dsh-web-ui

DSH Web UI plugin — one focused surface: a Codex-style right-docked file panel for the harness web profile. File tree on the left, read-only preview on the right, opened from a sidebar footer icon.

Surface

• Toggle — sidebar footer icon button (visible when the sidebar is open). Active state mirrors the panel's open/close.
• Panel — right-docked drawer, 420px wide. Slides in from the right edge.
  • Header: file name + close button.
  • Left: lazy file tree (workspace root → directories → files; directories collapse by default, click to expand).
  • Right: read-only preview pane with file size + path footer.
• Hotkey — Ctrl/Cmd + Shift + R toggles the panel.

Default state is closed; the user opens it via the toggle.

Install

dsh plugin --profile web add dsh-web-ui

The plugin resolves through the profile's node_modules; the cordis.patch.yml inserts the plugin row into the profile's loader stack.

Wire contract

All host endpoints live under /api/dsh-web-ui/ and respond with the envelope:

{ "ok": true, "value": ... }
{ "ok": false, "error": { "code": 403, "message": "..." } }

Both routes realpath-validate path against the active workspace root and reject anything outside as 403. The plugin does not read arbitrary paths.

Build

pnpm install
pnpm build       # tsc -p tsconfig.build.json && tsdown
pnpm typecheck

Why one client bundle

DSH plugins with a scoped npm name (@scope/pkg) ship two CJS bundles: one registering as the package name (@scope/pkg, the official channel) and one as the manifest id (scope/pkg/registry, the registry channel). For a non-scoped plugin like this one, the two channels collapse to one id — dsh-web-ui — so lib/client-registry.js is the single artifact and dsh.plugin.json's client.main points at it.
