If I could install one thinking framework for someone and walk away, it would be Charlie Munger's.
His "mental models + inversion" approach catches the widest range of thinking failures across the widest range of contexts. Investing, strategy, creative decisions, leadership, writing - every domain benefits from:
→ "How would this fail?" (inversion)
→ "What am I missing because of the way I've framed this?" (mental models)
→ "What would I need to believe for this to be wrong?" (systematic doubt)

These are generalisable. Munger's framework isn't just for value investing - it's a discipline for avoiding the kind of reasoning mistakes that smart people make specifically because they're smart enough to rationalise anything.

As a Claude Skill: load it once, and Claude auto-invokes it whenever you're asking about decisions, evaluations, strategies, or things you're about to commit to. You don't have to remember to ask "but what could go wrong?" Claude asks it for you.
