What it does
MCP JS Reverse Playbook is an agent skill from haikow/claude-reverse-skills. 在使用 js-reverse-mcp 做前端 JavaScript 逆向时使用，适用于签名链路定位、页面观察取证、运行时采样、本地补环境复现与证据化输出。优先适配当前环境里的 js-reverse 工具。
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including reference files (for example `references/ast-deobfuscation.md`, `references/automation-entry.md` and `references/env-patching.md`).
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol and JavaScript. The repository describes itself as: Claude Code 逆向工程 skill 集合 (apk/ida/radare2/js) + IDA MCP 接入，跨平台 Linux/Mac/Windows.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/mcp-js-reverse-playbook”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Observe
- Capture
- Rebuild
- Patch

What it can do on your machine
Read from SKILL.md and the folder at commit 8491b3b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
MCP JS Reverse Playbook loads about 771 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 32 tokens; SKILL.md has 166 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
