When you call via the API and want it to roleplay as a pirate or fix broken YAML in the coding harness - it doesn't need to know about the sports scores lookup tool or the recipe creation tool.

They also can't tell Opus it might be a Fable handoff when Fable didn't exist when Opus was created. They need to be able to change them.
