仓库合同模板
适用场景：后端仓库还没有稳定 AGENTS.md，或需要把长期规则从聊天里回写成仓库真相。
## Backend Engineering Rules
- Keep API contracts explicit and versioned.
- Require schema or migration review for every persistent-data change.
- Do not merge new external integrations without timeout, retry, and idempotency rules.
- Treat lint, type-check, integration tests, and smoke paths as required release evidence.
- Use structured logs, request IDs, and traceable background-job identifiers.
- Document rollback conditions for migrations, config changes, and async consumers.
至少再补两件事
| 补什么 | 为什么 |
|---|---|
| 目录边界 | 不写清 controller / service / repository / job 的边界，agent 很快会越层改动 |
| 发布与回滚纪律 | 不写清 smoke、告警和 rollback，PR 只会停在“测试通过” |
