 Go Micro is an **agent harness** and service framework for Go.

-A harness is the runtime around an agent: the tools it can call, the memory it keeps, the guardrails that bound it, the workflows that trigger it, the services it depends on, and the protocols other agents use to reach it. 
-
-Go Micro gives you the harness as Go code. Build an agent and it gets a model, memory, tools, planning, delegation, guardrails, and service discovery; it is reachable over [MCP](https://modelcontextprotocol.io/) and [A2A](https://a2a-protocol.org). Write services and every endpoint becomes an AI-callable tool. Orchestrate the deterministic parts with durable flows. Agents, services, and flows share one runtime because an agent is a distributed system, and building one is building a service.

-micro ai providers

-For automation and docs generation, emit the same matrix as stable JSON:

-### Service Name vs Package Name
+### Option Ordering Issue

-When creating a client to call another service, use the **service name** passed to `micro.NewService`, not the proto package name:
+If the gRPC server is working but your service has no name or is not being found in the registry:
+
+**Cause**: The `micro.Server()` option is specified **after** `micro.Name()`.

-# Provider Conformance Matrix
-
-Go Micro treats model providers as interchangeable pieces of the same agent
-harness: services expose tools, agents reason over them, and workflows stitch the
-work together. The conformance harness keeps that promise honest by running the
-same deterministic services → agents → workflows scenarios against every
-configured provider.
-
-The live harness is in `internal/harness/provider-conformance`. It skips
-providers without API keys by default, so it is safe to run locally, and it fails
-when any configured provider breaks the shared contract.
-
-```sh
-go run ./internal/harness/provider-conformance
-```
-
-For a no-key smoke test of the same harness wiring, run the mock provider:
-
-```sh
-go run ./internal/harness/provider-conformance -providers mock
-```
-
-## Status legend
-
-| Status | Meaning |
-| --- | --- |
-| ✅ Verified | Covered by the provider-conformance harness for configured live providers. |
-| ⚠️ Unverified | Implemented in the public API, but not yet exercised by provider conformance. |
-| — Unsupported | Not exposed by that provider integration today. |
-
-## Harness coverage by capability
-
-These rows describe what the conformance harness verifies today. A provider is
-considered conformant when the configured-key run passes all selected harnesses.
-
-| Capability | Harness coverage | Notes |
-| --- | --- | --- |
-| Simple generation | ✅ Verified | Each harness asks the provider to produce an agent response through `ai.Model`. |
-| Service tool calls | ✅ Verified | Harness services are discovered and invoked as model-selected tools. |
-| Multi-step tool use | ✅ Verified | The `universe` and `plan-delegate` harnesses require more than one service/tool action. |
-| `plan` | ✅ Verified | `plan-delegate` verifies that the conductor agent stores a plan in scoped state. |
-| `delegate` | ✅ Verified | `plan-delegate` verifies agent-to-agent delegation over real RPC. |
-| Guardrail/stop behavior | ✅ Verified | `universe` runs with guardrails enabled and asserts the guarded path completes. |
-| Streaming | ⚠️ Unverified | `ai.Model.Stream` exists on the interface, but end-to-end streaming conformance is a roadmap item. |
-| Structured errors | ⚠️ Unverified | Error handling is covered by normal test suites, but provider conformance does not yet compare structured provider errors. |
-
-## Provider capability matrix
-
-This matrix combines the registered provider interfaces with the conformance
-coverage above. The chat/text column is the harness path: when the provider has a
-configured key, the conformance command exercises the verified rows in the
-previous section.
-
-| Provider | Chat/text agent harness | Image | Video | Streaming | Structured errors |
-| --- | --- | --- | --- | --- | --- |
-| `anthropic` | ✅ Verified when configured | — Unsupported | — Unsupported | ⚠️ Unverified | ⚠️ Unverified |
-| `openai` | ✅ Verified when configured | ✅ Registered | — Unsupported | ⚠️ Unverified | ⚠️ Unverified |
-| `gemini` | ✅ Verified when configured | — Unsupported | — Unsupported | ⚠️ Unverified | ⚠️ Unverified |
-| `groq` | ✅ Verified when configured | — Unsupported | — Unsupported | ⚠️ Unverified | ⚠️ Unverified |

-| `atlascloud` | ✅ Verified when configured | ✅ Registered | ✅ Registered | ⚠️ Unverified | ⚠️ Unverified |
-
-## Running a focused check
-
-Use `-providers` to select a provider and `-harnesses` to narrow the scenario:
-
-```sh
-go run ./internal/harness/provider-conformance \
-  -providers openai,anthropic \
-  -harnesses agent-flow,plan-delegate
-```
-
-By default missing live-provider keys are reported as skips. Add
-`-require-configured` in CI when a selected provider must be present:
-
-```sh
-go run ./internal/harness/provider-conformance \
-  -providers openai \
-  -require-configured
-```
-
-The command also prints the registered model, image, and video provider
-capabilities before running conformance. Disable that with `-capabilities=false`
-when you only want pass/fail output.
-
-For automation, add `-summary-json` to capture the selected providers,
-harnesses, registered capability rows, and pass/skip/fail results in a stable
-machine-readable file. Add `-capabilities-markdown` when you also want a
-ready-to-publish Markdown support table for release notes, docs, or issue
-updates:
-
-```sh
-go run ./internal/harness/provider-conformance \
-  -providers mock \

 Different tools can cost different amounts. Pricing is an **operator** concern — the payTo address is the operator's, and amounts change without redeploying anyone's service — so it's configured at the gateway with a file, the same way per-tool scopes and rate limits are. Point the gateway at an x402 config:

 ```bash
-micro mcp serve --address :3000 --x402_config x402.json

-`amount` is the default (here `"0"` — free unless priced), and `amounts` sets per-tool overrides keyed by tool name. There is no "pricing" abstraction; it's the x402 `amount`, resolved per tool, in the protocol's own vocabulary. `micro mcp serve` accepts the file via `--x402_config`; the standalone gateway accepts the same file via `--x402-config` or the `X402_CONFIG` environment variable.
