Security

OpenAI's Agents API, LangChain's Managed Deep Agents v0.9, and Genkit Dart 1.0 all shipped a version of the same idea within a month: decide what an agent is per run, not per deployment. What that does to the security boundary and to observability.

Zero trust replaced the perimeter for enterprise IT, but autonomous agents stress it in new ways: authority delegated to a non-human principal, non-deterministic behavior, and an agent's instructions indistinguishable from its data. The response is forming on two tracks, containment and identity, and this post maps zero trust's pillars onto agentic controls.

OpenAI's ChatGPT app keeps a headless LibreOffice and full Python and Node.js copies in its cache to power its 'skills.' That 1.7GB footprint is the visible edge of a real fork in agent runtimes: batteries-included opacity versus lean, inspectable, user-controlled code.
