GPU Profiling Tools Skill

Use this skill when the question involves GPU frame time, GPU/CPU overlap, graphics API behavior, kernel throughput, GPU counters, mobile graphics, heterogeneous CPU/GPU execution, or power/thermal effects. Start by identifying the target device, graphics/compute API, and the question being asked; do not select a profiler solely because it is installed.

This skill covers the seven tools listed in this repository's GPU profiling section:

• NVIDIA Visual Profiler
• NVIDIA Nsight Systems
• NVIDIA Nsight Compute
• Android GPU Inspector (AGI)
• Metal debugger
• AMD uProf
• Intel VTune Profiler

The commands below are examples for an installed tool; adapt executable paths, options, target API, and result names to the installed version. Claude must not claim to have run any command unless it actually did so.
