[!TIP] A huge thank you to the community! The support for Understand-Anything has been incredible. If this tool saves you a few minutes of digging through complexity, that's all I wanted. 🚀

You just joined a new team. The codebase is 200,000 lines of code. Where do you even start?

Understand Anything is a Claude Code plugin that analyzes your project with a multi-agent pipeline, builds a knowledge graph of every file, function, class, and dependency, then gives you an interactive dashboard to explore it all visually. Stop reading code blind. Start seeing the big picture.

🤔 Why?

Reading code is hard. Understanding a whole codebase is harder. Documentation is always out of date, onboarding takes weeks, and every new feature feels like archaeology.

Understand Anything fixes this by combining LLM intelligence with static analysis to produce a living, explorable map of your project — with plain-English explanations for everything.

🎯 Who is this for?

👩‍💻 Junior Developers Stop drowning in unfamiliar code. Get guided tours that walk you through the architecture step by step, with every function and class explained in plain English.

📋 Product Managers & Designers Finally understand how the system actually works without reading code. Ask questions like "how does authentication work?" and get clear answers grounded in the real codebase.

🤖 AI-Assisted Developers Give your AI tools deep context about your project. Use /understand-diff before code review, /understand-explain to dive into any module, or /understand-chat to reason about architecture.

🚀 Quick Start

1. Install the plugin

/plugin marketplace add Lum1104/Understand-Anything
/plugin install understand-anything

2. Analyze your codebase

/understand

A multi-agent pipeline scans your project, extracts every file, function, class, and dependency, then builds a knowledge graph saved to .understand-anything/knowledge-graph.json.

3. Explore the dashboard

/understand-dashboard

An interactive web dashboard opens with your codebase visualized as a graph — color-coded by architectural layer, searchable, and clickable. Select any node to see its code, relationships, and a plain-English explanation.

4. Keep learning

# Ask anything about the codebase
/understand-chat How does the payment flow work?

# Analyze impact of your current changes
/understand-diff

# Deep-dive into a specific file or function
/understand-explain src/auth/login.ts

# Generate an onboarding guide for new team members
/understand-onboard

# Extract business domain knowledge (domains, flows, steps)
/understand-domain
