Disclaimer

This project is built with the assistance of AI tools (Claude, GPT, Gemini). While every effort is made to ensure accuracy, AI-generated content (skill definitions, reference guides, citations, templates) may contain errors. This is not legal advice. Any output of these skills is a draft for review by a licensed Rechtsanwalt or Syndikusrechtsanwalt under § 43a BRAO and § 2 BORA. Always verify case-law citations independently in Beck-Online, juris, or openjur.net before client-facing or court-facing use. The author accepts no liability. Use at your own risk.

The problem

A [Modellwissen]-Halluzination in einem Kündigungsschreiben ist kein Bug. Sie ist Haftungsexposure unter § 43a Abs. 2 BRAO. Most legal-AI repos are either a clever prompt with no sourcing, or a 100-skill experiment that nobody tested end-to-end. Neither belongs in a Kanzlei.

The fix

A focused, provider-agnostic library: 48 areas, 103 skills, every statute citation linked to its authoritative source, every case-law citation explicitly marked verified or [unverifiziert, prüfen]. A built-in evaluation harness checks every skill against fact patterns. A dated verification log plus the per-plugin verification status show exactly what was checked, when, against which source.

It is not legal advice, not a Beck-Online substitute, and not for Mandatsdaten without a § 203 StGB-compliant gateway. It is a tested drafting aid with an honest paper trail.

Who this is for

What's inside

48 areas: 23 substantive areas of German law (general practice and constitutional/public law), 5 Fachanwaltschaften, 7 EU/cross-cutting compliance frameworks, and 13 additional specialty plugins (regulated industries, IP, professional, finance/antitrust) — together covering the breadth of German legal practice. Each area ships as its own installable plugin.

German legal practice

Fachanwaltschaften

EU / cross-cutting compliance

Substantive general law (expanded coverage)

Regulated industries & cross-cutting (expanded)

Specialty law & IP (expanded)

Each area includes a researcher sub-agent (Quellensuche), drafter sub-agent (Entwurf nach Gutachtenstil), reviewer sub-agent (Risiko- und Berufsrechts-Check), conventions per CONVENTIONS.md, and at least one runnable test under <area>/tests/.

What's different from other German legal-AI repos

How much you can rely on it

We are unsentimental about trust. Here is what is verified today, what is in active improvement, and what is the user's responsibility.

Production-grade today

• Repo structure plus CI. Every plugin manifest validates. CI runs validate.py on every push to catch structural drift. Locally, python scripts/eval.py runs 1,758 fact-pattern assertions across 103 skills (103/103 passing).
• Statute citations. Every § X links to the authoritative public source, gesetze-im-internet.de and EUR-Lex. One click, verifiable.
• Methodology. Gutachtenstil, Anspruchsgrundlagen-Reihenfolge, BGH/Beck-Zitierweise, no Präjudizienbindungs-Argumente, textbook-correct conventions, documented in CONVENTIONS.md and enforced by the reviewer sub-agent.
• Compliance scaffolding. PII redaction (scripts/pii_redact.py), gateway setup guide (references/gateway-setup.md), § 203 / DSGVO / KI-VO checklist (references/compliance-checklist.md).
• Deterministic legal calculators. Fristenberechnung (§§ 187-193 BGB, § 222 ZPO), Verjährung (§§ 195-199 BGB), RVG and GKG fees from version-pinned statutory tables, all stdlib and unit-tested, no model call. See references/rechner.md.
• Citation verification. scripts/verify_citations.py parses every §-anchor, ECLI and CELEX in a skill and resolves it (statute anchors against gesetze-im-internet.de). It runs in CI as an informational pass; --strict (and --online) turns it into a hard gate for local pre-commit use.
• Multi-provider parity. One canonical SKILL.md per skill; the router regenerates Claude / Gemini / OpenAI adapters on demand, no drift.

In active improvement (contributions welcome)

• Case-law verification. Every BAG / BGH / EuGH citation the model could not independently confirm carries [unverifiziert, prüfen]. The verification path is one PR per citation with a Beck-Online / juris / openjur URL. Highest-leverage contribution.
• Legal-accuracy eval. Structural eval ships in CI (does the workflow mention § 1 KSchG). A behavioural layer now generates a promptfoo config from the test.md files (scripts/build_eval_config.py, see evals/README.md): deterministic assertions plus LLM-graded expected_behavior rubrics, judged by a different model family. Growing the per-skill rubric coverage and gold answers is open work.
• Rechtsanwalt review. Each area gets stronger after a 2-hour pass by a licensed Anwalt in that Rechtsgebiet. Reviews are credited per area.

Hard limitations

• No real Mandatsdaten without a § 203-compliant gateway. Anthropic, Google, OpenAI do not sign Verschwiegenheitserklärungen directly for German lawyers. Route through Langdock, deepset Cloud, or comparable before processing privileged data. Setup walkthrough: references/gateway-setup.md.
• Every output is a draft. No skill produces signature-ready text. The Berufspflicht under § 43a Abs. 2 BRAO and § 2 BORA stays with the licensed Anwalt.

Verification path

1. Open the area you need (e.g. arbeitsrecht/)
2. Read the SKILL.md. Identify every [unverifiziert] citation.
3. Verify each in Beck-Online or juris (~30 sec/each). Open a PR removing the marker.
4. Run the skill against an anonymized historical Mandat you already know.
5. Wire a § 203-compliant gateway.
6. Use on live Mandate only after 1 to 5 plus your own Berufsrechts-Freigabe.

The full audit trail lives in VERIFICATION_LOG.md, last pass 2026-05-21.

Documentation

Contribute

The highest-leverage thing you can do is verify one case-law citation. It takes 30 seconds in Beck-Online or juris, and the resulting PR helps every future user.

Also welcome:

• Verified citations, replace [unverifiziert, prüfen] markers with a Beck-Online / juris / openjur URL
• New areas, agrar-, bau-, erbe-, familien-, sozial-, steuer-, verwaltungsrecht; or EU frameworks like eIDAS 2.0, CRA, MiCA. Start by copying arbeitsrecht/ as a template
• Test cases, anonymized fact patterns are the most valuable contribution
• Provider adapters, Mistral, DeepSeek, Llama
• Compliance corrections, § 203, § 43e BRAO, KI-VO, Drittlandtransfer

See CONTRIBUTING.md for the PR workflow.

Live legal data via MCP (NeuRIS)

The repo ships a top-level .mcp.json that enables a single MCP server: rechtsinformationen, a community MIT-licensed wrapper (wolfgangihloff/rechtsinformationen-bund-de-mcp) around the official NeuRIS open API at rechtsinformationen.bund.de, run by DigitalService for the Bundesministerium der Justiz (public beta). It exposes Bundesrecht and federal case-law addressable by ELI/ECLI as JSON/XML/HTML, via tools such as semantische_rechtssuche, deutsche_gesetze_suchen, rechtsprechung_suchen and gesetz_per_eli_abrufen.

This server queries only public statutes and case-law, never Mandatsdaten, so it is § 203-safe. It is preconfigured in .mcp.json but requires a one-time local setup before it will start: the server has no published npm package, so clone the repo, run ./quick-setup.sh (npm install && npm run build), then replace the placeholder absolute path to dist/index.js in .mcp.json with the real one (until then the server simply will not load). For per-area configs and the commercial-database placeholders (Beck-Online, juris, which have no public MCP server yet), see references/mcp-template.json.
