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.

✨ Features

Explore the structural graph

Navigate your codebase as an interactive knowledge graph — every file, function, and class is a node you can click, search, and explore. Select any node to see plain-English summaries, relationships, and guided tours.

Understand business logic

Switch to the domain view and see how your code maps to real business processes — domains, flows, and steps laid out as a horizontal graph.

🧭 Guided Tours Auto-generated walkthroughs of the architecture, ordered by dependency. Learn the codebase in the right order.	🔍 Fuzzy & Semantic Search Find anything by name or by meaning. Search "which parts handle auth?" and get relevant results across the graph.
📊 Diff Impact Analysis See which parts of the system your changes affect before you commit. Understand ripple effects across the codebase.	🎭 Persona-Adaptive UI The dashboard adjusts its detail level based on who you are — junior dev, PM, or power user.
🏗️ Layer Visualization Automatic grouping by architectural layer — API, Service, Data, UI, Utility — with color-coded legend.	📚 Language Concepts 12 programming patterns (generics, closures, decorators, etc.) explained in context wherever they appear.

🚀 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

🔧 Under the Hood

Multi-Agent Pipeline

The /understand command orchestrates 5 specialized agents, and /understand-domain adds a 6th:

Agent	Role
project-scanner	Discover files, detect languages and frameworks
file-analyzer	Extract functions, classes, imports; produce graph nodes and edges
architecture-analyzer	Identify architectural layers
tour-builder	Generate guided learning tours
graph-reviewer	Validate graph completeness and referential integrity (runs inline by default; use --review for full LLM review)
domain-analyzer	Extract business domains, flows, and process steps (used by /understand-domain)

File analyzers run in parallel (up to 5 concurrent, 20-30 files per batch). Supports incremental updates — only re-analyzes files that changed since the last run.
