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 5.1 | $0.00100 | $0.04106 |
| Opus 5.5 | $0.00040 | $0.01642 |
| Sonnet 5.5 | $0.00020 | $0.00821 |
| Haiku 4.5 | $0.00010 | $0.00411 |
Grade A, and why
claude-code-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 1mo 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code 到 sid-code 迁移
只用于 Claude Code -> sid-code。首要目标是保护用户现有环境：只 copy，不 move；不删除源文件；不静默覆盖目标文件。
不可违反的规则
- 先做只读检查。 展示迁移计划前，不写文件、不运行安装命令。
- 默认使用用户启动 sid-code 的当前目录作为项目上下文。如果
~/.claude.json里有多个项目条目匹配，先让用户选择。 - 所有写入前都要用户确认。 高风险资源单独确认：permissions、hooks、MCP secrets/env/headers、env 字段，以及所有冲突。
- 迁移计划和确认问题必须按 scope 拆开说明：用户级、项目共享级、项目本地级分别迁移哪些、跳过哪些、写到哪里。
- 不迁移 auth state、OAuth/session 文件、managed/policy settings、trust caches 或未知 state/cache 文件。
- 只写入
references/mapping.md列出的目标文件；不要创建未列出的 sid-code 配置文件。 - 允许写入迁移状态文件
~/.sid-code/state/cc-migration-state.json（inspector 的默认--state路径）。它是本 skill 的记账文件，不是 sid-code 运行时配置；只记录已迁移项的标识（scope、目标路径或目标#mcpServers.name、时间戳、项目路径），绝不写入 secret / env / headers 值。绝不触碰~/.sid-code/state/migrations.json——那是 sid-code 内核 schema 迁移的版本水位线文件。 - 未知、不支持、无效和空字段默认只报告；除非
references/mapping.md明确写了迁移方式。 - 无论是否实际写入，最后都要生成迁移报告。
写入 settings.json 的硬性约束
绝不整体覆盖写 sid-code 的 settings.json。 只做「新增缺失的顶层字段/嵌套键」的 patch 式合并：读入现有 JSON → 只添加计划里确认的字段 → 写回。原因：sid-code 的 settings 经 Zod round-trip 整体重写会 strip 掉嵌套字段（如 availableModels[].apiKey）并把 ${ENV} 占位符展开成明文落盘。若目标字段已存在，走冲突流程，不覆盖。
JSON 合并的硬性约束（settings.json / .mcp.json）
绝不即兴写临时脚本（如 /tmp/*.mjs、/tmp/*.js）来做 JSON 合并。 这类做法反复出问题：临时脚本用错模块系统（.mjs 里写 require 直接崩）、或改走 write 工具把整段 JSON 当字符串塞进去被参数校验拒绝。JSON 的 patch 合并、type→transport 转换等确定性变换一律交给 skill 自带的确定性脚本，你只负责调用它、传参、读它的 JSON 结果：
# settings.json patch 合并（只新增缺失键，冲突默认跳过并报告，不覆盖已有键与嵌套 apiKey）
node <skill-dir>/scripts/apply-migration.mjs --op merge-settings --target <settings.json> --patch '<json>'
# MCP 合并（自动做 type→transport、disabled→enabled、丢弃不支持字段；已存在的 server 名算冲突跳过）
node <skill-dir>/scripts/apply-migration.mjs --op merge-mcp --target <.mcp.json 或 settings.json> --servers '<json>'
- patch/servers 过长时改用
--patch-file <path>/--servers-file <path>从文件读，避免超长命令行。 - 想先看结果不落盘：加
--dry-run，脚本会把合并后的完整对象放在返回 JSON 的result字段里。 - 需要覆盖已有键时（仅在用户明确选择"覆盖"冲突处理方式后）：加
--on-conflict overwrite。 - 脚本返回 JSON：
{ ok, written, added:[], conflicts:[], transforms:[] }。据conflicts走冲突确认流程，据transforms向用户交代做了哪些转换。 - 与 inspector 一样，脚本用
node或bun都能跑（见下方运行时探测）。
What ships with it
3 files 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.

claude-code-migration is a skill published in the GitHub repository rushengzhou/sid-code (2 stars, last pushed 1mo ago), licensed MIT. It adds 100 tokens to every session and 4,106 once invoked, about $0.0004 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.
