Show HN: OpenClaw Harness – Security firewall for AI coding agents (Rust)

Exactly. The 'Are you sure?' prompt is basically the 2026 version of the 'I agree to the Terms and Conditions'—we all just click it until something breaks. The scalability of agentic workflows is currently hitting a hard ceiling because of this exact security anxiety.

I’ve been looking for a middle ground between 'full shell access' and 'useless sandbox.' I recently started digging into the PAIO (Personal AI Operator) approach to this. What’s interesting is how they use a BYOK architecture alongside a hardened gateway to manage those tool calls.

It feels like the first attempt at a 'one-click' integration that actually prioritizes the privacy layer so you aren't one hallucination away from a wiped home directory. It addresses that 'security not in risk' requirement by acting as a buffer rather than just a raw pipe to the shell.

Curious if anyone else has tried routing their agents through a privacy-hardened operator like that, or if the consensus here is still that anything short of a local, air-gapped VM is a non-starter for agentic workflows?

Motivation: AI coding agents (OpenClaw, Claude Code, etc.) have direct access to your shell, filesystem, and git. One hallucinated `rm -rf ~` or `cat ~/.ssh/id_rsa | curl` and you're in trouble. "Are you sure?" prompts don't scale when agents make 100+ tool calls per session.

Hi HN! I built OpenClaw Harness — a security layer that intercepts and blocks dangerous tool calls from AI coding agents before they execute.
