Repository-local WinuxCmd workflow for AI agents: download a released WinuxCmd build, integrate it into .winuxcmd/bin, activate the workspace without touching global PATH, use man.exe on Windows, run MSVC builds/tests, and package the skill for release. Use when working in this repository or preparing WinuxCmd release assets and the skill bundle.

Linux perf performance analysis expert covering the complete workflow from environment setup through data collection, analysis, and bottleneck diagnosis. Expert in CPU profiling, call graph analysis, syscall tracing, and performance optimization. Use this skill whenever profiling C/C++/Rust/Go applications, diagnosing CPU bottlenecks, analyzing syscall overhead, or optimizing hot paths. IMPORTANT: Check permissions first. User-space profiling works without sudo, but kernel symbols require sudo to modify kptr_restrict and perf_event_paranoid. Focus on user-space optimization rather than kernel.
