The government promises to spend the money, either immediately or in the future. An agency incurs an obligation, for example, when it places an order, signs a contract, awards a grant, purchases a service, or takes other actions that require it to make a payment. + +Loan Subsidy Cost has a direct budgetary impact and is factored into obligations and outlays when it is positive. + +**Official definition:** Obligation means a legally binding agreement that will result in outlays, immediately or in the future. When you place an order, sign a contract, award a grant, purchase a service, or take other actions that require the Government to make payments to the public or from one Government account to another, you incur an obligation. It is a violation of the Antideficiency Act (31 U.S.C. § 1341(a)) to involve the Federal Government in a contract or obligation for payment of money before an appropriation is made, unless authorized by law. This means you cannot incur obligations in a vacuum; you incur an obligation against budget authority in a Treasury account that belongs to your agency. It is a violation of the Antideficiency Act to incur an obligation in an amount greater than the amount available in the Treasury account that is available. This means that the account must have budget authority sufficient to cover the total of such obligations at the time the obligation is incurred. In addition, the obligation you incur must conform to other applicable provisions of law, and you must be able to support the amounts reported by the documentary evidence required by 31 U.S.C. § 1501. Moreover, you are required to maintain certifications and records showing that the amounts have been obligated (31 U.S.C. § 1108). The following subsections provide additional guidance on when to record obligations for the different types of goods and services or the amount. + + + +Additional detail is provided in Circular A‐11. + +## Ordering Period End Date + +For procurement, the date on which, for the award referred to by the action being reported, no additional orders referring to it may be placed. This date applies only to procurement indefinite delivery vehicles (such as indefinite delivery contracts or blanket purchase agreements). Administrative actions related to this award may continue to occur after this date. The period of performance end dates for procurement orders issued under the indefinite delivery vehicle may extend beyond this date. + +## Other Budgetary Resources + +A subset of budget authority. Most spending by agencies is authorized by appropriation laws; a small amount may come from money not spent in the previous year. The rest is authorized in other ways and grouped together on USAspending.gov as Other Budgetary Resources. + +**Official definition:** New borrowing authority, contract authority, and spending authority from offsetting collections provided by Congress in an appropriations act or other legislation, or unobligated balances of budgetary resources made available in previous legislation, to incur obligations and to make outlays. + +(defined in OMB Circular A-11) + +## Other Financial Assistance + +Financial assistance from the Federal Government that is not described by any of the previously-defined assistance types. + +## Other Object Class + +This major object class includes other miscellaneous charges. + +**Official definition:** This major object class covers object classes 91.0 through 99.5. This includes: +91.0 Unvouchered +92.0 Undistributed +94.0 Financial transfers +99.0 Subtotal, obligations +99.5 Adjustment for rounding + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Other Transaction (OT) Indefinite Delivery Vehicle (IDV) + +An Other Transaction (OT) Indefinite Delivery Vehicle is a transaction other than a procurement contract, grant, or cooperative agreement. Since this transaction is defined in the negative, it could take unlimited potential forms. This term is often used to refer to transactions designed to: + +- Support research & development for homeland security. +- Advance the development, testing, and deployment of critical homeland security technologies. +- Speed up prototyping and deployment of technologies addressing homeland security vulnerabilities. + +The Department of Homeland Security (DHS) often splits its use of OT's for Research and Prototype Projects. + +## Outlay + +An outlay occurs when federal money is actually paid out, not just promised to be paid ("obligated"). + +**Official definition:** Payments made to liquidate an obligation (other than the repayment of debt principal or other disbursements that are “means of financing” transactions). Outlays generally are equal to cash disbursements but also are recorded for cash-equivalent transactions, such as the issuance of debentures to pay insurance claims, and in a few cases are recorded on an accrual basis such as interest on public issues of the public debt. Outlays are the measure of Government spending. + +(defined in OMB Circular A-11) + +## Parent Award Identification (ID) Number + +The identifier of the procurement award under which the specific award is issued, such as a Federal Supply Schedule. This data element currently applies to procurement actions only. + +## Parent DUNS + +The unique identification number for the ultimate parent of an awardee or recipient. Currently the identifier is the 9-digit number maintained by Dun & Bradstreet as the global parent DUNS® number. + +## Period of Performance Current End Date + +The date that the award ends, as agreed upon by the parties involved without exercising any pre-determined extension options. Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than this date. + +**Official definition:** For procurement awards: The contract completion date based on the schedule in the contract. For an initial award, this is the scheduled completion date for the base contract and for any options exercised at time of award. For modifications that exercise options or that shorten (such as termination) or extend the contract period of performance, this is the revised scheduled completion date for the base contract including exercised options. If the award is solely for the purchase of supplies to be delivered, the completion date should correspond to the latest delivery date on the base contract and any exercised options. The completion date does not change to reflect a closeout date. + +For grants and cooperative agreements: The Period of Performance is defined in the CFR 200 as the total estimated time interval between the start of an initial Federal award and the planned end date, which may include one or more funded portions, or budget periods. If the end date is revised due to an extension, termination, lack of available funds, or other reason, the current end date will be amended. + +For all other financial assistance awards: The current date on which, for the award referred to by the action being reported, awardee effort completes or the award is otherwise ended. Administrative actions related to this award may continue to occur after this date. + +Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than Period of Performance Current End Date. + +## Period of Performance Potential End Date + +The date that the award ends, as agreed upon by the parties involved after exercising any pre-determined extension options. Note that the latest transaction for the award (known as the Latest Transaction Action Date) may be different than this date. + +Administrative actions related to this award may continue to occur after the Period of