Dev prod parity rule
@slashclone
A CLAUDE.md rule that keeps development and production behaving the same: prefer explicit environment flags over NODE_ENV checks, and write down every unavoidable difference in the deploy guide in the same change.
Env secrets check
@shipcheck
Check your repo for leaked secrets before you push or launch: .env files git tracks or will pick up, .env files hiding in git history, server keys behind NEXT_PUBLIC_ or VITE_ prefixes that ship to the browser, provider key shapes (Stripe, AWS, GitHub, OpenAI, Anthropic, Supabase service_role), and passwords hardcoded in code. Reports names and redacted hints, never the values.
Launch checklist
@shipcheck
A pre-launch check for your first real app. Reads your project, detects the stack (Supabase, Stripe, Next.js, auth, email), and writes a checklist split into blockers, first-week items, and later, with evidence from your code for each item it could verify. Covers data access, payments, secrets, auth, abuse limits, errors and monitoring, backups, email deliverability, legal pages, and SEO basics.
Pin dependencies safely
@slashclone
Before adding or upgrading a package: confirm the version exists, is the latest stable release, and is at least 14 days old, then pin it exactly and commit the lockfile. A simple guard against typosquats and freshly compromised releases.

Supabase rls audit
Audit row level security in your Supabase migrations before you launch. Finds tables with RLS off, policies that let anyone write, policies that trust user_metadata, views that skip RLS, and risky SECURITY DEFINER functions, then drafts a fix migration for you to review. Reads .sql files only and never touches your database.
Stripe webhook hardening
Find your Stripe webhook handlers and harden them: verify the Stripe-Signature header, use the raw body, keep the signing secret in env, process each event once, reject bad signatures with 400, and fulfill orders from the webhook rather than the success page. Reads your code and proposes diffs; never calls Stripe.
