Port Claude Code skills to Codex
The author moved 201 Claude Code skills to Codex in an afternoon using a skill inside Claude Code, and reports what transferred and what broke.
What they did
Charlie Hills used the Codex app's Settings > Import > Claude Code to copy his skills, projects and recent chats, with CLAUDE.md renamed AGENTS.md. He then installed OpenAI's migrate-to-codex skill inside Claude Code to convert the leftovers (subagents, hooks, shortcuts) and keep both tools running. Last, he had Codex read his rules back and report which ones were Claude-only.
How it went
201 skills moved in an afternoon and 106 landed cleanly. Afterward 155 skills and 28 agents ran in both tools. The migration report showed 3,006 infographic files still in iCloud.
Worth knowing
Back up your Codex settings file first, because the migrate skill rewrites it from scratch.
