Closes: #290

Part of: #145 · Stack 2 of 4 · Depends on #1227 · Replaces the all-in-one #1218

Description

Adds the model-facing half of commit-message generation: a customizable prompt, a
dedicated model setting, and the service that turns git context into a message. Still
no command or picker UI, so nothing is reachable by a user yet.

The prompt is editable, for free. COMMIT_MESSAGE is registered in
support-prompt.ts alongside ENHANCE. The Prompts settings tab iterates the
support-prompt registry, so the template immediately gets a textarea, a reset button,
and customSupportPrompts persistence with no new UI code — which is why #290 is
closed here rather than in stack 4.

The default prompt tells the model to account for every changed file. That
instruction is load bearing rather than decorative. Without it, a model given four
staged files across three concerns will confidently describe the largest one and
silently drop the rest. Observed repeatedly in testing before the wording was added.

commitMessageApiConfigId mirrors enhancementApiConfigId exactly, including the
listApiConfigMeta.find(...) guard before getProfile() — that call throws on an
unknown id, so a profile deleted after being selected must fall back to the active
configuration rather than break the button.

Response cleanup. Models wrap answers in code fences and quotes despite being told
not to, so the result is stripped before use.

Progress is reported at ProgressLocation.Window. SourceControl was the obvious
choice but silently drops the title, leaving an unlabelled spinner. No location renders
a cancel button that would do anything useful — see Additional Notes.

Test Procedure

src/services/commit-message/__tests__/generateCommitMessage.spec.ts covers: writing
the cleaned message to the input box, fence/quote stripping, using the dedicated
profile when configured, falling back when the configured profile no longer exists,
selecting the right repository from SourceControl.rootUri in a multi-root workspace,
the no-changes path leaving the input box untouched, the missing-git-extension path,
and generation failures surfacing rather than throwing.

Also asserts progress is reported at a location that actually renders the title, so a
regression back to SourceControl cannot silently produce an unlabelled spinner.

Translations for all 17 locales are included for the new keys, not left as English
fallbacks — find-missing-translations.js gates on this.

Local checks: pnpm lint, pnpm check-types (11/11 packages), full src suite
(7388 passed, 37 skipped), node scripts/find-missing-translations.js.

Pre-Submission Checklist

  • Issue Linked: This PR is linked to an approved GitHub Issue (see "Related GitHub Issue" above).
  • Scope: My changes are focused on the linked issue (one major feature/fix per PR).
  • Self-Review: I have performed a thorough self-review of my code.
  • Testing: New and/or updated tests have been added to cover my changes (if applicable).
  • Visual Snapshot (UI changes only): not applicable — see below.
  • Documentation Impact: I have considered if my changes require documentation updates.
  • Contribution Guidelines: I have read and agree to the Contributor Guidelines.

Visual Snapshots

No new UI components. The Prompts tab gains a "Commit Message" entry, but it is
rendered by the existing support-prompt UI rather than by any code in this PR, so there
is no new surface to snapshot.

Documentation Updates

  • No documentation updates are required.
  • Yes, documentation updates are required.

The editable commit-message prompt and the model setting are both user-facing. Happy to
open a docs PR once the stack is accepted.

Additional Notes

No cancel button, so #289 stays open after this stack. Only
ProgressLocation.Notification renders one, and a toast on every commit would be
intrusive. It would also be inert: completePrompt accepts an abortSignal, but 24 of
25 providers ignore the options argument entirely, so the request cannot actually be
interrupted today. Making cancellation real needs a provider-layer change, which felt
out of scope here — but it is worth knowing that gap exists.

On latency, since it will be the first thing users notice: git collection measures
~120 ms and the prompt is ~600 tokens on a small repo. The wait is the model. A
reasoning-heavy local model spends far longer thinking than the rest of the flow takes,
which is exactly why the dedicated profile setting is in this PR rather than deferred.

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Mergeability Score: 🟡 Moderate · up to 44d0e

This change adds commit-message generation that sends repository-derived context to the configured model. An unresolved symbolic-link handling issue could disclose content outside the repository, so the PR is not merge-ready until that risk is addressed.

Cover getProfile rejection and preserve the active configuration.

This test only covers an ID absent from listApiConfigMeta. It never calls getProfile.

If listApiConfigMeta contains the ID and getProfile rejects, generateCommitMessage enters its outer catch. It shows an error instead of using apiConfiguration.

