What this repository is — an open-source legal AI skill library
A legal AI skill is a single Markdown file (SKILL.md) that describes one
applied legal task — «calculate the German court fee under the GKG for a
civil claim», «analyse this case under FRCP Rule 12(b)(6)», «check this DPA
against GDPR Article 28» — in a structured format an AI agent can execute
deterministically.
Skills follow the Anthropic Skills convention: YAML frontmatter (machine-readable contract) + Markdown body (the algorithm). Every skill in this repository is grouped into a plugin by jurisdiction and practice area:
{country}/{practice}/skills/{slug}/SKILL.md
Allowed {country} values: any ISO 3166-1 alpha-2 code, plus general
(jurisdiction-agnostic) and cross-jurisdiction (multi-country comparative).
There are two ways to use these skills:
- Locally. Since this repository is open source and every skill follows the Anthropic Skills/plugin format, you can clone it and use the skills locally (as Claude Code skills/plugins).
- Via the MCP server ThomasMore. Connect any MCP-compatible
client to the MCP server
mcp.thomasmoreai.com; the orchestrator finds and runs the right skill via itsdiscoverandinvoketools. Follow thomasmoreai.com for updates on the MCP server launch.
