## Overview

Codex is OpenAI’s coding agent for implementation, debugging and review. The CLI explores local projects, plans changes, edits files and invokes installed development tools. IDE integration uses editor context, presents reviewable diffs and supports cloud task delegation. Project instructions, skills and plugins supply guidance and tools; noninteractive execution supports automation. Permissions and task environments determine accessible files and commands.
