Every deployment can have one durable agent thread. It keeps the diagnosis, follow-up messages, and proposed actions so a reload or teammate does not lose the investigation. From a deployment in the dashboard, open **Diagnose**, ask a question, and watch status and text events stream in. The same contract is available through the [Deployment Agent API](/api-reference/deploymentAgent). Read-only tools may run while the agent answers. A mutation—such as redeploying or changing a configuration value—is stored as a pending action and cannot execute in the message call. Review the exact target and arguments, then approve or reject it separately. Approval is audited and rechecks authorization at execution time. The older one-shot diagnosis endpoint remains useful for CI: ```bash theme={null} korve deploys diagnose --json ``` Use the conversation for iterative investigation and controlled action; use one-shot diagnosis when you only need a structured cause and suggested fix.
