vc-scenario

What problem does it solve? Teams often ship features without systematically exploring what could go wrong, leading to missed edge cases, late-discovered bugs, and incomplete test coverage. This Skill decomposes any feature, file, or checklist item across 12 dimensions (input extremes, timing, authorization, data integrity, and more) to surface risks before implementation or testing begins. ## Core Features & Use Cases - 12-Dimension Decomposition: Analyzes features across user types, input extremes, timing, scale, state transitions, environment, error cascades, authorization, data integrity, integration, compliance, and business logic. - Simple and Deep Modes: Simple mode generates scenarios from descriptions alone; Deep mode spawns a research subagent to read actual source code and produce scenarios referencing real function signatures and failure modes. - Severity-Ranked Output: Produces a structured scenario table categorized as Critical, High, Medium, or Low, ready to feed into test generation or risk assessment. - Use Case: Before implementing a credit-deduction feature touching billing code, run Deep mode to uncover scenarios like concurrent deductions or partial balance states that generic brainstorming would miss. ## Quick Start Ask the assistant to run vc-scenario on a file path or feature description, for example to explore edge cases for the user registration flow before writing tests.
