dsh-git-manager

English | 中文

A GitHub-connected visual git manager for DeepSeek Harness — guided GitHub-Flow steps, commit graph with PR/CI badges, one-click GitHub login, and structured git tools for the agent.

Its panel chrome is built the way dsh-better-sidebar builds its own: every color, type role and motion value rides a DSH theme token, the chrome is flat (hairlines and hover fills, no shadows in the flow), and icon-only controls are round and transparent until hovered. Light/dark and any dsh-web-ui skin re-skin the panel for free — the panel contains no palette of its own and no theme selector. See DESIGN.md.

Renamed from gitcompass in 2.0.0. The package, the plugin row id (dsh-git-manager), the HTTP routes (/gitm/*) and the CSS surface (--gm-*) all moved together. The model-facing tool names (git_status, git_commit, github_pr_*, …) are deliberately unchanged — they name the operation, not the product.

Features

• Guided Flow Strip (top bar): visual step indicator through the GitHub-Flow stages: Branch → Commit → Push → PR → Review → Merge.
• Branch Management: view local/remote branches, switch, create, delete, rename, merge, fetch, checkout remote.
• Changes View: file status (staged/unstaged/untracked), stage/unstage, commit, diff viewer (click any file to see changes), stash/pop, push, pull, fetch.
• Commit Graph (GitLens-style lane visualization): 3-column layout (lane / SHA / subject), PR badges, cherry-pick to current, revert commit.
• PR Management: list PRs, view detail (checks, reviews, comments), create PR, squash merge, review (Approve / Request Changes / Comment), add comment.
• Issues: list issues, view detail, create new issue, add comment.
• GitHub Integration: device-flow OAuth login, PAT input, gh CLI reuse, encrypted token storage (DPAPI on Windows).
• Structured Git Tools (model-side): git_status, git_diff, git_branches, git_commit, git_push, github_pr_list/read/create/merge/comment/review, github_issue_list/read/create/comment.
• Agent Activity Monitor: a live SSE feed of every agent tool call (start/completion/failure); a repo observer polls workspace state to surface bash git operations performed outside the plugin's tools (new commits / branch switches / working-tree changes).
• In-Panel Approvals (panel-authoritative): write operations pop an approval card inside the panel where you can Approve or Reject directly; races the native DSH modal — first decision wins. The native channel's automatic rejection (including the ghost deny under approval policy never, e.g. the danger-full-access preset) cannot veto the panel card — the panel approval path works under any approval policy. Panel decisions are one-shot and memory-only; with no panel connected the call fails fast with a hint to open the panel (or pre-approve the tool there), instead of silently hanging for 5 minutes.
• i18n: auto-follows the DSH Web locale (Chinese / English).
• Theme: no palette of its own — follows the host theme tokens, so light/dark and third-party skins both apply.
• Two host modes: when dsh-better-sidebar is installed the panel contributes itself as one of its sidebar tabs and gives up its own column to it; without it the panel keeps its standalone right-column card, now collapsible. See below.

Install

dsh plugin --profile web add dsh-git-manager

Or for local development:

dsh plugin --profile web add link:/path/to/dsh-git-manager

Restart dsh web, open a session bound to a git repository, and the "Git Manager" panel appears in the right-side column.

Host modes

The plugin never claims a surface the host already owns:

• dsh-better-sidebar present — the panel registers a sidebar tab (dsh-git-manager:panel, titled "Git Manager" / "Git 管理", idempotent) and does not mount its own column. You open it from the sidebar's new-tab list; it then persists with the session. The tab carries a live badge with the number of write operations waiting for your approval.
• dsh-better-sidebar absent — the panel keeps its own right-column card, with a collapse handle in its header. Collapsing leaves just that header strip and stops all polling (nothing hits git in the background); the state persists.

The detection is a runtime probe (ctx.get('betterSidebar')), so better-sidebar stays an optional peer: no hard dependency, no build-time import of its types, and a failed registration degrades to the standalone card instead of losing the panel. It can be overruled with localStorage['gm.host'] = 'dock' | 'tab' (default: auto).

The panel also follows the session's workspace: it resolves the cwd of the session it belongs to (the tab's scope.cwd, else the active session), and re-selects the repository whenever you switch sessions — adding it to the list first if it was never seen (the host walks up to the innermost repository root, so a session sitting in a nested repo gets that repo rather than the workspace containing it). A repository you picked by hand is never overridden.

What counts as "the folder I am working in"

A session workspace is often only a container — D:\Harness holds a dozen independent repositories — so following the session cwd alone can never tell you which one you are actually editing. The host therefore also watches tools/execute: it reads the path arguments of the file tools (read, write, edit, grep, glob, …), walks up to the enclosing repository root, and auto-registers that repository into the picker. A file that does not exist yet counts too — the observation happens before the tool runs, so a write creating a new file is exactly the case that matters.

• Auto entries are marked and shown as name · auto in the picker, so a shelf that grows by itself stays visible instead of mysterious.
• They are capped at 20; the oldest auto entry is evicted first, and hand-added repositories are never touched.
• repo:auto-added is emitted on the activity stream each time one lands.
• Turn it off with config.autoRegisterRepos: false on the plugin row — the strip below still reports what is being touched.

A two-line strip under the repo picker is always visible and answers both questions at a glance:

Session folder   D:\Harness
Editing          D:\Harness\dsh-learn-wiki

The first line is the session folder the panel follows; the second is the folder the agent is touching right now (Editing for writing tools, Reading for read-only ones). When the second one is a known repository that is not currently selected, a Switch button appears beside it.
