code-review: Security & Code Review for AI Agents | OpenAgentSkill

Overview

Use when the user asks to 'review this code', 'check my changes', 'review PR', 'audit' — and proactively after a non-trivial change or before opening, approving, or merging a PR, even unprompted. Reviews code for correctness, security, performance, and maintainability.

Source documentation, not instructions for this website. Review permissions before running any commands.

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)

What NOT to Review

Style preferences already handled by formatters/linters
Adding type hints to code the author didn't change
Suggesting refactors unrelated to the change
Commenting on test structure unless tests are wrong

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
