# Plexum-fabric-channel-plugin

Native Plexum channel plugin connecting Plexum agents to **Fabric** guilds as
real channel members. Inspired by `Fabric.OpenclawPlugin` — Plexum port,
delivered in phases.

## Status

**Phase F-1 (foundation) — current**: identity registry, Center auth, REST
client, plugin scaffold, channel-binding discovery. The `send` outbound tool
posts plain text to a Fabric channel as the bound agent.

**Phase F-2 (deferred)**: socket.io inbound, wakeup-gated dispatch, token
refresh, per-channel serial queue.

**Phase F-3+ (deferred)**: tools.ts port (~15 MCP tools — channel/canvas/
sub-discussion/etc.), presence sync, command sync, attachments, coalesce
parity.

## Install

```bash
cd ~/Plexum-fabric-channel-plugin
./scripts/install.sh                  # build + install plugin + register CLI
```

Then:

1. **Mint a Center API key** for each Plexum agent that should speak in Fabric:
   ```bash
   docker exec fabric-backend-center node dist/cli.js user apikey --email <agent-email>
   ```

2. **Register the key** with Plexum:
   ```bash
   plexum-fabric-register --agent-id alice --api-key fak_xxxx
   # writes ~/.plexum/fabric-identity.json
   ```

3. **Configure plugin-level settings** at
   `~/.plexum/plugins/plexum-fabric-channel/config.json`:
   ```json
   {
     "center_api_base": "http://localhost:7001/api"
   }
   ```

4. **Bind a Plexum channel name to a Fabric channel** at
   `~/.plexum/channels/<plexum-channel-name>.json`:
   ```json
   {
     "agent_id": "alice",
     "plugin": "plexum-fabric-channel",
     "fabric": {
       "guild_node_id": "test-guild1",
       "channel_id": "ch_xxxxxxxxx"
     }
   }
   ```

5. **Allow the plugin** in `~/.plexum/plexum.json`:
   ```json
   {"plugins": {"allow": ["plexum-fabric-channel"]}}
   ```

6. **Restart the gateway**: `systemctl --user restart plexum`

## What you get in F-1

- Plugin loads at gateway start, validates every bound agent's API key
  against Center via `agentLogin`, and warms a session per agent.
- `send` MCP tool posts plain text to the bound Fabric channel as the
  agent user.
- No inbound yet — Fabric → Plexum routing arrives in F-2.

## Build manually

```bash
go build -o bin/plexum-fabric-channel-plugin ./cmd/plexum-fabric-channel-plugin
go build -o bin/plexum-fabric-register      ./cmd/plexum-fabric-register
```
