On: We built a runtime security layer for AI agents (instead of prompt filtering)

[Arikernel]

Most approaches to agent safety rely on prompts.

We built something different: a runtime layer that intercepts tool calls and enforces policy (filesystem, HTTP, shell, etc).

Example: Agent reads a webpage → becomes tainted Then tries to access sensitive files → blocked Then tries exfiltration → quarantined

Curious if others are thinking about agent security this way.
