Codex

OpenAI's coding agent.

OpenAI's cloud-side coding agent. Strong on long-horizon refactors and back-end work; pairs well with Claude Code for cross-checking on ambitious projects.

  • Cloud-hosted parallel agents
  • GitHub-native PR loops
  • Useful second opinion on architecture-level work
Why

Codex runs in the cloud while Claude Code runs on your machine — different shapes, complementary strengths. Pairing both catches blind spots a single-agent setup misses.

How
  • Codex for long-horizon refactors and PR-shaped work
  • Claude Code locally for surgical edits + tool use
  • Architectural decisions cross-checked between both

FAQ
How does Codex compare to Claude Code?
Both are terminal-native coding agents. Codex tilts toward focused diff generation; Claude Code tilts toward full repo orchestration with skills, hooks, and subagents. I run both, and route per task.
Can I use Codex with my own repo conventions?
Yes — give it a CLAUDE.md / AGENTS.md / similar onboarding doc and it follows the conventions. The smaller your context budget, the more important that doc becomes.
Does Codex auto-merge to main?
Never in my setups. Codex proposes the diff, the human approves and commits. Trust grows over time, but the merge button stays human.
In production
  • Legacy migration sprint

    Codex paired with Claude Code for a v1 → v2 migration on a fleet site — 4 days from start to merge.

  • Diff-grade refactors

    Codex tuned for focused diffs — best lane is single-concern refactors with tight test coverage.

  • Human-approved commits

    Codex proposes, human approves; never an auto-merge. Trust grows over runs, the merge button stays human.
