Skill: GitHub PR & Git Management

Goal

Standardize how the Gemini CLI Bot stages its changes, generates Pull Request descriptions, and manages the lifecycle of both new and existing PRs.

Staging & Patch Preparation (MANDATORY)

If you are proposing fixes and PR creation is enabled (per the System Directive):

1. Surgical Changes: Only propose a single improvement or fix per PR.
   • No Bundling: You are STRICTLY FORBIDDEN from bundling unrelated changes. Changes are unrelated if they address different root causes.
   • Examples: Do not combine a script fix with a documentation update, an unrelated refactor, or a metrics script update. Metrics and fixes MUST be in separate PRs.
2. Generate PR Description: Use the write_file tool to create pr-description.md.
   • Title: The very first line MUST be a concise, conventional title.
   • Body: The rest should be the markdown body explaining the change, why it is recommended, and the expected impact.
3. Stage Fixes: You MUST explicitly stage your fixes using the git add <files> command.
4. Internal File Protection (CRITICAL): You are STRICTLY FORBIDDEN from staging internal bot management files. If they are accidentally staged, you MUST unstage them using git reset <file>.
   • NEVER STAGE: pr-description.md, lessons-learned.md, branch-name.txt, pr-comment.md, pr-number.txt, issue-comment.md, or anything in history/.

Unblocking & PR Updates (Recovery)

If you are continuing work on an existing Task or responding to a comment on an existing bot PR:

1. Target Existing Branch: Use write_file to generate branch-name.txt containing the current branch name (e.g., bot/task-BT-01).
2. Track PR ID: Use write_file to generate pr-number.txt containing the numeric PR ID.
3. Respond to Maintainers:
   • For general responses, write your markdown comment to issue-comment.md.
   • For specific PR feedback, write your markdown response to pr-comment.md.
4. Handle CI Failures: Diagnose failing checks using gh run view. Your priority must be generating a new patch and staging it with git add to fix the failure.
