Install
Copy this and paste it into Claude Code, Cursor, or any AI assistant:
I want to add the "Spec Kit" prompt rules to my project. Repository: https://github.com/github/spec-kit Please read the repo to find the rules/prompt file, then: 1. Download it to the correct location (.cursorrules, .windsurfrules, .github/prompts/, or project root — based on the file type) 2. If there's an existing rules file, merge the new rules in rather than overwriting 3. Confirm what was added

About Spec Kit and Specify
GitHub Spec Kit is a comprehensive toolkit for implementing Spec-Driven Development (SDD) - a methodology that emphasizes creating clear specifications before implementation. The toolkit includes templates, scripts, and workflows that guide development teams through a structured approach to building software. Specify CLI is the command-line interface that bootstraps projects with the Spec Kit framework. It sets up the necessary directory structures, templates, and AI agent integrations to support the Spec-Driven Development workflow. The toolkit supports multiple AI coding assistants, allowing teams to use their preferred tools while maintaining consistent project structure and development practices.
Supported AI Agents
Spec Kit works natively with: Claude Code, GitHub Copilot, Cursor, Windsurf, Gemini CLI, Qwen Code, opencode, Codex CLI, and 20+ more AI coding assistants.
