README

jsrpc-skill — Claude Code / Agent Skill

**English** · [中文](README.zh.md)

*Fewest parameters registered. Most variables controlled.*

A [Claude Code](https://docs.claude.com/en/docs/claude-code) skill for the **JS 逆向远程调用 (RPC)** workflow: drive a real browser as a live JS execution engine over WebSocket, and call a site's own encryption / signing / token functions through simple HTTP endpoints — no algorithm extraction, no environment patching.

Built on top of [`jxhczhl/JsRpc`](https://github.com/jxhczhl/JsRpc) (Go WebSocket server + injectable browser JS client).

What it does

When a target's front-end crypto is too heavy to reverse (WASM, obfuscation, jsvmp, fingerprint/anti-bot), you inject a small client into the page, register the site's own `sign`/`encrypt` function as an action, and call it from Python/curl. The browser does the work; you get the result.

This skill gives Claude a verified, phase-gated workflow for that: **locate → serve+inject → call → re-verify → harden**, with anti-hallucination checkpoints (every claim of success must show a real HTTP response).

Install

git clone https://github.com/heart147/jsrpc-skill
cp -r jsrpc-skill/jsrpc-skill ~/.claude/skills/jsrpc-skill

Then in Claude Code, invoke with `/jsrpc-skill` or just describe a JS-reversing task.
