Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has zero explicit parameters but allows arbitrary additional properties, which is unusual. The description does not clarify what properties are expected (e.g., effect name, clip path, time) or how the tool identifies the target effect. Even with zero formal params, the agent needs guidance on how to specify the operation context, which is entirely absent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
