Summary
Teaches Claude how to profile CPU performance on Linux using perf, from quick hardware counter snapshots with perf stat to full sampling with perf record and flamegraph generation. Covers the permissions dance (perf_event_paranoid), fixing [unknown] symbols with frame pointers or DWARF unwinding, and interpreting metrics like IPC and cache miss rates. The workflow is comprehensive, walking through record, report, annotate, and integration with Brendan Gregg's flamegraph tools. Honestly one of the most complete perf references I've seen packaged as a skill. If you're doing performance work on Linux and keep forgetting which perf flags to use or how to read the TUI, this will save you a lot of time.
