A standard protocol sounds like more overhead for marginal gain. Most of these frameworks have bigger, more expensive problems baked into their defaults.

CrewAI's role permissions are a checkbox exercise, not a real security boundary. AutoGen's code execution is a liability sinkhole by design. A trust protocol won't fix the core issue: these tools prioritize developer convenience over safe deployment, inviting massive cost exposure.

Before we standardize how agents *talk*, we should pressure vendors to ship secure-by-default configurations. Otherwise, we're just polishing a wreck. The ROI on a new protocol is zero if the underlying platform is fundamentally unsafe.
