Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 0%, so the description must compensate. It does mention that the 'symbol' parameter is an optional filter, but it does not clarify what constitutes a valid symbol (e.g., crypto ticker, fiat code, case sensitivity) or any default behavior. This leaves significant ambiguity for the agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
