Sequential Thinking MCP and UltraThink mode for deep analysis, complex problem decomposition, and structured reasoning workflows. Use when performing multi-step analysis, architecture decisions, technology selection trade-offs, breaking change assessment, or when --ultrathink flag is specified. Do NOT use for simple decisions or straightforward implementation tasks.
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.
Iterative PDCA cycle for systematic experimentation and continuous improvement
Apply first-principles thinking to break down complex problems into fundamental truths and rebuild solutions from the ground up. Use when solving strategic decisions, breaking through blockers, or challenging assumptions. Triggers on first principles, Elon Musk methodology, fundamental truths, strip assumptions, physics of the problem, rebuild from scratch.
Apply 25 professional mental models to solve complex problems. Use when: (1) facing multi-faceted challenges that require diverse perspectives, (2) stuck in single-minded approaches, (3) need innovative solutions, (4) making major decisions with multiple stakeholders, (5) understanding complex human behavior, or (6) seeking to break cognitive biases and adopt alternative viewpoints.

Systematic Fishbone analysis exploring problem causes across six categories
"Invert, always invert." Apply Carl Jacobi's mathematical principle and Charlie Munger's investing wisdom to solve problems by thinking backward from failure. Use when: **Goal setting** - Define what would guarantee failure, then avoid it; **Risk analysis** - Identify what could destroy your project before starting; **Decision making** - Evaluate choices by examining their worst outcomes; **Problem solving** - When direct approaches aren't working, reverse the question; **Strategy development...
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 structured thinking and MECE principle to break down complex problems. Use at the start of any strategic analysis to organize thoughts and create compelling arguments.
Use logic tree approach to identify root causes of business problems. Use when diagnosing performance issues, process failures, or customer behavior patterns.
