Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes the sole parameter 'docId' as 'Document ID' with 100% coverage. The description does not add any additional meaning about the parameter, its format, or its relationship to the tool (e.g., whether the document must be open). Given the schema coverage is complete, the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
