team-migration

team-migration is a skill for Claude Code from ketor/cto-fleet. It costs 115 tokens per session (7,474 once invoked), scanned B, original, Apache-2.0.

A coordinated workflow for planning and carrying out a technology migration, such as moving from one database or framework to another. It uses separate scanning, planning, validation, merging, and rollback checks.

In plain words
What is it for?
Use it with a source technology and target technology to create a migration plan, optionally preview the plan only, automate decisions, request one confirmation, or choose Chinese or English output.
Why use it?
It helps identify affected areas, compare independent migration plans, and prepare a staged path back if the change fails.

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 B, and why

team-migration scanned grade B with 1 finding 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 6d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 539 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

_UPD=$(~/.claude/skills/cto-fleet/bin/cto-fleet-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/cto-fleet/cto-fleet-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running cto-fleet v{to} (just updated!)" and continue.

参数解析:从 $ARGUMENTS 中检测以下标志:

  • --from=<源技术>:源技术栈(必需,如 --from=webpack--from=REST--from=MySQL
  • --to=<目标技术>:目标技术栈(必需,如 --to=vite--to=gRPC--to=PostgreSQL
  • --dry-run:仅生成迁移计划(MIGRATION.md),不执行任何代码变更
  • --auto:完全自主模式(不询问用户任何问题,全程自动决策)
  • --once:单轮确认模式(将所有需要确认的问题合并为一轮提问,确认后全程自动执行)
  • --lang=zh|en:输出语言(默认 zh 中文)

解析后将标志从迁移目标描述中移除。如缺少 --from--to,立即用 AskUserQuestion 要求用户补充。

模式 用户确认范围 条件节点处理
标准模式(默认) 固定节点 + 条件节点,全部 AskUserQuestion 正常询问用户
单轮确认模式--once 仅固定节点(影响确认、方案确认) 自动决策 + 收尾汇总
完全自主模式--auto 不询问用户 全部自动决策,收尾汇总所有决策

单轮确认模式下条件节点自动决策规则:

  • planner-1/planner-2 方案分歧 → team lead 综合两方观点裁决,在方案确认时附带争议摘要和裁决理由
  • 回滚验证失败 → validator 尝试调整回滚策略(最多 2 次),仍失败则标记为高风险,team lead 裁决
  • 迭代超 3 轮不可跳过,必须暂停问用户(熔断机制)

完全自主模式下:所有节点(包括影响确认、方案确认等固定节点)均自动决策,不询问用户。收尾时汇总所有自动决策。唯一例外:迭代超 3 轮仍自动停止(但不询问用户,而是 team lead 自行裁决是否继续)。

使用 TeamCreate 创建 team(名称格式 team-migration-{YYYYMMDD-HHmmss},如 team-migration-20260308-143022,避免多次调用冲突),你作为 team lead 按以下流程协调。

文件交接规范(File-Based Handoff)

所有 agent 间传递详细报告时,必须采用文件交接模式(防止上下文溢出触发 20MB 限制):

  1. 写入文件:将完整报告写入团队工作目录:
    • 目录路径:/tmp/{team-name}/(team lead 在 TeamCreate 后执行 mkdir -p /tmp/{team-name} && chmod 700 /tmp/{team-name}
    • 单个文件 ≤ 2000 行;超大报告拆分为 summary + details 文件
  2. 发送引用:通过 SendMessage 仅发送(≤500 字符):
    • 文件路径(1 行)
    • 关键摘要(含核心指标/发现/评分)
  3. 按需读取:接收方使用 Read 按需读取文件,发送方不内联完整内容
  4. 路径转发:team lead 转发报告时只转发文件路径 + 摘要,不 Read 后再 SendMessage
  5. 遵从校验:team lead 收到超 1000 字符且不含 /tmp/team- 路径前缀的消息时,要求 agent 以文件交接模式重发

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.
