dsh-git-workbench

Git and GitHub pull-request workflows for DeepSeek Harness, exposed both as model tools and as an integrated Web sidebar workbench.

Status: experimental. DeepSeek Harness is currently a developer preview and its plugin interfaces may change. This release targets the exact 0.1.0-rc.6 DSH package line.

简体中文

What it provides

• Repository status, staged/unstaged diffs, history, and local branches
• Stage, unstage, safe restore, commit, branch create/switch/safe-delete
• Fetch, fast-forward pull by default, and push without force options
• GitHub pull requests: list, view, create, edit, checkout, merge, and comment
• A DSH Web sidebar panel for changes, text-file editing, commits, branches, history, and pull requests
• Model-facing tools for the same workflows: git_status, git_diff, git_log, git_stage, git_commit, git_branch, git_sync, and github_pr

This project aims for Git/GitHub workflow parity with coding agents such as Codex. It does not claim to reproduce unrelated proprietary Codex features.

Requirements

• Node.js ^22.19.0 or >=24
• DeepSeek Harness 0.1.0-rc.6
• Git on PATH
• GitHub CLI on PATH and authenticated with gh auth login for pull-request features

The plugin never stores GitHub tokens. Authentication remains owned by Git and gh.

Install from GitHub

Until an npm release exists, install from a GitHub repository:

dsh plugin --profile web add github:FlutterSoul/dsh-git-workbench

Git-source installation runs this package's prepare build. pnpm 10 and later intentionally reject that on the first attempt. Review the repository, then copy the exact package key printed by DSH into $DSH_HOME/profiles/web/pnpm-workspace.yaml and retry. With pnpm 11.19 or later, the repository-scoped form is:

allowBuilds:
  'dsh-git-workbench@git+https://github.com/FlutterSoul/dsh-git-workbench.git': true

This grants build permission only to this Git repository; do not disable pnpm's build safeguards globally. For reproducible installations, append a trusted commit or tag to the GitHub specifier.

Start DSH Web:

dsh --profile web

The Git entry appears in the sidebar footer. It follows the current task's registered workspace.

Configuration

The bundle inserts the plugin with defaults through cordis.patch.yml. Configure its Loader entry in the DSH profile when non-default values are needed:

Option	Default	Purpose
gitBinary	git	Git executable
ghBinary	gh	GitHub CLI executable
commandTimeoutMs	120000	Per-process timeout
maxOutputBytes	4194304	Maximum captured command output
maxFileBytes	1048576	Maximum file size accepted by the editor
maxRequestBytes	2097152	Maximum Web API request body
defaultRemote	origin	Default fetch/pull/push remote
defaultPullMode	ff-only	ff-only, rebase, or merge
pushBeforePrCreate	true	Push the head before creating a PR
mutationApproval	all	Model-tool approval policy: all, destructive, or none
allowedRoots	[]	Additional absolute roots the browser UI may operate in

The UI accepts registered DSH workspaces by default. allowedRoots is for deployments that intentionally expose additional workspace trees.

Safety model

• Commands use spawn with shell: false; arguments are never concatenated into a shell command.
• Git and GitHub CLI interactive prompts and pagers are disabled.
• Mutations are serialized per repository.
• Model-initiated mutations request approval by default. A missing approval service fails closed.
• Browser calls require same-origin requests and are constrained to registered/configured workspaces.
• Text-file saves use an expected SHA-256 hash, preventing silent overwrite after concurrent edits.
• Force push, forced branch deletion, git clean, arbitrary Git arguments, and arbitrary gh arguments are not exposed.
• “Discard” only calls git restore --worktree for explicit tracked paths; it never deletes untracked files.

UI button clicks are direct user actions. The UI asks for confirmation before discard, branch deletion, and merge.

Development

pnpm install --ignore-scripts
pnpm check
pnpm pack --dry-run

For a local DSH profile:

dsh plugin --profile web add ./path/to/dsh-git-workbench
npx @deepseek-ai/dsh web

The test suite creates disposable Git repositories and does not contact GitHub. Live PR verification requires a repository and authenticated gh account under your control.

Architecture

DSH agent tools ─┐
                 ├─ GitWorkbench ── git / gh child processes
DSH Web panel ─ API ┘
       │
       └─ sidebar.footer.action client slot

src/git.ts owns all Git/GitHub operations and path validation. src/tools.ts is the model-facing adapter. src/api.ts is the constrained same-origin Web adapter. src/client/ contains the sidebar UI.

Scope and limitations

• Text editing is UTF-8 only. Binary files and files over maxFileBytes remain diff-only.
• GitHub operations currently use GitHub CLI and GitHub-hosted pull requests; other forges are not implemented.
• Conflict resolution is shown through status and file editing, but no semantic merge editor is included.
• The plugin does not create repositories, rewrite history, manage credentials, or bypass branch protection.
