Agentic Code Generation with OpenAI Codex CLI — A Knight's Tour Walkthrough

OpenAI Codex CLI is used in staged prompts to build a Knight’s Tour project from scratch.

The workflow starts with a command-line solver, then adds pytest coverage and terminal styling.

It finishes by extending the project into a Flask-based browser visualization.

The piece highlights a practical agentic coding pattern: scaffold, test, and expand software with prompts.
