Codex CLI workflow for local product development

Start in the source-of-truth checkout

Launch Codex from the repository and environment that actually builds the product. Give it the outcome, constraints, and verification commands. Ask for diagnosis before implementation when the cause is uncertain, and keep production writes or external publication outside the task unless explicitly authorized.

Use approvals as a risk boundary

Codex supports sandbox and approval controls. Match them to the task: routine local edits need less ceremony than network access, credential use, destructive commands, or production changes. Always inspect the proposed scope rather than approving a broad capability by habit.

• Preserve dirty work.
• Prefer reversible steps.
• Review commands that cross repository boundaries.
• Run the final checks in the authoritative environment.

Resume with evidence

A useful session record includes the task, repository, branch, changed files, and final check results. CmdBrief keeps that local session metadata and bounded previews visible so you can return to the correct product thread.

Primary sources

Provider terms and product behavior can change. Confirm plan, pricing, model, and permission details in the current official documentation.
