I barely wrote the code for the bot and the website by hand. I used the coding agents Codex (OpenAI) and Claude (Anthropic), and I think the result is pretty good, right? If you want to learn how to do it as well, read the following guide.

I used the agentic coding tool "Claude Code" from Anthropic, but you can use any other one, or even a local LLM, as well (I'm not sure if they are capable enough for this right now, but maybe soon).

Once your setup is running, dig into the code. bot.log (found under runtime/logs/bot.log) is the bot's own debug output, and Player.log is MTGA's game log that the bot reads as its primary state source, both are your best friends when something breaks.
