Can it identify memory leaks?

Yes, it audits resource management for issues like unclosed connections, event listeners that are never removed, and large objects held in closures.

How does the confidence scoring work?

Each finding is assigned a score from 0-100 based on the evidence; only findings with a score of 80 or above are reported to ensure high-quality, actionable feedback.

What does the Performance Review skill do?

It analyzes code to find bottlenecks like inefficient loops, database N+1 issues, and memory leaks using a structured, evidence-based approach that estimates real-world impact.

How does it handle database efficiency?

The skill identifies common I/O issues such as queries inside loops, missing pagination, and sequential calls that should be parallelized, providing before-and-after code examples for fixes.

What is the difference between a hot path and a cold path?

A hot path is code executed frequently where performance is critical for UX, while a cold path is rarely run (like migrations); the skill prioritizes optimizations for hot paths.

开发者工具

Analyzes codebases to identify performance bottlenecks, inefficient algorithms, and resource management issues using evidence-based metrics.

The Performance Review skill provides a rigorous, three-phase framework for evaluating how code behaves under production load and scale. It moves beyond vague observations to provide concrete, evidence-based findings on algorithmic complexity, N+1 query patterns, and memory management. By assessing project context, comparing against established patterns, and categorizing issues into specific performance buckets, it ensures that optimizations are targeted, high-confidence, and actionable for high-traffic environments.
