Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00011 | $0.01948 |
| Opus 5 | $0.00005 | $0.00974 |
| Sonnet 5 | $0.00002 | $0.00390 |
| Haiku 4.5 | $0.00001 | $0.00195 |
Grade A, and why
pdlc-db-migrate 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 11d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.
数据库迁移管理
根据 db-design 文档管理数据库迁移脚本,支持生成、执行、回滚和状态查看。
子命令解析
从 $ARGUMENTS 中解析子命令和参数:
| 子命令 | 格式 | 说明 |
|---|---|---|
generate <描述> |
根据 db-design 文档生成版本化迁移脚本(up + down) | |
status |
查看迁移状态,列出已执行/待执行的迁移 | |
up |
执行所有待执行的迁移 | |
down [N] |
回滚最近 N 个迁移(默认 1) | |
diff <功能名> |
对比 db-design 文档与现有迁移脚本,生成增量迁移 |
如果未提供子命令或子命令无法识别,输出以上帮助信息后停止。
PDLC 前置检查(仅 generate 和 diff 子命令)
当子命令为 generate 或 diff 时执行:
- 从用户输入中提取功能名称关键词
- 在
docs/02_design/database/目录下搜索包含该关键词的数据库设计文档- 匹配新格式:
F<日期>-<编号>-*<关键词>*-db.md - 匹配旧格式:
YYYYMMDD-*<关键词>*-db.md - 同时检查文件内容中是否包含该关键词
- 匹配新格式:
- 未找到 → 输出以下信息后立即停止,不继续执行:
⛔ PDLC 守卫:未找到与「<功能名>」相关的数据库设计文档。 迁移脚本必须基于已有的数据库设计。请先运行: 👉 /pdlc-db-design <设计目标> - 找到 → 提取功能ID(如
F20260326-090000),读取该设计文档内容,继续执行
迁移文件约定
目录结构
- 微服务项目:
backend/services/<service>/migrations/ - 单服务项目:
migrations/ - 自动检测:如果存在
backend/services/目录,按微服务项目处理;否则按单服务项目处理
文件命名
- UP 脚本:
V<版本号>__<描述>.sql - DOWN 脚本(回滚):
R<版本号>__<描述>.sql - 版本号格式:
YYYYMMDD_HHMMSS(如20260402_143052)
文件头部注释
每个迁移文件必须包含以下头部注释:
-- ==============================================
-- 迁移脚本: V20260402_143052__create_users_table.sql
-- 功能ID: F20260402-090000
-- 描述: 创建用户表
-- 作者: <从 git config 获取>
-- 日期: 2026-04-02
-- ==============================================
子命令执行流程
generate <描述>
- 执行前置检查,读取 db-design 文档
- 读取
.claude/templates/pdlc/db-migrate-template.md模板 - 生成版本号:使用当前时间戳
YYYYMMDD_HHMMSS - 从 db-design 文档中提取 DDL 脚本和回滚脚本
- 生成 UP 迁移文件:
V<版本号>__<描述>.sql- 包含头部注释
- 包含 CREATE TABLE / ALTER TABLE / INSERT 等语句
- 每条语句末尾添加分号
- 生成 DOWN 迁移文件:
R<版本号>__<描述>.sql- 包含头部注释
- 包含对应的回滚操作(DROP TABLE / ALTER TABLE DROP COLUMN 等)
- 操作顺序与 UP 相反
- 更新迁移历史记录文件
migrations/migration_history.md - 输出生成结果摘要
status
-
查找迁移目录下所有
V*.sql文件 -
读取
migrations/migration_history.md(如不存在则提示无迁移记录) -
输出迁移状态表格:
📋 迁移状态 | 版本号 | 描述 | 功能ID | 状态 | 执行时间 | |--------|------|--------|------|----------| | 20260402_143052 | 创建用户表 | F20260402-090000 | ✅ 已执行 | 2026-04-02 14:35 | | 20260402_150000 | 添加订单表 | F20260402-100000 | ⏳ 待执行 | - | 已执行: 1 | 待执行: 1 | 总计: 2
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 199 lines · 11 tokens per session scan A 94ffc1c56f07
pdlc-db-migrate is a skill published in the GitHub repository kanfu-panda/pdlc-skills (13 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 1,948 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
