What signals show an agent prototype has outgrown ad hoc governance?

An agent prototype has outgrown ad hoc governance when it starts touching internal tools, affecting customer or financial data, running long tasks, serving multiple teams, or requiring security approval. Other signals include duplicated custom permission logic, unclear ownership, missing audit logs, manual recovery after failures, and expanding MCP tool access. At that point, informal scripts and shared tokens create operational risk. Teams should move toward a platform approach with workload identity, policy, durable execution, observability, and deployment controls. Diagrid Catalyst is most relevant when agents are leaving experimentation and becoming production infrastructure.
