Official Provider SkillView repo

Use when Pyrefly computes a wrong tensor shape (or is missing one that can't be expressed in a stub signature) and you need to add or fix a shape-DSL rule. Requires a Pyrefly checkout (fbsource or a clone); not usable from a pip/site-packages install.

Add Shape Types To Torch ModelPort a PyTorch model to use pyrefly's tensor shape type system (Tensor[[B, C, H, W]], Int[T]). Use this skill whenever the user wants to add shape annotations to a PyTorch model, type a model with tensor dimensions, port a model to use shape tracking, or annotate model forward methods with tensor shapes. Also use when the user mentions tensor shape ports, Int types for PyTorch, or pyrefly shape checking on a model file. Invoke BEFORE starting any model port — the skill's gated workflow prevents Add Torch Shapes ExampleUse when adding a new PyTorch model to Pyrefly's shape-tracking example corpus under tensor-shapes/pyrefly-torch-stubs/examples — i.e. importing a model as a tested, corpus-quality reference port. This is maintainer-facing fbsource work. For porting your own model elsewhere, use the porting skill directly; for fixing a wrong/missing shape rule, use modify-shaped-array-dsl.Benchmark PyreflyRun Pyrefly benchmarks locally via Buck or Cargo, including PyTorch real-world LSP benchmarks. Use when user asks to benchmark pyrefly performance, run pyrefly bench, compare cold start vs error propagation, or update PyTorch benchmark pin.Review Pyrefly DiffReviews a comma separated pyrefly diff according to the pyrefly review best practices.Score Pyrefly ChangeProduces a scorecard evaluating a pyrefly change on correctness and quality.Relay E2e TestWrite and run markdown-driven e2e tests for Relay. Covers fixture format, server/client code patterns, interaction DSL, snapshots, and running tests.
