Workflows (Codex)

Development usage patterns with Codex

This page gives end-to-end workflow examples for the Codex IDE extension, the Codex CLI, and Codex cloud.

Codex works best when you treat it like a teammate with explicit context and a clear definition of “done.”

Each workflow includes:

When to use it and which Codex surface fits best (IDE, CLI, or cloud).

Steps with example user prompts.

Context notes: what Codex automatically sees vs what you should attach.

Verification: how to check the output.

If you are new to Codex, read Prompting first, then come back here for concrete recipes.
