Spec Kit

Open-source scaffold from GitHub that operationalizes spec-driven development with AI coding agents. Creates structured .specify/ folders that serve as the source of truth for Claude Code, GitHub Copilot, and Gemini CLI — steering AI generation from upfront specs rather than improvised prompts.

GitHub Copilot

Inline code completions and chat across IDEs. Deeply integrated with GitHub and VS Code. Used by millions of developers.
