dsh-codex-sidebar

English | 中文

A Codex-app-style right-hand sidebar for one DeepSeek Harness session. Files, Review, Browser, and Terminal share a tab strip on the current session.

What it does

Open a session, then use the sidebar toggle in the conversation header. The drawer occupies the details column of the DSH frame. It does not replace the chat.

• Files — read-only preview (source, Markdown, images) and a workspace tree. Click a path in the transcript to fill it.
• Review — this turn's changes from the session log, then leftover working-tree diffs. Read-only: no stage, revert, or commit.
• Browser — a managed Chromium document in that tab. The session can call browser_tabs, browser_open, browser_snapshot, browser_click, and browser_fill on loopback HTTP pages whether the sidebar is open or closed.
• Terminal — a human pty (script when present), not an agent shell.
• Annotations — click a line or a page to write a note at the mark. Send keeps the official user bubble; numbered chips sit under it. Locators and screenshots go to the model as evidence on that same user message.
• Edit +/− — each edit/write tool row shows the increment for that call, after the filename.

Chrome follows the DSH host theme. Tabs persist with that session. Side Chat is retired; cross-session questions belong to the DeepSeek assistant's task-reference flow.

Installation

DeepSeek Harness 0.1.0-rc.6 or later. Install from GitHub:

dsh plugin --profile web add github:NOirBRight/dsh-codex-sidebar#v0.2.6
dsh web

Lab (DSH_HOME=~/.dsh-lab) uses the same package name:

DSH_HOME=~/.dsh-lab dsh plugin --profile web add github:NOirBRight/dsh-codex-sidebar#v0.2.6

The repository tracks release-ready lib/ artifacts, so GitHub installation needs no build-script allowlist.

Do not list @deepseek-ai/dsh-tools (or other host singletons) as a plugin dependency. A hoisted copy shadows the host ToolRuntime and every tool call dies on .prepare.

Local install

pnpm install
pnpm test
pnpm run build
dsh plugin --profile web add "$(pwd)"
dsh web

Then open a session and use the sidebar toggle.
