ai-codeindex 0.20.0

AI-native code indexing tool for large codebases

codeindex

Universal Code Parser — Best-in-class multi-language AST parser for AI-assisted development.

codeindex extracts symbols, inheritance relationships, call graphs, and imports from Python, PHP, Java, TypeScript, and JavaScript using tree-sitter. Perfect for feeding structured code data to AI tools, knowledge graphs, and code intelligence platforms.

Features

• Multi-language AST parsing — Python, PHP, Java, TypeScript, JavaScript via tree-sitter (Go, Rust, C# planned)
• AI-powered documentation — Generate README files using Claude, GPT, or any AI CLI
• Single file parse — codeindex parse <file> with JSON output for tool integration
• Structured JSON output — --output json for CI/CD, knowledge graphs, and downstream tools
• Call relationship extraction — Function/method call graphs across Python, Java, PHP, TypeScript, JavaScript
• Inheritance extraction — Class hierarchy and interface relationships
• Framework route extraction — ThinkPHP and Spring Boot route tables (more planned)
• Technical debt analysis — Detect large files, god classes, symbol overload
• Smart indexing — Tiered documentation (overview → navigation → detailed) optimized for AI agents
• Adaptive symbol extraction — Dynamic 5–150 symbols per file based on size
• CLAUDE.md injection — codeindex init auto-configures Claude Code integration (v0.17.0)
• Template-based test generation — YAML + Jinja2 for rapid language support (88–91% time savings)
• Parallel scanning — Concurrent directory processing with configurable workers

---

Installation

codeindex uses lazy loading — language parsers are only imported when needed.

Quick Install

# All languages (recommended)
pip install ai-codeindex[all]

# Or specific languages only
pip install ai-codeindex[python]
pip install ai-codeindex[php]
pip install ai-codeindex[java]
pip install ai-codeindex[typescript]
pip install ai-codeindex[python,php]

Using pipx (Recommended for CLI use)

pipx install ai-codeindex[all]

From Source

git clone https://github.com/dreamlx/codeindex.git
cd codeindex
pip install -e ".[all]"

---

Quick Start

1. Initialize Your Project

cd /your/project
codeindex init

This creates:

• .codeindex.yaml — scan configuration (languages, include/exclude patterns)
• CLAUDE.md — injects codeindex instructions so Claude Code uses README_AI.md automatically
• CODEINDEX.md — project-level documentation reference

2. Scan Your Codebase

# Scan all directories (structural documentation, no AI needed)
codeindex scan-all

# Scan a single directory
codeindex scan ./src/auth

# AI-enhanced documentation (requires ai_command in config)
codeindex scan-all --ai

# Preview AI prompt without executing
codeindex scan ./src/auth --ai --dry-run

3. Check Status

codeindex status

Indexing Status
───────────────────────────────
✅ src/auth/
✅ src/utils/
⚠️  src/api/ (no README_AI.md)
Indexed: 2/3 (67%)

4. Generate Indexes

# Global symbol index (PROJECT_SYMBOLS.md)
codeindex symbols

# Module overview (PROJECT_INDEX.md)
codeindex index

# Git change impact analysis
codeindex affected --since HEAD~5

Claude Code Integration

v0.17.0: codeindex init automatically injects instructions into your project's CLAUDE.md, so Claude Code reads README_AI.md files first — no manual setup required.

# One command sets everything up
codeindex init

# Claude Code will now:
# ✅ Read README_AI.md before searching source files
# ✅ Use structured indexes for architecture understanding
# ✅ Navigate code via Serena MCP tools (find_symbol, etc.)

For manual setup, MCP skills (/mo:arch, /mo:index), and Git hooks integration, see the Claude Code Integration Guide.

Want to add a language? The template-based test system lets you contribute by writing YAML specs — no Python knowledge required. See CONTRIBUTING.md for details.

Framework Route Extraction

Framework	Language	Status
ThinkPHP	PHP	✅ Stable (v0.5.0)
Spring Boot	Java	✅ Stable (v0.8.0)
Laravel	PHP	📋 Planned
FastAPI	Python	📋 Planned
Django	Python	📋 Planned
Express.js	JS/TS	📋 Planned

How It Works

Directory → Scanner → Parser (tree-sitter) → Smart Writer → README_AI.md

1. Scanner — walks directories, filters by config patterns
2. Parser — extracts symbols (classes, functions, imports, calls, inheritance) via tree-sitter
3. Smart Writer — generates tiered documentation with size limits (≤50KB)
4. Output — README_AI.md optimized for AI consumption, or JSON for tool integration
