Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so every parameter is already documented, including the preference for articleTitle over articleId and the optional narrowing role of workspaceId/workspaceName. The description restates that preference in prose but adds no syntax, format, or ambiguity-resolution detail beyond the schema, so baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
