Skills Toolkit for Claude Code
A plugin for creating and managing Claude Code skills and plugins.
About skill-composer vs Claude's skill-creator
This toolkit includes skill-composer, which differs significantly from Claude's built-in skill-creator:
| Aspect | skill-composer | Claude's skill-creator |
|---|
| Philosophy | Convention enforcement upfront | Evaluation-driven iteration |
| Approach | Opinionated, enforced best practices from start | Learn via test feedback loops |
| Interviews | Multi-stage requirements gathering (purpose, scope, complexity, tools) | Minimal upfront requirements |
| Best Practices | Enforces from the start (frontmatter, 80% rule, references, token efficiency) | Discovered through empirical testing |
| Workflow | Design → Structure → Build → [Optional: Refine → Test] | Build → Test → Improve based on results |
| Output | Fully structured skill (SKILL.md, references/, scripts/ as needed) | Working skill you iterate on |
| Use When | Building skills with conventions you want enforced consistently | Building skills you'll test and improve empirically |
| Ecosystem | Part of full toolkit (refiner, tester, plugin-creator) | Standalone, integrates with evaluation |
TL;DR: skill-composer enforces conventions upfront. Claude's skill-creator improves via evaluation loops.
Use skill-composer if:
- You want conventions enforced from the ground up
- You're building consistent, production-ready skills
- You value structured SKILL.md, references, and tool scoping upfront
- You want to avoid common skill-building mistakes by design
Use Claude's skill-creator if:
- You want to build and improve skills through empirical testing
- You prefer iterative refinement based on evaluation results
- You're comfortable discovering best practices via feedback loops
- You want to measure skill effectiveness with benchmarks
