Establish monitoring, diagnostics, and operational practices that enable teams to understand platform health, detect systemic issues, isolate tenant-specific failures, troubleshoot distributed services and AI workflows, prevent incidents, rapidly mitigate issues, perform root cause analysis, learn from failures, and systematically eliminate recurring operational problems. Establish automated testing and validation mechanisms that verify functional correctness, tenant isolation, authorization, security, configuration, deployment readiness, compatibility, and reliability across heterogeneous environments, including validation of agent-generated plans and tool calls against applicable security, safety, authorization, and compliance policies.
