First Agent

This is the smallest runnable service-backed agent in the repository. It sits between micro new helloworld and the full examples/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

After this, continue to examples/support for the full services → agents → workflows lifecycle with a flow trigger and an approval gate.
