Use ast-grep (sg) to search, lint, and rewrite code across large codebases using AST pattern matching. A blazing-fast alternative to regex-based code transformations that understands syntax structure.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# ast-grep Structural Code Search and Rewrite Use ast-grep (sg) to search, lint, and rewrite code across large codebases using AST pattern matching. A blazing-fast alternative to regex-based code transformations that understands syntax structure. ## Installation Use the upstream install or setup path that matches your environment: - npm install --global @ast-grep/cli - pip install ast-grep-cli - brew install ast-grep - cargo install ast-grep --locked Requirements and caveats from upstream: - You can use $ sign + upper case letters as a [wildcard](https://en.wikipedia.org/wiki/Wildcard_character), e.g. $MATCH, to match any single AST node. Think of it as [regular expression dot](https://regexone.com/lesson... - You can install it from [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm), [pip](https://pypi.org/), [cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html), [cargo-binstall](...

How to install
mdr add agentskillexchange/skills/ast-grep Structural Code Search and Rewrite@sha256:359ff702e17d7d2fThe line at the top of this page pins the label git:20260710.62afd0f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
