## What it is
opensrc is a Rust-based CLI that fetches and caches the source code of packages from npm, PyPI, crates.io, and GitHub so AI coding agents can read real implementations. It exposes an `opensrc path` command that returns a local cached path usable in subshells with tools like rg, cat, and find.

## Use cases
- give my AI coding agent access to a package's actual source code
- search npm package source with ripgrep
- fetch and cache source code from pypi or crates.io
- read implementation files instead of just type definitions
- feed real dependency source into LLM context

## When to choose
- you use AI coding agents that benefit from reading dependency implementations
- you want a fast cached way to browse package source across registries
- you script source exploration with rg/grep/cat in subshells

## When to avoid
- you only need type definitions or documentation, not source
- you need a GUI-based package browser
- you work offline with no registry or git access
