How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Browser Extension Reverse Engineering
ACTION REQUIRED(读完后立刻执行)
NOW: 读取../field-journal/precedent-reverse.mdNOW: 确认目标是浏览器扩展(crx/xpi/解压目录),不是普通网页 JS(普通 →js-reverse/)NEXT: 解压扩展;读 manifestACT: 权限面 → 后台脚本 → 网络/存储钩子
适用场景
- Chrome/Edge MV2/MV3 扩展分析
- Firefox 扩展
- 恶意扩展 IOC、供应链扩展投毒调查
- 扩展实现的签名/加密/代理逻辑还原
工作流
1. 包体
□ crx 解压 / 从 profile 取扩展目录
□ manifest.json:permissions、host_permissions、background、content_scripts
□ 评估过度权限(<all_urls>、webRequest、debugger)2. 逻辑
□ service_worker / background 入口
□ content_script 注入点与世界(isolated)
□ chrome.storage / IndexedDB 密钥
□ 与 `js-reverse` 相同:Observe 网络与消息传递(runtime.sendMessage)3. 动态
□ 开发者模式加载解压目录
□ chrome://extensions 检查错误
□ DevTools 附加 service worker
□ 必要时 Frida/浏览器 CDP(jshookmcp)工具链
| 工具 | 用途 |
| 解压/jq | manifest |
| Chrome DevTools | worker 调试 |
| js-reverse 工具链 | 深度 JS |
| YARA | 恶意扩展规则 |

路由上下文
上游: MASTER R30
下游: 复杂混淆 JS → js-reverse;投毒调查 → supply-chain / malware

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
