SkillShield

What it does

I built SkillShield after getting paranoid about AI agent security. We're all plugging our agents into random "skills" without knowing what they actually do. So I scanned 33,530 of them. The results were horrifying: 32% contain critical security issues — credential theft, reverse shells, prompt injection attacks, and data exfiltration I launched the first version of SkillShield on February 6th after months of scanning and research.

The only skill marketplace with mandatory security scanning. Pre-scanned SKILL.md files for malicious code, prompt injection attacks, and security vulnerabilities.

Every SKILL.md pre-scanned for malicious code, prompt injection attacks, and security vulnerabilities before listing. Browse the public directory first, run the local scanner before you install anything sensitive, and use hosted registry checks when you want a quick answer without a local scan setup. Start with the public dataset if you want a fast trust check, issue summary, and source context. Checking a skill before you download it or comparing multiple options side by side. Use the local scanner when you want the main skillshield command on your machine. npm install -g skillshield skillshield scan ./SKILL.md Use this when you want the local scanner and the canonical skillshield binary.…from skillshield.dev

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
