Quick answer: A safe Codex workflow is inspect → plan → edit → test → review. Keep tasks narrow, protect secrets, and inspect the diff before accepting changes. Check the OpenAI documentation for current product details.
Give the agent useful context
State the desired outcome, relevant files, constraints, test command, and what must not change. Avoid dumping an entire repository when a small context is enough.
Work in small increments
Ask for a plan, implement one slice, and run the project’s tests. Small diffs are easier to review and easier to recover when an assumption is wrong.
Review for security and correctness
- Secrets and credentials
- Authentication and authorization
- Input validation and error paths
- Dependency and migration changes
- Tests that assert the intended behaviour
Build a practice project
