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.

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 | $0.00026 | $0.00361 |
| Opus 5 | $0.00013 | $0.00180 |
| Sonnet 5 | $0.00005 | $0.00072 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
db-migration 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 3d 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.
What it actually says
db-migration — 数据库 schema 变更
用户输入 /db-migration $ARGUMENTS 触发 硬刹车级动作流程。
立刻读取并完整加载:
~/.claude/prompts/lib/01-启动/数据库schema变更.md
按其"行为契约"段严格执行 6 步:
- 列影响范围(类型 / 表 / 列 / 行数 / 依赖代码 / 依赖外部)
- 风险评估(锁表 / 兼容 / 可逆 / 幂等 / replica lag / 流量影响)
- 写 forward + rollback 双向 migration(都写,绝不只写 forward)
- Expand-and-Contract 模式(高风险变更必走两步,禁止单次部署里 expand + contract)
- staging dry-run(时长 / 锁 / 完整性 / 老代码兼容)
- 生产前:备份 + 低峰期 + rollback 备好 + 监控开
参数含修饰符 → 叠加对应文件。
核心契约:任何 ALTER / DROP 既有列 / backfill UPDATE → 触发硬刹车 #4,必须列 diff + 等用户 yes。任何失败立即 rollback,禁止在生产 patch SQL。
参数: $ARGUMENTS
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.

db-migration is a command published in the GitHub repository xcodethink/open-claude-code-skills (2 stars, last pushed 28d ago), licensed MIT. It adds 26 tokens to every session and 361 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.
