Spec Driven Development for Developers and AI Agents.
Turn endless iterations into one-shot features.
Shotgun writes codebase-aware specs for AI coding agents. We index your entire repo, research how features should fit your architecture, and generate technical specs that keep Cursor, Claude Code, and Lovable on track.
Export to AGENTS.md. Your AI agent builds correctly the first time instead of derailing halfway through.
Open source CLI for developers working with AI coding agents.
