migrate

A command for migrating or rewriting software, such as moving Python code to Go, upgrading to version 2, or changing frameworks. It first creates a complete inventory of the existing system.

In plain words
What is it for?
Use it to catalogue files, features, endpoints, middleware, scheduled tasks, and environment variables before a migration, then verify the rewritten system against that catalogue.
Why use it?
Migrations can silently lose endpoints, middleware, scheduled jobs, or environment settings. The inventory and later comparison help check that the new version remains functionally equivalent.

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.

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

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 2d 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

migrate — 代码迁移 / 重写

用户输入 /migrate $ARGUMENTS 触发 先清点对等再动手的迁移流程。

立刻读取并完整加载: ~/.claude/prompts/lib/01-启动/迁移重写.md

按其"行为契约"段严格执行:

  1. 必先做源码全量清点(文件 + 功能 + 端点 + 中间件 + 定时任务 + 环境变量)
  2. 清点表 → 等用户确认后才能动手写代码
  3. 写完必须做功能对等验证(逐项对照清点表)
  4. 完成率 < 95% 必须说明原因,不允许蒙混过关

参数含修饰符 → 叠加对应文件。

核心契约:迁移前不清点 = 凭记忆做,会漏端点 / 漏 cron / 漏 middleware。清点 + 对等验证缺一不可。

参数: $ARGUMENTS

Changes

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.

migrate is a command published in the GitHub repository xcodethink/open-claude-code-skills (2 stars, last pushed 27d ago), licensed MIT. It adds 31 tokens to every session and 288 once invoked, about $0.0002 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.
