dsh-git-branch
English | 中文
Show the current workspace git branch right after the composer mode controls (access mode / plan) in the DeepSeek Harness (DSH) Web UI. It renders only when the workspace is inside a git repository, and it refreshes automatically when you switch branches in another tool.
Where it appears
The composer tool row is laid out as [+ commands] [access mode] [plan] ← branch chip. This plugin registers into the conversation.input.left slot — the additive seat immediately after the resident mode chrome — so the branch chip sits right next to the mode controls.
- Branch:
⎇ main
- Detached HEAD:
⎇ detached @ a1b2c3d
- Not a git repository: nothing renders
- Click the chip: refresh immediately (tooltip explains)
Install
The package is a DSH bundle (it ships its own cordis.patch.yml), so dsh plugin add both installs the dependency and activates it — no manual config:
# from npm
dsh plugin --profile web add dsh-git-branch
# or a local checkout (development)
dsh plugin --profile web add ./dsh-git-branch
Then restart the profile and refresh the page:
# restart dsh web, then reload the browser tab
How it works: package.json declares dsh.bundle.patch = ./cordis.patch.yml, which - inserts one git-branch plugin row. dsh plugin add detects dsh.bundle and adds the package to dsh.profile.bundles; on the next boot that patch layer takes effect, the host loads the host half, and the client half is served to the browser automatically.
Optional host config
To change the command name, override the row (same id) in your own profile cordis.patch.yml:
- id: git-branch
name: dsh-git-branch
config:
commandName: git-branch # optional; default is git-branch
Unknown config keys fail at load.
Client refresh constant
See the top of src/client/index.tsx (or lib/client.js):
POLL_INTERVAL_MS = 60000: slow safety-net poll; <= 0 disables it.
How it works
- host:
lib/index.js registers the /git-branch command; the handler walks up from session.header.cwd to the nearest .git (worktrees and submodules included), parses HEAD, and returns the result as JSON in the command's text field.
- client:
lib/client.js registers the conversation.input.left chip, fetches the branch through ctx.remote.commands.execute, and registers a conversation.chat.commandview entry for git-branch that renders null, hiding the transport command from the transcript.
Refresh triggers (see DESIGN.md): mount / session-or-workspace switch → immediate; window focus → immediate; visibilitychange → visible → immediate; chip click → immediate; 60s poll → fallback.
