How to reverse engineer any closed-source AI coding tool prompts: This works for Claude Code, Windsurf, Copilot and literally anything by intercepting their calls Method 1: Charles Proxy (for tools with internal endpoints) Tools like Vscode Extension route to their own backend first. - Install Charles Proxy - Install the Charles root certificate - Watch the traffic - Find the internal endpoint they're hitting - Mark it for SSL proxying in Charles - Read everything Method 2: Local proxy (for tools calling LLM APIs directly) - Tools like Cline, Claude Code call directly. Charles won't work as cert pinning blocks it. - Spin up a local proxy on localhost:8080 - Configure the extension to use that as its API base URL - Your proxy forwards to the real API - Read everything in plaintext - You're not intercepting as you ARE the endpoint so no cert issues. With this you will see full system prompts, tool definitions, conversation structure, parameters, everything.
