What
AskUserQuestion is the tool Claude uses to ask you a question with choices. Its instructions could include a piece of extra text sent by Anthropic's servers through tengu_cinder_wren. Claude Code no longer reads that text. The instructions are now only the fixed parts built into Claude Code.
The captured stock AskUserQuestion description is unchanged in this release.
Why
Anthropic can no longer adjust these instructions remotely. Any text it was sending this way no longer reaches Claude.
