Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It adds meaning by indicating that 'spaceKey + title' are paired together as an alternative to 'pageId'. However, it fails to clarify whether parameters are mutually exclusive, what happens if both are given, or whether spaceKey alone is valid. Some semantics added, but incomplete.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
