I built a desktop AI agent that writes its own tools — behind verification gates

A desktop AI agent that writes its own tools — and why every line passes a gate before it runs.

The itch

Agent capability is quietly becoming synonymous with a specific vendor's pricing plan. I wanted the opposite: an agent that runs on my machine, where models are swappable parts (Anthropic / OpenAI / Moonshot, or free-tier OpenAI-compatible APIs), and where the tools it writes stay on my PC as my assets.

So I built AMA-teras (AGPL, Electron + TypeScript): a desktop agent that, when it hits a capability it lacks, writes a new tool plugin for itself.
