grepo

Guide for working with grepo, a Rust CLI that manages project-local read-only reference repositories. Use this skill whenever a project contains a `.repos/` directory (or legacy `grepo/`) with a `.lock` file, when entries under `.repos/` appear as symlinks into a shared cache, when the user mentions grepo / `grepo add` / `grepo sync` / `grepo update`, or when you notice that code you are reading lives inside a read-only snapshot tree under `.repos/`. Explains the commands, the lockfile, sources (git URL / npm / cargo), and what the symlinked trees actually are.

Delegate repo-grounded research to a subagent using grepo-managed snapshots. Use when the user says to run a grepo subagent, have a subagent inspect a project in `.repos/` (or legacy `grepo/`), or answer a research question against code already pinned under a `.repos/` alias.
