What mental models are included in this skill?

The skill includes First Principles, Inversion, Pareto (80/20), Second Order Thinking, and the 5 Whys for structured problem-solving.

Can this skill help with documentation?

Yes, it automatically generates a structured ANALYSIS.md artifact whenever a deep analysis is requested, documenting the logic and findings.

How does the 'Evidence-First' constraint work?

Claude is prohibited from making claims without providing specific file references or shell output as proof, ensuring all analysis is grounded in the codebase.

When should I use 'The Hardening' combination?

Use 'The Hardening' (First Principles + Inversion) when working on critical security or reliability code to identify and mitigate potential failure modes.

생산성 및 워크플로

Applies proven mental models to solve complex architectural problems and conduct evidence-based root cause analysis.

The Structured Reasoning Engine (applying-reasoning) equips Claude with a rigorous framework for navigating complex technical decisions and strategic planning. By utilizing a library of mental models such as First Principles, Second-Order Thinking, and the Pareto Principle, the skill moves beyond simple coding to provide deep architectural insights. It enforces an evidence-first methodology, requiring Claude to validate assumptions via codebase research before synthesizing findings into comprehensive analysis reports, ensuring that recommendations are both logical and grounded in the actual state of the repository.
