🌟 Essential Skill: skill-creator
⭐ 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.
Why This skill-creator?
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 structural validator plus provenance-checked old-vs-new capability audit; packaging re-verifies the completed review instead of trusting a marker |
| 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 |
| Distill past conversations safely | Not covered | Explicit local manifest, message-level time window, redaction, opaque source IDs, ignored .enrich/ staging, and manual promotion into references/scripts |
| Ground knowledge skills in evidence | General advice | Authority ladder from real calls and machine-readable specs through production code, plus executable-example smoke checks and evidence-boundary rules |
| Have both installed at once | Coin flip — the two descriptions are near-identical | Detects the clash on trigger and offers a one-command, reversible SessionStart routing hook (only ever installed when both coexist); the official plugin stays usable by explicit request |
| Your own skill collides with an installed plugin | Not covered | generate_supersede_kit.py stamps the same conditional routing kit into your skill, plus a measured precedence decision guide (rename → description tiebreaker → hook → disable) |
