Prompt-level guardrails (constraining agent behavior solely through system prompts) are inherently fragile, and a more reliable direction is to enforce controls at the tool-call level.

UnverifiedIndirect prompt injection is more dangerous than direct injection because agents often cannot distinguish between content to be processed and instructions to be followed.79% similarUnverifiedSetting clear boundaries for agents, defining explicit task decomposition, and establishing verifiable checkpoints tend to yield more stable results than allowing unconstrained free-form execution.78% similarUnverifiedThe fundamental defense against prompt injection lies in narrowing permissions at the architectural level rather than relying on the model's comprehension, because models cannot reliably distinguish instruction boundaries; what truly prevents unauthorized operations is server-side rejection.77% similarUnverifiedThe Delegated Agent Sessions mechanism fills a permission constraint gap that previously could not be closed at the architectural level.77% similarUnverifiedSecurity isolation for sub-agents should adopt physical isolation (directly removing tools) rather than rule-based isolation (documentation constraints), because large language models carry prompt injection risks that may allow rules to be bypassed.77% similar
