add-uint-support provides step-by-step guidance for expanding pytorch operator type coverage to unsigned integers via AT_DISPATCH macro updates, with clear decision paths between two implementation methods.

at-dispatch-v2 converts legacy pytorch AT_DISPATCH macros to the v2 api with step-by-step mapping of type groups, lambda wrapping, and argument reordering for aten kernels and cuda implementations.

metal-kernel covers implementing native Metal kernels for PyTorch operators on Apple Silicon via c10/metal infrastructure rather than MPSGraph, with workflows for new operators and MPSGraph migration.

skill covers pytorch docstring conventions using sphinx/rest format with sections for signature, description, arguments and examples, though the actual file content appears truncated or incomplete.
