ccode-to-codex
Migrate Claude Code skills and Agents to Open AI Codex native skills and agents. Semantic mapping preserves original behavior, classifies migration risk (MECHANICAL / MANUAL / REFACTOR), validates structure, and tracks progress end-to-end. No manual rewrite required. Keep what you built. Run it in Codex CLI. Experimental.
