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 | $0.00080 | $0.02908 |
| Opus 5.5 | $0.00032 | $0.01163 |
| Sonnet 5.5 | $0.00016 | $0.00582 |
| Haiku 4.5 | $0.00008 | $0.00291 |
Grade A, and why
js-reverse 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 3d 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.

MCP 前端 JS 逆向作业规范
OMP 已捕获签名复现
已有真实捕获样本和待对照的签名函数、当前 OMP 暴露 JS eval 时，先读 omp-js-replay。它复用持久 JS 环境，输出样本逐项对照与覆盖信息；本次实现尚未测试。若仍需定位函数或采集请求，先使用下文当前可用的浏览器/MCP 工具取得证据，再进入复现入口。签名匹配不代表新请求已获服务器接受。
适用范围
当任务属于以下场景时优先使用本 skill：
- 定位接口签名、加密参数、风控字段
- 观察页面请求链路与脚本来源
- 在运行时抓取函数入参与返回值
- 追踪某个 XHR/Fetch/WebSocket 的触发点
- 把页面证据带回 Node 做本地复现与补环境
如果目标是二进制、APK、PE、ELF、DLL、SO，请改用 ida-reverse、radare2 或 reverse-engineering。
当前环境默认工具映射
本 skill 不假设存在裸工具名，而是默认绑定当前客户端环境里可用的 js-reverse_* 工具。
如果当前任务明确提到 jshookmcp、JS hook、CDP、浏览器断点、网络拦截、SourceMap 或 AST 去混淆，也仍然走本 skill；只是把底层 MCP 面切到 jshookmcp，而不是把它当成一个新的总入口。
前提条件：jshookmcp 不是本地裸命令工具，而是一个要先下载/注册/启用的 MCP server。只有在 Claude MCP 配置里接入并启用后，相关工具面才真的可调用。
常用映射：
list_scripts->js-reverse_list_scriptsget_script_source->js-reverse_get_script_sourcesearch_in_sources->js-reverse_search_in_sourcesbreak_on_xhr->js-reverse_break_on_xhrevaluate_script->js-reverse_evaluate_scriptget_paused_info->js-reverse_get_paused_infoset_breakpoint_on_text->js-reverse_set_breakpoint_on_textlist_network_requests->js-reverse_list_network_requestsget_request_initiator->js-reverse_get_request_initiatorget_websocket_messages->js-reverse_get_websocket_messagestake_screenshot->js-reverse_take_screenshotnew_page->js-reverse_new_pagenavigate_page->js-reverse_navigate_pageselect_page->js-reverse_select_pageselect_frame->js-reverse_select_framepause/resume->js-reverse_pause_or_resume
如果未来工具名前缀变化，先更新本节，不要在执行时临时猜测。
jshookmcp 的定位
- 角色：
js-reverse的增强执行面，不是独立总控 - 适合：浏览器自动化、CDP 调试、JS Hook、网络拦截、SourceMap 重建、AST 辅助理解
- 调用前提：先把
@jshookmcp/jshook下载并注册到 MCP 客户端配置里，然后确保该 server 已启用 - 建议入口：仍然按
Observe → Capture → Rebuild执行，只是在Observe/Capture阶段优先调用 jshookmcp 的浏览器与 Hook 能力 - 与 anything-analyzer 关系：两者都能做浏览器/网络侧取证；anything-analyzer 更偏抓包与 HTTP 分析，jshookmcp 更偏 JS 运行时、CDP、Hook 和源码理解

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.

js-reverse is a skill published in the GitHub repository 2233admin/reverse-skill-evolver (17 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 2,908 once invoked, about $0.0003 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 2026-08-30.
