notify-blame

To notify Git blame authors on Slack, use the /notify-blame command. It identifies code authors from Git diffs, maps them to Slack users, and sends direct messages containing the MR link and a summary of their specific code changes.

Yes, you can automatically detect the GitLab merge request URL. The tool resolves the MR URL directly from your current local branch context, or alternatively uses the GitLab CLI, explicit arguments, or prior chat history for precise targeting.

Yes, you need Python 3 to run the bundled git-blame-authors.py script. The script requires Python 3, the git CLI, and configured Slack integration access to successfully map Git authors to Slack users and deliver messages.

The best way to hold developers accountable for code changes during a review is DMing blame authors with MR context. It builds per-author summaries from diffs and sends personalized Slack messages, providing clear context and accelerating the review process.

Mapping Git blame authors to Slack users works by analyzing branch diffs to identify contributors, then using a person-to-user-map workflow. It builds per-author summaries from the code changes and delivers them as direct Slack messages with the MR link.

A limitation of auto-resolving a merge request URL from local context is potential detection failure if the branch lacks clear GitLab tracking. You can override automatic detection by explicitly providing an MR URL as an argument to ensure accurate Slack notifications.
