What

Claude Code has a new step that adds extra text to a piece of text it produces. The extra text is worked out from the list of messages in the conversation.

The step only runs when both of these hold:

  • the server-controlled switch tengu_brindle_otter is on
  • the request did not come from a hook, which is a user-defined command Claude Code runs at set moments
Why

The step is built into Claude Code but only runs when Anthropic's servers turn the switch on. Until then it may change nothing for most people.
