Codex
OpenAI’s coding agent/CLI—useful for parallel tasks and repo edits with clear specs.
Documentation-backed
Conclusion
Reach for Codex when you have a written task boundary and want a coding agent that can execute against the repository with explicit checks.
Prerequisites
- Access to the current Codex CLI or documented coding agent surface
- A repository with a runnable verify step
Steps
- Confirm install and auth against the official Codex docs (linked in sources).
- Write a short task brief: goal, files in scope, out-of-scope, and verify command.
- Run the agent on one task at a time; clear context between unrelated tasks.
- Review the diff before merge—especially dependency, auth, and deploy files.
Template fields
- Task goal:
- In scope / out of scope:
- Verify command:
Definition of done
A scoped task produces a reviewable diff that passes your verify command.
Anti-patterns
- Multiple unrelated goals in one session
- Accepting dependency changes without reading the lockfile diff
