Summary
If you're juggling skills between Claude Code and OpenAI's Codex CLI, this handles the conversion grunt work. It parses SKILL.md frontmatter and generates the agents/openai.yaml config Codex expects, runs 17 compatibility checks across both platforms, and builds skills-index.json manifests for registry systems. The cross-platform validator catches the obvious gotchas like missing metadata or broken script paths. It's narrow in scope but solves a real problem if you're maintaining skills for both environments. The conversion isn't perfect out of the box, you'll still need to review the generated instructions and tool definitions, but it beats rewriting everything by hand.
