You know the feeling when you walk into a new pizzeria? A wall of pizza names, fifty of them, and no way to get a grasp of what they all contain. I just want to know which ones have the melted cheese situation I am after, and picking from a long list of names feels overwhelming every time.

So I built pizza-menus. Paste a pizza place’s website, and out comes a brand-new menu for it, a self-contained page where one can filter the pizzas by ingredient. Click the toppings you care about and the list shrinks to the pizzas that matter.

But this post is really about two things, because the pizza service is built on top of another project, a workflow builder running on the lab in the closet. You define agent workflows in the browser: inputs, an action prompt, an eval prompt, and tools (the borrowed browser, for one). Each run gets its own sandbox folder, and a worker at home picks jobs off the queue and runs them with the Agent SDK. The hard part with a project like that is finding something real to test it with, and here I actually had a problem of my own to point it at.

The part that made me smile is the chaining. The eval prompt is not just a summarizer, it can call next_workflow("Some workflow", "handover note", inputs) and pass the whole sandbox on to another workflow, which continues right where the first one stopped. So a workflow is really more of a node, and maybe “workflow nodes” is the better name. I have not renamed anything yet.

And how do the two talk? A workflow can get a named endpoint with its own bearer token, so the whole integration is one curl:

curl -X POST https://rpi6.memention.net/workflow/api/endpoints/new-menu \
  -H "Authorization: Bearer <token>" \
  -d '{"url": "https://some-pizzeria.example"}'

pizza-menus is just a small queue in front of that, one job at a time, poll for status, mirror the resulting menu.html and serve it. I fed it hm.com to see what would happen, and the workflow looked at the page, decided this is not a pizzeria, and refused to bake anything. Good kitchen.
