[external]

Finds source usages of symbols that come from a referenced external assembly, keyed by assembly name or full metadata reference identity.

Why this tool exists

Framework and package behavior often explains local code, but the source is outside the repo.

How it helps the agent

The model can inspect external definitions and package usage evidence instead of guessing from API names.
