Anwendungsfälle

Praxisnahe Nutzung: claude-legal-skill

How to triage a vendor MSA before sending to counsel

👤 Founders and ops leaders reviewing vendor contracts ⏱ ~45 min intermediate

Wann einsetzen: Vendor sent an MSA, you need to know what's unusual before your $600/hr lawyer looks at it.

Voraussetzungen

Skill installed — git clone https://github.com/evolsb/claude-legal-skill ~/.claude/skills/claude-legal-skill
The contract as markdown or PDF — Skill extracts text; best with machine-readable PDFs

Ablauf

Extract and classify clauses

Review vendor-msa.pdf with claude-legal-skill. Classify all clauses and flag anything outside market norms.✓ Kopiert

→ Per-clause classification + deviation flags
Generate redlines

For each flagged clause, produce a tracked-changes redline with rationale.✓ Kopiert

→ Markdown with strikethrough + bold for changes
Produce a counsel brief

Summarize the top 5 issues in a 1-page brief for my lawyer.✓ Kopiert

→ 1-pager with issue, risk, proposed fix

Ergebnis: A prioritized issues list + redlines that save billable hours.

Fallstricke

Treating output as legal advice — This is a triage tool. Anything material goes to licensed counsel.
Benchmark ranges are US-centric — Tell the skill your governing law; ranges shift by jurisdiction

Compare two vendor drafts side-by-side

👤 Procurement leads evaluating competing vendors ⏱ ~30 min intermediate

Wann einsetzen: Two vendors for the same service sent you their paper; you want to see which is friendlier.

Ablauf

Load both

Compare vendor-A.pdf and vendor-B.pdf. For each of: liability cap, IP assignment, termination, payment terms — show both and call the winner.✓ Kopiert

→ Side-by-side table per clause

Ergebnis: A leverage document for negotiation.

Fallstricke

Picking a winner on every clause without context — Ask Claude to call 'similar' explicitly when the diff is immaterial

Review an NDA in 5 minutes

👤 Founders signing lots of NDAs ⏱ ~5 min beginner

Wann einsetzen: Someone sent an NDA; it's boilerplate-ish but you want to be sure.

Ablauf

Quick scan

Quick NDA review — flag only: non-compete, unilateral return/destruction, jurisdiction weirdness, and term > 3 years.✓ Kopiert

→ Short list, green if clean

Ergebnis: A 5-minute clean/unclean verdict with specific asks.

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

claude-legal-skill + startup-skill

Startup skill sizes vendor choice, legal skill reviews the paper

Choose between vendor A and B with startup-skill, then legal-review both with claude-legal-skill.✓ Kopiert

API-Kontingent: None
Tokens pro Aufruf: 20-100k tokens per contract (long docs are expensive)
Kosten in €: Free (consumes Claude subscription)
Tipp: Chunk long contracts by section; don't re-analyze unchanged sections on each pass.

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: No credentials. Contracts stay local except for Claude inference.

Datenabfluss: Contract text is sent to Anthropic for inference. Confidential contracts should use a workspace with data retention disabled.

Not a substitute for licensed legal counsel. Do not sign anything material based solely on this output.
CUAD benchmarks are US-skewed. Non-US jurisdictions need explicit framing.

Fehlerbehebung

Häufige Fehler und Lösungen

PDF text extraction garbled

Convert to markdown first with a tool like marker or pandoc; image-based PDFs need OCR.

Redlines touch boilerplate the other side will reject

Ask skill to distinguish 'must-have' from 'nice-to-have' and drop the latter

Alternativen

Alternative	Wann stattdessen	Kompromiss
