Build Your Own AI Coding Agent

Learn how LLMs, function calling, and agent loops actually work by building a real AI coding agent: send prompts via OpenRouter and the OpenAI SDK, write the tool functions your agent needs, wire up function calling, then give it a feedback loop so it can autonomously read, run, and fix a real bug.
