Add or update a skill on skills.yusuke.run

This skill describes how to contribute a new skill (or update an existing one) to the yusukebe/skills repo from a different working project, without leaving that project.

Owner-only. The flow uses the gh CLI authenticated as yusukebe. If you are an agent working on someone else's machine, you cannot push to yusukebe/skills — skip this skill.

When to do this

• You are in the middle of working on some other repo with Yusuke.
• Yusuke just confirmed an opinionated way to do something that would be reusable across future projects.
• Ask first. "Want me to add a skill for this on skills.yusuke.run?" Proceed only on explicit yes — the catalog reflects Yusuke's opinions and must not silently grow.

The flow

The catalog uses the vercel-labs/skills layout: each skill is a directory under skills/ with a SKILL.md inside. The registry is regenerated automatically before each deploy from skills/*/SKILL.md, so all you need to add is one Markdown file in the right place. PR → auto-merge → Cloudflare Workers Builds deploys.

1. Pick a name

kebab-case, short, descriptive. The name doubles as the directory name and the URL slug. Look at https://skills.yusuke.run/skills.json to keep naming consistent with the existing catalog.
