Agent-Zero is a GitHub template that you can use for new coding projects that use AI-first development workflows. It includes the minimum necessary to nudge agents to write good code, work well in sandboxes, and get stuff done on GitHub (e.g. commits and PRs). It only includes a basic CLAUDE.md file and a few scripts and GitHub templates so it's very easy to customize. I've had good luck using it to produce high-quality coding output but that's subjective so your mileage may vary (e.g. https://github.com/kstackhq/kstack). If you have any suggestions on how to improve the template let me know!
