Everyone's talking about AI Agents for Business, but most haven't actually built one, let alone sold it profitably. I've done both multiple times.

Here's the exact playbook I'd follow if starting from zero today - a complete roadmap from learning the basics to landing paying clients. Let me know if you want a YouTube video around it too. 1/ KNOWLEDGE FOUNDATION (Levels 1-2):

First, master the models and their strengths.

- GPT-4o-mini is perfect for low-level intent classification and basic categorization - cheap and fast at around $0.15-0.60 per 1M tokens.
- Gemini excels with large context windows, ideal for long documents.
- Claude is best when output needs to sound human-written: emails, summaries, anything that gets read carefully.

Next, understand automations vs agents. Truth most builders won't admit: You rarely need full agents. 95% of profitable AI tools are automations with smart features. Automations take input, process it, give predictable output. Agents think, adapt, make sequences of decisions - they're complex and expensive.

Default to automation unless you absolutely need the complexity.

Your vibe-coded SaaS is a security breach waiting to happen.

Cursor and Windsurf will happily ship the leak.

Even @InterviewCoder leaked secrets early into launch.

As someone who has built multiple production-ready applications with thousands of users, from just Cursor with minimum interaction:

here’s a simple system to remove 99% of vulnerabilities, with prompts you can paste straight into Cursor/Windsurf👇 1. Secrets:

Most vibe-coded apps leak secrets by hardcoding API keys. Cursor and Windsurf won’t protect you unless you do it right.

- Put public/non-sensitive defaults in .env (e.g. NEXT_PUBLIC_API_URL=...)

- Put secrets and overrides in .env.local (e.g. SUPABASE_KEY=...)

- Add .env.local in your .gitignore file.

Fix it in Cursor/Windsurf:
“Use process.env. for every secret. If the code needs config, tell me the exact key to add to .env.local. Assume .env.local already exists.”

Then deploy secrets in Vercel → Settings → Environment Variables.

Any host (Cloudflare Pages, Railway) works - just keep your keys off GitHub.

I promise you you’re vibe coding wrong

as someone who has built multiple production-ready applications, with thousands of users, from just Cursor with minimum intervention.

But first here's you (probably):

You open Cursor. Type “build me X.”
It spirals. Nothing works. You start over.
That’s not development. That’s chaos.

I have an incredibly simple system that works every single time: Step 1: architecture.md

Open ChatGPT (4o, not o1/o3/o4) and say:

“ I’m building a [description of your product - the more detailed the better]. Use Next.js for frontend, Supabase for DB + auth.
Give me the full architecture:
- File + folder structure
- What each part does
- Where state lives, how services connect
Format this entire document in markdown.”

Save its output as architecture.md and throw it in an empty folder where your project will live.

As promised, here’s the Reddit playbook that got me 1,000 users in 4 days, all without a single ad.

High-conversion post templates included.

This isn’t one-size-fits-all, but it might work for you like it did for me: Fair warning:

This worked for me because of my product (college counseling) and the subreddits I chose.

If you blindly copy/paste this, it probably won’t work.
Steal the principles, not the words. Use your brain.

Also I guarantee this doesn't blow up as hard as the last tweet. No one wants to actually do the work they just want to keep 'learning'. Good luck:
