Adds `getCommitContext()`, which gathers the changes a commit message should describe. Part 1 of 4 for AI commit-message generation; nothing consumes it yet. Staged changes are collected first, since that is what a commit will actually contain. When nothing is staged it falls back to the working tree so callers still have something to summarize before staging. The fallback reads `git status --short` rather than a diff because untracked files appear in no diff and would otherwise be invisible. The fallback deliberately runs `git diff` rather than `git diff HEAD`: the index is known to be empty at that point so the output is identical, but `HEAD` does not resolve in a repository without an initial commit, where it would fail. Reuses the existing `checkGitInstalled`, `checkGitRepo`, and `truncateOutput` helpers. `maxBuffer` is raised past Node's 1MB `exec` default, which real diffs routinely exceed.

Part 2 of 4 for AI commit-message generation. Adds the model-facing half: a customizable prompt and a service that turns git context into a message. No command or UI wires it up yet. - Registers COMMIT_MESSAGE in `support-prompt.ts` alongside ENHANCE. Because the Prompts settings tab iterates the support-prompt registry, this gives the template an editor and a reset button without any new UI code. The default asks for Conventional Commits and tells the model to account for every changed file; without that instruction models describe the largest file and silently drop the rest. - Adds `commitMessageApiConfigId` so a small, fast profile can be used for this task. Mirrors `enhancementApiConfigId`, including the `listApiConfigMeta` guard before `getProfile()` so a deleted profile falls back to the active configuration rather than throwing. - Adds `generateCommitMessage()`, which resolves the repository from the git extension API, collects context, and writes the cleaned result into the SCM input box. Models wrap answers in fences and quotes despite instruction, so the response is stripped before use. Progress is reported at `ProgressLocation.Window`; `SourceControl` drops the title, and no location renders a cancel button that would work, since nearly every provider ignores `completePrompt`'s abort signal.

Part 3 of 4 for AI commit-message generation. Wires the generator to a button
in the Source Control title bar, making the feature reachable for the first
time.
The command receives the clicked `SourceControl`, which lets the generator pick
the right repository in a multi-root workspace. It resolves the provider from
`registerCommands` rather than the visible instance, so the button works while
the Zoo Code sidebar is closed.
The icon is the existing zebra mark, reusing the `panel_light`/`panel_dark` pair
already shipped for the tab icon. That required widening `commandsSchema.icon`
in `packages/build`: it accepted only a codicon string, so a themed
{light, dark} pair would have thrown in `contributesSchema.parse()` during the
nightly manifest build. That path only runs under `vsix:nightly`, so the failure
would not have surfaced in normal development.

📝 WalkthroughWalkthroughThe extension adds an SCM command that generates commit messages from staged or working-tree changes. It resolves the Git repository, uses a configured provider, writes the generated message to the SCM input, and adds related settings, prompt definitions, tests, and localization.

Add state-propagation coverage.
This cohort adds no focused ClineProvider test for commitMessageApiConfigId. Add a getStateToPostToWebview() test with a configured profile ID and with the setting unset. This protects the saved selection and the unset fallback.
As per coding guidelines, “Add focused tests for … the value returned by getStateToPostToWebview().”

Preserve existing SCM input before writing the generated message.
Line 127 replaces a nonempty commit draft. It also replaces edits made while the completion request is pending. Define the nonempty-input behavior and preserve user edits. Append the generated message, prompt before replacement, or replace only when the value still equals the captured initial value. Add tests for a nonempty draft and for an edit during generation.
The PR objective requires defined behavior for existing input text.

Treat Git context as untrusted data.
Line 255 appends repository-controlled diff text after the prompt instructions. A changed file can contain instruction-like text that causes the model to ignore the required commit-message format.
State that Git context is data only. Delimit it before interpolation.

Apply a final character limit to commit context.
Lines 387 and 403 limit only the number of lines. A one-line generated or minified diff can still produce a prompt near the 10 MB buffer limit from Line 380. This can exceed provider context limits and make commit-message generation fail.
Pass a character limit to truncateOutput() at both call sites. Add a regression test with one oversized line.

What should happen when the clicked root has no match, or when multiple repositories exist without a supplied target? Would returning no repository be safer than silently operating on repositories[0]?

Description
Wires the generator to a button in the Source Control title bar. This is the PR where
the feature becomes reachable: click the Zoo Code icon next to the commit box and a
message appears in it.
Repository resolution. The
scm/titlemenu passes the clickedSourceControl,whose
rootUriis matched against the git extension's repository list. That is whatmakes the button correct in a multi-root workspace rather than always targeting the
first repository. Falls back to the first repository when no match is found.
Uses the registered provider, not the visible one.
getVisibleProviderOrLogwouldreturn nothing when the Zoo Code sidebar is closed — which is the common case when
someone is working in the Source Control panel. The command takes the provider passed
into
registerCommandsinstead, so the button works regardless of sidebar state.The icon reuses the existing zebra mark (
panel_light.png/panel_dark.png),already shipped for the tab icon, so no new art is added.
One change outside the feature. That themed icon forced a fix in
packages/build:commandsSchema.iconwas declaredz.string().optional(), accepting only a codiconstring. A
{light, dark}pair would have thrown incontributesSchema.parse()duringthe nightly manifest build. Worth flagging because that path only runs under
vsix:nightly— the failure would not appear in normal development or in most CI runs,and would have surfaced as a broken nightly.
Test Procedure
src/activate/__tests__/registerCommands.spec.tsgains a test asserting the commandforwards the clicked
SourceControlto the generator and uses the registered providerrather than the visible instance.
Packaging verified with
pnpm --filter ./src vsix, then the resulting VSIX inspected toconfirm both icon files ship at the paths the manifest references and that the packaged
contributesblock contains the command and thescm/titlemenu entry. That is thecheck that would have caught the
packages/buildschema problem.Manual verification in a scratch repository:
dark themes.
Local checks:
pnpm lint,pnpm check-types(11/11 packages), fullsrcsuite(7389 passed, 37 skipped),
node scripts/find-missing-translations.js,pnpm knip.Pre-Submission Checklist
Visual Snapshots
The new UI is a VS Code menu contribution, not a webview component, so the Playwright CT
harness cannot capture it —
webview-uisnapshots only cover the webview. Screenshotbelow is a review aid.
Generated message in the commit input box. Four files staged across three concerns;
note
test.pyis called out as unrelated rather than forced underfeat(auth):Note
Screenshot to be attached.
Documentation Updates
This is the PR that makes the feature visible, so the docs repo will want a short page
on the Source Control button.
Additional Notes
Aligns with the roadmap's Enhanced User Experience goal — it removes a small,
repeated friction point and gives Zoo Code a presence in a panel where it previously had
none.
