I run Claude Code and Codex side by side. Here's the division of labor that actually works.

Practical comparison of two agentic coding tools with actionable division of labor insights for AI-assisted development workflows.
A developer running Claude Code and Codex side-by-side found a clear division of labor: Claude Code handles exploratory, conversational tasks like design iteration, while Codex in non-interactive mode automates straight-line, repeatable work like version bumps and commit messages. The key enabler is `codex exec`, which runs a single instruction to stdout and can be scripted, with safety rails via `approval_policy` and `sandbox_mode` in `~/.codex/config.toml`. Project conventions live in `AGENTS.md`, and medium reasoning effort on GPT-5.5 keeps routine automation fast and cheap.
