$
A toolkit for Spec-Driven Development, where specifications become executable artifacts that generate the implementation rather than just guiding it. After specify init, you drive an AI agent through staged slash commands like /speckit.constitution, /speckit.specify, /speckit.plan, /speckit.tasks, and /speckit.implement. It supports 30+ agents including Claude Code, Copilot, Cursor, and Gemini CLI, and suits greenfield builds, parallel exploration, and brownfield enhancement.
