The Physicist Analyst skill empowers Claude to evaluate events, technologies, and systems through a rigorous scientific lens, applying core principles like thermodynamics, conservation laws, and dimensional analysis. It is specifically designed for assessing energy systems, determining physical constraints, and performing feasibility studies where qualitative reasoning is insufficient. By grounding its analysis in first principles—such as entropy, mass-energy equivalence, and electromagnetism—this skill helps users distinguish between engineering challenges and hard physical limits, ensuring that proposed solutions are scientifically sound and scalable.
