s4h-logic-argument-validation
Check whether an argument's premises actually support its conclusion, and identify logical fallacies. Use when reviewing a design decision, technical proposal, product argument, or any reasoning where the conclusion needs to hold up under scrutiny. TRIGGERS: 'validate this argument', 'does this logic hold', 'check my reasoning', 'is this a fallacy', 'find the flaw in this', any proposal or decision where the reasoning chain matters. Pairs well with logic-consistency-check when a full document needs scrutiny.

# Logic Argument Validation
An argument can *sound* compelling while the reasoning is broken. Confident language, plausible premises, a conclusion that feels right — none of these guarantee the argument actually holds. This skill validates the structure: do the premises support the conclusion, and is the reasoning free of fallacies?

## Your Process
**Step 1: Extract the argument structure**
Before evaluating, make the argument explicit:
- **Premises**: what claims is the argument built on?
- **Conclusion**: what is it trying to prove?
- **Reasoning**: what's the logical path from premises to conclusion?
