winmetta/agent-skills
Agent skills from Win Metta that work in both Claude Code and Codex, starting with skill-maintainer for creating and checking shared skills.
Write or update a pull request or merge request title and description, on any hosting platform, with the sections Why?, Impact, Technical Impact, Changelog (Conventional Commits), What changed, Validation, Dev Test, References, Not included / follow-ups and Checklist. Use when asked to open a PR or MR, write, draft or update its description, or when a branch's scope changed and its PR text no longer matches.
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.
