Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With annotations covering read-only, idempotent, and non-destructive behavior, and an output schema presumably covering fields, the description still communicates the key result concept (Seemor IDs) and the coverage_level variants. Nothing an agent needs to use this tool correctly is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
