If you're deploying ADK agents and need to understand what they're doing in production, this gets you set up with Google Cloud's observability stack. Cloud Trace works immediately, but prompt-response logging and BigQuery analytics need Terraform infrastructure provisioned first, and the order matters: run infra before your first deploy or you'll create state conflicts. The skill walks through three tiers (tracing, logging, analytics) plus third-party integrations like AgentOps and Phoenix. Most useful when you're past the prototype phase and need to debug latency, audit LLM calls, or build custom dashboards. The Terraform sequencing gotcha is the kind of thing you want to know before you deploy, not after.
