CommitWright — AI Commit Messages (Claude CLI)

Commit messages from your staged diff. A ✨ button in VS Code's Source Control panel drafts your commit message with the Claude CLI you already have — on your existing subscription, no separate API key.

Stage your changes, click ✨, review the draft, commit. The message lands in the commit box as editable text — you always get the final word.

Why CommitWright

• Your subscription, no API key. It drives the official claude CLI you have already installed and logged into. Nothing else to sign up for.
• Zero telemetry of its own. The extension collects nothing and sends nothing anywhere — it only runs the local binary. Details in Privacy.
• Your style, your language. Four subject styles, subject-only or subject + body, and any output language — English, Russian, German… even Elvish.
• Works where you do. Six entry points plus a hotkey, each one can be switched off.

Quick start

1. Install the Claude Code CLI and log in: run claude in a terminal, then /login. CommitWright requires it.
2. Install CommitWright.
3. Open a Git repository, stage some changes, and click the ✨ button in the Source Control title bar — or press Ctrl+Alt+G (Cmd+Alt+G on macOS).

Windows tip: if claude is not on your PATH, point commitwright.cliPath at the executable with an absolute path.

How it works

CommitWright runs the official Anthropic CLI (claude) that you install and authorize yourself. On click it collects the diff, pipes it to claude -p together with a prompt, and inserts the reply into the commit message box. The extension never stores, extracts, or transmits your token — authentication stays entirely inside the official binary.

A few deliberate guardrails:

• The CLI runs with tools disabled and an isolated working directory: it cannot read your project beyond the diff it is given, and your project's own Claude configuration does not leak into the message.
• Lock files (package-lock.json, yarn.lock, …) are excluded from the diff automatically; very large diffs are truncated.
• Untracked files are included when generating from all changes, so brand-new files get described too.

Entry points

Run CommitWright: Configure Entry Points for a checkbox list of all of them, and use commitwright.position.scmTitle to pin the title button to the left or right edge.

Slash commands

Type / as the first character of the commit box to generate with a one-off override of your defaults — /conventional writes this one message in Conventional style, /body adds a body, /lang picks a language:

Commit editor button

If you commit with the full editor (COMMIT_EDITMSG tab), the same ✨ lives in its toolbar:

Billing

Change effective June 15, 2026: programmatic CLI calls (claude -p, which CommitWright uses) are billed against a separate monthly Agent SDK credit included in Claude subscriptions — not against your interactive chat limits. You activate the credit once in your Claude account settings; it renews monthly and does not roll over. When it runs out, generation stops with a clear error (or continues at standard API rates if you have enabled extra usage).

Commit-message generation is lightweight — a short diff in, a line or two out — so a plan's monthly credit typically covers hundreds of generations. It is not free and not unlimited, though: see Anthropic's pricing and the Help Center article Use the Claude Agent SDK with your Claude plan for current terms.

Tip: a commit message does not need a frontier model. Pick haiku or sonnet via CommitWright: Select Model — faster and cheaper than a top-tier default. effort already defaults to low for the same reason.

Privacy — what gets sent

The extension itself collects no telemetry and sends nothing anywhere. It starts one local process — the official claude binary — and reads back its output. Your token is never touched.

What goes into the prompt (and only to the CLI):

• the diff — staged or working changes, per diffSource;
• the changed file names, if includeChangedFiles is on (default);
• your extraInstructions / promptTemplate, if set.

claude is not a local model: it sends the prompt to Anthropic's servers, and processing happens under the terms of your subscription. On consumer plans (Free/Pro/Max) the diff content may be used for model training if the "Model Training" toggle in your Claude privacy settings is on. Working with confidential code? Turn that toggle off — or use an API key: under commercial terms, training is off by default.

Where this stands with Anthropic's terms

Driving the official CLI on your own subscription is a pattern Anthropic itself ships: the official claude-code-action does it, and the headless docs show git diff | claude -p pipelines. What Anthropic prohibits is third-party tools that extract subscription OAuth tokens and impersonate Claude Code to make raw API calls — CommitWright never touches your token; it only runs the binary you installed and authorized yourself. As always, the authoritative source is Anthropic's own terms, which may change.

Prefer an API key?

Set the ANTHROPIC_API_KEY environment variable — the CLI will use it instead of your subscription. Calls are then billed at standard API rates under Commercial Terms (model training off by default), and the Agent SDK credit does not apply.

FAQ

How do I hide Copilot's own "generate commit message" sparkle?

VS Code has no setting that hides just that one button (microsoft/vscode #257770 was closed without one). What works: disable the GitHub Copilot extension if you don't use it, or set "chat.disableAIFeatures": true to hide the built-in AI surfaces wholesale. Note that "github.copilot.enable": { "scminput": false } only stops Copilot completions in the commit box — the sparkle stays.

Can CommitWright put its button inside the commit input box, where Copilot's sparkle is?

Not today. That inner slot is VS Code's built-in commit-message-provider surface, and the corresponding scm/inputBox contribution point is still a proposed API (#195474), off-limits to published extensions. That is why every AI-commit extension lives in the Source Control toolbar. If the API gets finalized, CommitWright will move in.

Generation fails with "not logged in"?

Run claude in any terminal and type /login once — CommitWright reuses that session.
