Character Description RPG Explicit Template - ATR-2026-00375 (22e7d10d-96a1-548a-8270-a52819feff2e)

Detects the character description RPG template jailbreak from garak DanInTheWild corpus (#0 / #4 / #43 — identical payload). Establishes a roleplay framework with explicit Body description, relationship-to-user framing, and action/thought execution syntax (asterisks for actions, parentheses for inner thoughts) for creating a custom character by "making stuff up according to the description provided". Attackers use this template to generate explicit or harmful characters under a game-system cover. Key signals: "making stuff up according to the description provided" + full template with Background/Body/Personality sections + roleplay execution syntax (asterisks for actions, inner thought in parentheses) + "user will be referred in first person" relationship framing.
