Professional Claude Code skills marketplace featuring 53 production-ready skills for enhanced development workflows.
⭐ Start here if you want to create your own skills!
The skill-creator is the meta-skill that enables you to build, validate, and package your own Claude Code skills. It's the most important tool in this marketplace because it empowers you to extend Claude Code with your own specialized workflows.
This is a production-hardened fork of Anthropic's official skill-creator, born from building real skills and hitting every wall the official version doesn't warn you about.
The official skill-creator tells you what to build. Ours also tells you what not to try — and why.
| You're trying to... | Official | This Fork |
|---|---|---|
| Research before building | "Check available MCPs" (5 lines) | 8-channel search protocol with decision matrix: Adopt / Extend / Build |
| Create a skill interactively | Prose-based instructions | 9 structured AskUserQuestion checkpoints — user never loses context |
| Avoid common mistakes | No guidance | Cache edit warnings, prerequisite checks, security scan gate |
| Know the architecture options | Not mentioned | Inline vs Fork decision guide with examples (choosing wrong silently breaks your skill) |
| Validate before shipping | Basic YAML check | Expanded validator (all frontmatter fields, path reference integrity, whitespace issues) |
| Catch security issues | No tooling | security_scan.py with gitleaks integration — hard gate before packaging |
| Learn from real failures | No failure cases | Battle-tested methodology with documented failure patterns and gotchas |
Quality comparison (independent audit, 8 dimensions):
| Dimension | Official | This Fork |
|---|---|---|
| Actionability | 7 | 9 |
| Error Prevention | 5 | 9 |
| Prior Art Research | 4 | 9 |
| Counter Review Process | 4 | 8 |
| Real-World Lessons | 3 | 8 |
