Built for Agent-First Game Design

Open GDD is a public, chaptered GDD template designed for AI agents and human teams. It helps you turn a game idea into a real GDD with clear constraints, reviewable diffs, and reusable structure.

After watching too many AI-assisted projects drift, we built a simple upstream discipline: write decisions as chapters, cite them in prompts, and review every change like code.

This template is maintained by a small, hands-on team. Every improvement starts from real production constraints: what teams can actually review, adopt, and keep consistent over time.
