Research US legal regulations with CourtListener, LegiScan, OpenRouter and web search

Who is this for

This workflow is designed for legal professionals, policy analysts, and compliance teams who need to:

• Research case law, legislation, and regulatory developments on specific topics
• Build comprehensive legal intelligence reports from authoritative sources
• Track enforcement trends and regulatory patterns
• Support litigation strategy with thorough background research

It's ideal for animal law attorneys, advocacy organizations tracking animal welfare legislation, policy teams monitoring ag-gag laws and farm animal protection bills, and researchers building legal cases against animal cruelty.

What it does

This specialized legal research agent conducts comprehensive US legal and regulatory research:

1. Discovery phase: Casts a wide net across legal databases

• CourtListener for federal and state court opinions and dockets
• LegiScan for legislation across all 50 states
• DocumentCloud for government enforcement documents
• Serper for legal analysis, news, and academic papers

1. Prioritization phase: AI evaluates all discovered items and selects the most relevant (3-10 items) with scoring rationale
2. Retrieval phase: Fetches complete text of prioritized court opinions, bill text, and documents
3. Analysis phase: Synthesizes patterns, contradictions, and strategic insights
4. Verification phase: Validates factual claims against source documents with hallucination detection

The verification phase uses a specialized legal-focused prompt that distinguishes between legitimate legal strategy (which should never be flagged) and actual factual errors like wrong case citations or non-existent statutes.
