PR Review Skill

Review a Pull Request comprehensively by analyzing the diff against the upstream merge base.

Prerequisites Check (MUST verify first)

Before proceeding, verify:

# 1. Check if in a git repository
git rev-parse --is-inside-work-tree

# 2. Check if gh CLI is available and authenticated
gh auth status

If either check fails, STOP and inform the user:

• Not in git repo → "This skill requires a git repository. Please navigate to a git project."
