I ve been using Codex, Claude Code, and OpenClaw for different kinds of work:

• Codex (now @ChatGPT by OpenAI )is strong at long-context planning and execution.

• @Claude Code acts like a supervisor and a second pair of eyes.

• @OpenClaw is like my daily operations intern.

I know there are many other agent harnesses. Many are open-source, including OpenHands, @Pi Coding Agent , and Hermes.