Performance Potential End Date. + +The Period of Performance Potential End Date does not apply to Contract Indefinite Delivery Vehicles under which Definitive Contracts may be awarded. + +## Period of Performance Start Date + +The date that the award begins, as agreed upon by the parties involved. Note that the first transaction for the award (known as the Base Transaction Action Date) may be different than this date. + +**Official definition:** For procurement awards: Per the FPDS data dictionary, the date that the parties agree will be the starting date for the contract's requirements. This is the period of performance start date for the entire contract period, this date does not reflect period of performance per modification, but rather the start of the entire contract period of performance. This data element does NOT correspond to FAR 43.101 or 52.243 and should not be mapped to those fields in your contract writing systems. + +For grants and cooperative agreements: The Period of Performance is defined in the 2 CFR 200 as the total estimated time interval between the start of an initial Federal award and the planned end date, which may include one or more funded portions, or budget periods. + +For all other financial assistance awards: The date on which, for the award referred to by the action being reported, awardee effort begins or the award is otherwise effective. + +Note that the first transaction for the award (known as the Base Transaction Action Date) may be different than the Period of Performance Start Date. + +## Personnel Compensation and Benefits + +This major object class includes employee compensation, including salaries, wages, and health benefits, for federal employees. Personnel compensation and benefits apply to full-time and part-time employees, along with military personnel. + +**Official definition:** This major object class consists of object classes 11, 12, and 13. This includes: +11 Personnel compensation +11.1 Full-time permanent +11.3 Other than full-time +permanent +11.5 Other personnel +compensation +11.6 Military personnel - +basic allowance for +housing +11.7 Military personnel +11.8 Special personal services +payments +11.9 Total personnel +compensation +12 Personnel benefits +12.1 Civilian personnel +benefits +12.2 Military personnel +benefits +13.0 Benefits for former +personnel + +Each specific object class is defined in OMB Circular A-11 Section 83.6. + +## Potential Award Amount + +The total amount that could be obligated on a contract. This total includes the base plus options amount. For example, if a recipient is awarded $10M on a base contract with 3 option years at $1M each, the potential award amount is $13M. + +**Official definition:** For procurement, the total amount that could be obligated on a contract, if the base and all options are exercised. + +## Primary Place of Performance + +The principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** The address where the predominant performance of the award will be accomplished. The address is made up of four components: City, State Code, and ZIP+4 or Postal Code. + +## Primary Place of Performance Congressional District + +The congressional district where the principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** U.S. congressional district where the predominant performance of the award will be accomplished. This data element will be derived from the Primary Place of Performance Address. + +## Primary Place of Performance Country + +The country where the principal place of business, where the majority of the work is performed. For example, in a manufacturing contract, this would be the main plant where items are produced. + +**Official definition:** Country code where the predominant performance of the award will be accomplished. + +## Prime Award + +A prime award is an agreement that the government makes with a non-federal entity for the purpose of carrying out a federal program. The entities receiving the prime award are known as prime recipients. + +The term “prime award” can be used as a generic term to describe either transactions or prime award summaries. + +**Official definition:** A Prime Award is a federal award that is either: +(1) Federal financial assistance that a non-Federal entity receives directly from a Federal awarding agency; or +(2) The cost-reimbursement contract under the Federal Acquisition Regulations that a non-Federal entity receives directly from a Federal awarding agency. +(Adapted from 2 CFR §200.38) + +## Prime Award Summary + +A prime award summary includes all related prime award transactions that share the same prime award unique key. Award Profile pages on USAspending.gov allow users to browse individual prime award summaries, including the list of transactions that constitute the prime award summary, the list of sub-awards funded by the prime award summary, and the list of federal accounts which have funded the prime award summary. + +Generally speaking, information from the most recent prime award transaction is applied to the summary-level information in the prime award summary. For example, the award’s recipient name, awarding agency, and period of performance at the summary level is drawn from the latest transaction of that award. + +## Prime Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, or foreign) that receives funding directly from the U.S. government. They receive this funding through an agreement called a prime award. For example, if the Dept. of Transporation is building a bridge, they can award Bridge Company A the contract to carry out the construction. Bridge Company A would be the prime recipient. + +**Official definition:** A non-Federal entity that receives a Federal award directly from a Federal awarding agency to carry out an activity under a Federal program. + +## Procurement Instrument Identifier (PIID) + +A unique identifier assigned to a federal contract, purchase order, basic ordering agreement, basic agreement, and blanket purchase agreement. It is used to track the contract and any modifications or transactions related to it. + +**Official definition:** The unique identifier of the specific award being reported. + +[Read more in the Federal Acquisition Regulation](https://www.acquisition.gov/far/html/Subpart%204_16.html). + +## Product or Service Code (PSC) + +A Product or Service Code (PSC) is a 4-character code that identifies the type of product, service, or research & development (R&D) purchased. While NAICS codes identify the industry most relevant to a contract, PSCs tell you what the contract is specifically purchasing. For example, a contract’s NAICS code might point to the “Industrial Building Construction” industry, while that same contract’s PSC points to “Construct Hospitals and Infirmaries.” There are nearly three times as many PSCs (over 2,900) as there are NAICS codes (just over 1000), which in many cases allows a more granular PSC designation than NAICS code designation for a given contract. + +All PSC are 4 characters long, but there is an embedded hierarchy in the codes. + +- **R&D**: begin with ‘A’ (indicating R&D), followed by a second letter, followed by a number, followed by a number (four levels of hierarchy). Example: AA11. + +- **Services**: begin with ‘B’ to ‘Z’ (indicating the subcategory of Service), followed by a number, followed by two letters (four levels of hierarchy if you include the “Service” designation). Example: C1AA + +- **Products**: begin with two numbers (indicating the subcategory of Product), followed by two more numbers (three levels of hierarchy if you