Explain it to me like I'm new
Codex is a coding agent: it works on real code in a sandboxed environment, proposing and running changes under an approval policy.
Think of it like
A junior engineer who can open the repo — but only merges what you approve.
What actually happens
You describe the task. It explores files, edits, runs commands in a sandbox, and returns the result for review.
task → agent → sandbox (read/edit/run) → approval → change
Where I encountered it
Build #017, and my early experiments with agentic coding.

The editions in the Book Stall follow the build where this word first showed up — the mistakes included.
