What problem does it solve?

This Skill helps you recover the real logic behind obfuscated or encrypted frontend JavaScript by observing, interrupting, and extracting runtime behavior directly in a real browser session.

Core Features & Use Cases

• Script & Evidence Collection: Locate loaded scripts, retrieve their sources, and capture runtime evidence (scripts, network, hooks, and environment artifacts) for later reconstruction.
• Function Hooking & Call Tracing: Hook target functions (including crypto-related calls), capture arguments/returns/stacks, and trace call chains to identify where key parameters are generated.
• Breakpoints, Network Tracing & Deobfuscation: Use breakpoints and request tracing to correlate execution with outgoing traffic, then deobfuscate and understand the extracted code for API signature or request parameter logic.

Quick Start

Use the jsreverser-mcp-javascript-reverse-engineering skill to connect to a Chrome instance with remote debugging, navigate to the target page, then ask it to trace and deobfuscate how the site generates the encrypted or signed request parameters.
