Every commit message and PR description created by Claude Code automatically includes a session URL at the bottom (e.g.https://claude.ai/code/session_…). There is no opt-in prompt, no warning, and no mention of it during onboarding. Users only discover it after it’s already polluting their git history.
Make the session URL attribution opt-in — don’t include it unless the user explicitly enables it. A one-time prompt during onboarding (“Would you like to include a link back to this Claude session in commit messages?”) would be the ideal UX.
A developer uses Claude Code to build a feature, commits the work, and opens a PR.Their teammates and open source contributors seehttps://claude.ai/code/session_… at the bottom of every commit and PR description.It looks unprofessional, clutters history, and the developer had no idea it was being added.
