Function Call Tracing

Quick Review

This skill provides clear instructions for instrumenting C/C++ programs with function call tracing and converting to Perfetto format. The description adequately explains the capability, and the task knowledge is comprehensive with build commands, usage steps, and build system integration examples. However, the skill references two critical source files (trace_instrument.c and trace_to_perfetto.cpp) that contain the actual implementation logic - while the SKILL.md provides good overview and integration steps, a CLI agent would need those files to execute the skill. The structure is reasonable but could benefit from separating the detailed build system examples into a separate file. Novelty is moderate: while the specific Perfetto integration is useful, the underlying -finstrument-functions approach is a standard GCC feature, and a capable CLI agent could research and implement this with sufficient tokens. The skill's main value is packaging the complete workflow (instrumentation + conversion + visualization) in a ready-to-use format, which provides convenience but not breakthrough capability reduction.
