Contribution Issue (worker skill)

Works the Drupal issue lifecycle so the contribution is meaningful, not duplicate.

Backs /drupal-ai-contrib:issue. Load the knowledge layer via dev-guides-navigator: drupal/contributing/drupal-issue-lifecycle, drupal/contributing/issue-forks-merge-requests, drupal/contributing/contribution-etiquette-rtbc-credit, drupal/contributing-with-ai/issue-creation.

Procedure

1. Review prior work FIRST — before anything else

For an existing issue, review what has already happened:

• Read existing comments, the issue status, and any open merge requests.
• Determine whether the contribution would duplicate work in progress.
• If someone is actively on it, surface that — coordinate, do not compete.
