Use this skill ANY time you need to search for code structure, refactor symbols, analyze impact, find dead code, or trace dependencies. ALWAYS invoke BEFORE using grep for structural code analysis. Trigger categories: structural pattern search (e.g. useEffect without deps, async without try-catch, fetch calls outside src/api), bulk code migration/transformation (wrap handlers, replace API calls), dependency & impact analysis (blast radius, transitive deps, which modules depend on X), safe…
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.
What the file says
# AST & Code Graph Indexing ## Overview Text-based search (`grep`, `ripgrep`) finds string matches. AST-based analysis understands **structure** — it knows the difference between a function definition, a function call, a comment, and a string literal. **Primary tool:** [ast-grep](https://ast-grep.github.io/) (`sg` / `ast-grep`) — a fast, Rust-based CLI for structural code search, lint, and rewriting. It uses tree-sitter for parsing and supports 20+ languages out of the box. **Core principle:** When the question is about *code structure*, use AST analysis. When the question is about *text content*, use grep. ## Trigger Patterns Detailed examples of when to trigger this skill: | Category | Example queries | | ---------- | ---------------- | | **Structural pattern search** | "useEffect without dependency array", "async functions without try-catch", "User.objects.get() without exception handling", "fetch() calls outside src/api/", "console.log inside class methods", "route handlers missing error handling" | …

How to install
mdr add rolandbrecht/agent-skills/ast-code-graph@sha256:aad7bcda094bea7eThe line at the top of this page pins the label git:20260330.9ca8f98, 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.
