Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description must compensate. It does, explaining all five parameters: user_id, fund_name, router_preset with allowed values, aggression_mode with allowed values, and philosophy with a max length. This is exactly the kind of semantic enrichment the schema lacks.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
