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

Does Harden work smoothly with different coding agents, or is it mainly optimized for tools like Claude Code right now?
Harden
@maali_baali Hi Maali, Right now, we support 7 AI coding agents, including:
Claude Code
Cursor
Kiro
Codex
Hermes
OpenCLaw
Anti Gravity
This is such an interesting problem to solve. We’re giving agents more autonomy every month, so the security layer has to catch up too
Harden
@prakhar_gupta44 Yeah, exactly. As agents get more dominance, the security has to speed up, but now Harden has got your back, and it is free for individual developers. You can just set it up in a single command. If you hit any issue while setting up, just book a call with us. Our team would be more than happy to help you out
The “nervous parent” analogy is painfully accurate. Giving coding agents more autonomy without giving up control feels like the missing piece.

@ramana_abhishek Hi Ramana, glad that analogy felt relatable, and that is exactly the feeling we are trying to solve for with Harden.
Paste
"Babysitting caps how much work you can hand off" is such a clean way to put it. I also like that it all stays local — a tool that reads every command is exactly the thing you don't want phoning home. Does the model learn anything from what you approve or reject over time?
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 :)
