Data Science

Comprehensive startup idea validation and market analysis tool. Use when users need to evaluate a startup idea, assess market fit, analyze competition, validate problem-solution fit, or determine market positioning. Triggers include requests to "validate my startup idea", "analyze market opportunity", "check if there's demand for", "research competition for", "evaluate business idea", or "see if my idea is viable". Provides data-driven analysis using web search, market frameworks, competitive research, and positioning recommendations.

Validate inference chains step-by-step by examining whether each logical connection from premise to conclusion is sound, making implicit reasoning steps explicit and checking for gaps or leaps. Use when: (1) asked to validate reasoning steps, trace the logic, or verify if conclusions follow from premises, (2) arguments skip intermediate inferential steps or use 'therefore' without showing the reasoning path, (3) evaluating multi-step proofs, mathematical reasoning, or decision frameworks where each step builds on previous ones, (4) reasoning depends on unstated assumptions being treated as established facts.

Generate and compare multiple architecture options (minimal, moderate, full modernization) with comprehensive trade-offs analysis across cost, timeline, risk, performance, and maintainability dimensions. Use when evaluating multiple architectural approaches or deciding between modernization strategies with different cost/risk trade-offs.

Analyzes bull-call-spread debit spreads for bullish directional plays with defined risk. Requires numpy>=1.24.0, pandas>=2.0.0, matplotlib>=3.7.0, scipy>=1.10.0. Use when expecting moderate price increase, comparing vertical spread configurations, analyzing debit spread opportunities, calculating Greeks for multi-leg positions, or evaluating defined-risk bullish strategies on liquid optionable securities.

This skill should be used for Python idioms, type hints, async/await, pytest, Django, Flask, FastAPI, Python web frameworks, pandas, data processing
