driangle Input
Accepts a PR URL (e.g. https://github.com/org/repo/pull/123) or a PR number (for the current repo).
Steps
Fetch in parallel:
gh pr view <pr> --json title,body,files,additions,deletions,baseRefName,headRefNamegh pr diff <pr>- Check if the repo has a CLAUDE.md (factor its conventions into the review)
- Only if the user explicitly asks:
gh api repos/{owner}/{repo}/pulls/{number}/comments
Read the full diff carefully. For large diffs, read persisted output files fully.
Write a clear explanation of the PR:
- What problem does this PR solve and why?
- What approach was taken — summarize the key changes across files
- Call out any notable design decisions or trade-offs
Review for: bugs, missing error handling, security issues, performance problems, naming/readability, convention violations, lock file anomalies, unsafe casts/patterns.
Categorize each finding: High, Medium, Low, or Nit.
Output
Print the review directly — do NOT post comments to the PR unless the user explicitly asks.
Format: H2 title with PR name, then a "What this PR does" section explaining the changes (from step 3), followed by issues listed with severity, file:line reference, and concrete suggestion. End with a "Positives" section noting what was done well.
