perf-profiler is a Claude Code skill that profiles CPU and memory hot paths, capturing hotspots and flame graphs with evidence.
About
perf-profiler runs profiling tools to capture CPU and memory hot paths with evidence. It verifies debug symbols first, captures file:line for each hotspot, and produces a flame graph or equivalent artifact where possible. A developer uses it to pinpoint exactly where time or memory is being spent during a performance scenario. It refuses to profile without a clear scenario and keeps outputs minimal and evidence-backed.
- Runs profiling tools to capture CPU/memory hotspots with evidence
- Generates flame graphs or equivalent output and captures file:line hotspots
- Verifies debug symbols before profiling

What it does
Profile CPU and memory hot paths and capture file:line hotspots with a flame graph.
Who is it for?
Pinpointing CPU/memory hotspots with file:line evidence and a flame graph.
Skip if: Profiling without a clear scenario, which it refuses.
When should I use this skill?
You are profiling CPU/memory hot paths, generating flame graphs, or capturing JFR/perf evidence.
What you get
- Hotspot file:line list plus a flame graph or profile artifact
