Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents the single optional task_id parameter. The description restates the same meaning (provide task_id to restore one, omit to restore all) without adding syntax, format, or edge-case details beyond the schema, matching the baseline for high coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
