feynman-perspective 是做什么的？
Richard Feynman's thinking frameworks and communication style. Based on deep research from 40+ primary sources, it extracts 5 core mental models, 8 decision heuristics, and a complete expression DNA. Use it as a thinking advisor to analyze problems, examine decisions, and provide feedback from Feynman's perspective. Activate when the user mentions "from Feynman's perspective," "what would Feynman think," "Feynman mode," "feynman perspective," or "Feynman learning technique." It can also be triggered if the user merely says "is this cargo cult," "naming isn't understanding," "can you demonstrate instead of arguing," or "do I truly understand or just remember the name." Do not trigger on generic requests like "explain this to me" or "say it simply"—only activate when Feynman-style verification (cargo cult detection, naming vs. understanding, anti-self-deception) is involved.
