# First Agent
|
|
|
|
This is the smallest runnable service-backed agent in the repository. It sits
|
|
between `micro new helloworld` and the full [`examples/support`](../support/)
|
|
0→hero reference.
|
|
|
|
It runs with a deterministic mock model, so you do not need `ANTHROPIC_API_KEY`,
|
|
`OPENAI_API_KEY`, or any other provider secret.
|
|
|
|
```bash
|
|
go run ./examples/first-agent
|
|
```
|
|
|
|
Expected transcript:
|
|
|
|
```text
|
|
First agent (provider: mock, no API key)
|
|
> Summarize my next steps
|
|
[notes] listed starter notes
|
|
assistant: Your first agent read the notes service and found three steps: install the CLI, run a service, then chat with an agent.
|
|
✓ service-backed agent completed without provider secrets
|
|
```
|
|
|
|
## What it demonstrates
|
|
|
|
- `notes` is a normal Go Micro service with one RPC method.
|
|
- `assistant` is an agent scoped to that service via `agent.Services("notes")`.
|
|
- The mock model requests the service tool through the normal agent tool handler.
|
|
- The final answer proves the service → agent path without a live model key.
|
|
|
|
CI keeps this path runnable with:
|
|
|
|
```bash
|
|
go test ./examples/first-agent
|
|
```
|
|
|
|
## Next chat, inspect, and debug breadcrumbs
|
|
|
|
This example exits after one in-process `assistant.Ask` call so it stays tiny and
|
|
provider-free. When you move from this transcript to a long-running agent, keep
|
|
these commands nearby:
|
|
|
|
```bash
|
|
micro run
|
|
micro chat assistant --prompt "Summarize my next steps"
|
|
micro inspect agent assistant
|
|
micro agent doctor assistant
|
|
```
|
|
|
|
Use the [no-secret first-agent guide](../../internal/website/docs/guides/no-secret-first-agent.md)
|
|
to compare this transcript with the CLI demo, then keep the
|
|
[debugging guide](../../internal/website/docs/guides/debugging-agents.md) open for
|
|
preflight, doctor, inspect, and history checks. After that, continue to
|
|
[`examples/support`](../support/) for the full services → agents → workflows
|
|
lifecycle with a flow trigger and an approval gate.
