LexForge

LexForge is a framework for dynamic law parsing, designed to convert legal documents (such as statutes, directives, or regulations) into a generic, hierarchical data structure. This enables flexible analysis, research, and automation of legal content.

Features

• Dynamic Law Parsing: Parse legal documents into a tree-like structure with customizable levels (e.g., article, section, clause).
• Generic Data Structure: Uses a flexible schema (powered by Zod) to represent any law's hierarchy and content.
• Agent-Based Analysis: Modular agents and tools for analyzing, summarizing, or transforming legal text.
• Extensible: Easily add new agents, tools, or support for additional law formats.

Setup

To run LexForge locally, you will need:

• An Anthropic API key (for agent-based text analysis)
• Node.js + npm installed

Install dependencies:

npm install

Set your API key:

export ANTHROPIC_API_KEY=sk-ant-api03-XXXXXX....

Start the LexForge server:

npm start

(Optional) Run the Inngest dev server for agent and network debugging:

npm run inngest-dev
# or
npx inngest-cli@latest dev -u http://localhost:3000/api/inngest

Usage

• Add Law Files: Place your law documents (e.g., PDFs) in the law_files/ directory.
• Run the Server: The agent(s) will process and analyze the documents, extracting summaries and (with further development) parsing the structure into the generic law tree.
• Access the API: Use the API endpoints to interact with the parsed law data, summaries, or trigger further analysis.

Law Data Structure Example

The core data structure is a flexible tree, where each node can represent any level of a law (e.g., article, section, clause):

{
  levelName: "section",
  identifier: "1",
  content: "This section covers ...",
  children: [
    {
      levelName: "clause",
      identifier: "a",
      content: "Clause text ...",
      children: []
    }
  ]
}

Extending LexForge

• Add new agents in src/agents/ for specialized analysis or extraction tasks.
• Add new tools in src/tools/ to support different document types or processing steps.
• Update the law schema in src/dataStructure.ts to support new law formats or metadata.
