Two model behaviours, a silent turn reminder and a Bash-output audience note, can be forced on by env vars.
What's wrong with this entry?
A silent turn reminder and a new note telling Claude who will read Bash output now resolve the same way: an environment variable wins, then whatever the model catalog declares, then a cached blob of settings the server delivers. Anything else is off. In practice both are off unless the server enables them or you set CLAUDE_CODE_SILENT_TURN_REMINDER or CLAUDE_CODE_BASH_OUTPUT_AUDIENCE_NOTE yourself.
- The silent turn reminder previously came from a per-model experiment lookup; that path is gone.
- The first time a given model takes a capability from the server payload it reports it once, tracked with a small cache of recently seen models.
