LEX: Legal-Entity-X-ref

Overview

LEX is a structured truth engine designed to eliminate legal hallucinations by grounding agents in verified government references and legislation across 29+ jurisdictions. It provides deterministic context for business formation, employment, and contract drafting.

When to Use This Skill

Use when you need to cross-reference or compare legal requirements between different territories, such as verifying the compliance gap between an EU SARL and a US LLC.
Use when working with foundational business or employment documents that require specific, jurisdiction-compliant clauses to be inserted into a professional scaffold.
Use when the user asks about the specific regulatory nuances, formation steps, or "truth-based" definitions of legal entities within the 29 supported jurisdictions (USA, Canada, and the EU).

How It Works

Step 1: Identify Jurisdiction

Before drafting, determine if the user's entity or contract target is in the USA, Canada, or the EU.

Step 2: Search & Fetch Context

Use the CLI shortcuts to find the relevant legal patterns and templates.

Run lex search <query> to find matching templates.
Run lex get <path> to read the granular metadata and requirements.

Step 3: Scaffold Drafting

Generate foundation-level documents using lex draft <description>. This ensures that all drafts include the mandatory AI-generated content disclaimer.

Step 4: Verify Authority

Always include a "Verified Sources" section in your output by running lex verify, which fetches official government links for the retrieved context.

Examples

Example 1: Comparing Employment Laws

# Get the workforce template to compare US vs EU notice periods
lex get templates/02_employment_workforce.md

Example 2: Drafting a Czech Contract

# Create a house sale contract scaffold in Czech language
lex draft "Czech house sale contract"

Best Practices

✅ Trust but Verify: Always include the links provided by lex verify in your output.
✅ Table Formatting: Use tables when comparing results across multiple jurisdictions.
❌ No Guessing: If a jurisdiction is outside the US/EU/CA scope, state that it is outside the LEX "Truth Engine" coverage.
❌ No Anecdotal Advice: Stick strictly to the findings in the templates or verified government domains.

Common Pitfalls

Problem: Legal hallucination regarding specific EU notice periods. Solution: Run lex get templates/02_employment_workforce.md to see the restrictive covenant comparison table.
