+### AGENTS.md auto-generation
+
+At startup, every workspace automatically generates `/workspace/AGENTS.md`
+from its `config.yaml`. The file follows the
+[AAIF (Agent Artifact Interchange Format)](https://github.com/google/A2A) standard
+and contains:
+
+| Section | Source |
+|---------|--------|
+| Name | `config.yaml → name` |
+| Role | `config.yaml → role` (falls back to description) |
+| Description | `config.yaml → description` |
+| A2A Endpoint | `$AGENT_URL` env var, or `http://localhost:{a2a.port}/a2a` |
+| MCP Tools | union of `config.yaml → tools` + `plugins` |
+
+Peers fetch it via `GET /workspace/AGENTS.md` for capability discovery. Keep
+`name`, `role`, and `description` accurate in `config.yaml` — they are the
+sole source of truth for what this agent announces to the org.
+
+```yaml
+# config.yaml — relevant fields for AGENTS.md
+name: Backend Engineer
+role: "Owns the Go platform — API, migrations, tests, and CI gates."
+description: "Senior backend engineer focused on correctness, security, and performance."
+```
+
+The generator is non-fatal: a missing or unreadable `config.yaml` prints a
+startup warning but does not prevent the workspace from booting.
