SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires sdd, problem-frames, spectra-amplifier, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill tackles the challenge of converting fuzzy requirements into detailed, executable, and testable specifications, providing a structured approach to software development documentation.

Core Features & Use Cases

  • Multi-Layer Specification Expansion: Integrates Spec Kit's five-level specification methodology with OpenSpec/Spectra's change management framework.
  • Behavioral Specification Generation: Automatically generates Gherkin scenarios for user stories and acceptance criteria.
  • Test Plan and Coverage Analysis: Assists in creating comprehensive test plans and performing coverage analysis.

Quick Start

Run the spectra-amplifier skill and provide a User Story or feature description to generate a detailed specification.

Frequently Asked Questions about spectra-amplifier

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

FAQPage Schema
How do I generate detailed specifications from vague user stories?▼

Generating detailed specifications from vague user stories requires automating multi-layer specification expansion to transform fuzzy requirements into structured, testable software development documentation.

How do I automatically generate Gherkin BDD scenarios for acceptance criteria?▼

Automatically generating Gherkin BDD scenarios for acceptance criteria involves parsing user stories and mapping requirements directly into structured Given-When-Then formats for behavioral specification testing.

What is multi-layer specification expansion in software development?▼

Multi-layer specification expansion in software development is a methodology that integrates five-level specification frameworks with change management systems to ensure traceability from initial requirements to final tests.

Does this specification generation approach require Python to run?▼

Yes, this specification generation approach requires Python to run, and it optionally integrates with the 'sdd' plugin to enhance structured software design and change management workflows.

What is the best way to create comprehensive test plans from feature descriptions?▼

The best way to create comprehensive test plans from feature descriptions is to use automated coverage analysis tools that map generated behavioral specifications directly to test execution requirements.

When should I use change management frameworks for software requirement traceability?▼

You should use change management frameworks for software requirement traceability when converting fuzzy requirements into executable specifications, ensuring that all generated test plans align with evolving user stories.
