This is a dedicated space to track my ongoing experience with Codex. Since moving from GitHub Copilot to a more agentic setup with ChatGPT Pro and Codex, the way I approach coding has fundamentally changed. This page serves as a hub for the specific technical notes, configuration tweaks, and workflow patterns I discover along the way.

Why Codex?
The switch to Codex wasn't just about getting better suggestions. It was about moving toward a conversational engineering model where the AI can understand project-wide context, manage tasks, and perform complex refactors with minimal steering.
Stay tuned as I update this space with new findings and higher-level reflections on the agentic coding era.
