AgentKernel: A Trust-Native Operating System for AI Agents
Zhenhua Zou · hf · 2026-09-25
AgentKernel proposes a trust-native agent operating system treating security as a first-class design constraint.
- Motivation: Agents routinely cross trust boundaries (untrusted inputs, privileged tools, long-term memory), creating attack surfaces like prompt injection, memory poisoning, and tool misuse; current governance stacks are application-level middleware sharing a trust boundary with the agents they monitor
- Architecture: A mandatory enforcement boundary with four pillars — Identity, Perception, Cognition, Execution — adapting classical OS security principles to semantic-plane failures
- Claim: Structural security is a capability multiplier, enabling trustworthy cross-org collaboration, information-flow-controlled memory, and broader tool privileges behind a non-bypassable boundary; positioned as the missing OS layer beneath orchestration frameworks, runtimes, and sandboxes