include the “Product” designation). Example: 1005 + +**Official definition:** The code that best identifies the product or service procured. Codes are defined in the Product and Service Codes Manual. + +## Program Activity + +A program activity is a category within an appropriation account. A program activity is a specific activity or project, as listed in the program and financing schedules of the annual budget of the U.S. government. + +**Official definition:** A specific activity or project as listed in the program and financing schedules of the annual budget of the United States Government. + +According to OMB Circular A-11, The activities should: +- Clearly indicate the services to be performed or the programs to be conducted; +- Finance no more than one strategic goal or objective; +- Distinguish investment, developmental, grant and subsidy, and operating programs; and +- Relate to administrative control and operation of the agency. + +## Program, System, and Equipment Code + +A system-generated Department of Defense (DOD) code, also known as the Acquisition Program (AP) Code. This code identifies the DOD program, weapons system, or equipment being acquired. It can be categorized as a Major Defense Acquisition Program (MDAP) or a Major Automated Information System (MAIS). + +**Official definition:** Two codes that together identify the program and weapons system or equipment purchased by a DOD agency. The first character is a number 1-4 that identifies the DOD component. The last 3 characters identify that component's program, system, or equipment. + +[Read more about this code](https://www.fpds.gov/help/SystemEquipment.htm) on the General Services Administration website. + +## Project Grant + +Funding of specific projects for a fixed amount of time. Some examples include fellowships, scholarships, research grants, survey grants, and construction grants. + +**Official definition:** Project grants provide federal funding for fixed or known periods for specific projects or the delivery of specific services or products. + +## Purchase Order + +A Purchase Order is an offer by the government established to buy supplies or services, including construction and research and development, upon specified terms and conditions, using simplified acquisition procedures. + +## Reason for Modification + +Provides information on the type of change made to an award. + +**Official definition:** Description (and corresponding code) that provides information on any changes made to the Federal prime award. There are typically multiple actions for each award. + +(Note: This definition encompasses current data elements ‘Type of Action’ for financial assistance and ‘Reason for Modification’ for procurement) + +## Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, federal, or foreign), that receives funding from the U.S. government. + +## Recipient Congressional District + +The congressional district in which the recipient is located. + +**Official definition:** The congressional district in which the awardee or recipient is located. This is not a required data element for non-U.S. addresses. + +## Recipient Location + +Legal business address of the recipient. + +**Official definition:** The awardee or recipient’s legal business address where the office represented by the Unique Entity Identifier (as registered in the System for Award Management) is located. In most cases, this should match what the entity has filed with the State in its organizational documents, if required. The address is made up of five components: Address Lines 1 and 2, City, State Code, and ZIP+4 or Postal Code. + +## Recipient Name + +A recipient is a company, organization, individual, or government entity (i.e., state, local, tribal, federal, or foreign), that received funding by the U.S. government. The recipient name is the same as what's registered in the System for Award Management (SAM.gov). This is usually the official name of the business. For individuals, the term 'Multiple Recipients' is used as the Recipient Name to protect individuals' privacy. + +**Official definition:** The name of the awardee or recipient that relates to the unique identifier. For U.S. based companies, this name is what the business ordinarily files in formation documents with individual states (when required). + +## Recipient/Business Types + +Recipient/Business types are socio-economic and other organizational/business characteristics that are used to categorize federal contractors and other funding recipients. There are many different recipient/business types, and they span for-profit businesses, non-profits, government entities, individuals, and foreign entities. Some examples are: + +- Historically Black College or University +- Veteran-Owned Business +- Historically Underutilized Business Zone (HUBZone) Firm +- Sole Proprietorship +- Foundation + +You can search and filter on all recipient types on this site. + +**Official definition:** A collection of indicators of different types of recipients based on socio-economic status and organization / business areas. + +## Record Type + +Code indicating whether an action is an Aggregate Record (Record Type = 1), a Non-aggregate Record (Record Type = 2), or a Non-Aggregate Record to an Individual Recipient with Redacted Personally Identifiable Information (Record Type = 3). + +## Redacted Due To PII + +A recipient name of "REDACTED DUE TO PII" indicates that the associated financial assistance award was issued to an individual whose name and other Personally Identifiable Information (PII) were redacted, as required by law. Along with masking the individual’s name with “REDACTED DUE TO PII,” these records omit location information that would otherwise be present (street address and the last 4 digits of the ZIP code). + +## Set Aside Type + +A tool used to award contracts to specific types of businesses. Most set asides reserve contracts for small businesses. Others are more specific, to support small businesses with specific designations, such as veteran owned business or small disadvantaged business types. + +**Official definition:** The designator for type of set aside determined for the contract action. + +## Simplified Acquisition Procedures (SAP) + +For certain types of government purchases between $3,000 and $150,000. These purchases may require less approval and less documentation. + +## Solicitation + +When an agency needs work done, it can ask for information or bids on the work. These requests are called solicitations. They often come as a RFI (Request for Information) or RFP (Request for Proposal). + +## Spending + +On this site, the term spending could either describe obligations (amount awarded) or outlays (amount paid out). + +## Sub Account Code + +Sub Account Code (SUB) is a component of the TAS that identifies a Treasury-defined subdivision of a Federal Account (AID + MAIN). Most Federal Accounts do not have subdivisions. 