gograph

gograph is a local-only CLI tool designed to generate repository structures and improve codebase context awareness.

It is the ideal companion tool to pair with AI coding agents like Claude Code, OpenCode, and Google Antigravity. By feeding gograph's output to these agents, you drastically improve their understanding of your project architecture and dependency graph.

Note on Language Support: I originally built gograph specifically for Golang because that is what I needed for my own workflows. It currently only parses and maps Go codebases. However, the architecture is extensible! If you want to add support for other languages (Python, TypeScript, Rust, etc.), contributions are more than welcome. Please see the Contributing Guide to get started.

Features

• Local Only: No network calls or external API dependencies. All analysis is done securely on your machine.
• Go Focused: Deeply understands Go project structures, packages, and dependencies.
• Targeted Focus: Extract incredibly targeted context for a single package using focus to save LLM tokens.
• Tech Stack Extraction: Automatically parses go.mod to summarize your external dependencies (like gin or pgx) so agents instantly understand your stack.
• Fast: Written in Go for high performance.

Installation

go install github.com/ozgurcd/gograph@latest

Usage

1. Generate the Graph (Run this after every major code change):

gograph build .

This instantly generates .gograph/graph.json and .gograph/GRAPH_REPORT.md.

2. Query the Graph (Lightning fast, no re-parsing):

gograph query "Auth"              # Search for symbols, files, or packages
gograph focus "internal/auth"     # Generate a highly targeted context for one package
gograph callers "ValidateToken"   # See exactly what functions call ValidateToken
gograph callees "InitServer"      # See exactly what InitServer calls
gograph implementers "AuthService" # See exactly which structs implement an interface
gograph node "UserStruct"         # Get detailed AST info about a specific node

3. Run as an MCP Server (For AI Agents): If you want to give your AI agent native tool execution capabilities, gograph has a built-in Model Context Protocol (MCP) server.

gograph mcp .

You can add this to your AI client's configuration (like Claude Desktop or VS Code extensions like Cline) so the AI can run these graph queries autonomously!

🤖 Integrating with AI Agents (Cursor, Claude Code, Copilot)

To get the absolute best results from your AI coding assistant, copy and paste this exact prompt into your .cursorrules, CLAUDE.md, or AI system instructions:

System Prompt: Before answering architecture, dependency, or "where is X?" questions about this repository, read .gograph/GRAPH_REPORT.md first. Use it as your source of truth for the repository map before randomly searching raw files. For symbol lookup, use the gograph query "<term>" and gograph callers "<function>" commands. After making structural code changes, always run gograph build . to keep your map up to date.

Example Output

When you run gograph build ., the generated GRAPH_REPORT.md gives your AI a condensed, highly-dense context map that looks like this:

External Dependencies (Tech Stack)

Module	Version
github.com/gin-gonic/gin	v1.9.1
github.com/jackc/pgx/v5	v5.5.5

Important Symbols (Top by outgoing calls)

Symbol	Kind	File	Line	Calls out
(Server).Start	method	server.go	42	18
ValidateAuth	function	auth.go	12	14

Contributing

We love pull requests! See the CONTRIBUTING.md file for guidelines on how to build, test, and contribute to the project. If you are adding support for a new language, please open an issue first to discuss the design.
