Claude can narrate what it's about to do and post progress updates; set CLAUDE_CODE_TURN_UPDATES.
What's wrong with this entry?
Claude can be told to say what it is about to do before starting, post brief progress updates while working, and write a final message that stands alone. Set CLAUDE_CODE_TURN_UPDATES to turn it on or off yourself; otherwise it is decided by a per-model capability check, then by a capability map the server sends with your account data. It replaces the usual communication guidance in the system prompt rather than adding to it.
- Resolution order: the environment variable wins if set (it accepts true/false/unset), then the model capability check, then the server-supplied map.
- The env var is new in this build.
- When the value comes from the server-supplied map, a
tengu_model_capability_from_client_datatelemetry event is emitted.
CLAUDE_CODE_TURN_UPDATES=1 claudeBefore you start, say in a line what you're about to do; brief updates while you work help the user follow along. Your final message should stand on its own for a reader catching up fresh.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
