A Git panel for the DSH Web UI: one Git icon in the left rail, one full-page panel that shows every registered workspace at a glance and gives a single repository three views (changes / history / branches). It never switches branches behind your back, never force-pushes, and never stages anything silently — every destructive action asks you twice.
Overview: one card per workspace, with branch/upstream sync, change counts and an AI one-liner
/status, /diff, /log, … only runs git commands that cannot write the repository (GIT_OPTIONAL_LOCKS=0).fetch --prune, pull --ff-only, push) and a small, explicit set of local writes, all behind one guard rail (POST /action)..git over SSE and refreshes the moment a commit, branch switch, fetch or push lands.ctx.gitPanel and as three model tools (git_status, git_diff, git_commit_message).The package is a DSH bundle plugin (a profile assembly layer). Three ways in:
① Into a profile (survives restarts) — register the package and its config in the profile's cordis.patch.yml:
- id: git-panel
name: '@dsh-external/dsh-git-panel'
config:
aiCommitProvider: minimax-cn
aiCommitModel: MiniMax-M3.1-Flash-Preview
aiCommitReasoningEffort: low
Then make the package part of dsh.profile.bundles (or npm i it into the profile directory). The plugin ships its own cordis.patch.yml, which inserts the loader row — that row can only come from the bundle's own patch file, and without it the routes and the rail icon disappear on the next profile re-assembly or restart (see Notable design decisions).
② Live injection (handiest while developing) — no restart, no profile edit:
dev_install_package { "dir": "/path/to/dsh-git-panel" } # first install
dev_reload_package { "packageName": "dsh-git-panel" } # after changing host code
dev_install_package skips an entry that already exists, so host-code changes need dev_reload_package (it clears the loader cache and rebuilds the fiber). Client-only changes need neither: npm run build:client and a page refresh.
③ Build from source — scripts/build.sh links every build dependency (cordis, schemastery, react, @types/node, @deepseek-ai/dsh-tools, tsdown) straight out of the checkout, so a clean clone needs no npm i:
git clone git@github.com:kolawong/dsh-git-panel.git
cd dsh-git-panel
DSH_CHECKOUT=/path/to/deepseek-harness npm run build:all # host tsc + client bundle
⚠️ After touching
src/client/**you must runnpm run build:client(orbuild:all).scripts/build.shonly compiles the host and type-checks the client — it does not bundlelib/client.js, so the type check passes while the browser still loads the previous UI.
Requirements: Node ≥ 20, git on PATH, and a DSH checkout for DSH_CHECKOUT (peer dependencies cordis, schemastery and react are provided by the host).

One card per registered workspace, dirty ones first:
↑ahead ↓behind, the change tally (staged · changed · untracked · conflicted) and the workspace path.N / M workspaces.全部 Fetch (N) fetches every repository that has an upstream, one at a time, with per-card progress; ● 实时 / ● 轮询 shows which update mode is live.Changes: branch, upstream and ahead/behind; the changed-file list grouped into conflicted / staged / changed / untracked; per-file unified diff; the commit box (with ✨ AI write message); a 贮藏 (stash) action; and the repository's stash list at the bottom.
History: a graph-drawn commit list — every commit is one row with its own lane and merge curves (SVG), ref labels (HEAD ->, tag:, origin/*), author and relative time. Grouped by calendar day (today / yesterday / last 7 days / earlier), with range / author / subject / path filters, infinite "load earlier commits" paging (HISTORY_PAGE = 50), and a commit detail pane on the right that reuses the same diff renderer. Merge commits get compare ^1 / ^2 buttons, because git show <merge> prints no patch at all.
Branches: local branches, newest tip first, current branch on top with a HEAD badge, upstream + [ahead/behind], tip hash/time/subject. 看历史 hands a branch to the history view. Branch switching and checkout -b are available and both ask for confirmation.
src/client/diff.ts parses unified diffs into a line model and the renderer draws them the way the official pages do:
diff --git, index, ---, +++, mode, rename) are not rows — the panel title already names the file and shows +28 −2.⋯ 74 lines not shown chip; clicking it fetches that range from the host (GET /context, ≤ 400 lines) and splices it back as ordinary context lines.Current → Longest lights up only Curren / Longes).159 chars chip sits outside the text span so it survives clipping.// or line-leading # comments. A toggle in the diff header turns it off completely.diff --cc) for conflicted files: two prefix columns per line, result-side line numbers only.All local writes go through one POST /action route with the same guard rails (custom header + JSON, workspace allow-list, one action per repository at a time, argv allow-list, child processes bound to the plugin lifecycle).
