🧠 Skills with TypeSafe Jev Integration

Four skills now support optional integration with TypeSafe Jev — a judgment engine that provides calibrated probability assessments (Score) and categorical classifications (Noul) for subjective evaluation criteria. When Jev is available, these skills use it for nuanced quality judgments; when unavailable, they fall back to heuristic methods.

Each skill includes:

• scripts/jev_questions.json — question definitions with context requirements
• references/jev-integration.md — integration patterns and code examples
• Discovery protocol in SKILL.md — check jev_available() before use

When to use: validate a startup idea, pressure-test a business model, define the MVP, find the first customers, design the revenue model, plan go-to-market, chase product-market fit, or any variation of "I have an idea".
