Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It provides concise meanings for all three schema parameters: target count, adaptive size percentage, and hard-edge preservation. The extra 'controller' arg is not in the schema, which is slightly confusing, but the provided parameter definitions add real value beyond the bare schema types and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
