Analyze contract PDFs and score risk with Claude 3.5, Postgres, email and Slack alerts

Overview

This workflow automates end-to-end contract analysis using AI. It extracts clauses, evaluates risks, tracks obligations, and generates an executive summary from uploaded contracts.

By combining multiple AI agents with structured parsing and scoring logic, the workflow provides deep legal insights and automatically flags high-risk contracts. It helps legal, compliance, and business teams review contracts faster, reduce risk, and ensure better decision-making.

How It Works

1. Webhook Trigger

   • Accepts contract uploads via API endpoint.

2. Workflow Configuration

   • Defines:
     • Risk threshold
     • Alert recipients
     • Slack notification channel

3. PDF Text Extraction

   • Extracts raw text from uploaded contract files.

4. Parallel AI Analysis
   Multiple AI agents process the contract simultaneously:

   • Clause Extraction Agent

     • Identifies and categorizes contract clauses

   • Risk Assessment Agent

     • Evaluates clause-level risks
     • Assigns risk levels and recommendations

   • Obligation Extraction Agent

     • Extracts responsibilities, deadlines, and commitments

   • Executive Summary Agent

     • Generates structured contract summary and insights

5. Structured Output Parsing

   • Ensures consistent JSON outputs for all agents

6. Data Aggregation

   • Merges outputs from all AI agents into one dataset

7. Risk Scoring Engine

   • Calculates weighted risk score based on:
     • Clause types
     • Risk levels
     • Missing critical clauses
     • AI confidence scores
   • Generates:
     • Score breakdown
     • Red flags
     • Recommendations

8. Data Preparation

   • Formats contract data for storage and tracking

9. Database Storage

   • Stores:
     • Contract metadata
     • Clauses
     • Obligations
     • Risk scoring results

10. Risk Evaluation

• Compares calculated risk score against threshold

1. Alert System

• If risk is high:
  • Sends email alerts
  • Sends Slack notifications

Setup Instructions

1. Webhook Setup