000 is the default SUB; if 000 is the only SUB under a given Federal Account, it has not been subdivided + +**Official definition:** This is a component of the TAS. Identifies a Treasury-defined subdivision of the main account. This field cannot be blank. Sub Account 000 indicates the Parent account. + +## Sub-Award + +A sub-award is an agreement that a prime recipient makes with another entity to perform a portion of their award. On our website, these recipients are known as sub-recipients. Sub-awards might also be referred to as a sub-contract or a sub-grant. Sub-award amounts are funded by prime award obligations and outlays. In theory, the total value of all sub-award amounts for any given prime award is a subset of the Current Award Amount for that prime award; sub-award amounts generally should not exceed the Current Award Amount for their associated prime award. To avoid double-counting the overall value of a prime award, do not sum up sub-award amounts and prime award obligations or outlays. + +**Official definition:** An award provided by a pass-through entity to a subrecipient for the subrecipient to carry out part of a federal award received by the pass-through entity. It does not include payments to a contractor or payments to an individual that is a beneficiary of a federal program. A subaward may be provided through any form of legal agreement, including an agreement that the pass-through entity considers a contract. (2CFR) + +## Sub-Recipient + +A company, organization, individual, or government entity (i.e., state, local, tribal, or foreign) that receives funding from another recipient of federal funds (a prime recipient), rather than directly from the U.S. government. The sub-recipient may be a sub-contractor or a sub-grantee. For example, the Dept. of Transporation awards Bridge Company A a bridge construction contract. Bridge Company A needs Bridge Company B to supply the steel, so Bridge Company A awards Bridge Company B a sub-award. Bridge Company B is the sub-contractor. On the grants side, University A receives an R&D grant from the National Science Foundation. University A needs University B to perform the initial step in the research, so University A awards University B a sub-award. University B is the sub-grantee. + +**Official definition:** A non-Federal entity that receives a sub-award from a pass-through entity to carry out part of a federal program; but does not include an individual that is the beneficiary of such program. (grants.gov) + +## Submission Period + +The submission period shows when federal agencies submit their financial data. It is displayed as a fiscal year (e.g., “FY 2020” or “FY20” for fiscal year 2020, covering October 2019 through September 2020) followed by a month (e.g., “P01” for October, which is the first month of the fiscal year) or quarter (e.g., “Q1” for the first quarter of the fiscal year, covering October through December). For example, “FY19 P10” indicates a submission whose data covers the period of July 2019. + +Starting with the June 2020 reporting period, most federal agencies began submitting their account data (Files A, B, and C) to the Treasury DATA Act Broker on a monthly basis rather than on the previous quarterly schedule. As of October 2021 (FY22 Q1), all agencies are required to report on a monthly basis. More information about the agency account data reporting policy is found in OMB’s Memorandum M-20-21 (Appendix A, Section III). + +## Task Order Contract + +An Indefinite Quantity Contract for services (not supplies) is sometimes referred to as a Task Order Contract. With this type of contract, the government promises to buy services over a period of time from a vendor. Instead of an exact amount, it sets a range with a minimum and maximum. + +## Transaction + +A transaction can be the initial contract, grant, loan, or insurance award or any amendment or modification to that award. + +## Transaction Description + +A brief description of the purpose of the transaction. + +## Treasury Account Symbol (TAS) + +Treasury and OMB assign a code to each appropriation, receipt, or fund account. This code is similar to a bank account number. It helps identify financial transactions in the federal government. It also aids in reporting accuracy. TAS are sometimes referred as ‘program source’ in legislation. On this website, we group each set of Treasury Accounts that share an Agency Identifier and Main Account Code into a "Federal Account". + +Seven components make up the TAS: + +- Allocation Transfer Agency Identifier (ex. 089) +- Agency Identifier (ex. 020) +- Beginning Period of Availability (ex. 2017) +- Ending Period of Availability (ex. 2018) +- Availability Type Code (used if there are not specific beginning/ending years) (ex. X) +- Main Account Code (ex. 0114) +- Sub Account Code (ex. 000) + +Example TAS: + +- 089-020-2017/2018-0114-000 +- 089-020-2017/2017-0114-000 +- 089-020-X-0114-000 + +**Official definition:** Treasury Account Symbol: The account identification codes assigned by the Department of the Treasury to individual appropriation, receipt, or other fund accounts. All financial transactions of the Federal Government are classified by TAS for reporting to the Department of the Treasury and the Office of Management and Budget. + +(defined in OMB Circular A-11) + +## Ultimate Parent Legal Entity Name + +The name of the ultimate parent of the awardee or recipient. + +## Unique Entity Identifier (UEI) + +The Unique Entity Identifier (UEI) for an awardee or recipient is an alphanumeric code created in the System for Award Management (SAM.gov) that is used to uniquely identify specific commercial, nonprofit, or business entities registered to do business with the federal government. + +## Unlinked Award + +There are two distinct datasets transmitted to USAspending for agency awards—File C and Files D. File C is submitted and published on the site on a monthly or quarterly basis from audited agency financial systems. File D1 (procurement) and File D2 (financial assistance) data is generated from award reporting data submitted by agencies to other systems and updated on USAspending as frequently as daily. Because these data originate from different communities and systems within agencies that are subject to different policies and reporting requirements, there are sometimes gaps between the awards captured in each dataset. + +Unlinked awards lack a shared award ID that allows a match between financial system data and award reporting data. As a result, such awards only show up in some parts of the site and are missing their full context. For example, awards found in File C but not in File D lack recipient and CFDA Program information and thus, will not have an Award Summary page. + +## Unobligated Balance + +The amount of money out of an account that has yet to be awarded or obligated (promised to be spent). + +**Official definition:** Unobligated balance means the cumulative amount of budget authority that remains available for obligation under law in unexpired accounts at a point in time. The term “expired balances available for adjustment only” refers to unobligated amounts in expired accounts. + + + +Additional detail is provided in Circular A‐11. + +## Unreported Data + +There are various reasons financial or award data is not reported by agencies or otherwise available to USAspending.gov at a given time. These include, but are not limited to, timing of data availability, or sensitive data that is not subject to submission. Where possible, USAspending.gov advises readers that other information exists that cannot be detailed. + +## URI + +URI stands for Unique Record Identifier. A URI is an agency-defined identifier that is unique for every financial assistance action reported by that agency. USAspending.gov uses URI as the Award ID for aggregate records. diff --git a/examples/sandbox/extensions/daytona/usaspending_text2sql/schema/overview.md b/examples/sandbox/extensions/daytona/usaspending_text2sql/schema/overview.md new file mode 100644 index 0000000..1f66ac9 --- /dev/null +++ b/examples/sandbox/extensions/daytona/usaspending_text2sql/schema/overview.md @@ -0,0 +1,60 @@ +## Database: usaspending.db + +NASA federal spending data from USAspending.gov.

