# Study Sources

> Fetch and read real upstream source code — from Git hosts (GitHub/GitLab/Bitbucket) and from installed dependencies (nodemodules, ~/.m2, Gradle/Android SDK sources, Go/Rust/.NET/Ruby/PHP/Swift/Dart caches) — into a gitignored .scratch/ so you build knowledge from actual code instead of guessing at APIs. Use when a task depends on how a library, framework, package, or SDK actually behaves, when reading a dependency's implementation or types would remove guesswork, when reproducing an upstream bug, or when the user asks to pull down / study / vendor a repo or package source. Reads are read-only and never enter the repo's own git history.
