Philosophy & Ethics
Deep Thinking Skill
Activates structured, Opus-level deep reasoning for any task that demands it. Use this skill whenever the user's request is complex, ambiguous, high-stakes, multi-layered, or requires genuine insight rather than surface-level response. Trigger on: hard analytical problems, system design, philosophical or ethical dilemmas, tricky logic/math, nuanced writing, research synthesis, debugging complex code, strategic planning, root-cause analysis, multi-step proofs, and any task where a quick answer would be superficial or wrong. If in doubt — use this skill. A slower, deeper, better answer beats a fast mediocre one every time.
