Bundles the remaining "agent does things in Fabric" surface, skipping
presence-sync (Plexum's state machine isn't 1:1 with HF status semantics)
and attachments (Plexum has no media pipeline yet) — both deferred.

- atomic tmp+rename persistence; corrupt file = start empty
internal/tools/tools.go — 7 new tools:
- create-chat-channel (xType=general)
- create-work-channel (xType=work)
- create-report-channel (xType=report)
- create-discussion-channel (xType=discuss)
- discussion-complete (post summary + close channel)
- create-sub-discussion (create + invite + KV store + greeting)
- close-sub-discussion (host-only; posts callback to parent + closes)

JoinChannel / LeaveChannel / SetChannelPurpose / Canvas CRUD /
SyncCommands (added in earlier F-4 commit; reused here)
cmd/plexum-fabric-channel-plugin/main.go:
- subdisc.Store opened from DefaultPath at init; passed into tools.Deps
- HostConfig adds commands_sync_key + sync_commands (defaults
["new","stop"]) — F-5 command-sync to every (agent,guild) pair at
init when key is set; silently skips when omitted
- syncCommandsToGuilds: best-effort PUT per guild, logs per-guild
outcome
scripts/install.sh: manifest tools[] expanded to 16 entries
(9 from F-4 + 7 new). create-channel variants share a schema shape.
Live verified:
$ plexum plugin-call create-chat-channel \
'{"agent_id":"fabrictester","guild_node_id":"test-guild2",
"name":"plexum-f7-smoke","is_public":true}'
→ "created general channel plexum-f7-smoke (id=6315e636-...)"
$ plexum plugin-call fabric-channel-list ...
→ 3 channels listed including the new one
F-6 (attachments) + F-5b (presence-sync) + F-8 (coalesce) deliberately
deferred — see DEV-NOTES.
Tests: 5 new in internal/subdisc (27 total in this repo).

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
cd ~/Plexum-fabric-channel-plugin
./scripts/install.sh # build + install plugin + register CLI
Then:
-
Mint a Center API key for each Plexum agent that should speak in Fabric:
docker exec fabric-backend-center node dist/cli.js user apikey --email <agent-email> -
Register the key with Plexum:
plexum-fabric-register --agent-id alice --api-key fak_xxxx # writes ~/.plexum/fabric-identity.json -
Configure plugin-level settings at
~/.plexum/plugins/plexum-fabric-channel/config.json:{ "center_api_base": "http://localhost:7001/api" } -
Bind a Plexum channel name to a Fabric channel at
~/.plexum/channels/<plexum-channel-name>.json:{ "agent_id": "alice", "plugin": "plexum-fabric-channel", "fabric": { "guild_node_id": "test-guild1", "channel_id": "ch_xxxxxxxxx" } } -
Allow the plugin in
~/.plexum/plexum.json:{"plugins": {"allow": ["plexum-fabric-channel"]}} -
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. sendMCP 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
