Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Understand Codebase Analyze application architecture, patterns, and how everything works together. ## Analysis Phases **1. Project Discovery** - Use Glob to map entire project structure - Read key files (README, docs, configs) - Use Grep to identify technology patterns - Read entry points and main files Discover: - Project type and main technologies - Architecture patterns (MVC, microservices, etc.) - Directory structure and organization - Dependencies and external integrations - Build and deployment setup **2. Architecture Analysis** - **Entry points**: Main files, index files, app initializers - **Core modules**: Business logic organization - **Data layer**: Database, models, repositories - **API layer**: Routes, controllers, endpoints - **Frontend**: Components, views, templates - **Configuration**: Environment setup, constants - **Testing**: Test structure and coverage **3. Pattern Recognition** - Naming conventions for files and functions - Code style and formatting rules - Error handling approaches - Authentication/authorization flow - State management strategy - Communication patterns between modules **4. Dependency Mapping** - Internal dependencies between modules - Exter

What does the understand skill do?
Use when user asks "what does this codebase do", "explain the architecture", "how does this project work", "analyze this repo", "understand the code", or wants to learn how an unfamiliar codebase is structured.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill understand --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
