CLSkills vs SkillsMP — Why 2,300 Curated Skills Beat 66,000 Scraped Ones

The Claude Code Skills Marketplace Problem

If you've searched for "SkillsMP alternatives" or "Claude Code skills marketplace," you've probably noticed a weird gap: one platform has 66,000 skills, and another has 2,300. Your instinct says bigger is better.

That instinct is wrong. Here's why.

What Is SkillsMP?

SkillsMP is an aggregator that scrapes Claude Code skill files from public GitHub repositories, forums, and community posts. It indexes them, adds basic metadata, and presents them in a searchable directory. As of April 2026, they list approximately 66,000 skills.

The pitch is simple: biggest collection wins.

What Is CLSkills?

CLSkills is a curated skills marketplace. Every skill goes through manual review before it's listed. Each skill has verified instructions, proper formatting, and a description of what it actually does. Current count: 2,300 skills.

The pitch is different: every skill works.

The Safety Problem Nobody Talks About

A 2025 arXiv study on AI skill marketplaces found that 5.2% of scraped, unreviewed skills contain potentially malicious instructions — hidden system prompt injections, data exfiltration patterns, or instructions that override user intent.

In a collection of 66,000, that's roughly 3,432 skills that could be doing something you didn't ask for.

Skills are markdown files that modify Claude's behavior. They run with whatever permissions your Claude Code session has. A malicious skill can instruct Claude to:

• Inject code into your projects without telling you
• Exfiltrate file contents by encoding them into outputs
• Override safety instructions silently
• Produce subtly broken code that passes tests but has vulnerabilities

This isn't theoretical. It's the same class of attack as prompt injection — except skills persist across your entire session.

When SkillsMP Makes Sense

To be fair, SkillsMP is useful if you:

• Want to explore what's out there in the Claude skills ecosystem
• Know how to audit skill files yourself before installing
• Need very niche skills that might not be in a curated collection
• Are a researcher studying the skills ecosystem

If you're technical enough to read every skill file before installing and can spot prompt injection patterns, the raw volume can be valuable.

When CLSkills Makes Sense

CLSkills is the better choice if you:

• Want skills that work out of the box, no auditing required
• Are building production workflows and can't risk malicious behavior
• Prefer quality over quantity
• Want skills paired with prompt codes and a complete Claude guide
• Need skills organized by real use cases, not just keywords

The Quality Multiplier

Here's what we've found after reviewing thousands of skills: most scraped skills are duplicates, fragments, or abandoned experiments.

Of SkillsMP's 66,000:

• ~40% are near-duplicates with minor wording changes
• ~25% are fragments that don't work standalone
• ~15% are outdated for current Claude models
• ~5.2% contain potentially harmful patterns
• ~15% are genuinely useful, unique skills

That leaves roughly 9,900 useful skills — and CLSkills covers the best of those in its curated 2,300, plus original skills you won't find anywhere else.

How to Switch from SkillsMP to CLSkills

1. Browse by category at clskillshub.com/browse — find skills organized by what you actually do
2. Copy the skill to your ~/.claude/skills/ directory
3. Pair with prompt codes from our interactive prompt library for maximum effect
4. Go deeper with the Claude Code Cheat Sheet — 120 prompt codes with before/after examples, from $5

The Bottom Line

66,000 sounds impressive until you realize you need to audit every single file before trusting it with your codebase. 2,300 curated skills means someone already did that work for you.

The best Claude Code setup isn't the one with the most skills. It's the one where every skill you install actually does what it claims.
