This post has a video example. **TLDR:** Console injection. Anything running in a browser can print a control menu to the console. Claude reads it. Now it knows what it can do, and controls the site without an API. So, no back-end needed. Super simple. Want the full picture? Keep reading. Want your LLM to build this for you? Copy/paste this whole post. --- **THE PROBLEM** You want your LLM to control something in your browser. Your options aren't great: 1. Claude-in-Chrome's built-in tools. It doesn't know what your site does or how to use it. It takes screenshots and guesses. Slow and token-heavy. 2. Build an API server. Now you're managing keys, hosting, and paying per call. **THE SOLUTION: CONSOLE INJECTION** There's a third option. Whatever you're building loads in the browser. On load, it prints a list of controls the AI can use. The LLM reads the console, sees the control list, and runs JavaScript to call those controls directly. It's just a simple JavaScript control list sitting in the console. You can even add a workflow so the AI has an idea of what it can do with those controls. This works for anything that runs in a browser. A SaaS tool, an internal dashboard, a local dev environment, a canvas editor, a data pipeline UI - if it renders in a browser tab, you can give an LLM a control panel for it. Here's what it looks like in one of my tools (hit F12 to see your own console): ``` [AI-ACCESSIBLE] This app can be controlled via JavaScript. * Sidekick.help() - Complete tools reference (returns JS object) * Sidekick.teach() - Full teaching guide, 14 sections logged to console * Sidekick.tool(name, input) - Execute any tool directly * Sidekick.batchAutomap(mappings) - Smart batch mapping (recommended) help() + teach() contain everything needed. No need to fetch external files. ``` The LLM sees that, and it's immediately trained. It can read state, click buttons, type things, batch operations - whatever you've exposed. **IT GETS BETTER**

Check it out here: https://3toedsoftware.com/demos/scylla-01/ 146 commits to get to this point Just showing what we can make with Claude Code. I have almost no coding experience. It's clunky and interesting. Built this with Claude Code + Babylon.js. I like this combo for fast prototyping. It's a 3D deep ocean scene. Very small sandbox. Not a full game yet, more of an interactive prototype. You pilot a submarine around a deep ocean environment. There's a control panel for lights, a mining laser, speed boost, and an inventory system for collecting materials. Also a control panel to mess with lighting and other things in the environment. - W/A/S/D (or arrow keys) — move the submarine - Shift — cycle speed modes (normal, boost, super boost) - L (tap) — toggle/cycle lights - L (hold) — toggle light direction - Left mouse (tap or hold) — fire red laser (mining laser) - Right mouse (hold) — hold on object to lock on and move the mouse where you want to move the thing. it's sloooooow - Middle mouse wheel — increase/decrease submarine depth - Middle mouse click — attach tether (doesn't do anything but look weird right now) - Numpad +/- — zoom in/out Use the green laser to interact. I made it weak for now, so it can only move little things. It will be upgradeable. Use the red laser to burn shit. If you hold the red laser button on the big brown cube the animation will change and you can cut pieces off. If the pieces are small enough, use the green laser to move the cut piece onto the platform to collect it. Super excited to see what you guys make. Any games yet? I did a quick search for "Game" and couldn't find one. Also, just saw that basically every major engine has MCP integration now. I wish I could split into several people so I could make games and also productive apps. I feel like I have to choose one and focus. Or just have my sleep removed and inject demon blood into my body to stay moving.

I edited this post to be an expanded version. If you read the original, this covers the same ground but goes deeper into the why behind each step. This might be useful to you if you're curious how someone actually builds things with Claude Code day to day. Not theory. Not a prompt library. Just the process. This walkthrough uses vanilla HTML, CSS, JavaScript, and .MD files. You'll need Claude Code installed already. The provided Claude.md is specifically tuned for making vanilla HTML, CSS, JavaScript things. --- ## Let's Set the Mood This feels more like sculpting with a friend than prompt engineering. Very organic. I have Claude create a basic idea. A lump of clay. Not pretty. Then we build from there. I imagine what I want and ask Claude to make updates. It updates the file. I test it. I ask for more updates. We keep doing this until we make something we like. We take very small steps. I want to feel each change in UX. This is important. If you try to describe the whole finished product upfront, Claude will give you something that looks complete but feels hollow. Buttons that technically work but don't feel right. Layouts that check boxes but don't flow. You end up spending more time explaining what's wrong with the output than it would've taken to just build it in small pieces. Small steps let you steer. You feel each change. You catch problems when they're small. And you discover ideas you never would have thought of sitting in front of a blank spec. --- ## What We're Building As an example, let's make something extremely useful. We will call it "Useless Spinner App." It will help me make important life decisions. Here's the finished product: https://3toedsoftware.com/demos/useless-spinner/ I picked this because it's small, visual, and instantly testable. You click things. They spin. You see if it works. If something's wrong, you'll know in two seconds. --- ## Setup Two things. **1. Create a folder on your desktop.** Call it "Useless Spinner App" (or whatever you're building).

I'm curious what everyone here likes to do for fun (of course building stuff with Claude is fun too lol), and if you've applied any AI to your hobby. For me it's been super useful for DND planning and I find I get to stay in creative flow more. Curious what other people are doing
