About Codex

Codex is OpenAI’s coding agent for working on software projects. It can use project context to help implement changes, investigate problems, and check its work across coding workflows. Official guidance covers the CLI, IDE extension, and desktop experience. Give it a concrete outcome, the relevant project context, and a way to verify the result. For example, define the expected behavior of a signup flow and the checks that should pass. Review the resulting changes and choose permissions that fit the task.

Work in project context

Provide the relevant repository, files, and constraints so the agent can work on a specific change.

Implement and validate

Ask for a behavior change together with checks that show whether the result works.

Review the changes

Inspect the diff and evidence before accepting work or publishing a release.

Build, then get discovered
