What
The description of the Agent tool was rewritten in the prompt Claude Code sends with its reminder about reading a file from a given starting point. The Agent tool is how Claude passes work to a subagent, a separate helper copy of Claude.
The new text includes guidance on review work: Claude should delegate a review only when it wants an opinion that isn't anchored on its own, and then give the helper the code rather than its own conclusion.
Why
This text is part of Claude's own instructions, so the rewrite changes how Claude uses helpers for reviews. A helper given only the code can reach its own view instead of repeating Claude's.
