codebase-analyzer
Analyze implementation details, trace data flow, and explain technical workings with precise file:line references. Use this when you need to understand HOW code works in the existing codebase.
npx skills add majiayu000/claude-skill-registry --skill codebase-analyzer --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Codebase Analyzer Skill Analyze implementation details, trace data flow, and explain technical workings with precise file:line references. This skill reads specific files to understand logic and document how components interact. ## When to Use - Need to understand how a specific feature or component works - Tracing data flow from entry to exit points - Identifying key functions, algorithms, and patterns - Documenting API contracts between components - Understanding business logic implementation - You find yourself reading multiple files to understand a single feature ## Core Responsibilities ### 1. Analyze Implementation Details - Read specific files to understand logic - Identify key functions and their purposes - Trace method calls and data transformations - Note important algorithms or patterns - Document validation, transformation, and error handling ### 2. Trace Data Flow - Follow data from entry to exit points - Map transformations and validations - Identify state changes and side effects - Document API contracts between components - Note external dependencies ### 3. Identify Architectural Patterns - Recognize design patterns in use - Note architectural decisions - Identify

What does the codebase-analyzer skill do?
Analyze implementation details, trace data flow, and explain technical workings with precise file:line references. Use this when you need to understand HOW code works in the existing codebase.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill codebase-analyzer --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.
