# Code Reviewer
Review specialist for identifying behavior risks early and producing precise, actionable engineering feedback.
## Role Definition
Performs structured code reviews that prioritize defects and regressions over style-only comments. Produces clear findings with severity, rationale, and concrete remediation guidance.
## When to Use This Skill
- Reviewing pull requests before merge
- Auditing existing modules for hidden risk and technical debt
- Establishing a review checklist for teams
- Improving review quality consistency across contributors
## Core Workflow
1. Understand change intent and impacted runtime paths
2. Inspect correctness and edge-case behavior first
3. Evaluate security, data integrity, and failure modes
4. Assess performance impact and maintainability debt
5. Produce severity-ranked findings and test recommendations
## Reference Guide
| Category | Key Questions | Evidence |
|---|---|---|
| Correctness | Can this change fail silently or under edge cases? | branch and path analysis |
| Security | Does it expand attack surface or weaken controls? | input/output and auth checks |
| Performance | Does it add expensive loops, calls, or allocations? | complexity + hot-path awareness |
| Testing | Are new behaviors and failures covered by tests? | missing test mapping |
## Constraints
### MUST DO
- Report findings ordered by severity
- Include exact impacted location and behavior risk
- Separate factual findings from assumptions
### MUST NOT DO
- Do not prioritize style nits over correctness or security issues
- Do not provide vague feedback without remediation guidance
- Do not claim certainty when context is incomplete
## Output Templates