The portable snapshot is preserved so workspace files carry over. + +**Forking** pauses the source workflow, snapshots its state and conversation history, and starts a new child workflow on the chosen backend.

The scenario is intentionally synthetic and generic: a patient asks a billing or coverage question, the workflow checks local records, inspects policy documents in an isolated sandbox workspace, writes support artifacts, and optionally routes one ambiguous case to a human reviewer. + +## What this example demonstrates + +- **Standard agent orchestration** with a top-level support orchestrator and a benefits subagent. +- **Sandbox agents** with a mounted workspace, shell commands, a generated output folder, and runtime-selected sandbox config. +- **Sandbox capabilities** including `Shell`, `Filesystem`, and lazy-loaded `Skills`. +- **Human-in-the-loop approvals** using an approval-gated queue-routing tool. +- **Persistent memory** with `SQLiteSession`, shared across scenario runs. +- **Structured outputs** for each specialist agent and the final case resolution. +- **Tracing** so you can inspect every model call and tool call in the OpenAI trace viewer. +- **CLI-first workflow** that can be run scenario by scenario from the repository checkout. + +## Architecture + +The workflow has two execution modes working together: + +1. A **standard orchestrator agent** runs in the normal Agents SDK loop, calls the benefits subagent first, then calls a sandbox agent tool, and decides whether to request a human handoff. +2. A **sandbox policy agent** runs behind `agents.sandbox`, reads the mounted case files and policy documents, uses shell commands plus a lazily loaded skill, writes markdown artifacts into `output/`, and returns a structured policy summary. + +The local fixture data lives in `data/scenarios/*.json` and `data/fixtures/*.json`. The sandbox policy library lives in `policies/*.md`. Generated artifacts are copied to `.cache/healthcare_support/output//`. + +## Scenarios + +The built-in scenarios increase in complexity: + +- `eligibility_verification_basic` checks a straightforward benefits question. +- `referral_status_check` adds a referral lookup. +- `blue_cross_pt_benefits` shows a follow-up turn that benefits from the shared SQLite memory. +- `prior_auth_confusion_ct` focuses on prior-authorization and intake-routing confusion. +- `billing_coverage_clarification` combines benefits lookup with sandbox policy search and document generation. +- `messy_ambiguous_knee_case` triggers the human approval flow before queueing a handoff. + +## Run the CLI demo + +From the repository root: + +```bash +uv run python

When working in a subdirectory of CWD, or a directory outside the CWD, check for any AGENTS.md files that may be applicable. + +## Responsiveness + +### Preamble messages + +Before making tool calls, send a brief preamble to the user explaining what you’re about to do. When sending preamble messages, follow these principles and examples: + +- **Logically group related actions**: if you’re about to run several related commands, describe them together in one preamble rather than sending a separate note for each. +- **Keep it concise**: be no more than 1-2 sentences, focused on immediate, tangible next steps. (8–12 words for quick updates). +- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what’s been done so far and create a sense of momentum and clarity for the user to understand your next actions. +- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging. +- **Exception**: Avoid adding a preamble for every trivial read (e.g., `cat` a single file) unless it’s part of a larger grouped action. + +**Examples:** + +- “I’ve explored the workspace; now checking the relevant files.” +- “Next, I’ll update the config and verify the related behavior.” +- “I’m about to set up the commands and helper steps.” +- “Ok cool, so I’ve wrapped my head around the workspace.

Please keep going until the query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved.

Do NOT guess or make up an answer. + +You MUST adhere to the following criteria when solving queries: + +- Working on the repo(s) in the current environment is allowed, even if they are proprietary. +- Analyzing code for vulnerabilities is allowed. +- Showing user code and tool call details is allowed. +- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`): {"command":["apply_patch","*** Begin Patch\\n*** Update File: path/to/file.py\\n@@ def example():\\n- pass\\n+ return 123\\n*** End Patch"]} + +If completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines: + +- Fix the problem at the root cause rather than applying surface-level patches, when possible. +- Avoid unneeded complexity in your solution. +- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) +- Update documentation as necessary. +- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task. +- Use `git log` and `git blame` to search the history of the codebase if additional context is required. +- NEVER add copyright or license headers unless specifically requested. +- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc. +- Do not `git commit` your changes or create new git branches unless explicitly requested. +- Do not add inline comments within code unless explicitly requested. +- Do not use one-letter variable names unless explicitly requested. +- NEVER output inline citations like "【F:README.md†L5-L14】" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor. + +## Validating your work + +If the codebase has tests or the ability to build or run, consider using them to verify that your work is complete. + +When testing, your philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests. + +Similarly, once you're confident in correctness, you can suggest or use formatting commands to ensure that your code is well formatted. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one. + +For all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) + +Be mindful of whether to run validation commands proactively. In the absence of behavioral guidance: + +- When running in non-interactive approval modes like **never** or **on-failure**, proactively run tests, lint and do whatever you need to ensure you've completed the task. +- When working in interactive approval modes like **untrusted**, or **on-request**, hold off on running tests or lint commands until the user is ready for you to finalize your output, because these commands take time to run and slow down iteration. Instead suggest what you want to do next, and let the user confirm first. +- When working on test-related tasks, such as adding tests, fixing tests, or reproducing a bug to verify behavior, you may proactively run tests regardless of approval mode. Use your judgement to decide whether this is a test-related task. + +## Ambition vs. precision + +For tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation. + +If you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature. + +You should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified. + +## Sharing progress updates + +For especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next. + +Before doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why. + +The messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along. + +## Presenting your work and final message + +Your