How to publish a page on Cloudflare Workers We get to know Cloudflare Workers and build a skill that publishes a folder with a static page and updates it at the same address. Inside: setting up the account, a ready-made task for the agent, and checking the result.

Static sites, frontend, and backend Two sites look equally finished, but one ships by copying a folder, while the other needs a server running a program, a database, and secrets. Here is what a static site is, how frontend differs from backend, where data lives, and why that decides the way you publish. Plus a table of hosting options for static files and for programs, and what to ask the agent before it offers to "spin up a server".

A screenshot as a brief for the agent You have a picture, and "make it look like this" already works: the agent gets the whole screenshot and matches your page to it. A short guide: how to hand the image over, what the agent reads from it reliably, what the picture cannot tell it, and what to add in words so you get what you need instead of something that merely looks similar.

How to pick a plugin and install it safely A plugin is not "a bigger skill", it is a stamped crate that, besides abilities, can hold programs, automatic reactions and cables out to external services, and all of it runs with your permissions. Let's look at what is inside, where marketplaces come from and how the three sources differ, what Claude Code shows you before you install, who gets the plugin and what it costs in context. How to install it, try it on your own task, disable it and remove it, and why the same questions are worth asking about any downloaded skill.

From a file on your computer to a public link The page opens in your browser, and nobody else has it. Let's walk through the route that turns a file into a link: the server, the domain and the IP, the path and the default file, hosting and deploy. What exactly travels to a host, why one link lives for an hour and another one sticks around, where an access key belongs, and what the agent does when you ask it to "publish this".

A brief for the agent: how to turn an idea into a task The agent builds exactly what is written down and fills the gaps in your request on its own. We take "I want a game" or "make a nice page" and turn it into a brief of six to eight lines: the goal, what should happen, what the first version will not have, and how we will check. Plus what to do with the agent's questions and assumptions, when to build a sandbox, and why the brief lives in a file rather than in the chat.

How a Large Language Model Works Behind every response is a mechanism that does exactly one thing: estimate which continuation is most likely. We will look at how a model measures text, why a response appears piece by piece in the terminal, where the model's knowledge comes from, and what Thinking on the screen actually means.

HTML, CSS, and JavaScript: what a web page is made of The agent edits the files in a web project, but you are left wondering what lives where. Using a simple example, this article explains three core technologies: what tags and attributes are, how CSS rules work, what JavaScript does, and how one element connects markup, styling, and logic.

Why AI gets things wrong so confidently The agent confidently explained how your project is put together, except there is nothing of the sort in it, and this was said in the same calm tone as everything correct before it. We look at what the model actually sees in your request, why confidence in an answer proves nothing, and which three checks catch most of these misses.

Skills: how to hand your agent a ready-made ability A skill is a folder with instructions that Claude Code pulls in when the task fits, or when you call it by name. Where that folder lives, how to check a ready-made skill, why the description matters so much, and how to build your own without doing it all by hand.

Rollback in Claude Code: what a checkpoint is and what it will not bring back Claude Code snapshots your code before every message you send, so edits made through its file-editing tools can be wound straight back. How that menu works, where the rollback stops, how long it lasts, and how it differs from a copied folder and from real version history.
