ast-grep skillA

ast-grep is agent-read markdown (skill) from sparq-org/sparq: Understand code STRUCTURE without reading whole files — outline a large file to its signatures, structural-grep every impl of a trait, and find call sites — using ast-grep (tree-sitter structural matching) and the editor outline/LSP, and knowing WHEN to reach for ast-grep vs Grep vs LSP vs a full Read. Use on the 37-crate / ~568-file Rust workspace when a question is about code SHAPE (impls / call patterns / signatures / codemods) rather than an exact string. MANDATORY: install + verify ast-grep.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/ast-grep@git:20260622.ac19bb8
Exact content
mdr add sparq-org/sparq/ast-grep@sha256:e0b6a26a7ffba591

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
