Skill Builder

aiskillstore/marketplace-skill-builder

Create new Claude Code Skills with proper YAML frontmatter, progressive disclosure structure, and complete directory organization. Use when you need to build custom skills for specific workflows, generate skill templates, or understand the Claude Skills specification.

This is a copy. The original lives at comeonoliver/skillshub-skill-builder.

Install

one command, takes just this skill from the repository 
npx skills add https://github.com/aiskillstore/marketplace --skill skill-builder

How to use it

Copy the folder

Take aiskillstore/marketplace-skill-builder from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm. Without those the skill loads but fails at the first command.