| Action | Command | Notes |
|---|---|---|
stage | git add -- <paths…> | 全部暂存 passes paths: ['.']; paths are mandatory — there is no "no paths means everything" |
unstage | git reset -q HEAD -- <paths…> | Falls back to git rm --cached -r --quiet -- <paths…> before the first commit |
discard | git checkout -- <paths…> | Destructive, needs confirm: true; discards worktree-vs-index, so staged content survives |
stash | git stash push --include-untracked --message "dsh-git-panel: <ISO>" | Destructive, needs confirm: true; includes untracked files |
commit | git add -- <paths…> (optional) → git commit -m <message> | Message required (≤ 4000 chars); hooks run normally (never --no-verify) |
stashApply / stashPop / stashDrop | git stash apply/pop/drop <ref> | ref must be the listed stash@{N}; drop needs confirm: true |
continueOperation / abortOperation | git commit --no-edit (merge) or git -c core.editor=true <op> --continue / git <op> --abort | Refuses to continue while conflicts remain; abort needs confirm: true |
checkout | git checkout <ref> / git checkout -b <name> | Branch names go through safeRef; needs confirm: true |
Remote actions: fetch (git fetch --prune), pull (fetch then pull --ff-only), push (git push, needs confirm: true or 428). The argv never contains --force, --tags or --set-upstream. A push is never one click: the button first arms a "confirm push → origin/main" state for 8 seconds.
Everything lands in an in-panel action log at the bottom of the screen: timestamp, each command, exit code, duration and the git output tail.
GET /status reports operation: {kind: merge|cherry-pick|revert|rebase, unmerged: N} | null. When one is running, the changes view grows a banner with two honest ways out (完成合并 / 继续… and 中止…), and conflicted files render as combined diffs. The verbs come from the host, not from a guess: with nothing in progress the panel says so.
追溯 runs git blame --line-porcelain HEAD -- <path> and shows one label per contiguous attribution run; uncommitted files 404 and untracked files get a disabled button with the reason.对比…: arm it, click another commit, and the detail becomes a range read (git diff <base> <commit>) with the same renderer. base and parent are mutually exclusive (400).✨ AI write message drafts a commit message into the box, streaming token by token (POST /commit-message/stream, SSE frames begin → delta → done/error). While it streams the button becomes 停止, which also aborts the model call. The endpoint is a same-origin POST with the panel's custom header, so a stray page cannot spend your tokens.
git commit records), otherwise the whole work tree — and the UI says so. Untracked files and unstaged changes are listed separately as "will not be part of this commit".POST /prefs). With no settings service it falls back to localStorage and reports persisted: false.One model call writes a one-line "what is this project" for every workspace on the overview:
package.json description, the first 400 characters of the README, the last three commit subjects.~/.dsh/git-panel/summaries.json (override with DSH_GIT_PANEL_SUMMARY_STORE). The cache key is a sha1 fingerprint of exactly the signals that wrote it — provider, model, title, description, README, commit subjects — so a busy repository costs a rewrite of its own line while quiet ones are answered from disk. The first ask after a reload is already cached: true.error + failed: N alongside them) and only the projects that truly have no line stay empty; a failure with nothing stored at all is an honest 502 (504 on timeout). The panel therefore never blanks the cards it already had — a missing line reads 简介暂不可用 with the reason in its tooltip instead of a shimmer that never ends.force: true rewrites everything. Workspaces that left the registry are pruned from the store.The panel subscribes instead of polling: opening it starts one SSE stream per visible repository (GET /events?dir=…), and the host watches that repository's .git (itself + refs recursively + logs recursively) with fs.watch.
objects/, *.lock, gc.*, maintenance, COMMIT_EDITMSG, tmp_* are dropped — one fetch writes hundreds of objects, and forwarding those would turn a fetch into a refresh storm..git/HEAD and refs/heads/x changing together produce one refresh.● 实时 / ● 轮询 says which mode is active (data-live for automation).fs.watch cannot see an unstaged edit (it touches neither the index nor refs), and watching whole trees recursively would cost node_modules-scale overhead. Polling and window-focus refresh cover that case.| Field | Default | Purpose |

aiCommitProvider, aiCommitModel and aiCommitReasoningEffort are volatile: the settings service can rewrite them live (that is how the picker remembers a model across browsers).
