# SkillCenter: A Large-Scale Source-Grounded Skill Library for Autonomous AI Agents

## AI commentary

> This paper is a treasure trove for AI agent developers—it distills structured, traceable knowledge packets from vast literature and marketplace skills, directly lowering the engineering cost of building reliable agents. The source-grounding mechanism deserves special attention, as it offers a concrete path to mitigate agent hallucinations and reuse issues. I recommend it to any team working on agent toolchains, RAG, or explainable AI.

## At a glance

This paper presents SkillCenter, claimed to be the largest open skill library for autonomous agents, comprising 216,938 structured skills across 24 domain bundles. A SkillGate-filtered pipeline contributes 114,565 source-grounded skills from peer-reviewed journals, ArXiv, and over 24,000 technical sources, integrated with 102,373 community skills from GitHub and the ClawHub marketplace. Each skill includes traceable citations to exact quotes in its source, shipped as offline-searchable SQLite FTS5 bundles, providing verifiable and maintainable operational knowledge for autonomous AI agents.

## Key points

- SkillCenter contains 216,938 skills across 24 domain bundles, making it the largest open skill library for agents.
- 114,565 source-grounded skills are acquired through a SkillGate quality-filtered pipeline from academic and technical sources.
- 102,373 community skills from GitHub and ClawHub marketplace are integrated for complementary coverage.
- All skills offer source traceability (exact citations) and are shipped as offline-searchable SQLite FTS5 bundles.

## Full text

Autonomous AI agents can execute complex tasks with limited human review, yet they often lack the grounded operational knowledge to make their outputs not just executable but correct, secure, and maintainable. We introduce SkillCenter, to our knowledge the largest open skill library for agents by total count: 216,938 structured skills across 24 domain bundles. A SkillGate-filtered pipeline contributes 114,565 source-grounded skills from peer-reviewed journals, ArXiv, and over 24,000 technical sources, integrated with 102,373 community skills from GitHub and the ClawHub marketplace. We present the end-to-end framework that builds the pipeline subset: multi-source acquisition, an LLM-based quality gate (SkillGate), template-driven generation, iterative source-grounding, and quality-controlled publishing. Source grounding is a traceability guarantee: each retained claim maps to an exact quotation in its source. All skills ship as offline-searchable SQLite FTS5 bundles.