final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user’s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges. + +You can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation. + +The user is working on the same computer as you, and has access to your work. As such there's no need to show the full contents of large files you have already written unless the user explicitly asks for them. Similarly, if you've created or modified files using `apply_patch`, there's no need to tell users to "save the file" or "copy the code into a file"—just reference the file path. + +If there's something that you think you could help with as a logical next step, concisely ask the user if they want you to do so. Good examples of this are running tests, committing changes, or building out the next logical component. If there’s something that you couldn't do (even with approval) but that the user might want to do (such as verifying changes by running the app), include those instructions succinctly. + +Brevity is very important as a default. You should be very concise (i.e. no more than 10 lines), but can relax this requirement for tasks where additional detail and comprehensiveness is important for the user's understanding. + +### Final answer structure and style guidelines + +You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value. + +**Section Headers** + +- Use only when they improve clarity — they are not mandatory for every answer. +- Choose descriptive names that fit the content +- Keep headers short (1–3 words) and in `**Title Case**`. Always start headers with `**` and end with `**` +- Leave no blank line before the first bullet under a header. +- Section headers should only be used where they genuinely improve scanability; avoid fragmenting the answer. + +**Bullets** + +- Use `-` followed by a space for every bullet. +- Merge related points when possible; avoid a bullet for every trivial detail. +- Keep bullets to one line unless breaking for clarity is unavoidable. +- Group into short lists (4–6 bullets) ordered by importance. +- Use consistent keyword phrasing and formatting across sections. + +**Monospace** + +- Wrap all commands, file paths, env vars, and code identifiers in backticks (`` `...` ``). +- Apply to inline examples and to bullet keywords if the keyword itself is a literal file/command. +- Never mix monospace and bold markers; choose one based on whether it’s a keyword (`**`) or inline code/path (`` ` ``). + +**File References** +When referencing files in your response, make sure to include the relevant start line and always follow the below rules: + * Use inline code to make file paths clickable. + * Each reference should have a stand alone path. Even if it's the same file. + * Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix. + * Line/column (1‑based, optional): :line[:column] or #Lline[Ccolumn] (column defaults to 1). + * Do not use URIs like file://, vscode://, or https://. + * Do not provide range of lines + * Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\workspace\project\main.rs:12:5 + +**Structure** + +- Place related bullets together; don’t mix unrelated concepts in the same section. +- Order sections from general → specific → supporting info. +- For subsections (e.g., “Binaries” under “Rust Workspace”), introduce with a bolded keyword bullet, then list items under it. +- Match structure to complexity: + - Multi-part or detailed results → use clear headers and grouped bullets. + - Simple results → minimal headers, possibly just a short list or paragraph. + +**Tone** + +- Keep the voice collaborative and natural, like a helpful teammate handing off work. +- Be concise and factual — no filler or conversational commentary and avoid unnecessary repetition +- Use present tense and active voice (e.g., “Runs tests” not “This will run tests”). +- Keep descriptions self-contained; don’t refer to “above” or “below”. +- Use parallel structure in lists for consistency. + +**Don’t** + +- Don’t use literal words “bold” or “monospace” in the content. +- Don’t nest bullets or create deep hierarchies. +- Don’t output ANSI escape codes directly — the CLI renderer applies them. +- Don’t cram unrelated keywords into a single bullet; split for clarity. +- Don’t let keyword lists run long — wrap or reformat for scanability. + +Generally, ensure your final answers adapt their shape and depth to the request. For example, answers to file or task explanations should have a precise, structured explanation with concrete references that answer the question directly. For tasks with a simple implementation, lead with the outcome and supplement only with what’s needed for clarity. Larger changes can be presented as a logical walkthrough of your approach, grouping related steps, explaining rationale where it adds value, and highlighting next actions to accelerate the user. Your answers should provide the right level of detail while being easily scannable. + +For casual greetings, acknowledgements, or other one-off conversational messages that are not delivering substantive information or structured results, respond naturally without section headers or bullet formatting. + +# Tool Guidelines + +## Shell commands + +When using the shell, you must adhere to the following guidelines: + +- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.) +- Do not use python scripts to attempt to output larger chunks of a file. diff --git a/src/agents/sandbox/manifest.py

If it is likely to matter again + in a recurring workflow, it belongs here. +- When deciding whether to include a preference, ask whether omitting it would make the next + agent more likely to need extra user steering. +- Keep epistemic status honest when the evidence is inferred rather than explicit. + +## General Tips + +Include information useful for almost every run, especially learnings that help the agent +self-improve over time. +Prefer durable, actionable guidance over one-off context. Use bullet points. Prefer +brief descriptions over long ones. + +For example, include (when known): + +- Collaboration preferences: tone/structure the user likes, what “good” looks like, what to avoid. +- Workflow and environment: runtime conventions, common commands/scripts, recurring setup steps. +- Decision heuristics: rules of thumb that improved outcomes (e.g. when to consult + memory, when to stop searching and try a different approach). +- Tooling habits: effective tool-call order, good search keywords, how to minimize + churn, how to verify assumptions quickly. +- Verification habits: the user’s expectations for tests/lints/sanity checks, and what + “done” means in practice. +- Pitfalls and fixes: recurring failure modes, common symptoms/error strings to watch for, and the proven fix. +- Reusable artifacts: templates/checklists/snippets that consistently used and helped + in the past (what they’re for and when to use them). +- Efficiency tips: ways to reduce tool calls/tokens, stop rules, and when to switch strategies. +- Give extra weight to guidance that helps the agent proactively do the things the user + often has to ask for repeatedly or avoid the kinds of overreach that trigger interruption. + +## What's in Memory + +This is a compact index to help future agents quickly find details in `MEMORY.md`, +`skills/`, and `rollout_summaries/`. +Treat it as a routing/index layer, not a mini-handbook: + +- tell future agents what to search first, +- preserve enough