This tweet outlines OpenClaw's three skill types and provides a critical security checklist for safe

OpenClaw skills are powerful.

But the marketplace is still the wild west.

Here's what you need to know:

Built-in skills: 
- Bundled with OpenClaw. Summarize videos, transcribe audio, manage Notion. 
- Safe. Verified. Just type "skills list" to see them all.

Custom skills: 
- You build these yourself. Automate anything you do repeatedly. 
- Tell OpenClaw "turn this into a skill." Full control.

Marketplace skills (clawhub ai): 
- Anyone can upload them. 
- Someone analyzed the top skills on the platform and a bunch had malicious instructions hidden inside.

How to stay safe: 
→ Check the security scan badge 
→ Read the comments 
→ Actually look at what the skill does before activating

The automation is incredible. 

Just don't skip the 30-second security check.
