+### Agent naming convention
+
+Use **functional names** based on domain, not model names:
+
+| Subproject | Agent name | Git signature |
+|------------|-----------|---------------|
+| `clavis-vault` | `vault-agent` | `vault-agent <session-id>` |
+| `clavis-cli` | `cli-agent` | `cli-agent <session-id>` |
+| `clavis-chrome/firefox/safari` | `extension-agent` | `extension-agent <session-id>` |
+| `clavis-crypto` | `crypto-agent` | `crypto-agent <session-id>` |
+| `clavitor.ai/admin` | `central-agent` | `central-agent <session-id>` |
+| Cross-cutting / architecture | `architect-agent` | `architect-agent <session-id>` |
+| Security reviews | `security-agent` | `security-agent <session-id>` |
+
+**Why:** Release notes show "vault-agent added rate limiting" not "Claude added rate limiting." The domain matters, the model doesn't.
+
+**Commit signature format:**
+```
+Author: vault-agent <20250408-001>
+Author: cli-agent <20250408-003>
+```
+
