What probably matters to youSection of the release

Unclear What the "compact-held" mode does differently from "compact" is not settled.

What

In auto mode, Claude Code picks a mode for how it asks questions in a thread. It used to choose between "compact" and "original". It now chooses between:

  • "compact-held", when the environment variable CLAUDE_CODE_AUTO_MODE_THREAD_ASK_HELD is set or the server flag tengu_projects_thread_ask_held_killswitch is on
  • "compact", in every other case

An environment variable is a named value you set in your shell before starting Claude Code.

Why

This adds a held form of compact mode for questions asked in auto mode, and gives both you and the server a way to switch it on.