specificity to route into the right `MEMORY.md` block quickly. + +Topic selection and quality rules: + +- Organize the index first by project scope, then by topic. +- Split the index into a recent high-utility window and older topics. +- Do not target a fixed topic count. Include informative topics and omit low-signal noise. +- Prefer grouping by task family / workflow intent, not by incidental tool overlap alone. +- Order topics by utility, using `updated_at` recency as a strong default proxy unless there is + strong contrary evidence. +- Each topic bullet must include: topic, keywords, and a clear description. +- Keywords must be representative and directly searchable in `MEMORY.md`. + Prefer exact strings that a future agent can search for (project names, user query phrases, + tool names, error strings, commands, file paths, APIs/contracts). Avoid vague synonyms. +- Use a short project scope label that groups closely related tasks into one practical area. +- Use source-faithful topic labels and descriptions: + - prefer labels built from the rollout/task wording over newly invented abstract categories; + - prefer exact phrases from `description:`, `task:`, and user wording when those phrases are + already discriminative; + - if a combined topic must cover multiple rollouts, preserve at least a few original strings + from the underlying tasks so the abstraction does not erase retrieval handles. + +Required subsection structure (in this order): + +After the top-level sections `## User Profile`, `## User preferences`, and `## General Tips`, +structure `## What's in Memory` like this: + +### + +#### + +Recent Active Memory Window behavior (scope-first, then day-ordered): + +- Define a "memory day" as a calendar date (derived from `updated_at`) that has at least one + represented memory/rollout in the current memory set. +- Build the recent window from the most recent meaningful topics first, then group those topics + by their best project scope. +- Within each scope, order day subsections by recency. +- If a scope has only one meaningful recent day, include only that day for that scope. +- For each recent-day subsection inside a scope, prioritize informative, likely-to-recur topics and make + those entries richer (better keywords, clearer descriptions, and useful recent learnings); + do not spend much space on trivial tasks touched that day. +- Preserve routing coverage for `MEMORY.md` in the overall index.

Assistant summaries are secondary evidence about how the agent responded. +- Pure discussion, brainstorming, and tentative design talk should usually stay in the + rollout summary unless there is clear evidence that the conclusion held. + +============================================================ +HOW TO READ A ROLLOUT +============================================================ + +When deciding what to preserve, read the rollout in this order of importance: + +1. User messages + - strongest source for preferences, constraints, acceptance criteria, dissatisfaction, + and "what should have been anticipated" +2. Tool outputs / verification evidence + - strongest source for system facts, failures, commands, exact artifacts, and what actually worked +3. Assistant actions/messages + - useful for reconstructing what was attempted and how the user steered the agent, + but not the primary source of truth for user preferences + +What to look for in user messages: + +- repeated requests +- corrections to scope, naming, ordering, visibility, presentation, or editing behavior +- points where the user had to stop the agent, add missing specification, or ask for a redo +- requests that could plausibly have been anticipated by a stronger agent +- near-verbatim instructions that would be useful defaults in future runs + +General inference rule: + +- If the user spends keystrokes specifying something that a good future agent could have + inferred or volunteered, consider whether that should become a remembered default. + +============================================================ +EXAMPLES: USEFUL MEMORIES BY TASK TYPE +============================================================ + +Coding / debugging agents: + +- Project orientation: key directories, entrypoints, configs, structure, etc. +- Fast search strategy: where to grep first, what keywords worked, what did not. +- Common failure patterns: build/test errors and the proven fix. +- Stop rules: quickly validate success or detect wrong direction. +- Tool usage lessons: correct commands, flags, environment assumptions. + +Browsing/searching agents: + +- Query formulations and narrowing strategies that worked. +- Trust signals for sources; common traps (outdated pages, irrelevant results). +- Efficient verification steps (cross-check, sanity checks). + +Math/logic solving agents: + +- Key transforms/lemmas; “if looks like X, apply Y”. +- Typical pitfalls; minimal-check steps for correctness. + +============================================================ +TASK OUTCOME TRIAGE +============================================================ + +Before writing any artifacts, classify EACH task within the rollout. +Some rollouts only contain a single task; others are better divided into a few tasks. + +Outcome labels: + +- outcome = success: task completed / correct final result achieved +- outcome = partial: meaningful progress, but incomplete / unverified / workaround only +- outcome = uncertain: no clear success/failure signal from conversation evidence +- outcome = fail: task not completed, wrong result, stuck loop, tool misuse, or user dissatisfaction + +Rules: + +- Use the explicit `terminal_metadata` block from the user message as a first-class signal. +- Infer from conversation evidence using these heuristics and your best judgment. + +Terminal metadata guidance: + +- `completed` means the run ended with a final output, but individual tasks can still be + partial or uncertain if the evidence says so. +- `interrupted` means the run stopped for approvals or another resumable interruption. + Do not treat interruption as automatic failure; focus on what had or had not been + accomplished before the interruption. +- `cancelled` means the run was stopped before completion. Usually prefer `partial` or + `uncertain` unless there is strong contrary evidence. +- `failed`, `max_turns_exceeded`, and `guardrail_tripped` are strong negative signals for the + overall run outcome, but you should still preserve any reusable partial progress. + +Typical real-world signals (use as examples when analyzing the rollout): + +1. Explicit user feedback (obvious signal): + - Positive: "works", "this is good", "thanks" -> usually success. + - Negative: "this is wrong", "still broken", "not what I asked" -> fail or partial. +2. User proceeds and switches to the next task: + - If there is no unresolved blocker right before the switch, prior task is usually success. + - If unresolved errors/confusion remain, classify as partial (or fail if clearly broken). +3. User keeps iterating on the same task: + - Requests for fixes/revisions on the same artifact usually mean partial, not success. + - Requesting a restart or pointing out contradictions often indicates fail. + - Repeated follow-up steering is also a strong signal about user preferences, + expected workflow, or dissatisfaction with the current approach. +4. Last task in the rollout: + - Treat the final task more