What DiagnoseAHORunFailure does on AWS IoT SiteWise MCP Server

AI agents call DiagnoseAHORunFailure as a supporting operation in AWS IoT SiteWise MCP Server workflows.

WHY IT NEEDS A POLICY

Why DiagnoseAHORunFailure needs a policy

The name suggests a diagnostic/read operation (analyzing failure information), but the description is empty so the actual behavior is unknown. 'Diagnose' typically implies reading/querying failure data, which would be a Read category. However, without any description, confidence is low. Defaulting to Read-like behavior based on naming convention, but categorizing as Other due to insufficient information.

From the tool's definition Tool name 'DiagnoseAHORunFailure' and empty description provide no detail about what the tool does beyond suggesting it diagnoses a run failure.
