difyctl skills

Agent skills for the difyctl CLI. They use the standard Agent Skills layout: one folder per skill, each with a SKILL.md. There is no index to maintain.

difyctl install skills <dir> downloads them from GitHub at install time, from the commit that difyctl was built from. --from points at any GitHub folder with the same layout, or at a local folder. The same files install through the Vercel installer: npx skills add langgenius/dify --skill difyctl -g.

Adding a skill

One folder per skill: difyctl is the base skill, scenario skills are difyctl-<scenario>.
SKILL.md frontmatter has name (equal to the folder name: lowercase letters, digits, dashes) and description. The description says when to use the skill; the base skill quotes it.
Any files may sit beside SKILL.md: references/, scripts/, assets/. Commit scripts as executable (chmod +x); the installer keeps the bit.
A scenario skill opens with: Read ../difyctl/SKILL.md first.
Every difyctl <command> named in backticks must exist in the command tree. Every dotted op id must exist in cli/test/fixtures/catalog.json.
List every scenario skill in the base skill's "Other skills" section.

A change here reaches users with the next difyctl build. Anyone can get it sooner with --from https://github.com/langgenius/dify/tree/main/skills.
