Can my AI agent figure out exactly which pod/node failed in an active workflow execution?

Yes. If a workflow fails, you can ask your agent to retrieve the workflow tree by name. The agent uses the `get_workflow` tool to inspect the deeply nested structure, traverse the active nodes, and pinpoint the exact step or container that resulted in an error state without you ever needing to click through the Argo UI.

Can I list only scheduled periodic jobs across my cluster?

Absolutely. You can use the dedicated `list_cron_workflows` capability to isolate and return strictly workloads orchestrated on a time schedule across any namespace, saving you from parsing through thousands of isolated runs.

Do I need to expose my internal Kubernetes API to use this?

No. The integration strictly interfaces with the Argo Server UI/API layer via standard REST traffic using a scoped ServiceAccount Bearer token. Your cluster's overarching master `kube-apiserver` remains safely isolated from external agentic logic.
