Spark Commit

AI-powered git commit message generator for VS Code. Click the ✨ button in the Source Control panel and let Claude Code draft your commit message from the staged diff.

Spark Commit adds no proxy, no telemetry, and no third-party collection of its own. Your staged diff flows from VS Code to the Claude CLI on your machine, which then sends it to Anthropic under your own account — the same data path claude uses when you run it in a terminal.

Requirements

Claude Code CLI installed and authenticated. Verify with claude --version.
Git (comes with VS Code's git extension; the CLI must be on PATH).
VS Code ^1.85.0.

Install

From the VS Code Marketplace: search for Spark Commit and install.

Or build from source:

npm install
npm run compile
npm run package
code --install-extension spark-commit-*.vsix

Usage

Stage changes with git add (or via the Source Control panel).
Open the Source Control panel.
Click the ✨ icon in the panel's title bar.
The commit message field animates with ⏳ Generating commit message….
Claude reads the staged diff, generates a message, and writes it to the field.
Review, edit if needed, commit.

The button also works via the Command Palette: Spark Commit: Generate Commit Message.

In a multi-repository workspace the button operates on the repo whose title you clicked. When invoked from the Command Palette, the extension picks the repo of the active editor — or asks you if none matches.

Settings

Open Preferences → Extensions → Spark Commit.

Setting	Description
`sparkCommit.cliPath`	Absolute path to the Claude CLI. Leave empty to use `claude` from PATH. Useful when VS Code doesn't inherit PATH from your shell.
`sparkCommit.prompt`	Prompt template passed to Claude. Use `{diff}` as a placeholder for the staged diff. If `{diff}` is missing, the diff is appended at the end.
`sparkCommit.model`	Model passed to the Claude CLI via `--model`. Shortcuts: `sonnet`, `opus`, `haiku`. Exact versions like `claude-opus-4-7` also work. Empty = CLI default.

Why Spark Commit

The VS Code Source Control panel has a built-in ✨ button, but it only works with GitHub Copilot and can't be rebound to another provider. Community alternatives exist but are small projects without audit. Spark Commit is minimal (≈150 lines of TypeScript, no runtime dependencies) — you can read the whole source before trusting it.
