codex-builder
✓Execute implementation plans by delegating to Codex CLI for autonomous code implementation. Use when: (1) User has a plan file generated by Claude Code's plan mode and wants to implement it, (2) User explicitly requests Codex to implement a plan, (3) After plan review is complete and ready for implementation, (4) User provides a path to a plan markdown file and wants automatic implementation. The skill reads the plan file and delegates full implementation to Codex.

SKILL.md
Codex Builder is a specialized tool that takes implementation plans (generated by Claude Code's plan mode or claude-planner skill) and delegates the actual implementation to Codex CLI. When you have a detailed plan and want Codex to autonomously implement it, use this skill.
Codex Builder typically takes 5-20 minutes to complete, depending on plan complexity, number of files, and implementation scope. During execution:
If you interrupt the process thinking it's stuck, you'll lose all progress and may end up with partially-implemented changes.
