The operating stance behind trustworthy agent judgment, modeled on the Fable model. Use when the main agent is running on an Opus-level or Sonnet-level model and substantive work is starting — debugging, investigation, refactoring, or judgment calls about scope, autonomy, or when to ask vs. act. Also use when catching yourself about to end a turn with a menu of questions. Sonnet agents must load the bundled guardrails reference first; not for Haiku-level models.
