Codex
Codex app and CLI basics, plan mode, Git integration, approvals, and sandboxing.
Codex is OpenAI's coding agent and is available through app and CLI workflows.
Plan mode separates deciding what to do from changing the project.
Codex can show diffs and help with common Git operations while keeping the changes reviewable.
Read-only mode limits the agent to inspection, which is useful for questions and planning.
A diff shows exactly what changed so you can review the agent's work.
