Analyze authorized browser extensions for Chrome, Edge, and Firefox. Inspect permissions, background scripts, storage, and network activity to reconstruct key data flows and explain credential handling, signing, encryption, or proxy behavior.
Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.
Review the instructions the agent will receive before you install.
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□ 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）
□ 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）
□ 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）

Assess authorized APIs through a ten-stage workflow covering endpoint discovery, authentication, access permissions, input handling, and request limits. Collect reproducible evidence and turn findings into regression checks that can run in a development pipeline.
Inspect Android APKs from the command line to understand app logic, permissions, and components. Supports Java decompilation, low-level code edits, rebuilding and signing, plus Frida observation of running methods and routing to native code analysis.
Plan and coordinate authorized penetration tests across multiple stages, from reconnaissance to access, privilege escalation, movement between systems, and impact assessment. Assign specialist skills, revise blocked paths, and maintain evidence and progress records for the final report.
Transfer known function and variable names from an older binary to a newer version. Compare disassembly and pseudocode with an LLM, produce structured mappings, and apply names and comments in IDA.
Inspect compiled programs in Binary Ninja using strings, function references, and intermediate representations—views of program logic at different levels. Trace data flow and report findings with addresses, supporting evidence, confidence, and reproduction steps.
Automate website navigation, form filling, content collection, and Windows desktop interactions. The skill selects browser or desktop tools for the task and guides screenshot capture and desktop network traffic observation when needed.
