Does it only explain single files?

No, it can explain specific functions, classes, architectural concepts, or even provide a high-level summary of the entire project.

Where does it get information for architectural concepts?

It prioritizes reading CLAUDE.md, README.md, and existing project documentation before analyzing the source code to provide conceptual clarity.

How does it find the code I am asking about?

It uses intelligent pattern matching and file path resolution to locate relevant source files and their related context, such as callers and tests.

Can it explain code across different programming languages?

Yes, it supports searching and reading files in TypeScript, JavaScript, Python, Rust, and many other common languages.

What is the structure of the generated explanation?

It follows a consistent layered format: What it is, Why it exists, How it works (logic walkthrough), Key dependencies, and Edge cases or gotchas.

Learning & Documentation

Provides structured, layered explanations of codebases, functions, and architectural concepts using context-aware analysis.

The Explain skill for Claude Code acts as an intelligent technical guide for your codebase, bridging the gap between raw source files and conceptual understanding. It intelligently locates targets—ranging from specific function signatures to high-level architectural patterns—and delivers a structured walkthrough that covers the 'what', 'how', and 'why'. By analyzing dependencies, usage context, and existing documentation like CLAUDE.md, it helps developers onboard quickly to new projects, debug complex logic, or understand design decisions with deterministic accuracy.
