- Switched from registerAppBarComponent (not in MM 11.4 build) to
registerChannelHeaderButtonAction + registerRightHandSidebarComponent
- Added public/icon.svg for channel header button
- Fixed store dispatch for RHS toggle action
- Plugin deployment permissions fix (uid 2000)
Added a Right-Hand Sidebar (RHS) panel to the Mattermost plugin that
shows live agent activity in a dedicated, always-visible panel.
- New RHSPanel component with SessionCard views per active session
- registerAppBarComponent adds 'Agent Status' icon to toolbar
- Subscribes to WebSocket updates via global listener
- Shows active sessions with live elapsed time, tool calls, token count
- Shows recent completed sessions below active ones
- Responsive CSS matching Mattermost design system
The RHS panel solves the scroll-out-of-view problem: the status
dashboard stays visible regardless of chat scroll position.
- Fix lint errors in plugin-client.js (unused var, empty block)
- Update README with plugin architecture and env vars
- Update STATE.json to v4.1 IMPLEMENTATION_COMPLETE
- All 96 tests passing, 0 lint errors
Plugin (Go server + React webapp):
- Custom post type 'custom_livestatus' with terminal-style rendering
- WebSocket broadcasts for real-time updates (no PUT, no '(edited)')
- KV store for session persistence across reconnects
- Shared secret auth for daemon-to-plugin communication
- Auto-scroll terminal with user scroll override
- Collapsible sub-agent sections
- Theme-compatible CSS (light/dark)
Daemon integration:
- PluginClient for structured data push to plugin
- Auto-detection: GET /health on startup + periodic re-check
- Graceful fallback: if plugin unavailable, uses REST API (PUT)
- Per-session mode tracking: sessions created via plugin stay on plugin
- Mid-session fallback: if plugin update fails, auto-switch to REST
Plugin deployed and active on Mattermost v11.4.0.
