Agent Skill Index

Agent Skill Index is a catalog system that enables AI agents to dynamically load modular instruction sets (SKILL.md files) for specific tasks, reducing prompt overhead while maintaining portability across different AI platforms like Claude, GitHub Copilot, and VS Code. Skills are discovered through marketplaces like SkillsMP or managed via CLI tools like npx skills, allowing agents to load only necessary capabilities on-demand through a three-stage process: browsing available skills, loading relevant instructions, and executing with helper files. This architecture eliminates bloated prompts and enables reusable, verifiable task instructions across heterogeneous AI tools and models.