All routes live under /api/git-panel. dir is always validated against the workspace registry before any git command runs (403 otherwise).
| Route | Purpose |
|---|---|
GET /overview | One card's data per registered workspace (two git commands per repository, overviewConcurrency at a time; an unreadable workspace degrades to an "unavailable" card) |
GET /status?dir= | Branch/upstream/ahead-behind + file list + line counts + operation |
GET /diff?dir=&path=&staged=&untracked=&hash=&parent=&base= | One file's unified diff (worktree, index, a commit, a merge parent, or a range) |
GET /context?dir=&path=&staged=&untracked=&hash=&start=&count= | Unchanged lines for expanding a diff gap (start ≥ 1, 1 ≤ count ≤ 400; missing / binary flags) |
GET /log?dir=&limit=&skip=&all=&ref=&path=&author=&grep= | Commit history, newest first, --topo-order; limit 1..200, skip 0..100000 |
GET /branches?dir= | Local branches (newest tip first, current first) with upstream/track/date/subject |
GET /show?dir=&hash=&parent=&base= | One commit's metadata and touched files |
GET /stashes?dir= | Stash list (newest first) |
GET /blame?dir=&path= | Per-line attribution (git blame --line-porcelain HEAD) |
GET /models | Provider routes and their advertised models (5-minute host cache) + remembered |
GET /events?dir=…&dir=… | SSE: a hello frame describing what is watched, then one debounced change frame per repository; comment-only heartbeats when idle (≤ 64 dirs) |
POST /action | {dir, action, confirm?, paths?, message?, ref?} — every remote and local write |
POST /commit-message | {dir, staged?, provider?, model?, reasoningEffort?} — one draft (read-only: it never touches the index) |
POST /commit-message/stream | The same draft as SSE frames |
POST /prefs | — remember the draft model via the settings service |
Write routes require content-type: application/json and the x-dsh-git-panel header (a cross-origin form cannot set it). Read routes time out with 504; actions time out with 504 without being killed by the browser disconnecting (they are bound to the plugin lifecycle, not the request). One action per repository at a time (409).
Other plugins can inject the read path as a service:
interface GitPanelService {
overview(): Promise<{ ok: true; entries: OverviewEntry[] }>
status(dir: string, lineCounts?: boolean): Promise<StatusPayload>
diff(dir: string, target: { path: string; staged?: boolean; untracked?: boolean; hash?: string }): Promise<string>
log(dir: string, limit?: number): Promise<CommitEntry[]>
show(dir: string, hash: string): Promise<{ commit: CommitEntry | null; files: CommitFile[] }>
}
The service is read-only on purpose: write operations are deliberately not exposed, because there is no human finger behind a service call and those operations destroy uncommitted work. Every dir still goes through the workspace allow-list.
Three model tools are registered (through ctx.inject(['tools']), so a profile without a tools service still loads the panel):
| Tool | Arguments | Notes |
|---|---|---|
git_status | dir? (default: all workspaces), line_counts? | Without dir: branch/upstream/ahead-behind/counts per workspace. With dir: repo + counts + the file list |
git_diff | dir, path, staged?, untracked?, hash?, max_lines? | Unified diff lines, truncated to 400 by default (1..2000) with explicit total_lines / truncated / note |
git_commit_message | dir, staged?, provider?, model? | Text only — it never stages, commits or pushes, and says what one model call costs |
dir is checked against workspaceRegistry.list() before any git command runs (403 outside it). Paths may not be absolute and may not contain .. (400).GIT_TERMINAL_PROMPT=0, GIT_CONFIG_COUNT=0, GIT_OPTIONAL_LOCKS=0, LC_ALL=C), a per-command deadline and a bounded stdout cap.confirm: true, and allowRepoWrites / allowPush can switch whole groups off.GIT_OPTIONAL_LOCKS=0 also stops the panel from writing .git/index and triggering its own watcher).npm run build:all # scripts/build.sh + npm run build:client
DSH_CHECKOUT=/path/to/deepseek-harness bash scripts/build.sh # host tsc + client type check only
npm run build:client # tsdown → lib/client.js
node scripts/smoke.mjs # host smoke: real git, real routes (328 assertions)
node scripts/diff-test.mjs # client pure logic on real git diff output (115 assertions)
node scripts/live-check.mjs # against a running harness, real requests (112 assertions)
node scripts/visual-check.mjs # real Chromium end-to-end + screenshots (141 assertions)
node scripts/rail-check.mjs # "is the Git icon there and does it open?" (4 assertions)
node scripts/readme-shots.mjs # regenerate docs/*.jpg for this README
visual-check.mjs, rail-check.mjs and readme-shots.mjs resolve Playwright and its chromium from the harness checkout and ~/.cache/ms-playwright; if either is missing they print SKIP and exit 0 so they never break a plain test run. They read the profile's login credentials only to drive the login form — nothing is printed or written to disk.
