Desktop Plugin Maker

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.

Verified placement contracts and the complete 25-position test matrix: references/position-surface-contracts.md. Load this reference whenever a plugin must move across panes, docks, bars, popovers, composer seams, routes, or sidebar navigation.
