Outshift by Cisco said its new open-source stack—AGNTCY, Mycelium and CASA—aims to let AI agents share intent, context and reasoning so they can coordinate decisions without human stitching.
Mycelium is the semantic coordination layer: in internal tests across 14 scenarios, structured agent groups reached decisions 93% of the time versus about one-third for unstructured groups.
AGNTCY provides the underlying connectivity layer for agent discovery, identity and messaging across systems and companies, extending a Linux Foundation project that already includes more than 75 participants.
CASA adds continuous task-level authorization to curb risks such as prompt injection, memory poisoning and over-privileged agents; Outshift said agents today cannot confirm they are cleared for a job roughly 90% of the time.
The push reflects a broader shift from scaling single models vertically to scaling intelligence horizontally across enterprises, where current open-source multi-agent systems still show failure rates of 41% to 87%.
