vc:scenario — Edge Case & Scenario Explorer

Decompose any feature or code path across 12 dimensions to surface edge cases, risks, and test targets before implementation begins.

When to Use

• Before implementing complex or stateful features
• Before writing tests (generates test targets)
• Risk assessment during planning or code review
• API design review — surface contract edge cases early

When NOT to Use

• Trivial single-line changes or cosmetic UI tweaks
• Already well-tested, stable code with no recent modifications
• Pure configuration changes with no logic paths
