Copilot agent that assists with requirements analysis, user story creation, specification definition, and acceptance criteria definition Trigger terms: requirements, EARS format, user stories, functional requirements, non-functional requirements, SRS, requirement analysis, specification, acceptance criteria, requirement validation Use when: User requests involve requirements analyst tasks.

Choose the right level of abstraction by evaluating coupling cost versus duplication cost and change patterns. Use when: (1) asked to evaluate whether similar code should be abstracted or kept separate, (2) an extraction is suggested without analysis of whether similar pieces change together or independently, (3) an abstraction is nameable only as "common parts" rather than a domain concept, (4) justification cites aesthetics or "might need" rather than maintenance costs and change patterns.

Diagnose problems by iteratively asking 'why' to drill through symptom layers until reaching fundamental causes, using Five Whys methodology to distinguish proximate triggers from underlying conditions. Use when: (1) asked for root cause analysis, why a problem happened, or what fundamentally caused a failure, (2) explanations describe symptoms or triggers without addressing underlying enabling conditions, (3) problems recur despite fixes, suggesting earlier solutions addressed symptoms not fundamental causes, (4) transitioning from incident response to developing preventive measures that address core issues.

Analyzes iron butterfly credit spreads with ATM short straddle and OTM long strangle protection. Requires numpy>=1.24.0, pandas>=2.0.0, matplotlib>=3.7.0, scipy>=1.10.0. Use when expecting stock to pin at specific strike, want maximum credit collection in high IV, analyzing tight-range opportunities, or implementing high-premium neutral strategies on stocks with strong technical pivot levels.
