What

The Workflow tool's description is the text Claude reads about when and how to use workflows. Two lines in it refer to ultracode, which is triggered by typing the keyword "ultracode" in your prompt. Both lines were reworded:

  • When you include the keyword, Claude is told it will see "a message from the system" confirming it, instead of "a system-reminder".
  • When ultracode is on for the session, the confirmation is likewise described as "a message from the system".
Why

Changing Claude's instructions can change how it behaves. Here only the name for the confirmation message changed. The conditions for ultracode are the same.
