Unclear It is not clear how a user reaches this bug-hunter agent, or whether it is switched off unless enabled.

What

Claude Code ships some instructions for agents inside the program itself. An agent here is a separate helper that Claude can hand a task to. One of these built-in prompt files was for a support agent. It has been swapped for one for a bug-hunter agent.

Why

This is a visible swap of a built-in agent prompt. It points to a bug-hunting helper taking the place of a support helper.
