## Overview

The AI Skills Library is a repository of installable assistant skills, including SAP Fiori design guidance and SAP AI Core operational tools. The main user journey is to select and install a skill with the skills CLI, then use its instructions and references; AI Core skills also provide scripts that query or change AI Core resources. The graph groups the broad design-guidance collections and the operational plugin skills. Script-to-service edges are grounded in sampled calls; the README documents installation, but not the CLI’s internal mechanics.

Main entry points: [`plugins/aicore-skills/README.md`](https://github.com/sap/ai-skills-library/blob/main/plugins/aicore-skills/README.md) (AI Core plugin), [`plugins/aicore-skills/skills/aicore-admin-resources/scripts`](https://github.com/sap/ai-skills-library/tree/main/plugins/aicore-skills/skills/aicore-admin-resources/scripts) (Resource group tools), [`plugins/aicore-skills/skills/aicore-lifecycle-management/scripts`](https://github.com/sap/ai-skills-library/tree/main/plugins/aicore-skills/skills/aicore-lifecycle-management/scripts) (Lifecycle tools), [`plugins/aicore-skills/skills/genai-hub-foundation-models/scripts/list_foundation_models.py`](https://github.com/sap/ai-skills-library/blob/main/plugins/aicore-skills/skills/genai-hub-foundation-models/scripts/list_foundation_models.py) (Foundation models)
