Claude Code automatically appends session URLs to commit messages and PR descriptions

Unwanted URL Appended to Git History

Claude Code, an AI coding assistant, automatically appends a session URL (e.g., "https://claude.ai/code/session_...") to every commit message and pull request description it generates. This occurs by default, without any explicit opt-in prompt or warning to the user during onboarding or usage.

Developer Concerns and Impact

Developers using Claude Code have expressed concerns that these automatically added URLs make their git history appear unprofessional and cluttered. The lack of transparency regarding this feature means users only discover it after it has already been integrated into their version control system.

Proposed Solutions for User Control

The primary proposed solution is to make the inclusion of the session URL an opt-in feature. This could involve a one-time prompt during onboarding asking if the user wishes to include a link back to the Claude session in commit messages. Alternative suggestions include making an opt-out setting more discoverable, possibly with a "Don't add this again" option during the first commit, or removing the URL entirely and relying on the existing "Co-Authored-By: Claude" trailer for attribution.

Existing but Undiscovered Settings

While a setting exists to suppress this behavior (attribution.commit: "" in .claude/settings.json), it is not easily discoverable by users. Additionally, using a commit-msg git hook can strip the URL, but this method is not always reliable in remote or cloud development environments.
