Acting as a central orchestration hub for PyTorch development, this skill systematically matches technical symptoms like CUDA out-of-memory errors, NaN losses, or low GPU utilization to targeted specialist modules. It enforces a diagnosis-first methodology that prioritizes profiling and systematic debugging over trial-and-error, ensuring developers receive precise guidance for complex tasks ranging from custom autograd implementation and mixed-precision optimization to distributed training setup and reproducible checkpointing.
