Why this exists

You already ship with agents. The question is which level you ship at.

Three tools, three release cadences, and no way to tell whether the setup you copied last quarter still matches the version you run today. This is the documentation for the part the vendor docs skip — written by one person who builds with agents daily: 26 years on the web, two IPOs, CTO at TasteRay, AI lecturer at SWPS University.

Shipping web apps

26 years of building for the web — two IPOs along the way.

2023

Cursor, day one

Prototypes came easy. Production — reviews, edge cases, scale — didn’t. Official docs covered features; YouTube covered demos.

2025

CTO at TasteRay

Building the whole product with agents — and writing down every pattern that survived a review.

AI Developer Toolkit

Those notes became 400+ articles and 100+ recipes, each carrying the date it was last updated.

What You Can Check Before You Pay

  • The ladder is the map: Levels 0 to 5, after Dan Shapiro. The three scorecards place you on 1 to 4 and name the rung above — free, no account
  • A date on every guide: Every guide shows the date it was last updated, so you can see whether it predates the release you run
  • Written by someone who ships: The patterns come out of a product in production, not a toy example
  • Honest about trade-offs: It says where an agent is the wrong tool, and where a human still has to look
