Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'id' is described in the schema as 'ID of the resource', and the tool description adds that the action is on an access request, implying 'id' refers to that request. This adds minimal value beyond the schema, but since schema coverage is 100%, a baseline of 3 is appropriate. The description does not clarify the ID format or any constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
