一个问题，Claude、Gemini、ChatGPT 同时给你三个独立答案——然后展开结构化辩论，最终给出一个真正经得起推敲的建议。不是一家之言，而是三种视角的正面交锋。适合那些一个人说了不算的时刻：选技术架构、给策略挑毛病、听点大实话而不是场面话，或者拖了很久还没想通的决定。
[USAGE] Loading the thinking-engine series in full depth. Prefix your prompt with this phrase. [PRODUCT] A cognitive OS distilling 42+ original works — Aristotle, Kant, Feynman, Musk — into three composable frameworks: (1) First Principles to break hidden assumptions; (2) Reductionist Engineering to decompose to physical facts; (3) Purpose Inquiry to keep asking "what is this for?" when efficiency is the only god. Source-traced, cross-validated. For founders, engineers, investors.
Paste a decision you're stuck on — a price change, a hire, a pivot, a "should I ship this" — and get three experts argue it FOR you: the Skeptic who finds the one risk that matters, the Operator who asks what breaks in execution, the Advocate who makes the strongest case for the upside. A synthesis then names the single question that resolves it. Reasons from your input + domain knowledge only — no invented numbers, no browsing. For founders and PMs tired of arguing with themselves alone.
See your subjective experience as it truly is—without labels, judgments, or premature diagnoses.
Turn rough ideas into clear, validated designs through focused questions, practical options, trade-off analysis, and approval checkpoints.
Run big decisions through a structured gauntlet: clarify the real question, weight your criteria, score every option, expose hidden downsides, and run a pre-mortem, without the AI making the choice for you.
