skill-maintainer

Create, update, improve, test, rename or remove an agent skill so it works in both Claude Code and Codex (and other agents) from one copy, with a Codex agents/openai.yaml and a .claude/skills symlink. Use when asked to add or write a skill or SKILL.md, turn a workflow into a skill, fix, change or improve an existing skill, test a skill or tune its description so it triggers, set up agents/openai.yaml, make a Claude skill available to Codex or the reverse, or check a repository's skills.
