code-review

code-review is a skill for Claude Code from arozumenko/sdlc-skills. It costs 64 tokens per session (629 once invoked), scanned A, original, MIT.

A structured review of code changes for correctness, security, performance, and maintainability. It can examine working-tree changes, staged changes, pull requests, or selected files.

In plain words
What is it for?
Use it to review a pull request, inspect local changes, audit specific files, and check edge cases, error handling, secrets, authorization, and database access patterns.
Why use it?
It helps find bugs, unsafe input handling, permission problems, concurrency errors, slow code, and other risks before changes are merged. The review focuses on impact rather than formatting preferences.

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 7d 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.

Code Review

Systematic code review focused on what matters. Not a style police — a correctness and risk checker.

Review Scope

Determine what to review:

# Review staged changes
git --no-pager diff --cached

# Review working tree changes
git --no-pager diff

# Review a PR
gh pr diff <number>

# Review specific files
# Just read them directly

Review Checklist

Check in this priority order. Stop at each category — don't rush to the next.

1. Correctness

  • Does it do what it claims?
  • Are edge cases handled (nulls, empty collections, boundary values)?
  • Are error paths correct (not swallowed, not over-caught)?
  • Do conditional branches cover all cases?

2. Security

  • Input validation at system boundaries (user input, API responses)?
  • SQL injection, XSS, command injection risks?
  • Secrets in code or logs?
  • Permissions and authorization checked?

3. Concurrency & State

  • Race conditions in shared state?
  • Proper locking/synchronization?
  • Async operations awaited correctly?
  • Resources properly closed/released?

4. Performance

  • O(n^2) or worse in hot paths?
  • Unnecessary allocations in loops?
  • N+1 query patterns?
  • Missing indexes for new queries?

5. Maintainability

  • Is the intent clear from reading the code?
  • Could someone unfamiliar modify this safely?
  • Are there implicit assumptions that should be explicit?

Output Format

Structure your review as:

## Summary
One sentence: what this change does and whether it looks good.

## Issues
### [Critical/Important/Nit] Title
File: path/to/file.py:42
Description of the issue and why it matters.
Suggested fix (if non-obvious).

## Questions
Things that aren't wrong but need clarification from the author.

Severity levels:

  • Critical — will break in production, security vulnerability, data loss risk
  • Important — correctness issue, significant performance problem, missing error handling
  • Nit — style, naming, minor improvement (limit to 2-3 max, don't pile on)

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.
