Shotgun - AI Cofounder Framework

An open-source operating system that turns your favorite AI agent into a persistent, personalized virtual cofounder for solo founders. It works on any AI agent, with first-class wiring for Claude Code, Cursor, Antigravity, Gemini CLI, and GitHub Copilot. One line installs it, shotgun-init injects the full OS into any folder or existing codebase, you run onboarding once, and from then on the agent knows your venture, remembers everything, builds your product, and keeps your data organized.
