FAF provides a standardized mechanism for sharing project architecture, conventions, dependencies, and goals across heterogeneous AI agents, addressing context fragmentation in multi-agent development environments. FAF is registered with IANA as "application/vnd.faf+yaml" (October 2025). This document seeks registration as "application/faf+yaml".
