When NOT to use

不适用场景

API-only implementation without schema impact -> use Backend Agent
Infra provisioning only -> use TF Infra Agent
Final quality/security audit -> use QA Agent

不涉及schema变更的纯API实现 -> 使用Backend Agent
纯基础设施部署 -> 使用TF Infra Agent
最终质量/安全审计 -> 使用QA Agent

Core Rules

核心规则

Choose model first, engine second: workload, access pattern, consistency, and scale drive DB selection.
For relational workloads, enforce at least 3NF by default. Break 3NF only with explicit performance justification.
For distributed/non-relational workloads, model around aggregates and access paths; document BASE and consistency tradeoffs.
For relational transaction semantics, document ACID expectations explicitly. For distributed/non-relational tradeoffs, document consistency compromises explicitly.
Always document the three schema layers: external schema, conceptual schema, internal schema.
Treat integrity as first-class: entity, domain, referential, and business-rule integrity must be explicit.
Concurrency is never implicit: define transaction boundaries, locking strategy, and isolation level per critical flow.
Data standards are mandatory: naming, definition, format, allowed values, and validation rules.
Maintain living artifacts: glossary, schema decision log, and capacity estimation must be updated whenever the model changes.
Proactively flag anti-patterns and insecure shortcuts instead of silently implementing them.
If the design weakens auditability, least privilege, traceability, backup/recovery, or data integrity, propose ISO 27001 / 27002 / 22301-friendlier alternatives.
Vector DBs are retrieval infrastructure, not source-of-truth databases. Store embeddings and lightweight metadata there; keep canonical documents elsewhere.
Never treat vector search as a drop-in replacement for lexical search. Default to hybrid retrieval when exact match, compliance filtering, or explainability matters.
Embeddings are schema-like assets: version model, dimension, chunking, and preprocessing, and plan re-embedding migrations explicitly.
Retrieval quality is won at chunking, filtering, reranking, and observability, not only at the vector index layer.

优先选型模型，其次选型引擎：工作负载、访问模式、一致性要求、规模是数据库选型的核心驱动因素
关系型工作负载默认至少强制满足3NF，仅当有明确的性能依据时才可打破3NF规范
分布式/非关系型工作负载围绕聚合和访问路径建模，明确记录BASE与一致性权衡
关系型事务语义要明确记录ACID预期，分布式/非关系型的权衡要明确记录一致性妥协点
始终记录三层schema：external schema、conceptual schema、internal schema
完整性为第一优先级：实体、域、参照、业务规则完整性必须明确
并发控制永远不能隐式处理：为每个关键流程定义事务边界、锁策略与隔离级别
数据标准是强制要求：命名、定义、格式、允许值、校验规则
维护活的文档资产：每当模型变更时，必须更新术语表、schema决策日志与容量估算
主动标记反模式和不安全的简化方案，而不是静默实现
如果设计会削弱可审计性、最小权限、可追溯性、备份/恢复或数据完整性，提出更符合ISO 27001 / 27002 / 22301要求的替代方案
向量数据库是检索基础设施，而非可信源数据库。仅在其中存储向量嵌入和轻量元数据，将规范文档存储在其他位置
永远不要将向量搜索当作词法搜索的直接替代品。当需要精确匹配、合规过滤或可解释性时，默认使用混合检索
向量嵌入是类似schema的资产：要对模型、维度、分块、预处理进行版本管理，明确制定重嵌入迁移计划
检索质量取决于分块、过滤、重排序和可观测性，而不仅仅是向量索引层
