The `skills` CLI (https://github.com/openclaw/skills) requires a YAML
frontmatter block with `name` and `description` to recognize a SKILL.md
as a valid skill. The current file declares description as a Markdown
blockquote, which causes:
$ npx skills add jackwener/wx-cli -g
No valid skills found. Skills require a SKILL.md with name and description.
Switching to standard frontmatter makes installation work end-to-end.
Verified with `npx skills add . -l`:
Found 1 skill
wx-cli
