SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

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

Core Features & Use Cases

  • 12-dimension decomposition: User Types, Input Extremes, Timing, Scale, State Transitions, Environment, Error Cascades, Authorization, Data Integrity, Integration, Compliance, Business Logic.
  • Simple and Deep mode: quick surface vs. subagent-backed deep analysis when planning complex changes.
  • Output-ready scenarios: structured table with dimension, scenario, severity, and expected behavior.

Quick Start

Describe a feature or plan item to generate 3–5 scenarios per applicable dimension.

Frequently Asked Questions about vc-scenario

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I identify edge cases and testing targets before coding a feature?▼

To identify edge cases before coding, you can decompose the feature across 12 dimensions like User Types, Input Extremes, and State Transitions to surface risks and generate structured testing scenarios.

What is feature decomposition for risk analysis and scenario generation?▼

Feature decomposition for risk analysis breaks a planned code path into 12 dimensions, such as Scale, Timing, and Error Cascades, to systematically surface hidden risks and output a structured table of testing scenarios.

How do I generate test scenarios for design reviews and pre-implementation testing?▼

You generate test scenarios for design reviews by describing the feature or plan item, which then produces 3 to 5 structured scenarios per applicable dimension, including severity and expected behavior.

Does this scenario generator support deep analysis for complex feature planning?▼

Yes, the scenario generator supports a Deep mode that utilizes subagent-backed analysis for complex feature planning, alongside a Simple mode for quick surface-level edge case discovery.

What are the limitations of using dimension-based decomposition for QA testing?▼

Dimension-based decomposition requires a clearly defined feature or plan item as input and generates 3 to 5 scenarios per applicable dimension, meaning highly ambiguous features may yield less actionable testing targets.

Can I use this for compliance and data integrity testing scenarios?▼

Yes, you can use this for compliance and data integrity testing as the 12-dimension decomposition explicitly includes these categories to ensure structured risk analysis and scenario generation across software projects.
