AI Rules Pack for modern FE Development : Stop teaching AI your code conventions every session

I spent ages correcting the same AI mistakes on every project. Every time I opened Cursor on a new Next.js codebase, the same things happened: useEffect for data fetching, tailwind.config.js, useFormState, middleware.ts, etc. All things that were outdated or I did not want. So I did something about it. I spent several hours writing a complete set of Cursor + Claude Code + OpenAI Codex compatible rules for modern frontend SaaS/Web development — covering Next.js 16, React 19, Tailwind v4, shadcn/ui, and the auth/database/data fetching choices most teams are actually making in 2026. Then I packaged it into a proper product with a CLI installer so the user could choose whatever they prefer and a user manual explaining how it all works. THEN, to centralize it and all future digital products I might develop, I built a brand around it. I'm proud to announce that Saastenance is live today — a digital product store for developers who want tools that match how things get actually built today. First product: the AI Rules Pack. One command, 4 questions, and your AI coding tool knows your stack and knows exactly how you want it to think.
