What's Wrong?

The Claude GitHub App stopped applying claude-code-assisted labels to merged PRs around Feb 25, 2026. We have contribution metrics enabled via Claude for Teams with GitHub analytics connected.

Timeline

• Feb 25 — Last claude-code-assisted label applied (to a merged PR)
• Feb 27 — integration_installation.version_updated audit log event for the Claude app on our org
• Feb 27 → present — Zero labels applied despite dozens of merged PRs containing Co-Authored-By: Claude trailers and active Claude Code sessions

What Should Happen?

Per docs: "Merged pull requests containing Claude Code-assisted lines are labeled as claude-code-assisted in GitHub."
