Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% for three parameters (pageId, start, limit), so the description must compensate. It only hints at paging with "one page" and never clarifies that pageId is the Confluence page whose labels are listed, nor how start/limit behave together (defaults 0/25, max 100).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
