Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description carries the full burden and does substantial work: it names the source of draft (quote.draft), the quoteToken, originalUnitAmountCents ('用户所选原价(分)'), and the coupled trio preview/previewHash/consent with the exact values expected on the confirming call. It also maps the nested draft fields to human concepts (全文/标准/期限/观察期/人数/五项金额). Two top-level params, images and needId, are never mentioned, and the derivation of previewHash is left implicit.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
