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

thought for 0s · click to collapse

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.

○ glob ROADMAP*

└ ✓ 1 file · ~2 tok

○ read_file ROADMAP.md

└ ✓ 1 line · ~54 tok

▸ thought for 2s · click to expand

● 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

AI assistant

Your own assistant living in your terminal. It has a memory system and access to basic tools like web search. You can ask gatto to write code, do research, update your Windows drivers, or simply have a chat.

100% yours

gatto is GPL-3.0, so you can modify it as much as you want. Local AI models sit on your hard drive and run from 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 an engine (llama.cpp) and helps you pick a model your PC can actually handle. You can add more models and engines later.

Changes hats

A role is a seat: a small file that names a model and a prompt. Useful when coordinating multiple agents, each using a different model for a specific task.

Custom toolset

Ask gatto to write a new tool for itself, then drop it into gatto's extensions folder and voilà, gatto has a new tool. Browse the extension repository. Third-party repositories: coming soon.

Benchmark models

Small AI models are uneven. gatto will put yours through a longer battery of real tasks and show you where it slips up, measured, not judged. 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.
