# GitLab Knowledge Graph (GKG)

Semantic code analysis engine using AST parsing and KuzuDB graph database. Enables IDE-like code navigation for AI assistants.

**Status**: Public beta | **Requires**: Git repository | **Storage**: `~/.gkg/`

## When to Use

- Find all usages of a function/class across codebase
- Go-to-definition for symbols
- Impact analysis before refactoring
- Generate architecture diagrams
- RAG-enhanced code understanding

**Use repomix instead** for: quick context dumps, any-language support, remote repos, token counting.

## Quick Start

```bash
# Check installation
gkg --version

# Index current repo
gkg index

# Start server (for API/MCP)
gkg server start

# Stop before re-indexing
gkg server stop
```

## Installation

```bash
# macOS/Linux
curl -fsSL https://gitlab.com/gitlab-org/rust/knowledge-graph/-/raw/main/install.sh | bash

# Windows (PowerShell)
irm https://gitlab.com/gitlab-org/rust/knowledge-graph/-/raw/main/install.ps1 | iex
```

## Core Workflows

### Index and Query
```bash
gkg index /path/to/project --stats
gkg server start
# Query via HTTP API at http://localhost:27495
```

### Find Symbol Usages
1. Index project: `gkg index`
2. Start server: `gkg server start`
3. Use MCP tool `get_references` or HTTP API `/api/graph/search`

### Impact Analysis
1. Index affected repos
2. Query `get_references` for changed symbols
3. Review all call sites before refactoring

## Language Support

| Language | Cross-file Refs |
|----------|-----------------|
| Ruby | ✅ Full |
| Java | ✅ Full |
| Kotlin | ✅ Full |
| Python | 🚧 In progress |
| TypeScript | 🚧 In progress |
| JavaScript | 🚧 In progress |

- [CLI Commands](./references/cli-commands.md) - `gkg index`, `gkg server`, `gkg remove`, `gkg clean`
- [MCP Tools](./references/mcp-tools.md) - 7 tools for AI integration
- [HTTP API](./references/http-api.md) - REST endpoints for querying
- [Language Details](./references/language-support.md) - Supported features per language

## Key Constraints

- Must stop server before re-indexing
- Requires initialized Git repository
- Languages not connected across repos (yet)
- TS/JS/Python cross-file refs incomplete
