用工作对象、输出结果和采购场景，理解两类合同智能产品的边界。Understand the difference through inputs, outputs and procurement scenarios.
先看你要解决哪类问题Start with the problem
如果你需要判断一份合同有哪些条款需要关注，先看合同审查；如果你需要知道两个版本改了什么，先看合同比对。两者服务于不同的问题，也可以围绕同一合同工作流程组合。If you need to identify points that need attention in one agreement, start with review. If you need to know what changed between two versions, start with comparison. Both may serve the same overall workflow.
选型时先列出业务角色、合同类型、实际工作步骤和输出使用者。产品名称不能替代场景验证，代表性样本比抽象功能清单更能帮助判断。List business roles, contract types, actual steps and output users first. Product names do not replace validation; representative samples are more useful than abstract feature lists.
审查关注问题，比对关注变化Review finds concerns; comparison finds changes
合同审查围绕合同文本、审阅立场和企业规则组织关注点。使用者需要核对提示所依据的原文与上下文，并对建议作出最终判断。Review organizes points against the contract text, review perspective and company rules. Reviewers check the source and context, and make the final decision.
合同比对围绕两个版本的新增、删除和修改组织核对。差异本身不等同于风险；付款期限变化、责任调整等内容仍需由业务和专业人员结合实际背景确认。Comparison organizes additions, deletions and changes between versions. A difference is not inherently a risk; payment or responsibility changes need contextual review.
用同一批样本完成验证Validate with representative samples
建议准备经授权、脱敏的合同样本，覆盖常见类型、表格、编号、修订和异常文件。提前定义正确结果、漏检与误报的判断方式，并记录人工复核所需时间。Prepare authorized, de-identified samples covering common types, tables, numbering, revisions and problem files. Define expected results, misses and false positives, and record human review time.
格式支持、扫描件识别、长文处理、导出、权限和审批对接应分别核验。不要把某个测试样本的效果直接推广为所有文件的能力。Verify formats, scans, long documents, export, permissions and approval integration separately. A successful demonstration does not establish coverage for all documents.
让采购范围与交付范围一致Align procurement and delivery
报价中分别说明软件使用、实施配置、接口工作、模型或算力成本和持续服务。审查与比对组合采购时，应说明是两款产品组合授权，还是已经完成统一部署与数据衔接。Separate software use, implementation, interfaces, model or compute costs and support. For a bundle, specify whether this is combined licensing or an integrated deployment.
把样本范围、验收方法、客户配合与维护责任写清楚，才能将产品能力转化为实际工作中可持续使用的能力。Define sample scope, acceptance methods, customer responsibilities and support so product capabilities can translate into sustainable work practices.
