code-review is a skill for Claude Code, Cursor from renanflustosa/octo-cluster. It costs 53 tokens per session (400 once invoked), scanned A, original, MIT.

A guide for reviewing a GitHub pull request, which is a proposed set of code changes awaiting review. It checks the changed files for bugs, security problems, performance issues, and code quality.

In plain words
What is it for?
Use it to review an existing pull request, either across all categories or specifically for bugs, security, or performance. It is not for local uncommitted changes or merging pull requests.
Why use it?
It gives reviews a consistent structure and keeps important findings from being missed. Findings are grouped by severity and tied to exact file and line locations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Review Pull Request

Mode: $ARGUMENTS

If mode is one of the following, adjust the review:

  • BUGS: Focus only on logical or other bugs
  • SECURITY: Focus only on security issues
  • PERFORMANCE: Focus only on performance issues

Pre-loaded context

  • PR details: !gh pr view
  • PR diff: !gh pr diff
  • Changed files: !gh pr diff --name-only

Workflow

  1. Analyze the diff and pre-loaded PR context
  2. Read changed files to understand full context
  3. Review based on mode (or all categories if no mode set)
  4. Provide structured feedback

Output format

Group by severity:

  • Critical - must fix before merge (bugs, security vulnerabilities)
  • Suggestions - improvements worth considering
  • Positives - good patterns to call out

Use file:line references for all findings. Include suggested fix for each critical issue.

See examples.md for output format and review-checklist.md for full checklist.

Rules

  • Review ALL changed files, not just the latest commit
  • Be specific: file:line + issue + suggested fix
  • Separate critical issues from suggestions

Error Handling

  • If gh pr view fails → run gh auth status to verify authentication; ask user for PR number if not on a PR branch
  • If a changed file is deleted in the PR → skip reading it; note it was removed
  • If diff is too large → prioritize changed files with highest risk (auth, payments, data mutation)
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
