Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 67% (2 of 3 params have descriptions: name has none, position has context about 0-indexing, checklist_id is self-explanatory). The description adds value by clarifying that name relates to renaming and position to reordering, which aligns with the schema. However, it doesn't clarify whether name is optional and independent from position, or whether providing both is expected. Baseline 3 is appropriate given moderate schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
