understand-anything — Codebase Understanding

• Trigger: /understand-anything commands
• Best for: New project onboarding, codebase exploration, architecture analysis
• Not for: Small file edits, already-familiar projects

Overview

understand-anything is a suite of codebase understanding and knowledge graph tools with multiple sub-skills:

Sub-Skill	Function
understand	Analyze codebase to produce interactive knowledge graph
understand-onboard	New developer onboarding guide
understand-explain	Explain code structure and relationships
understand-chat	Conversational exploration via knowledge graph
understand-domain	Extract business domain knowledge
understand-diff	Analyze change impact
understand-dashboard	Visual knowledge graph dashboard
understand-knowledge	Query the knowledge graph

Trigger Conditions

• Mention "analyze code", "understand project", "onboard"
• Use /understand-anything commands

Examples

Example 1: Project Onboarding

/understand-anything:understand-onboard

Claude will:

1. Scan project structure
2. Identify architectural layers and core modules
3. Generate visual knowledge graph
4. Create guided learning path

Example 2: Architecture Analysis

/understand-anything:understand Analyze the entire project architecture and module dependencies

Example 3: Change Impact Analysis

/understand-anything:understand-diff Analyze the impact scope of this PR

Example 4: Business Domain

/understand-anything:understand-domain Extract business domain knowledge for the payment module

Example 5: Interactive Dashboard

/understand-anything:understand-dashboard Launch the knowledge graph visualization

How It Works

1. Scan — file-analyzer processes all source files
2. Parse — Extract symbols, dependencies, and architectural layers
3. Graph — Build knowledge graph (nodes = files/symbols, edges = relationships)
4. Interact — Explore via dashboard or conversation

Notes

• Requires codegraph init -i to initialize the index first
• First analysis on large projects takes time
• Knowledge graph auto-updates after code changes
