Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 100% schema coverage, the baseline is 3, and the description adds value beyond the schema by connecting capability to search behavior, task_input to execution, and USDC to the on-chain funding step. The schema-level note that only capability, task, and price ceiling are used further reinforces parameter meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