| File | Responsibility |
|---|---|
src/index.ts | Host half: the /api/git-panel/* routes, SSE, fs.watch, ctx.subprocess, path/ref/parent validation, the write guard rails, the AI calls and the summary store |
src/client/index.ts | Client half: two slot registrations (main + sidebar.panellist) |
src/client/panel.tsx | The page: overview / repository (changes · history · branches), commit box and model picker, diff rendering |
src/client/styles.ts | Injected design system (one <style> element, removed on unload) — hover/focus/transitions that inline styles cannot express |
src/client/icons.tsx | The whole 16×16 line-art icon set (no emoji, no font glyphs) |
src/client/diff.ts | Pure logic: unified diff → line model, intra-line diff, rewrite pairing |
src/client/graph.ts | Pure logic: commit list → lane layout (buildGraph / graphWidth) |
src/client/highlight.ts | Pure logic: conservative tokenizer + intra-line marker overlay |
src/client/queue.ts | Pure logic: sequential execution with progress reporting |
src/client/api.ts | The JSON contract with the host and the fetch helpers |
cordis.patch.yml | The bundle patch that inserts the loader row |
cordis.patch.yml (declared as dsh.bundle.patch). This package once shipped without it: runtime injection made everything look fine until the profile was re-assembled, at which point host routes 404'd and the rail icon vanished while dsh.profile.bundles still listed the package. smoke.mjs now guards that contract with four assertions, and rail-check.mjs answers "is the icon there?" in seconds with a real browser.lib/client.js is produced by tsdown, not by tsc, which is why scripts/build.sh cannot cover it.color-mix derives the rest, and the visual suite asserts that no literal colour creeps back in.409 is cheaper than two git adds racing each other.pull is --ff-only. The panel refuses to invent merge commits; if the branch diverged, git's own refusal is shown verbatim.<button> needs background: transparent. The UA's buttonface paints a grey block over rows — that is what "the whole file list looks selected in dark mode" was.--dsw-specific-sidebar-fill) and a border-l2 separator — border-l1 is too faint to read as a boundary.Cards show 简介暂不可用 / the AI one-liner never appears.
The summary route reports why: POST /api/git-panel/project-summaries answers error + failed: N when the batch call failed, and the stored lines still come back. The usual cause is the model call itself being rejected — for example MiniMax's MiniMax-M3.1-Flash-Preview now requires adaptive thinking and returns 400 … requires adaptive thinking (2013) when the request disables thinking. Two fixes:
# Option A — tell this plugin's calls to think:
aiCommitReasoningEffort: low
# Option B (deeper, also fixes the agent's own calls to that route) — under the
# llm-pi-ai provider config, drop the `off` declaration so no request ever sends
# thinking.type=disabled for that model:
- id: llm-pi-ai
config:
providers:
minimax-cn:
models:
- id: MiniMax-M3.1-Flash-Preview
reasoningEfforts: { low: low, medium: medium, high: high, max: max }
Note the asymmetry that makes this easy to get wrong: an empty aiCommitReasoningEffort omits the option (the model/route decides), while the literal off requests that thinking be disabled — and some routes refuse that outright.
The icon and the routes disappeared after a restart. The bundle patch row is missing (see above) — check that cordis.patch.yml is present and that package.json still declares dsh.bundle.patch.
TS7006: Parameter 'args' implicitly has an 'any' type when building from a fresh clone. The build could not resolve @deepseek-ai/dsh-tools, so defineTool's callbacks lost their contextual types. scripts/build.sh links that package (and every other build dependency) from DSH_CHECKOUT; make sure DSH_CHECKOUT points at a built DSH checkout.
The panel shows the old UI after a client change. lib/client.js was not rebuilt: run npm run build:client and refresh.
The panel fell back to ● 轮询. /events could not start (watching disabled, inotify limits, unsupported backend) — the panel keeps working at 15 s / 20 s polling; see the host logs for the reason.
