Review code changes for security, performance, and correctness. Trigger with a PR URL or diff, "review this before I merge", "is this code safe?", or when checking a change for N+1 queries, injection risks, missing edge cases, or error handling gaps.

Output

## Code Review: [PR title or file]
 
### Summary
[1-2 sentence overview of the changes and overall quality]
 
### Critical Issues
| # | File | Line | Issue | Severity |
|---|------|------|-------|----------|
| 1 | [file] | [line] | [description] | 🔴 Critical |
 
### Suggestions
| # | File | Line | Suggestion | Category |
|---|------|------|------------|----------|
| 1 | [file] | [line] | [description] | Performance |
 
### What Looks Good
- [Positive observations]
 
### Verdict
[Approve / Request Changes / Needs Discussion]

If Connectors Available

If ~~source control is connected:

Pull the PR diff automatically from the URL
Check CI status and test results

If ~~project tracker is connected:

Link findings to related tickets
Verify the PR addresses the stated requirements

If ~~knowledge base is connected:

Check changes against team coding standards and style guides

Tips

Provide context — "This is a hot path" or "This handles PII" helps me focus.
Specify concerns — "Focus on security" narrows the review.
Include tests — I'll check test coverage and quality too.~~
