I want to install the "yq" skill in my project. Please run this command in my terminal: # Install skill into your project (2 files) mkdir -p .claude/skills/yq && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/yq/SKILL.md "https://raw.githubusercontent.com/majiayu000/claude-skill-registry/main/skills/data/yq/SKILL.md" && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/yq/metadata.json "https://raw.githubusercontent.com/majiayu000/claude-skill-registry/main/skills/data/yq/metadata.json" Then restart Claude Code (or reload the window in Cursor) so the skill is picked up.
