Commit Messages for Claude Code (VS Code)

Adds a button to the Source Control view that sends your changes to the Claude Code CLI (claude -p, uses your Claude subscription, no API key) and fills in a Conventional Commits message. VS Code port of the JetBrains plugin of the same name.

Requirements

• Claude Code installed and logged in: run claude once in a terminal.
• The built-in Git extension enabled.

Usage

Click the Claude icon in the Source Control title bar (or run Generate Commit Message with Claude from the Command Palette). The message streams into the commit box; a notification shows the detected type and offers Retry for a different wording. While it runs, the icon turns into a spinner that stops the request.

What is sent: the staged changes, or every change (including untracked files) when nothing is staged, the same set VS Code commits. Generated folders, lock files and minified bundles are listed by name only. The current branch and, optionally, the titles of the last 20 commits are sent too, so Claude can match the repository's style.

Screenshots

Result — the detected type and the reason, with Retry for a different wording:

Settings — model, language, fast mode, scope and more:

Settings

Under Settings → Extensions → Commit Messages for Claude Code: model and effort, message language (defaults to VS Code's), fast mode, timeout, match recent commit style, always include a scope, additional instructions, replace without asking and the path to the claude executable.

Privacy

The extension sends nothing by itself and has no telemetry: the local claude CLI sends the data above to Anthropic under your own account. See the privacy policy.

Development

npm install
npm test            # compiles and runs the unit tests (node:test)
npm run package     # → commit-messages-for-claude-code-<version>.vsix

Press F5 in VS Code to open an Extension Development Host with the extension loaded. Install the .vsix with Extensions → ⋯ → Install from VSIX….

src/client.ts, src/parser.ts, src/streamJson.ts and src/diff.ts have no VS Code dependencies and mirror the Kotlin plugin; the normal-mode prompt test uses the same expected text as ClaudeClientLegacyGoldenTest, so keep both in sync when the prompt changes.
