devlab-dao-sql-compat

devlab-dao-sql-compat is a skill for Claude Code, Codex from seed-forge/harness-ai-kit. It costs 160 tokens per session (2,455 once invoked), scanned A, original, Apache-2.0.

A workflow for finding and fixing SQL dialect differences in the data-access layer of an application. SQL is the language used to query databases, and Oracle, PostgreSQL, and MySQL each have variations; the workflow supports MyBatis, JPA, MyBatis-Plus, and SQLAlchemy.

In plain words
What is it for?
Use it to scan source code, identify database-specific SQL, apply supported conversions between the three databases, rescan the result, and list changes needing human review.
Why use it?
It helps prevent database migrations or multi-database support from failing because the same query syntax does not work everywhere.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devlab-dao-sql-compat scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/adapters/jpa.sh, scripts/adapters/mybatis-plus.sh, scripts/adapters/mybatis.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

用途

面向使用任何持久层框架（MyBatis / JPA / MyBatis-Plus / SQLAlchemy）的项目，解决"同一套 DAO 代码需要运行在不同数据库（Oracle / PostgreSQL / MySQL）"或"数据库迁移"场景下的 SQL 方言兼容性问题：

  • 检查：通过 adapter 模式扫描框架专属源码文件，按模块输出三方言命中矩阵与风险分级
  • 修复：AI 按转换方向加载对应映射表（references/dialects/），逐模块修复
  • 验证：静态复扫必做，库级语法预检可选，明确降级声明
  • 记录：输出前后对比与待人工复核清单

支持三方言全对称 6 个转换方向：O→PG、PG→O、O→MySQL、MySQL→O、PG→MySQL、MySQL→PG。

框架探测

本技能支持 4 种 DAO 框架的 adapter，默认自动探测：

检测特征 判定框架 扫描目标
**/mapper/**/*.xml 含 SQL 标签 MyBatis Mapper XML
**/*.java 含 @Query / @NamedQuery JPA/Hibernate Java 源码
**/*.java 含 QueryWrapper / LambdaQueryWrapper / BaseMapper MyBatis-Plus Java + XML
**/*.py 含 text() / .execute() / session.execute SQLAlchemy Python 源码
多个命中 提示用户选择 monorepo 可能多框架

也可手动指定：bash scripts/scan-sql-compat.sh --adapter mybatis

各框架的扫描模式、提取逻辑和方言陷阱详见 references/adapters/ 下对应文档。

配置上下文

本 Skill 的运行时配置遵循 harness-ai-kit 配置治理规范的三级优先级：

L3 对话中用户明确声明的参数 > L2 用户配置（~/.harness-ai-kit/config.yaml → 环境变量 → ~/.harness-ai-kit/.env.tak）> L1 本目录 config.defaults.yaml

配置项见 config.defaults.yaml：adapter / scan_dir / module_glob / report_path / custom_procs_file / fail_on_critical / verify_jdbc_url。 其中 verify_jdbc_url 为 sensitive：无默认值，只能经 L2/L3 注入，禁止写入任何文档或提交。

工作流（七阶段）

Phase 0 环境确认

  1. 确认 DAO 框架类型（auto-detect 或手动 --adapter）
  2. 确认扫描根目录（scan_dir）；框架专属源码位置默认自动探测，非标准布局时向用户确认 module_glob
  3. 向用户确认目标方言拓扑（二选一）：
    • 单一目标库：整个项目最终只跑一种数据库 → 所有非目标方言都是待修复项
    • 多库路由：不同模块路由到不同数据库 → 逐模块建立"模块 → 目标方言"映射表
  4. 询问是否有自定义存储过程/函数（写入 custom_procs_file 清单）

Phase 1 扫描

bash <本Skill目录>/scripts/scan-sql-compat.sh \
  --adapter <auto|mybatis|jpa|mybatis-plus|sqlalchemy> \
  --dir <scan_dir> [--module-glob <glob>] [--procs <file>] --report <report_path>

产出报告含：三方言命中明细、模块级风险矩阵、自定义存储过程依赖。 风险等级：CRITICAL（同模块方言混用）/ HIGH（单方言文件数 >5）/ MEDIUM（单方言文件数 ≤5）。

Phase 2 范围决策

向用户呈现风险矩阵，确认本次修复范围（CRITICAL 优先，或用户指定模块）。禁止全量静默修复。
