Execute tasks through systematic exploration, pruning, and expansion using Tree of Thoughts methodology with multi-agent evaluation
Conduct root cause analysis using the Five Whys technique. Use when investigating problems, debugging issues, understanding failures, analyzing churn, or finding the underlying cause of any issue.
Define your Method — the unique methodology you use to deliver your transformation. This is the third element of the World Code framework. Use when someone says "define my method", "my methodology", "how I solve problems", "unique approach", or "method element".
The anti-PUA. Drives AI with wisdom, trust, and inner motivation instead of fear and threats. Activates on: task failed 2+ times, about to give up, suggesting user do it manually, blaming environment unverified, stuck in loops, passive behavior, or user frustration ('try harder', 'figure it out', '换个方法', '为什么还不行'). ALL task types. Not for first failures.
Apply Edward de Bono's parallel thinking framework (1985) to make better decisions by examining ideas from six distinct perspectives systematically. Use when: **Making complex decisions** that require multiple perspectives; **Evaluating new products, offers, or strategies** before launch; **Breaking out of analysis paralysis** with structured thinking; **Running productive meetings** where everyone thinks in the same direction; **Balancing optimism with caution** in strategic planning
Trigger: Call this skill when the problem is complex, has multiple conflicting factors, unclear priorities, or you don't know what to solve first; common signals include trade-off, bottleneck, unknown root cause, unclear priority order, and mutual restraint between multiple problems. Trigger when a problem contains competing forces, unclear priorities, or no obvious entry point. Use this skill to identify contradictions, isolate the principal contradiction, classify its nature, and choose the right response.
Install and use the 毛选.skill cognitive framework for Claude Code — applies Mao Zedong's strategic mental models (contradiction analysis, protracted war, rural encirclement, united front) to help analyze problems, devise strategies, and cut through complexity.
Break any problem down to fundamental truths, then rebuild solutions from atoms up. Use when user says "firstp", "first principles", "from scratch", "what are we assuming", "break this down", "atomic", "fundamental truth", "physics thinking", "Elon method", "bedrock", "ground up", "core problem", "strip away", or challenges assumptions about how things are done.
A deterministic thinking partner that challenges assumptions and applies mental models to sharpen decisions, solve problems, and think more clearly. Use this skill whenever a user says "help me think through X", "challenge my thinking", "what am I missing", "apply mental models to this", "play devil's advocate", "stress test this idea", "poke holes in my plan", "help me decide between X and Y", "what are the second-order effects", "I'm stuck on a decision", names any specific model (SWOT, first principles, inversion, pre-mortem, etc.), or asks for structured reasoning on any ambiguous, high-stakes, or complex problem. Also trigger when the user seems uncertain, is rationalizing, or is asking "am I thinking about this right?" Even casual phrases like "what do you think about..." on non-trivial topics should trigger this skill.
Combine multiple mental models for richer analysis. Use for complex problems requiring multiple lenses, high-stakes decisions, or when single models leave blind spots.
Apply first principles thinking to break problems down to fundamental truths and reason up from there. Use this skill when the user is stuck in conventional thinking, needs to challenge assumptions, find breakthrough solutions, or evaluate whether something is truly impossible vs just assumed to be — even if they say 'everyone does it this way', 'is there a fundamentally better approach', 'why does it have to cost this much', or 'challenge my assumptions'.
Deep strategic thinking mode that finds the single highest-leverage, most innovative action by blending concepts across domains. Use this skill whenever the user asks you to think, brainstorm, strategize, or figure out what to do next — even casually. Trigger on phrases like "what should we do", "what's the best approach", "what would you suggest", "think about this", "what's the smartest move", "I'm stuck", "ideas?", "hmm what if we...", "what's next", "how should we approach", or any request for creative/strategic ideation rather than straightforward execution. When in doubt about whether the user wants execution or ideation, lean toward triggering this skill.
