Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning beyond the schema by linking parameters to specific modes (e.g., thing_one/thing_two for connect, event for investigate, prompt for complete). This clarifies conditional parameter usage, which the schema alone does not express. Schema description coverage is 57%, and the description compensates by explaining which parameters are relevant for each mode.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
