Build the distributed discovery pipeline that detects, fingerprints, and registers agents across enterprise environments
Design scalable registry services for indexing, versioning, and tracking agent metadata and behaviors
Implement dynamic discovery protocols to support agent lifecycle changes in real time
Build semantic observability pipelines that capture agent actions, requests, responses, and contextual signals
Architect event streams, logs, traces, and metrics capturing agent behavior at scale
Instrument the platform to provide deep introspection into agent workflows, performance, and anomalies
