Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline would be 3, but the description adds a real validity constraint on `to` (the name on a connection key that has connected to this workspace) beyond the schema's looser wording. `scope` and `request` are left to the schema, which documents them adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
