claude-source-binary-analysis SKILL.md skillA
claude-source-binary-analysis from esonhugh/claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add esonhugh/claude-code/claude-source-binary-analysis@v0.2.0Pins v0.2.0 in mdr.lock. Pin the fingerprint instead.

This skill should be used when the user asks to statically analyze authorized Claude Code source or official-claude/built-claude binaries, extract Bun .bun or __BUN,__bun sections and cli.original.js, improve extracted JavaScript readability with webcrack/restringer, inspect symbols or sections with objdump/nm/otool, perform read-only local Frida observation, compare source and binary behavior, or reproduce the offline CCH checksum for an authorized fixture. Use claude-runtime-debug for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Code 源码与二进制分析
## 目的
用于在明确授权边界内分析官方 `claude-code` 源码仓库，以及 `official-claude` / `built-claude` 二进制。分析时应保持证据来源清晰、假设最少、边界明确。
此 skill 适用于仓库所有者有权测试、调试、提取和检查程序行为的合法分析场景。工作范围应聚焦于理解运行时逻辑、构建产物、兼容性和 checksum 行为。
## 必要流程
1. 确认目标位于 `{PROJECT_ROOT}` 内，或属于官方 Claude Code 源码产物，或是仓库所有者明确授权分析的二进制。
2. 使用二进制或反混淆工具前，先说明分析目标：提取、符号检查、运行时观察、checksum 复现或源码/二进制一致性分析。
3. 优先使用源码证据。只有源码不足以回答问题时，再使用二进制工具补充证据。
4. 提取产物仅保留在本地。不要把私有代码、日志、二进制、请求体或提取出的 JavaScript 上传到第三方服务。
5. 记录结论时标注证据类型：
- `Source-confirmed`
- `Binary-observed`
- `Runtime-observed`
- `Inference / needs verification`
6. 除非用户明确要求本地授权实验，否则不要修改二进制行为。不得提供绕过、持久化、凭证窃取、数据外传或隐蔽规避指导。
## Reference map
按任务只读取需要的 reference：
- [`references/source-analysis.md`](references/source-analysis.md) — 源码入口、调用链、配置/状态来源、测试证据和动态验证升级条件。
- [`references/js-extraction.md`](references/js-extraction.md) — `webcrack`、`restringer`、[`scripts/native-extra.mjs`](scripts/native-extra.mjs) 和 Bun standalone JS 提取。
- [`references/binary-debugging.md`](references/binary-debugging.md) — `objdump`、`nm`、`otool`，以及对 `official-claude` 二进制的安全本地 Frida 观察。

How to install
mdr add esonhugh/claude-code/claude-source-binary-analysis@sha256:1ec90ac1801f44f7The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
