Steps:

•Get PR info with mcp__acp__Bash: gh pr view $ARGUMENTS --json title,body,author,headRefName
•Checkout the PR branch locally with mcp__acp__Bash: git fetch origin {headRefName} && git checkout {headRefName}
•Save the complete diff to a temp file with mcp__acp__Bash: gh pr diff {PR_NUMBER} --repo {owner}/{repo} > /tmp/pr_diff.txt IMPORTANT: Use mcp__acp__Bash directly, NOT the Task tool or any agent.
•Read the diff file with mcp__acp__Read: /tmp/pr_diff.txt
•
Assess diff size:
- •Small (<300 lines): Direct review
- •Medium (300-800 lines): Group by directory, review systematically
- •Large (>800 lines): Enter plan mode, create review strategy, ask user which areas to focus on
•
First pass: Identify potential issues in the diff
- •Before commenting on any file, verify it exists locally with the path from the diff
- •If a file path doesn't exist, skip that comment and warn
•
Self-review: For each identified issue, verify it's actually valid:
- •Read the surrounding code context, not just the diff
- •Check if guards, comments, or other code already addresses the concern
- •Ask: Is this a real problem or just pedantic/stylistic?
- •Ask: Would this comment actually help the author?
- •Remove issues that are already handled by existing code
- •Remove issues that are just noise or obvious from context
•Present the filtered review to the user in the following format:
