Codex

OpenAI’s coding agent/CLI—useful for parallel tasks and repo edits with clear specs.

Documentation-backed · Applicable: OpenAI Codex CLI/agent; confirm current product name and version before following steps

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

  1. Confirm install and auth against the official Codex docs (linked in sources).
  2. Write a short task brief: goal, files in scope, out-of-scope, and verify command.
  3. Run the agent on one task at a time; clear context between unrelated tasks.
  4. 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
