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

Description

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:
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
Prioritization phase: AI evaluates all discovered items and selects the most relevant (3-10 items) with scoring rationale
Retrieval phase: Fetches complete text of prioritized court opinions, bill text, and documents
Analysis phase: Synthesizes patterns, contradictions, and strategic insights
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.
