قناة Raft

Hermes connects to Raft ↗ as an external agent through a local wake-channel bridge. The adapter starts a loopback HTTP endpoint that receives content-free wake hints from the bridge, then injects them into the Hermes gateway session pipeline. The agent reads and sends messages through the Raft CLI — the adapter never touches message bodies or delivery cursors.

---

• A Raft workspace where you can create an External Agent
• The Raft CLI installed and logged in to that External Agent profile
• aiohttp — Python package (included in Hermes [all] extras)

In Raft, open the Agents menu, create an External Agent, and follow the setup card to install the Raft CLI and log in the agent profile. Once the agent is created, Raft shows a Hermes setup guide with the environment variables and configuration needed to start the gateway.

Add to ~/.hermes/.env:

RAFT_PROFILE=your-agent-profile

That's it — the adapter auto-enables when RAFT_PROFILE is set. It generates a per-session bridge token, picks an ephemeral port, and spawns the bridge child process automatically when the gateway starts.

Raft Server → Bridge (wake-hints SSE) → POST /wake → Hermes Adapter → Agent context
Agent → raft message check → Raft Server (message bodies)
Agent → raft message send → Raft Server (replies)

1. The Raft server sends wake hints to the bridge process via SSE.
2. The bridge forwards each hint as a POST /wake to the adapter's loopback endpoint.
3. The adapter validates the bridge token, verifies the payload is content-free, and injects a wake notice into the Hermes session.
4. The agent sees the wake notice and uses the Raft CLI to read messages and reply.

Wake payloads are content-free by contract — they carry metadata (event ID, message ID, timestamps) but never message bodies, channel names, or sender identities. The adapter rejects any payload containing content-shaped fields (text, body, content, messages, etc.).

---

The adapter automatically spawns raft agent bridge as a child process, passing the endpoint URL and token. The bridge connects to the Raft server using the configured profile and begins forwarding wake hints. It is terminated when the gateway shuts down.
