SkillCenter releases largest open skill library with 216,938 source-grounded skills for autonomous AI agents

The authors introduce SkillCenter, the largest open skill library for autonomous AI agents, containing 216,938 structured skills across 24 domain bundles. The dataset comprises 114,565 source-grounded skills filtered by a pipeline called SkillGate and 102,373 community skills from GitHub and ClawHub.

• SkillGate filters contributions from peer-reviewed journals, ArXiv, and over 24,000 technical sources to ensure quality.
• Source grounding provides traceability by mapping each retained claim to an exact quotation in its source.
• The framework includes multi-source acquisition, LLM-based quality gating, template-driven generation, and iterative source-grounding.
• All skills are packaged as offline-searchable SQLite FTS5 bundles for agent use.

This library aims to provide grounded operational knowledge to help autonomous agents produce outputs that are correct, secure, and maintainable.
