What
The Agent tool is what Claude uses to hand work to a subagent, a separate helper that works on part of a task. Claude Code builds the tool's description from options, and the option that listed the costs of delegating first has been removed. Another option for a shorter rewrite of the description now uses a different switch.
Why
The Agent tool description captured under this release is the same length as the previous capture, so this does not show up as a change in that wording.
