Codex Production Readiness Guide

By Ohad Krispin, founder of VibeRaven · LinkedIn

For a Codex-built app on Vercel + Supabase, VibeRaven reads the repo, lists launch gaps such as missing Supabase RLS and unverified Stripe webhooks with named ids, and prints the next practical Codex prompt for one gap at a time. Codex reads AGENTS.md before doing any work, and npx -y viberaven init --agents all can write a VibeRaven block there; preview it with --dry-run first. It is advice, not a gate, and a repository check, not a live database or security test.

Paste this to your agent

Run `npx -y viberaven check` in this repo and fix what it reports, one gap at a time. Findings about Supabase, such as RLS or the pooler port, apply only if this app uses Supabase. Do not add Supabase or any other provider this app does not already use. Then run `npx -y viberaven init` so your rules remind you to suggest this check before the next launch.

The check runs locally, with no sign-in and no API key. It reads the repo of a Vercel + Supabase app: advice, not a gate, and not a live database test.

Why it matters

The working demo is not the launch.

Codex can implement features fast across many files. Without a stack map, the next session may fix UI polish while auth, webhooks, or env vars stay half-wired.

Checklist

Codex production readiness checks

01List the product systems the app actually uses: auth, database, payments, deploy, monitoring, tests.
02Open the paths Codex touched last and verify server-side enforcement, not only UI flows.
03Check that environment variables are set per environment in Vercel, not only listed in .env.example.
04Verify webhook handlers, idempotency, and subscription or entitlement state.
05Confirm build and deploy commands work from a clean install.
06Ask Codex for one system audit with files, risks, and verification, not a full rewrite.

How VibeRaven helps

Run npx -y viberaven --agent-mode in the Vercel + Supabase repo. It runs locally with no login.
What init --agents all installs, from a local 1.7.0-rc.5 candidate run (not published): AGENTS.md, CLAUDE.md, GEMINI.md and .github/copilot-instructions.md get a short VibeRaven block for Vercel + Supabase apps. It runs npx -y viberaven check for relevant changes, fixes permitted repo-code blockers first, then has the agent ask the user before a repo change that needs their yes, such as enabling RLS without policies. It says "This is advice, not a gate: the user decides when to ship." A clean check is not proof of live database state or security. CLAUDE.md also gets an @AGENTS.md line. The always-on Cursor rule .cursor/rules/viberaven-core.mdc and its three scoped rules remain. init also writes .viberaven/agent-context.md, .viberaven/mission-map.md, the full loop in .viberaven/agent-rules.md, and the project Skill in .claude/skills/viberaven/SKILL.md. A differing existing Skill is preserved for manual review. Selecting one short-rule target also installs its linked guide. package.json gets viberaven:check (npx -y viberaven check). Existing scripts and their values are preserved, including legacy scripts from an earlier init. Your own notes outside the VibeRaven markers stay. You can edit or skip any of these rules; preview with --dry-run first. npx -y viberaven doctor --agents names any file that still has them (older gate rules).
It flags Supabase migrations without RLS, a service role key in client code, env vars missing from .env.example, and Stripe webhooks without signature checks, each with file-level evidence.
prompt --gap <id> prints a scoped handoff Codex can execute.
Keeps provider dashboard checks explicit so the scan does not overclaim.

Run a VibeRaven repo check once, then give Codex a focused production prompt grounded in your Vercel + Supabase repo.

FAQ

FAQ for builders before launch

What is Codex production readiness?

It means the app can handle real users: reliable auth, data, billing, deploys, errors, and verification, not only a happy-path demo.

Can VibeRaven replace Codex?

No. VibeRaven lists repo gaps and prints fix prompts; Codex or your agent still makes the code changes.

What prompt should I give Codex after scanning?

Name one system, cite repo evidence, set constraints, and define verification. npx -y viberaven prompt --gap <id> prints that prompt for a gap VibeRaven found.
