AI-Assisted SaaS Development

killdate-kit is a forkable repository that gives your AI coding tools the structure they need to build production SaaS without drifting. It includes a pre-wired CLAUDE.md, Cursor execution rules, and a runbook system — the scaffolding that turns capable models into reliable engineering partners.
