Harden

A security layer for AI coding agents

Harden AIF is a free, local security tool for AI coding agents. Its post-trained model checks tool calls before they run, using your request and session context. It outperformed frontier models on key agent-security benchmarks, and because it runs on your machine, your repo and tool output stay on your computer.
