Hermes Desktop Plugins Skill

Write plugins for the Hermes desktop app: statusbar items, layout panes, command-palette commands, keybinds, routes, and themes. A plugin is a single plain-JavaScript ESM file the app loads at runtime — no build step, no repo changes. A plugin can also talk to its own Python backend namespace (ctx.rest/ctx.socket → /api/plugins/<id>); the general Python plugin system (~/.hermes/plugins/) is otherwise documented separately.

Full human reference (every export, area payloads, backend, security): website/docs/developer-guide/desktop-plugin-sdk.md.

When to Use

• The user asks for a new desktop UI element (a pane, a statusbar widget, a dashboard, a command) without modifying the app itself.
• You want to surface data you compute (via gateway RPC) inside the app.
