# ellmos-ai/skills - Portable Skill Library for LLM Agents
- > Standalone, portable library of AI skills in the Anthropic-compatible `SKILL.md` format. The project is part of the ellmos ecosystem and provides reusable workflow definitions for Claude Code-style agents, Codex-compatible setups, BACH, AGY/Gemini, and other local-first LLM agent runtimes. Tested with 156 passing pytest tests (100% green).

## What this repository contains
- 132 public runtime skills organized into 10 categories (376 tracked skills total).
- The public registry is a minimal discovery index. Internal ownership,
privacy, review, and maintainer fields are kept in a separate No-Push
repository.
- A `SKILL.md` schema with YAML frontmatter for provenance, compatibility, dependencies, and usage.
- A machine-readable catalog index (`registry/components.json`) listing every skill with category, version, description, and supported languages.
- Multilingual documentation across 6 languages (DE, EN, ES, JA, RU, ZH) for humans plus this compact file for crawlers and LLM agents.

This repository is not an MCP server by itself. It is not a hosted SaaS marketplace, prompt pack, or private installer. It is a skill catalog that can be used by MCP-enabled, CLI-based, or local-first agent runtimes that understand `SKILL.md` workflows.
## Public/private boundary
Public skill folders contain only portable methods and neutral assets.
App- or host-specific adapters, accounts, databases, local paths, real user
data, and personal defaults belong in separate private profiles or forks.
`foerderplaner` covers teaching and support planning only; general report
generation lives in the separate public `ellmos-ai/report-forge` project, while
personal support-report templates remain private.
