Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

铁律:不要在没有确认输入校验、权限边界和数据写入规则前直接写后端逻辑。
工作流
- [ ] Step 1: 建立后端上下文 ⚠️ REQUIRED
- [ ] 1.1 阅读目标路由、服务层、schema 和相关数据模型。
- [ ] 1.2 确认当前项目使用的后端模式是 Hono、Nuxt server routes 还是自定义服务层。
- [ ] Step 2: 明确接口契约 ⚠️ REQUIRED
- [ ] 2.1 先定义输入、输出、错误语义和边界条件。
- [ ] 2.2 明确是否需要分页、排序、过滤、幂等或事务。
- [ ] Step 3: 处理安全与数据一致性
- [ ] 3.1 先做鉴权和权限检查,再进入业务逻辑。
- [ ] 3.2 输入校验优先于数据库操作。
- [ ] 3.3 数据写入必须避免拼接查询、隐式权限绕过和部分写入。
- [ ] Step 4: 实现与验证
- [ ] 4.1 给出语义清晰的错误处理。
- [ ] 4.2 如果改动可测,补齐对应测试或至少指出缺失测试点。
- [ ] 4.3 涉及高风险改动时,建议联动 security-guardian 与 test-engineer。
关注点
- 输入校验是否覆盖空值、非法值和边界值。
- 鉴权是否在真正敏感操作前完成。
- 数据访问是否参数化、可回滚、可追踪。
- 错误是否对用户和日志分别提供恰当信息。
项目特化提示
- 如果项目使用 Nuxt server routes,优先遵循 defineEventHandler 和 createError 的惯用模式。
- 如果项目已有 Zod、Drizzle ORM、TypeORM、Better-Auth 或权限中间件,优先复用,而不是临时发明另一套接口层。
- 列表接口要考虑 ApiResponse 风格、分页和可扩展过滤条件。
- 权限检查优先放在 handler 或服务入口,而不是散落在内部步骤中。
反模式
- 先写 SQL 或 ORM 调用,再回头补校验与权限控制。
- 把控制器、业务逻辑、数据访问全部塞进一个文件。
- 用宽泛 catch 吞掉错误上下文。
- 对列表接口忽略分页与性能成本。
交付前检查
- [ ] 输入、输出和错误语义已经明确。
- [ ] 鉴权、权限和数据写入顺序正确。
- [ ] 未引入字符串拼接查询或隐式越权。
- [ ] 已说明需要的测试或后续验证。
