Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and each parameter has a clear description (colony, username, template_id, and deprecated colony_name). The tool description doesn't add further parameter-level detail beyond what the schema already provides, so it meets the baseline but doesn't exceed it. The description does emphasize the two required parameters implicitly by naming them in the action, but that's minimal.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
