Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is only 17%, so the description must compensate; it does add real meaning for the highlighted parameter (include="valuation" toggles currentPrices 0-1 and markValue) and clarifies the units of totalSpent/totalReceived/cost basis. It still leaves limit, cursor, chainId and marketAddress semantically undocumented, keeping it short of a 5.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
