      summary: Get Locality Schema
      description: 'Get Neo4j graph schema for a locality - enables LLM-generated Cypher queries


        **RECOMMENDED USAGE FOR LLMs:**

        1. Call this endpoint FIRST to get schema

        2. Generate Cypher query based on schema + user question

        3. Submit Cypher via /api/{locality}/query with cypher_query parameter


        **Why Cypher-first approach?**

        - Natural language parsing is limited to predefined patterns

        - Cypher handles arbitrary complexity (multiple filters, aggregations, etc.)

        - LLMs excel at generating Cypher from schema

        - More reliable and maintainable than brittle NL parsing


        This endpoint returns:

        - Node labels and their properties

        - Relationship types and their properties

        - Indexes and constraints (including spatial indexes)

        - Sample Cypher queries

        - Security constraints and best practices
