First Principles Decision
Make sure to use this skill whenever a decision is being made by convention without examining why, a proposed solution feels unnecessarily complex, the team is adopting an industry standard without verifying fit, challenging 'that's how it's always done' assumptions, or stripping inherited constraints from a problem — even if the request is about 'decision-making' or 'problem-solving' rather than explicitly about first principles.
