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 | $0.00034 | $0.03687 |
| Opus 5.5 | $0.00014 | $0.01475 |
| Sonnet 5.5 | $0.00007 | $0.00737 |
| Haiku 4.5 | $0.00003 | $0.00369 |
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 13d 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.

数据库迁移管理
⛔ IRON LAW · 不可违反的硬门禁（工具型命令）
本命令不是主链路上的阶段：不追加 history，不改 current_stage / next_step / last_phase_result，也不为此分配功能ID。以下规则不可协商：
- 文件必须落盘：正文要求创建的文件必须作为实际文件写入磁盘，不可仅在对话中输出（只要求在对话里输出的，照正文办）。
- 自检必须执行：产出后按本命令的自检项逐项核对，不得以"已经很好了"为由跳过。
- 防循环：修复只做一次，不递归。修不了的问题记进报告，继续往下走。
违反任一条 = 立即中止当前命令，输出违规详情，等待人工介入。
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
从本命令的参数中解析子命令和选项：
| 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
先探测项目布局（不要套用写死的目录）
下文出现的 backend/services/、frontend/web/ 等路径只是空项目时的默认布局。动手创建或扫描目录之前，先看项目实际长什么样：
- monorepo 标志：
pnpm-workspace.yaml、turbo.json、nx.json、lerna.json、package.json的workspaces、go.work、Cargo.toml的[workspace]、settings.gradle(.kts)的include→ 按其中声明的目录（如apps/、packages/、services/、crates/）理解布局 - 已有单元的位置：在
backend/services/、services/、apps/、packages/、cmd/、crates/下找已存在的服务 / 应用，新单元放在同级，命名与目录结构照着已有的来 - 单体与全栈框架：只有一个
src/，或是框架默认结构（manage.py+ 各 app、Rails 的app/、Next.js 的app//pages/、Spring Boot 单模块）→ 按框架约定放，不要新建services/一类平行目录 - 空项目或判断不了 → 才用下文的默认布局；执行前把将要创建的路径列给用户确认（
--autonomous下记入auto_decisions[]）
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pdlc-db-migrate is a skill published in the GitHub repository kanfu-panda/pdlc-skills (18 stars, last pushed 13d ago), licensed MIT. It adds 34 tokens to every session and 3,687 once invoked, about $0.0001 per session on Opus 5.5. 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.
