The model-refusal fallback setting is now an explicit 'switch automatically' vs 'ask each time' choice, promptable interactively, with new telemetry

What

  • The /config setting switchModelsOnFlag (whether Claude Code automatically switches to a fallback model when the current model refuses/flags a request) is now an explicit enum of 'switch automatically' or 'ask each time', rather than a plain boolean, though it still accepts true/false/on/off/yes/no from the CLI or config files.
  • When a model refuses or flags a request and Claude Code wants to switch to a fallback model, it can now ask interactively with a question like "Switch to ... and keep going whenever this happens?", offering to switch automatically or pause, and remembers the choice.
  • Changing this setting now fires a tengu_refusal_fallback_setting_changed telemetry event and persists the change to user settings.
  • New telemetry events were registered: tengu_refusal_fallback_preference_prompt, plus tengu_policy_limits_cache_state_at_first_prompt and tengu_policy_limits_fetch.

Why This gives users more explicit control over automatic model fallback on refusal, letting them decide in the moment (and remember the choice) rather than relying on a single fixed setting.
