The problem
People building with AI tools ship what the tool writes, and the tools skip the same things: row-level security, where keys live, auth redirects, server-side checks. Nothing in the demo shows it.
The fixes are well known to anyone who has shipped a production app. They just aren’t written anywhere the AI tool reads.
What I had to learn
- How each tool takes instructions: CLAUDE.md and skills for Claude Code, .mdc rules that load automatically in Cursor, project-knowledge files and step-by-step prompts for Lovable and Bolt.
- How to write a rule a model follows rather than acknowledges: specific, testable, with the check that proves it was done.
- Selling and delivering digital files: Stripe Checkout, a webhook, signed download links and release versioning.
What I built
Project rules for Claude Code, Cursor, Lovable and Bolt covering security, Supabase RLS, auth, environment variables, deployment, database changes, errors, performance, SEO and UI quality.
Seven Claude Code skills: RLS audit, pre-deploy check, auth flow fix, AI visibility, safe change, plan feature and slop check. Drop-in templates for Vite + React and Next.js, plus checklists and SQL.
- 01
Every rule ships with its check
The RLS audit skill does not stop at writing policies. It tests as a logged-out visitor and as a second user, because a policy that looks right and leaks is the common case.
- 02
The same rules in four formats
One set of rules, adapted to how each tool loads instructions. Someone who switches from Lovable to Cursor keeps the same guardrails.

Free, and no email
It was sold as five packs, then made a free download with no sign-up. The people most likely to use it are founders building with AI tools, the same people who might need a rescue later; a paywall kept them out.
| TEST | BEFORE | AFTER |
|---|---|---|
| Logged-out visitor reads tasks | 3 rows | 0 rows |
| Logged-out visitor deletes Ben’s project | deleted | permission denied |
| Ben makes himself admin | admin | permission denied |
| Ben uploads into Asha’s folder | allowed | blocked by row-level security |
| Asha renames her own project | 1 row changed | 1 row changed |
Where it stands
A free download at anadithakur.in/products/production-kit, versioned, with no account.
What it taught me
Writing rules for a model is writing for a reader who does exactly what the words say, so every rule ends in a check that shows whether it was followed.
Paid packs and checkout were built before anyone had asked to pay. In September 2026 the kit went free.
One download, no sign-up.
