# Zero-to-hero support desk
# Support desk
A maintained 0-to-hero reference for the Go Micro lifecycle: scaffold a few
typed services, run them in one process, let an agent chat with those services
as tools, then inspect the durable flow that triggered the work. It is one
runnable file and one CI smoke test, so the reference path stays honest as the
framework evolves.
## The path
1. **Scaffold services**`customers`, `tickets`, and `notify` are ordinary
typed Go Micro services. Their request/response structs and method comments
become the tool contract the agent sees.
2. **Run the harness** — the example starts an in-memory registry, broker,
client, store, services, agent, and flow in one process; no external
dependencies or API key are required for the default run.
3. **Chat through an agent** — the `support` agent receives the ticket event as
a prompt and calls service tools to look up the customer, triage the ticket,
and draft a reply.
4. **Inspect the workflow** — the `intake` flow records the event-driven run and
prints the agent result, showing the service → agent → workflow lifecycle as
one runtime.
A real-world agent built the Go Micro way: a few services, an agent that
manages them, an event that triggers it, and a human-in-the-loop gate on the
one action that touches a customer. It's the "zero to hero" shape in one
runnable file.

## Work queue (ranked)
1. **Broaden end-to-end agent streaming coverage** ([#3402](https://github.com/micro/go-micro/issues/3402)) — with durable agent checkpoint/resume guarded by #3406, streaming is now the highest-value Next-phase developer-visible seam: provider tokens need to move consistently through `ai.Stream`, `micro chat`, `Agent.Chat`, and A2A streaming. CI-safe local coverage plus provider-gated conformance should lock down chunk ordering, terminal/error events, and fallback behavior.
2. **Emit OpenTelemetry spans for agent runs** ([#3403](https://github.com/micro/go-micro/issues/3403)) — once long runs can resume and stream, operators need the same run story in traces that developers see via `micro runs`: lifecycle boundaries, model/tool calls, approvals, retries, failures, and cancellation correlated by run ID without leaking sensitive payloads.
1. **Add human-in-the-loop pause and resume for agent workflows** ([#3329](https://github.com/micro/go-micro/issues/3329)) — the highest-value remaining Later-phase operability gap now that provider conformance, failure hardening, the getting-started contract, streaming, durable resume/checkpoints, A2A task lifecycle, and `RunInfo` tracing have shipped. Scheduled and looping work still needs durable pending-input states that let humans approve, correct, or add context and then resume the same service/agent/workflow runtime.
2. **gateway/a2a: multiple typed skills per agent card** ([#3342](https://github.com/micro/go-micro/issues/3342)) — the A2A gateway now has the full task lifecycle (send/stream/get/cancel/resubscribe, push config, multi-turn, input-required); the remaining interop gap is skill granularity. `Card` only ever advertises one synthetic "chat" skill with services flattened into tags. Let an agent advertise N typed skills and route per skill, so domain-routing agents expose their real capabilities over A2A through the gateway instead of a hand-rolled handler.
3. **Add a maintained 0-to-hero reference example** ([#3368](https://github.com/micro/go-micro/issues/3368)) — keep the mission legible in code, not only docs: one CI-verifiable example should walk scaffold → run → chat → inspect across typed services, an agent, and a durable flow. This closes the remaining DX/coherence seam between the README promise, website roadmap, and the lived developer inner loop.
