Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes 'id' and 'data.reason', so the baseline is 3. The description adds 'id=entry', clarifying that the id parameter refers to an entry resource, which is useful. It does not add much about the 'reason' parameter beyond the schema, but the dedup and privacy notes provide some operational context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