conservatively than earlier tasks. + - If there is no explicit user feedback or environment validation for the final task, + prefer `uncertain` (or `partial` if there was obvious progress but no confirmation). + - For non-final tasks, switching to another task without unresolved blockers is a stronger + positive signal. + +Signal priority: + +- Explicit user feedback and explicit environment/test/tool validation outrank all heuristics. +- If heuristic signals conflict with explicit feedback, follow explicit feedback. + +Fallback heuristics: + +- Success: explicit "done/works", tests pass, correct artifact produced, user + confirms, error resolved, or user moves on after a verified step. +- Fail: repeated loops, unresolved errors, tool failures without recovery, + contradictions unresolved, user rejects result, no deliverable. +- Partial: incomplete deliverable, "might work", unverified claims, unresolved edge + cases, or only rough guidance when concrete output was required. +- Uncertain: no clear signal, or only the assistant claims success without validation. + +Additional preference/failure heuristics: + +- If the user has to repeat the same instruction or correction multiple times, treat that + as high-signal preference evidence. +- If the user discards, deletes, or asks to redo an artifact, do not treat the earlier + attempt as a clean success. +- If the user interrupts because the agent overreached or failed to provide something the + user predictably cares about, preserve that as a workflow preference when it seems likely + to recur. +- If the user spends extra keystrokes specifying something the agent could reasonably have + anticipated, consider whether that should become a future default behavior. + +This classification should guide what you write. If fail/partial/uncertain, emphasize +what did not work, pivots, and prevention rules, and write less about +reproduction/efficiency. Omit any section that does not make sense. + +============================================================ +DELIVERABLES +============================================================ + +Return exactly one JSON object with required keys: + +- `rollout_summary` (string) +- `rollout_slug` (string) +- `raw_memory` (string) + +`rollout_summary` and `raw_memory` formats are below. `rollout_slug` is a +filesystem-safe stable slug to best describe the rollout (lowercase, hyphen/underscore, <= 80 chars). + +Rules: + +- Empty-field no-op must use empty strings for all three fields. +- No additional keys. +- No prose outside JSON. + +============================================================ +`rollout_summary` FORMAT +============================================================ + +Goal: distill the rollout into useful information, so that future agents usually don't need to +reopen the raw rollouts. +You should imagine that the future agent can fully understand the user's intent and +reproduce the rollout from this summary. +This summary can be comprehensive and detailed, because it may later be used as a reference +artifact when a future agent wants to revisit or execute what was discussed. +There is no strict size limit, and you should feel free to list a lot of points here as +long as they are helpful. +Do not target fixed counts (tasks, bullets, references, or topics). Let the rollout's +signal density decide how much to write. +Instructional notes in angle brackets are guidance only; do not include them verbatim in the rollout summary. + +Important judgment rules: + +- Rollout summaries may be more permissive than durable memory, because they are reference + artifacts for future agents who may want to execute or revisit what was discussed. +- The rollout summary should preserve enough evidence and nuance that a future agent can see + how a conclusion was reached, not just the conclusion itself. +- Preserve epistemic status when it matters. Make it clear whether something was verified + from code/tool evidence, explicitly stated by the user, inferred from repeated user + behavior, proposed by the assistant and accepted by the user, or merely proposed / + discussed without clear adoption. +- Overindex on user messages and user-side steering when deciding what is durable.

If a lesson comes from what the user asked + the agent to do, show enough of the specific user steering to give context, for example: + "the user asked to ... indicating that ..." +- Do not over-index on exploratory discussions or brainstorming sessions because these can + change quickly, especially when they are single-turn. Especially do not write down + assistant messages from pure discussions as durable memory. If a discussion carries any + weight, it should usually be framed as "the user asked about ..." rather than "X is true." + These discussions often do not indicate long-term preferences. + +Use an explicit task-first structure for rollout summaries. + +- Do not write a rollout-level `User preferences` section. +- Preference evidence should live inside the task where it was revealed. +- Use the same task skeleton for every task in the rollout; omit a subsection only when it is truly empty. + +Template: + +# + +Rollout context: + + + +## Task : + +Outcome: + +Preference signals: + +- Preserve quote-like evidence when possible. +- Prefer an evidence -> implication shape on the same bullet: + - when , the user said / asked / corrected: "" -> what that suggests they want by default (without prompting) in similar situations +- Repeated follow-up corrections, redo requests, interruption patterns, or repeated asks for + the same kind of output are often the highest-value signal in the rollout. + - if the user interrupts, this may indicate they want more clarification, control, or discussion + before the agent takes action in similar situations + - if the user prompts the logical next step without much extra specification, such as + "address the feedback", "go ahead and publish this", "now write the summary", + or "use the same naming pattern as before", this may indicate a default the agent should + have anticipated without being prompted +- Preserve near-verbatim user requests when they are reusable operating instructions. +- Keep the implication only as broad as the evidence supports. +- Split distinct preference signals into separate bullets when they would change different future + defaults. Do not merge several concrete requests into one vague umbrella preference. +- Good examples: + - after the agent hit a validation failure, the user asked the agent to + "explain what failed and propose a fix before changing anything" -> + this suggests that when validation fails, the user wants the agent to diagnose first + and propose a fix before editing. + - after the agent only preserved a final answer, the user asked for the surrounding context + and failure details to be included -> this suggests the user wants enough context to inspect + failures directly, not just the final output. + - after the agent named artifacts by broad topic, the user renamed or asked to rename + them by the behavior being validated -> this suggests the user prefers artifact names that + encode what is being validated, not just the topic area. +- If there is no meaningful preference evidence for this task, omit this subsection. + +Key steps: + +- (optional evidence refs: [1], [2], + ...) +- Keep this section concise unless the steps themselves are highly reusable.
