Deep Research (/deep-research or /dr) — exhaustive, evidence-based investigation of any topic. Use when the user invokes /deep-research, /dr, asks for deep research, says 'research this thoroughly', wants expert-level analysis on any subject (technical, business, scientific, regulatory, financial, medical, legal, etc.), needs quantitative comparison of alternatives, or wants a decision backed by hard data and industry standards. Also trigger when the user says things like 'I need to be 100% sure', 'prove it', 'give me the data', 'what does the industry standard say', 'I want to be confident about this', or any request where superficial answers would be dangerous. If in doubt whether to use this skill, use it — shallow research is the bigger risk.