Add a test that keeps "config2" in metadata and makes getProfile reject. Update the generator to retain the active configuration when that lookup fails.

As per coding guidelines: “Prefer the narrowest test layer that proves behavior.”

Preserve the active-profile fallback when getProfile() fails.

Line 102 can throw after the cached metadata check succeeds. This occurs when the profile is deleted or metadata is stale. The outer catch then stops generation instead of using apiConfiguration.

Catch the profile lookup failure in this block and retain configToUse. Add a test where listApiConfigMeta contains the ID but getProfile() rejects.

Proposed fix
 if (commitMessageApiConfigId && listApiConfigMeta?.find(({ id }) => id === commitMessageApiConfigId)) {
-	const { name: _, ...providerSettings } = await provider.providerSettingsManager.getProfile({
-		id: commitMessageApiConfigId,

four tests covering set and unset across both getState() and getStateToPostToWebview(), in the ClineProvider spec next to the existing state coverage

Rafael-Silva-Oliveira and others added 2 commits August 13, 2026 12:24
Adds `getCommitContext()`, which gathers the changes a commit message should
describe. Part 1 of 4 for AI commit-message generation; nothing consumes it yet.

Every command runs through `execFile` with an argument array, so no path is ever
interpolated into a shell string, and both listings are read NUL-delimited:
`git diff --cached --name-status -z` for the index and
`git status --porcelain=v1 -z --untracked-files=all` for the working tree. Their
rename records disagree on field order - the diff form emits the original path
first, porcelain the new one - so each has its own parser. Copy records carry two
paths as well and appear whenever `diff.renames = copies` is configured, so they
are consumed correctly even though copy detection is never requested; reading one
path where there are two would shift every later record onto the wrong file.

The result is a typed `CommitContextResult` rather than a string. Failures that
are expected rather than exceptional - an oversized diff exceeding `maxBuffer`, a
repository git refuses to describe - come back as a reason, so the function never
rejects. Branch and recent subjects are collected as context, and tolerate the
unborn-HEAD case where `git log` fails outright.

Untracked files have no diff, so a bounded head of each one is read directly:
without it an untracked-only change reaches the model as a bare list of
filenames. Only the first 2KB of each file is read, so an enormous file costs
nothing, and anything containing a NUL byte is skipped as binary.

Output is capped by characters as well as lines. A line limit alone is not a
bound - one minified or generated file can be a single line of several megabytes.

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. That 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.

Test provider failure propagation.

The PR objective includes provider-failure coverage. Add a test that rejects singleCompletionHandler and asserts that generateCommitMessage rejects with the same error. Keep the rejected provider call and assertion inline.

As per coding guidelines, “Keep provider-specific payloads, failure streams, and assertions inline when they clarify the behavior under test.”

Document the unavoidable double assertions.

Add nearby comments explaining why each as unknown as cast is safe, including the mocked callback or partial FileHandle shapes. Replace these casts with typed adapters or helpers when practical. Apply the same explanation to the partial ClineProvider test fixture.

Comment thread src/shared/__tests__/support-prompts.spec.ts
Falling back to the working tree meant the message could describe changes the
commit would not contain. An empty index now returns `nothing-staged`, which the
caller turns into advice to stage something, and `no-changes` is reserved for a
genuinely clean tree.

Removes the untracked-file reading that only the fallback needed.
Turns collected git context into a commit message. Part 2 of 4 for AI
commit-message generation; the VS Code wiring that calls this follows.

The prompt exposes the context as separate placeholders - `${branch}`,
`${recentCommits}`, `${changedFiles}` and `${diff}` - rather than one opaque
blob, so a user editing the prompt in Settings -> Prompts can reorder or drop any
of them independently. The diff is fenced in explicit markers and labelled as
repository content, since it reaches the model verbatim and can contain
instruction-like text.

`generator.ts` is deliberately free of VS Code: it takes git context and provider
settings and returns cleaned text, locating no repository and writing nowhere, so
it can be exercised without the extension host. Its tests load no `vscode` mock
at all, which is what keeps that honest.

An empty response is now a failure rather than a success. A model that answers
with nothing, or with an empty code fence, previously produced an empty message
that a caller would happily write over whatever the user had already typed.

`config.ts` resolves which profile to generate with. The chosen profile is only a
preference: a saved id outlives the profile it points at, and a profile can be
deleted between reading the state and looking it up, so both cases fall back to
the active configuration instead of stopping generation.
