Aod Lens

Routes to 14 structured thinking methodologies (lenses) for systematic analysis. Use this skill when you need to think through problems, apply thinking lenses, reason through decisions, or perform systematic analysis. Auto-selects appropriate lens based on context - 5 Whys for failures, Pre-Mortem for risks, First Principles for assumptions, Systems Thinking for architecture, Four Causes for understanding, Cargo Cult Detection for validation, Golden Mean for calibration. Use when this capability is needed.

Thinking Lens Skill

Router that selects and applies thinking methodologies from docs/core_principles/.

"how much", "balance", "calibrate", "sweet spot", "too much", "too little", "spectrum"	Golden Mean	`14-GOLDEN_MEAN.md`

Workflow

Route: Match user keywords to lens using table above
Load: Read full methodology from docs/core_principles/[FILE]
Apply: Follow the step-by-step process and use template from that file

If ambiguous, ask:

"Would you like to focus on risks (Pre-Mortem), root cause (5 Whys), or trade-offs (Opportunity Cost)?"

Quick Reference

Problem Type	Lens
Something failed	5 Whys
Planning something risky	Pre-Mortem
Choosing between options	Comparative Analysis
Understanding a system	Systems Thinking
Prioritizing work	Pareto Analysis
Understanding why something exists	Four Causes
Checking if a practice is actually working	Cargo Cult Detection
Finding the right balance/amount	Golden Mean
Not sure	Pre-Mortem (safest default)

Hand-offs

Situation	Route To
Need to fix code after analysis	`debugger` skill
Document root cause in KB	`retrospective` skill
Security issue found	`security-pattern-scanner` skill
