What is a project constitution in Spec-Kit?

A project constitution is a document that establishes the foundational principles, technical standards, and decision-making frameworks that govern all development choices for a specific repository.

How does this skill help with feature planning?

It provides a 7-phase framework that forces clarification of requirements and technical strategy (via plan.md and tasks.md) before any implementation code is written, reducing technical debt.

What are the prerequisites for using Spec-Kit?

You need Python 3.11+, Git, and the uv package manager. The skill interacts with the specify-cli to manage the .specify/ directory structure.

Can I use this for existing projects?

Yes, you can initialize Spec-Kit in any existing directory using the 'specify init' command through Claude to begin documenting your project's constitution and features.

Productivity & Workflow

Implements a constitution-based, 7-phase specification-driven development workflow using the GitHub Spec-Kit integration.

The Spec-Kit skill transforms Claude into a structured development partner by implementing the GitHub Spec-Kit methodology. It guides developers through a rigorous 7-phase workflow—starting with a project Constitution to establish governing principles, followed by Specification, Clarification, Planning, Task breakdown, Analysis, and finally, Implementation. This skill is ideal for teams and solo 'vibe coders' who want to ensure their technical decisions align with high-level project values while maintaining a clean, version-controlled record of requirements in the .specify/ directory.
