Hi everyone,

I'm an Al Engineer and maintainer of an open source agentic IDE.

I would love to share with you my latest technical blog on how coding agents like Codex and ClaudeCode work.

In the blog, I explain the fundamental functions required for a coding agent and how to write tools and the inference loop using the OpenAl API.

If you're new to coding agents or agentic engineering, this is a very friendly introductory guide with step by step code examples.

Link to the blog in the comments:

would love to get your feedback and thoughts.

Thank you
