Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is only 50% (agent has a description, id has only format/pattern). The description adds no parameter information, leaving the id parameter's purpose implicit. For a destructive tool, this is insufficient; it should clarify that id refers to the article to delete.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
