Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already provides the only parameter with 100% description coverage, so the baseline is 3. The description adds genuinely useful format rules such as lowercase letters, digits, hyphens, underscores, 4–32 characters, and start/end constraints, which go beyond the schema phrase 'the new team address'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
