ClaudeCommit

AI-generated commit messages and TFVC check-in comments — directly inside Visual Studio.

One click in the Git Changes or Pending Changes panel sends your diff to Claude and injects the result straight into the message field. No copy-paste, no context switching, no API key to manage.

Features

• Git & TFVC support — works with both Git repositories and Team Foundation Version Control pending changes
• One-click generation — toolbar button in the Git Changes / Pending Changes panel triggers generation instantly
• Conventional Commits by default — default prompt produces type(scope): description messages
• Fully customizable prompts — edit the prompt template in Tools > Options > Claude Commit using {diff} and {status} placeholders
• Cancel mid-generation — a Cancel button replaces the toolbar button while Claude is running; click it to kill the process and restore the panel
• Error InfoBar — if the CLI is missing or fails, a non-blocking notification bar appears with context
• No API key required — the extension shells out to the claude CLI; authentication is handled by the CLI itself

Requirements

Claude CLI is a hard dependency. The extension does not call the Anthropic API directly — it spawns the claude process and captures its output. This keeps the extension thin and auth-free.

Installation

From Visual Studio Marketplace (coming soon)

Search for ClaudeCommit in Extensions > Manage Extensions or visit the Marketplace page.

From VSIX

1. Download the latest .vsix from the Releases page
2. Double-click the file — the VSIX installer opens automatically
3. Restart Visual Studio

Usage

1. Make changes in your repository
2. Open the Tools menu
3. Click the Generate Commit Message with Claude menu option
4. Claude generates a message and injects it into the commit message field
5. Review, edit if needed, then commit

For TFVC, the same process is available.

Configuration

Go to Tools > Options > Claude Commit.

Git Prompt Template

Template sent to Claude for Git commits. Default:

Generate a concise git commit message following the Conventional Commits format
(type(scope): description).

Changed files:
{status}

Diff:
{diff}

Output ONLY the commit message. No explanation, no markdown, no quotes.

TFVC Prompt Template

Same structure, used for TFVC check-in comments instead.

Placeholders

Claude CLI Path

Leave empty to use claude from your system PATH. Set an absolute path if you have a non-standard installation.

Architecture

The extension shells out to the claude CLI rather than calling the Anthropic API directly. This means:

• No API key stored in VS settings
• Authentication is managed by the CLI (same session the developer already uses)
• Model selection, rate limiting, and API versioning are handled by the CLI
• The extension stays thin with no Anthropic SDK dependency

Trade-off: the claude CLI must be installed. If it is missing, the InfoBar will surface an error explaining how to install it.

See ADR-0001 for the full decision record.

Building from source

git clone https://github.com/Isipharm/ClaudeCommit.git
cd ClaudeCommit
