pytorch-skill-writer guides users through creating well-structured agent skills for claude code, covering frontmatter validation, directory layout, discovery optimization via specific descriptions, and testing workflows.

pytorch-building covers compiling executorch from source across platforms, including python package installation, c++ runtime builds, model runners, cross-compilation for ios/android, and backend-specific configurations. routes users to the appropriate build path based on their target.

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 guides conversion of pytorch's legacy AT_DISPATCH macros to the v2 format, providing step-by-step transformation rules, type group mappings, and pattern examples for aten kernel porting.

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.

add-uint-support expands pytorch operator type coverage by injecting unsigned integer macros into AT_DISPATCH_V2 calls, offering two methods (explicit addition or integral type substitution) with decision trees and pattern examples.

pytorch-docstring covers docstring structure, sphinx formatting, and conventions for pytorch functions and methods, with detailed sections on args, returns, examples, and cross-references.

pytorch-triaging-issues routes github issues to oncall teams, applies module and type labels from an allowlist, closes questions with forum redirects, and flags high-priority items for human review. pt2 issues receive special handling requiring module labels before marking triaged.

pyrefly-type-coverage incrementally removes type-checking suppressions from python files by identifying and deleting file-level ignore directives, then running lintrunner to validate coverage gains.

pytorch-pr-review evaluates pytorch pull requests for code quality, test coverage, security, and backward compatibility issues that automated checks miss. the skill is philosophically sound but lacks procedural specificity and does not address failure modes or recovery paths.

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.

pytorch-setup activates a conda environment and runs an install script for executorch development, with optional huggingface integration via pinned commit.

Export a PyTorch model to .pte format for ExecuTorch. Use when converting models, lowering to edge, or generating .pte files.

Profile ExecuTorch model execution. Use when measuring performance, analyzing operator timing, or debugging slow models.

Write Metal/MPS kernels for PyTorch operators. Use when adding MPS device support to operators, implementing Metal shaders, or porting CUDA kernels to Apple Silicon. Covers native_functions.yaml dispatch, host-side operators, and Metal kernel implementation.

Debug AOTInductor (AOTI) errors and crashes. Use when encountering AOTI segfaults, device mismatch errors, constant loading failures, or runtime errors from aot_compile, aot_load, aoti_compile_and_package, or aoti_load_package.

Migrate a file to use stricter Pyrefly type checking with annotations required for all functions, classes, and attributes.
