Initialize ast-index for Android Project

This command sets up ast-index integration for an Android/Kotlin/Java project.

Steps to Execute

1. Check Prerequisites

Verify ast-index is installed:

ast-index version

If not installed, inform user to run:

brew tap defendend/ast-index
brew install ast-index

2. Create/Update .claude/settings.json

First, ensure the directory exists:

mkdir -p .claude

Then create or merge into .claude/settings.json. If file doesn't exist, create it with this content:

{
  "extraKnownMarketplaces": {
    "ast-index": {
      "source": {
        "source": "github",
        "repo": "defendend/Claude-ast-index-search"
      }
    }
  },
  "enabledPlugins": {
    "ast-index@ast-index": true
  },
  "permissions": {
    "allow": [
      "Bash(ya tool ast-index *)",
      "Bash(ast-index *)"
    ]
  }
}

Important: If .claude/settings.json already exists, MERGE the keys (don't replace the whole file).

3. Create .claude/rules/ast-index.md (CRITICAL)

Create the rules directory and ast-index rules file:

mkdir -p .claude/rules

Create file .claude/rules/ast-index.md with this content:

# ast-index Rules

## Mandatory Search Rules

1. **ALWAYS use ast-index FIRST** for any code search task
2. **NEVER 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

ast-index is 17-69x faster than grep (1-10ms vs 200ms-3s) and returns structured, accurate results.
