Add an end-to-end developer guide for extending the native Hermes Desktop
app introduced in #60638: the HermesPlugin contract, PluginContext, every
contribution area (panes, routes, sidebar nav, status/title bar, palette,
keybinds, themes, composer, mount-scoped Contribute), the host API, the
React Query + nanostores data layer, the UI kit + theme variables, the
scoped ctx.rest/ctx.socket backend (plugin_api.py under /api/plugins/<id>)
and its separate enable gate, Settings/defaultEnabled/storage, bundled
plugins, the security model, pitfalls, and a full reference.
- Register the page in the sidebar under Extending -> Plugins.
- Disambiguate from the unrelated web-dashboard plugin SDK from both
directions, and add a map-table row + a desktop user-guide pointer.
- Fill the gaps in the agent-facing hermes-desktop-plugins skill
(ctx.rest/socket + backend, React Query, defaultEnabled, Contribute)
and point it at the new reference so agents know the SDK when writing
addons.
- New developer-guide/browser-provider-plugin.md: BrowserProvider ABC
(session lifecycle, CDP contract, bb_session_id back-compat key,
raise/never-raise split between create and close/cleanup),
get_setup_schema() hermes-tools integration, discovery, checklist.
Closes the one gap in the provider-plugin family — the ABC and
ctx.register_browser_provider() existed with zero docs.
- Register the page in the Plugins sidebar subcategory.
- Extend the routing map on the Plugins landing page (both locales)
with the previously missing rows: web-search, browser, secret-source,
and dashboard-auth surfaces.
* docs(secrets): secret-source plugin developer guide + sidebar registration for 1Password page
- New developer-guide/secret-source-plugin.md: SecretSource contract
(never raises/prompts, fetch-only, timeout budget), framework-vs-plugin
ownership table, mapped-vs-bulk shape guidance, run_secret_cli()
subprocess-safety, registration + timing note, conformance kit usage,
ErrorKind reference.
- Register user-guide/secrets/onepassword in the sidebar (page shipped
in #59498 but was not listed, so it was unreachable from nav).
- Cross-link the user-guide plugin section to the new dev guide.
* docs: group all plugin guides under a Plugins subcategory in Extending
- Move guides/build-a-hermes-plugin.md -> developer-guide/plugins/index.md
(both locales) and make it the category landing page (slug pinned to
/developer-guide/plugins).
- New sidebar subcategory Developer Guide > Extending > Plugins holding
the general guide + all 8 provider-plugin docs (llm-access, memory,
context-engine, secret-source, model, image-gen, video-gen, web-search);
provider-doc URLs unchanged.
- Client redirect /guides/build-a-hermes-plugin -> /developer-guide/plugins.
- Update 30 cross-links across both locales.
