Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With schema coverage at 0%, the description compensates well by defining tc_id as 'Timecode show ID' and listing valid actions with their meanings (e.g., 'go' means play). Examples further clarify usage, adding significant value beyond the raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
