❯ Hi, can you check the ROADMAP file and tell me what we should work on next?

I need to find the 'ROADMAP' file in the current directory or subdirectories, read its contents, and then

suggest the next task based on what's written there.

● The ROADMAP.md says the next step is to build a JavaScript prototype with simple graphics to

nail down the mechanics for "Plappy Bird."

To get that started, we need to define the core loop. Should I start by asking you some questions about

the mechanics (like gravity, input, and obstacles), or do you already have a specific design in mind?

What gatto does

100% yours

When you use a local AI model, it sits on your hard drive and runs on your own hardware. What you type and the files you open never get sent anywhere — full privacy, by design.

Sets itself up

On the first run, gatto downloads what it needs and helps you pick a model your PC can actually handle. You can always add more models later.

Changes hats

gatto has a role system that steers smaller models to behave in specific ways — a general assistant, a coder, and an oracle for thinking problems through.

Takes new tools

Ask gatto to write an extension for itself, drop it into gatto's own folder, and it gains a new tool. Browse the official extension repository for more. Adding third-party repositories: coming soon.

Benchmarks models

Small AI models are uneven. gatto will test yours, find where it slips up, and adjust its own instructions through the role system to make up the difference. Coming soon.

A note on the first launch: gatto is not code-signed, so Windows shows “Windows protected your PC” the first time you run it. Choose More info → Run anyway. A signing certificate costs money gatto does not have; the warning is about the absence of a receipt, not about the file.
