RISK

Why GOOGLESUPER_FREE_BUSY_QUERY is rated Low

This tool queries calendar availability status without creating, modifying, deleting, or executing any operations. It falls squarely within the Read category as a data retrieval function. The severity is low because exposure of free/busy information, while potentially revealing scheduling patterns, does not enable financial transactions, data destruction, or system compromise.

From the tool's definition Tool name includes 'QUERY' and description states it 'Returns free/busy information' — a retrieval operation with no modification, deletion, or execution of external processes. Free/busy data is read-only calendar metadata.
