Perf Profiler

composiohq/awesome-claude-pluginsOfficial

When you need to find out why your service is pegging CPU or leaking memory, this skill runs perf, JFR, or similar profilers and generates flame graphs as evidence. It enforces a contract: verify debug symbols first, capture file and line numbers for every hotspot, and output artifacts you can actually inspect. The skill won't let you profile without a clear scenario, which is good discipline. It's built around a minimal output format that lists the tool, command, hotspots with reasons, and paths to the flame graph or profile data. If you're doing performance work and want Claude to drive the profiler instead of fumbling through man pages, this gives you a structured way to do it.
