Make structured product decisions with clear rationale. Use this skill whenever the user needs to decide between options, says 'help me decide', 'which option', '做决策', '选哪个', '方案对比', 'trade-off', or presents two or more alternatives. Also trigger when the user says 'should we do X or Y', 'what's the right approach', or 'I'm not sure about X'. Even statements like 'let's go with A' should trigger this to ensure the decision is documented with rationale.
