Agent Skills: external-repo

Use whenever you decide you need to inspect a third-party repo's source on disk — explicit (user pastes a repo URL asking about its contents, "how is X implemented in library Y") or implicit (you yourself proposing mid-conversation to fetch an OSS project to investigate). Managed via ghq for direct Read/Grep. DO NOT USE for one-off doc/raw-file lookups (WebFetch) or work inside the user's own repo.
