jsrpc-universal

What problem does it solve?

Reverse engineering complex, obfuscated, or environment-dependent algorithms often requires extracting source code, mocking runtime environments (such as browser DOM or native app contexts), or reimplementing logic from scratch — all of which are time-consuming, fragile, and break when the target algorithm updates. This Skill eliminates that overhead by letting you invoke the target algorithm directly in its original running environment via RPC.

Core Features & Use Cases

• Dual-framework support: Natively supports jxhczhl/JsRpc (lightweight, browser-focused RPC) and yint-tech/sekiro-open (production-grade cross-platform RPC for web and Android) to fit different project scale and platform requirements.
• Multi-platform injection guidance: Covers injection methods for browser targets (console, Tampermonkey) and Android targets (Frida, Xposed), with recommendations for selecting the right approach based on anti-debugging strength and stability needs.
• Workflow decision support: Provides a clear comparison of JsRpc vs pure algorithm reimplementation vs node environment mocking, so you can choose the most efficient path for your specific use case.
• Operational best practices: Includes guidance on client routing, concurrency scaling, timeout troubleshooting, and security configuration to avoid common pitfalls like endpoint exposure or request mismatches.

Quick Start

Use the jsrpc-universal skill to remotely invoke a target site's request signing algorithm via RPC without extracting or reimplementing its source code.
