Config object for a notice about a newer model in the same family as the model saved in your user settings (state keys savedModelSuccessorShown and savedModelSuccessorAnswered). The notice is suppressed when off is true, when the model's family is turned off in families (falling back to a built-in per-family default), after it has been answered, after maxViews showings, or when it was shown more recently than minDaysApart allows. The object also accepts lead, text, action and done strings; a value that fails validation counts as { off: true }.v2.1.286 ○gone never read tengu_plum_vx3 ◇ Web search tool's model choice now goes through a feature-flag check instead of always using the main modelv2.1.138 or earlier → v2.1.308 ◆in the build AND v2.1.269 tengu_policy_limits_cache_state_at_first_prompt ◇ Three new telemetry events added for refusal-fallback prompts and policy-limits checksnever mined ·never mined never read tengu_policy_limits_fetch ◇ Policy limit fetch events now record how you authenticated and why the server said no.never mined ·never mined never read tengu_policy_limits_late_composition ◇ Billing, artifact, MCP and subagent call sites also take credentials explicitly now.never mined ·never mined never read tengu_policy_limits_principal_changed ◇ Local policy-limits cache now tracks which account is logged in and reacts to account switchesnever mined ·never mined never read tengu_policy_limits_verdict_recovered ◇ Claude Code now retries faster and recovers sooner when it can't fetch your policy limitsnever mined ·never mined never read tengu_polished_dewdrop ◇ A new hidden switch, settable via env var, can make certain responses silently drop or error instead.v2.1.263 → v2.1.308 ◆in the build AND v2.1.263 tengu_polished_lagoon ◇ One session could inject a coordination notice into another, but three separate gates keep it dark.v2.1.234 → v2.1.308 ◆in the build AND v2.1.308 tengu_polished_quill_killswitch ◇ Default false. In a non-interactive session, a typed slash command that matches no command is handed to the model as an unknown_command_fallback attachment carrying the name, the closest match within edit distance 2 and up to 40 model-invocable prompt command names.
