Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description fully compensates by documenting every parameter: issue_id, page_num, page_size, project, work_item_type, and user_key. It adds meaningful semantics like defaults, the server-side page_size limit, the FEISHU_PROJECT_KEY fallback, and what 'project' can be.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
