ast-indexlisted
This skill should be used when the user asks to "find a class", "search for symbol", "find usages", "find implementations", "search codebase", "find file", "class hierarchy", "find callers", "module dependencies", "unused dependencies", "project map", "project conventions", "project structure", "what frameworks", "what architecture", "find Perl subs", "Perl exports", "find Python class", "Go struct", "Go interface", "find React component", "find TypeScript interface", "find Rust struct", "find Ruby class", "find C# controller", "find Dart class", "find Flutter widget", "find mixin", "find Scala trait", "find case class", "find object", "find PHP class", "find Laravel model", "find PHP trait", or needs fast code search in Android/Kotlin/Java, iOS/Swift/ObjC, Dart/Flutter, TypeScript/JavaScript, Rust, Ruby, C#, Scala, PHP, Perl, Python, Go, C++, or Protocol Buffers projects. Also triggered by mentions of "ast-index" CLI tool.

# ast-index - Code Search for Multi-Platform Projects
Fast native Rust CLI for structural code search in Android/Kotlin/Java, iOS/Swift/ObjC, Dart/Flutter, TypeScript/JavaScript, Rust, Ruby, C#, Scala, PHP, Perl, Python, Go, C++, and Proto projects using SQLite + FTS5 index.
## Critical Rules
**ALWAYS use ast-index FIRST for any code search task.** These rules are mandatory:
1. **ast-index is the PRIMARY search tool** — use it before grep, ripgrep, or Search tool
2. **DO NOT duplicate results** — if ast-index found usages/implementations, that IS the complete answer
3. **DO NOT run grep "for completeness"** after ast-index returns results
4. **Use grep/Search ONLY when:**
- ast-index returns empty results
- Searching for regex patterns (ast-index uses literal match)
- Searching for string literals inside code (`"some text"`)
- Searching in comments content
**Why:** ast-index is 17-69x faster than grep (1-10ms vs 200ms-3s) and returns structured, accurate results.
## Prerequisites
Install the CLI before use:
```bash
brew tap defendend/ast-index
brew install ast-index
```
Initialize index in project root:
```bash
cd /path/to/project
ast-index rebuild
```
The index is stored at `~/Library/Caches/ast-index/<project-hash>/index.db` (macOS) or `~/.cache/ast-index/<project-hash>/index.db` (Linux). Rebuild deletes the DB file entirely and creates a fresh index.
