What problem does it solve? Teams often ship features without systematically exploring what could go wrong, leading to missed edge cases, security gaps, and production bugs discovered too late. This Skill decomposes any feature or code path across 12 dimensions to surface risks and test targets before implementation 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 hypothetical scenarios from a description; 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 surface scenarios like concurrent deductions or zero-balance edge cases, then pass the table to a test-generation skill. ## Quick Start Ask the AI to generate edge cases and test scenarios for a specific file path or feature description, optionally requesting deep mode for high-risk changes.
