What it does

Identify algorithmic and I/O perf defects

Best for

Catching O(n²) loops, N+1 queries, and async-blocking patterns that pass tests but fail in production

Inputs
  • · code diff or file path
  • · profiler artifacts (optional)
Outputs
  • · .claude/audits/performance.md with findings, severity, hot-path callsites
Requires
  • · Read
  • · Edit
  • · Write
  • · Bash
  • · Grep
  • · Glob
  • · WebFetch
Preconditions

Perf rules reference exists at ~/.claude/rules/performance.md

Failure modes
  • · Micro-optimizations flagged (JIT-handled)
  • · Performance finding without hot-path anchor
Trust signals
  • · Recommends measurement (profilers, EXPLAIN ANALYZE) over reasoning
  • · Distinguishes from code-simplifier and bug-hunter
