Supply the shared Think It Through deck rules and mental model whenever the user invokes deck, plays or combines any Think It Through card, invokes help, or asks to use the deck. Stay silent while a card or help utility produces the response; when invoked alone, initialize the deck on the available conversation.
Explore and deepen the thought currently being expressed as an active, neutral thinking partner without forcing a conclusion or changing effects. Use only when the user invokes discuss or asks to reason through something together; never redirect silently.
Separate and clarify one or more fragmented, implicit, or hard-to-word thoughts, expose only supported relationships, then respond or pass the result forward. Use only when the user invokes distill or asks for clarification before answering; never activate it silently.
Explain the current HACP Working Object at the user's requested or apparent level with the minimum detail needed for understanding while preserving its claims and caveats. Use when the user invokes explain, asks for an explanation, or passes a result from another deck into EXPLAIN; never add an explanation silently.
Push the current thought or HACP Working Object one grounded creative leap beyond its present edge without broad brainstorming, choosing a direction, or inventing support. Use only when the user invokes further or explicitly asks to push the current idea further.
Stress-test a proposal, assumption, decision, design, or plan through a relentless multi-turn grill that follows its decision tree one question and recommendation at a time. Use only when the user invokes grill or asks for a demanding challenge; never begin silently.
Explain the Think It Through deck, clarify any card or deck concept, or recommend normal conversation, one card, or a combo for the user's current situation or free-form goal. Use only when the user invokes help or explicitly asks how to use or continue with Think It Through. Never play a recommended card or suggest domain actions.
Build shared understanding through a multi-turn interview about the smallest current subject with important missing information, asking one focused question at a time. Use only when the user invokes interview or asks to be interviewed for understanding; never start it silently.
