Unclear Whether a way to set the reminder mode yourself was removed is not clear.
What
The total-tokens reminder tells Claude how much of its token budget (the amount of text it can process) remains. The way it gets its settings has been reworked.
- The per-session fields
totalTokensReminderMode,totalTokensReminderBudget,totalTokensReminderAfterUserTurn,subagentBudgetOnTopOfStartandsubagentBudgetNotewere removed and replaced by a single flag,totalTokensReminderClientDataReported. - The helpers that read the reminder settings from client data were rewritten. Each setting is now reported once per session, and the remote value goes through a single path.
- The mode no longer has an explicit override layer and defaults to
padded-countdown. The budget and after-user-turn settings keep their fallbacks. - In the control group of the captured prompt, the
<total_tokens>line no longer appears in the system prompt.
Why
If you relied on setting the reminder mode explicitly, that override appears to be gone. In practice the reminder is now driven by settings sent from the service rather than by local per-session values.
