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

Description

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

Webhook Trigger
Accepts contract uploads via API endpoint.

Workflow Configuration
Defines:
Risk threshold
Alert recipients
Slack notification channel

PDF Text Extraction
Extracts raw text from uploaded contract files.

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

Structured Output Parsing
Ensures consistent JSON outputs for all agents

Data Aggregation
Merges outputs from all AI agents into one dataset

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

Data Preparation
Formats contract data for storage and tracking

Database Storage
Stores:
Contract metadata
Clauses
Obligations
Risk scoring results

Risk Evaluation
Compares calculated risk score against threshold

Alert System
If risk is high:
Sends email alerts
Sends Slack notifications
