Do I need the Spec-Kit CLI installed to use this skill?

No, this skill provides the full SDD methodology and workflow within Claude Code even without the standalone CLI tool.

What is Specification-Driven Development (SDD)?

SDD is a methodology where specifications are the primary artifacts used to guide and generate functional implementations, ensuring code is always an expression of defined requirements.

How does the 'Test-First' article affect development?

It makes writing failing tests non-negotiable before implementation, ensuring all code is verified against requirements from the moment it is written.

What are the core artifacts generated by Spec-Kit?

The workflow generates four key Markdown files: constitution.md (principles), spec.md (requirements), plan.md (technical strategy), and tasks.md (executable steps).

生産性とワークフロー

Implements the GitHub spec-kit methodology to transform specifications into executable code through structured planning and test-driven development.

概要

Spec-Kit is a comprehensive implementation of GitHub's Specification-Driven Development (SDD) methodology designed for Claude Code. It guides developers through a rigorous 7-phase workflow—from establishing core project principles (Constitution) and defining functional requirements (Specification) to technical planning and task decomposition. By prioritizing specifications and enforcing a non-negotiable test-first implementation strategy, this skill ensures that code remains a direct, high-quality expression of well-defined requirements while significantly reducing architectural ambiguity.
