sdd

What problem does it solve?

This Skill eliminates the tedious manual work of writing software specifications, which are often inconsistent and disconnected from implementation. It automates the creation of executable specifications, bridging the gap between intent and code. This significantly reduces manual effort in project planning and development, helping teams build faster, with higher quality, and less ambiguity.

Core Features & Use Cases

• Greenfield Project Setup: Guides you from initial concept to a fully specified and implemented new project.
• Brownfield Codebase Modernization: Reverse-engineers existing code into SDD format, enabling you to add new features or modernize legacy systems with clear, AI-generated specifications.
• Automated Artifact Generation: Automatically creates project constitutions, detailed specifications, technical plans, and task breakdowns, summarizing each for your review and feedback.
• Use Case: Starting a new web application? Use this Skill to define your project's principles, specify features, plan the technical architecture, and break it into actionable tasks, all with AI guidance and automated documentation.

Quick Start

To start a new project called 'my-app' using Spec-Driven Development:

1. Install the specify-cli tool: uv tool install specify-cli --from git+https://github.com/github/spec-kit.git
2. Initialize your project: specify init my-app --ai claude
3. Then, in your AI agent, define your project's principles: /speckit.constitution Create principles for a production-ready web app focusing on scalability and security.
