Agent Skills are specialized instruction packages that AI assistants can load on demand to perform specific tasks more effectively. Developed by Anthropic and now an open industry standard, these skills provide three key benefits: modularization of agent prompts, interoperability across different AI platforms, and specialized domain expertise. Users can install pre-defined skills from marketplaces like SkillHub and SkillsMP or create custom skills using SKILL.md files. However, security research has identified vulnerabilities in 26.1% of skills, including prompt injection and data exfiltration risks. Best practices include verifying package names and auditing skills before installation. The ecosystem continues to grow with enhanced security frameworks and industry-specific skill collections expected in the future.
