dsh-custom-ui

dsh-custom-ui

Custom UI plugin for DeepSeek Harness Web.

Adds a right-side file-tree sidebar, workspace file open, and a DeepSeek account balance meter in the composer stats line.

Features

• Balance meter — shows the DeepSeek account balance in the composer stats line. The API key is resolved server-side only through the credentials seam (credentialRef from @deepseek-ai/dsh-credentials) — it never crosses the wire to the browser.
• File tree sidebar — a right-side workspace file tree for quick navigation, with collapse/expand and a floating toggle button.
• Workspace file open — open files/folders with the system default application (workspace-rooted; path traversal guarded).

Install

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

Then restart dsh web. If installed from a local checkout instead, link it via pnpm link (or "dsh-custom-ui": "link:<path>" in the profile's package.json) and rebuild.

Requirements

• DeepSeek Harness Web (dsh web)
• DEEPSEEK_API_KEY configured in the harness credentials (for the balance meter; the file tree works without it)

Host routes

Development

# host half (server routes)
node lib/index.js            # or run through dsh plugin dev flow

# client half (browser UI) — HMR while `pnpm run dev:web` runs in the DSH checkout
# client-plugin changes reload without a refresh only while the dev:web watcher is running

Build the client bundle with your DSH toolchain, then restart dsh web.

Security

• The API key is resolved server-side only; the browser client never receives it.
• File routes are workspace-rooted: resolve() + prefix check against the workspace root blocks path traversal.
• Review lib/index.js and lib/client.js before installing if you did not clone from the official repo.
