feat: Phase F-5+F-7 — command-sync + sub-discussion + channel-create tools
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.
internal/subdisc/ (~140 LOC + 5 tests): persistent KV at
<profile>/state/plugin-kv/fabric-sub-discussions.json
- Entry: SubChannelID, HostAgentID, HostUserID, GuestUserIDs,
HostGuide, GuestGuide, CallbackGuildNodeID, CallbackChannelID, CreatedAt
- Open / Lookup / LookupForHost (host-enforcement) / Add / Remove / All
- 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)
internal/fabric/client.go: CreateChannel / CloseChannel /
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).
