​
Error reference

Errors are surfaced by the CLI, provider adapters, tool dispatchers, and policy gates. The exact message and exit behavior depend on the failing layer.

​
Use the current implementation

Capture the command, package version from nova --version, relevant non-secret diagnostics, and the first error. Retry only when the error is transient; otherwise inspect authentication, configuration, permissions, and tool availability in that order.

​
Boundaries and safety

Never paste API keys, cookies, tokens, or full private prompts into issue reports. A successful retry does not establish that the original operation was safe or complete.
