pandas-studio/agent-harness-tutorial — reverse-engineered prompt

Build me a small Korean tutorial repository for practicing teamwork between Claude Code, Codex CLI, and Gemini CLI.

The goal is that a learner can clone it, follow setup instructions, authenticate the three tools, then open a demo folder and run a guided exercise where the three coding agents review a FastAPI codebase together. Please create a clear main README in Korean with the project purpose, demo table, setup link, folder structure explanation, and license warning. Add a SETUP guide that explains prerequisites in friendly steps without assuming much experience.

Put each exercise in its own independent episode folder, starting with an episode A development demo and leaving room for a conductor style demo. Include the small sample app, scripts, and exercise README needed so someone can follow along without guessing. Keep it educational, not commercial, and add license and notice files for personal learning use.
