Add a plugin system that lets plugins add new tabs to the dashboard.
Plugins live in ~/.hermes/plugins/<name>/dashboard/ alongside any
existing CLI/gateway plugin code.
Plugin structure:
plugins/<name>/dashboard/
manifest.json # name, label, icon, tab config, entry point
dist/index.js # pre-built JS bundle (IIFE, uses SDK globals)
plugin_api.py # optional FastAPI router mounted at /api/plugins/<name>/
Backend (hermes_cli/web_server.py):
- Plugin discovery: scans plugins/*/dashboard/manifest.json from user,
bundled, and project plugin directories
- GET /api/dashboard/plugins — returns discovered plugin manifests
- GET /api/dashboard/plugins/rescan — force re-discovery
- GET /dashboard-plugins/<name>/<path> — serves plugin static assets
with path traversal protection
- Optional API route mounting: imports plugin_api.py and mounts its
router under /api/plugins/<name>/
- Plugin API routes bypass session token auth (localhost-only)
Frontend (web/src/plugins/):
- Plugin SDK exposed on window.__HERMES_PLUGIN_SDK__ — provides React,
hooks, UI components (Card, Badge, Button, etc.), API client,
fetchJSON, theme/i18n hooks, and utilities
- Plugin registry on window.__HERMES_PLUGINS__.register(name, Component)
- usePlugins() hook: fetches manifests, loads JS/CSS, resolves components
- App.tsx dynamically adds nav items and routes for discovered plugins
- Icon resolution via static map of 20 common Lucide icons (no tree-
shaking penalty — bundle only +5KB over baseline)
Example plugin (plugins/example-dashboard/):
- Demonstrates SDK usage: Card components, backend API call, SDK reference
- Backend route: GET /api/plugins/example/hello
Tested: plugin discovery, static serving, API routes, path traversal
blocking, unknown plugin 404, bundle size (400KB vs 394KB baseline).
