Can I see the status of all nodes in a cluster through the agent?

Yes! Use the `list_cluster_nodes` tool with the unique cluster ID. The agent will return a list of all nodes, their IP addresses, and their current health/operational state.

How do I check for recent scaling or upgrade events on my database?

Use the `list_cluster_operations` tool. Your agent will fetch the management log for the cluster, showing you recent tasks, their progress, and whether they were successful.

Where do I find my CockroachDB Cloud API Secret Key?

Log in to the CockroachDB Cloud Console, navigate to **Access Management**, and select **API Keys**. You can generate and copy a new Secret Key from that section.
