Launched this week
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 beat frontier models on key agent-security benchmarks, while keeping your repo and tool output on your machine.














Really cool approach to agent security. Love that the checks happen locally while still being powerful enough to catch risky tool calls.

@harsh_rathore10 Thanks, Harsh. Really glad you like the approach and that it resonated with you. Also, really good DP :)
Congrats on the launch! Love that it checks agent actions locally before they actually run.. feels like a no brainer for anyone letting coding agents loose on real repos. Upvoted, excited to see where this goes!!

@vinayak_mishra5 Appreciate that a lot! That’s exactly the use case we had in mind, keeping agents useful without giving them unchecked access to real environments. Thanks for the upvote and support 🙌
This looks really useful for keeping coding agents safe.
Nice to see it works in the background without adding extra work.

@renu_rani Thanks, Renu! AIF stays in the background, checks actions before they run, and keeps the workflow moving without constant interruptions.
