When to Use This Skill

ALWAYS use when:

• User wants to work with merge requests
• User mentions "MR", "merge request", "pull request", or related terms

NEVER use when:

• User wants bulk operations on 10+ MRs (use gitlab-bulk instead)
• User is only searching/filtering MRs (use gitlab-search instead)
