Add SkillHub to Directories (Universal AI Agent Skills Package Manager)

Start with the repository README and its Directories section, then review the readme-hygiene check that blocked PR #354. Done means adding the proposed SkillHub entry after maintainer review while preserving the existing directory format and passing the README hygiene check.

Request: Add SkillHub to Directories section

What is SkillHub?

SkillHub is an open-source universal package manager and registry for AI coding agent skills — essentially "NPM for AI coding agents."

Repo: https://github.com/Blazkojj/skillhub

Why add it to the Directories section?

Currently, developers manually copy-paste .cursorrules and .mdc files between projects. SkillHub automates this entire workflow:

• 630+ verified skills across 9 categories (Frontend, Backend, Database, DevOps, Security, Testing, Architecture, AI/LLM, Mobile)
• 15 supported agent targets: Claude Code, OpenCode, Cursor, Windsurf, RooCode, GitHub Copilot, Continue.dev, Codeium, Aider, Zed, Void, Tabnine, Gemini, Kilo Code, Universal
• Interactive split-pane TUI with live preview, category tabs, instant search filter
• 9-rule security scanner detecting prompt injections, RCE, leaked API keys, and exfiltration beacons
• Auto-adaptation engine — transpiles Universal Skill Spec into native formats (.cursor/rules/*.mdc, .claude/skills/*/SKILL.md, etc.)

Installation

git clone https://github.com/Blazkojj/skillhub.git
cd skillhub
npm link
skillhub

Suggested addition to README

## Directories

- [CursorList](https://cursorlist.com)
- [CursorDirectory](https://cursor.directory/)

Context

I initially opened PR #354 to add this directly, but the readme-hygiene check correctly blocked it (contributor-added external listings are maintainer-curated). Opening this Issue instead for maintainer review.

Checklist

• Not a duplicate of any existing entry
• Complements CursorList and CursorDirectory (adds package manager layer)
• Open source (Apache-2.0)
• Actively maintained

Thanks for considering! 🙏
