Commit Message Generator for Claude Code
A Visual Studio Code extension that writes your Git commit messages, and names new branches, with Claude Code.
Install: VS Code Marketplace, or search for Commit Message Generator for Claude Code in the VS Code Extensions view (Ctrl+Shift+X). A .vsix for manual install is on the Releases page.
It adds two buttons to the title bar of the Source Control view:
| Button |
What it does |
| ✨ Generate Commit Message |
Writes a commit message for your changes into the commit box. |
| ⎇ Generate New Branch from Changes |
Suggests a branch name for your changes, then creates the branch and switches to it. |
It runs through the Claude Code CLI you are already logged into, so there is no API key to set up.
Commit messages
Click ✨ and the message is written into the commit box.
- Streams in: the message appears as it is written, usually in about 3 seconds.
- Stop any time: while it is writing, the button becomes ⏹.
- Staged-aware: if you have staged changes, only those are described. Otherwise it describes all changes, including new files.
- Matches your style: your recent commit subjects are included, so the message follows your conventions. The format is Conventional Commits (
feat: …, fix: …).
- Your language: set
claudeCommitMsg.language to get messages in Turkish, German, and other languages.
Branch names
Started working on main and want a branch for it? Click ⎇, right next to ✨.
- Claude suggests a short name such as
feat/add-login-page in about 3 seconds, following the style of your existing branches.
- The name opens in an input box, where you can edit it. Invalid names and names that already exist are flagged.
- Press Enter: the branch is created and checked out. Your uncommitted changes come along.
Also available under ⋯ → Branch → Generate New Branch from Changes (Claude) and in the Command Palette. Branch names are always lowercase English, whatever the message language is.
Good to know
- Works on Windows, macOS, Linux, WSL and Remote SSH.
- If Claude Code is not logged in, you get a Log In button that opens a terminal to log in. If the CLI is not installed, you get a link to install it.
Requirements
- Claude Code installed and logged in (
claude must work in a terminal). Usage counts against the account the CLI is logged in with.
- Visual Studio Code 1.90 or newer.
- Git.
