The Agent Skills Directory

[SAFE]: The skill implements a profiling tool using sys.setprofile and threading.setprofile to trace Python function calls. This is a standard approach for diagnostic and performance instrumentation.
[EXTERNAL_DOWNLOADS]: The skill requires the nvtx Python package, which is an official NVIDIA library for performance markers. This dependency is appropriate for the skill's stated purpose of NVTX profiling.
[COMMAND_EXECUTION]: The skill provides examples of running nsys (NVIDIA Nsight Systems) and uv run python. These are legitimate development commands for profiling and running Python applications in the intended NVIDIA-based environment.
[SAFE]: The use of sitecustomize.py via PYTHONPATH is a well-documented Python feature for extending interpreter startup behavior. In this context, it is used transparently to initialize the profiling hook without permanently modifying the environment's configuration files.
