Spec-Driven-Development
A Claude skill that interviews you before any code is written and generates a shared requirements, design and task plan, then creates matching configuration files so Claude, Cursor and Copilot stop contradicting each other.
This skill addresses AI coding tools working from no shared source of truth, each filling gaps in an ambiguous request with its own assumptions. Before any code is written, it interviews the developer and generates three files: requirements.md with traceable, testable requirements, design.md describing how the system will be built, and tasks.md listing what to build next in order, each task linked back to its requirement.
It then creates matching configuration files for Claude Code, Cursor, Copilot, Windsurf and Aider, so every tool reads from the same plan. Starting a conversation with a prompt such as wanting to begin a new project, or already having a codebase with no specs yet, walks through a short set of questions and produces the spec files without further configuration.
It installs as a Claude skill file or a Claude Code plugin, and is written in Python under the MIT license.
