fetch-source

name	fetch-source
description	Fetch source code for npm packages, Python packages, Rust crates, or GitHub repos to understand their implementation. Use when you need to explore a library's internals.

Fetch Source Code

Use opensrc to download and explore package source code.

Commands

npx opensrc <package>           # npm package (e.g., npx opensrc zod)
npx opensrc pypi:<package>      # Python package (e.g., npx opensrc pypi:requests)
npx opensrc crates:<package>    # Rust crate (e.g., npx opensrc crates:serde)
npx opensrc <owner>/<repo>      # GitHub repo (e.g., npx opensrc vercel/ai)

Rules

• Always run in /tmp to avoid cluttering working directory
• Use when you need to understand library internals, not just API surface
