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 states 'Name of the item to remove' which matches the schema's declared 'item_name' param, but adds no additional semantics like case sensitivity, whether exact name matching is required, or how the name should be obtained (e.g., from view_cart results). Table stakes only.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
