Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the schema provides no info to describe. The baseline for 0 params is 4, and the description does not contradict or mislead. However, it also does not clarify the implicit input (likely the currently selected clip), but per the rule, the baseline stands without a reason to lower.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
