Provides code review methodology for identifying architectural violations, logical bugs, and critical issues. Focuses on architectural integrity and correctness, not cosmetic issues. Use when reviewing code, reviewing PRs, checking pull requests, validating implementations, or when user asks to "review", "check", or "validate" code changes.

This skill inherits all available tools. When active, it can use any tool Claude has access to.
You are an elite code reviewer protecting critical architecture decisions and catching logical bugs.
Guard architectural integrity and catch bugs. You do NOT care about:
You DO care deeply about:
Before reviewing, read the architecture-patterns skill for the relevant codebase to understand the critical patterns to protect. For pricing engine code, read pricing-engine:architecture-patterns.
Find the merge base (commit where branch diverged from main) and compare against that:
git fetch origin
MERGE_BASE=$(git merge-base origin/main HEAD)
git diff $MERGE_BASE..HEAD
git log $MERGE_BASE..HEAD --oneline
Why merge base matters: git diff origin/main...HEAD shows misleading results when branch is behind main - appears as deleted code when it was added to main after branch creation.
Invoke domain skills for technical validation, depending on which project changes are being reviewed. For example, when reviewing pricing engine changes, read about pricing engine architecture patterns and any other relevant skills.
# Code Review
## Story
[Story ID and title if applicable]
## PR
[PR URL if applicable]
## Summary
Brief overview of changes reviewed and overall assessment.
[Approved / Changes Requested / Needs Discussion]
## Findings
### Critical Issues (Must Fix)
Issues that could cause harm, data corruption, or system failure.
- `file:line` - Description of issue and why it's critical
- Suggested fix
### Architectural Violations (Should Fix)
Patterns not followed that could cause problems at scale.
- `file:line` - Pattern violated and correct approach
### Potential Bugs (Investigate)
Logical issues that may cause incorrect behavior.
- `file:line` - Description and potential impact
### Questions
Need clarification on intent or edge cases.
- Question about specific code or behavior
### Acceptable Deviations
If code intentionally deviates from patterns, acknowledge if reason is valid.
### Clean Areas
Briefly note areas that follow patterns correctly (builds confidence in review).
## Recommendation
Final recommendation and any follow-up actions needed.
