Test it
Using "performance-profiler". A controller loads users and then fetches posts inside a loop.
Expected outcome:
- Flags the N+1 pattern as high priority.
- Recommends eager loading or a single joined query.
- Explains the request impact as the user count grows.
Using "performance-profiler". A React list rerenders when filters change.
Expected outcome:
- Identifies avoidable rerender triggers.
- Suggests memoization only where it reduces measured work.
- Recommends virtual scrolling for long result sets.
Using "performance-profiler". A team wants a performance review before launch.
Expected outcome:
- Groups findings by critical, high, and medium priority.
- Connects each issue to expected user impact.
- Adds profiling tools that can verify the assumptions.
Security Audit
SafeNo evidence of malicious behavior, prompt injection, command execution, network exfiltration, or hidden runtime code was found in the reviewed files. The static findings are markdown examples or performance guidance for code review workflows.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Review Database Query Performance
Find query patterns that increase latency, including N+1 queries, missing indexes, wide selects, and missing pagination.
Reduce UI Rendering Cost
Check frontend components for unnecessary rerenders, bundle size issues, missing lazy loading, and expensive UI operations.
Prepare Performance Review Notes
Create a prioritized report that explains impact, suggested fixes, and profiling tools for release readiness reviews.
Try These Prompts
Review this code for clear performance issues. Focus on queries, loops, memory leaks, and frontend rendering problems.
Analyze the attached feature for performance bottlenecks. Rank issues by user impact, implementation effort, and confidence.
Review these proposed optimizations. Explain trade-offs, expected gains, and risks for maintainability.
Build a profiling plan for this service. Include hypotheses, metrics, tools, expected evidence, and follow-up fixes.
Best Practices
- Profile before changing code so fixes target measured bottlenecks.
- Prioritize hot paths and high-traffic workflows before rare cases.
- Measure before and after each change to confirm real improvement.
Avoid
- Optimizing code without a measured problem.
- Adding caching without invalidation, limits, or ownership.
- Trading clear code for minor performance gains without evidence.
