What this workflow does
This AI workflow has 22 nodes and runs when an HTTP POST request hits its webhook URL. Along the way it connects Anthropic Chat Model, Postgres, Gmail and Slack.
How it runs
Trigger: When an HTTP POST request hits its webhook URL.
- Workflow Configuration (Edit Fields (Set)): sets 3 fields: riskThreshold, alertRecipients, slackChannel
- Extract PDF Text (Extract from File): extracts data from a file (pdf)
- Clause Extraction Agent (AI Agent): runs an AI agent, with model: Claude 3.5 Model; output parser: Clause Parser
- Risk Assessment Agent (AI Agent): runs an AI agent, with model: Claude 3.5 Model; output parser: Risk Parser
- Obligation Extraction Agent (AI Agent): runs an AI agent, with model: Claude 3.5 Model; output parser: Obligation Parser
- Executive Summary Agent (AI Agent): runs an AI agent, with model: Claude 3.5 Model; output parser: Summary Parser
- Merge: merges the data from its input branches
- Calculate Risk Score (Code): runs custom JavaScript code
- Prepare Contract Data (Edit Fields (Set)): sets 18 fields: contract_id, contract_name, contract_type…
- Insert Contract (Postgres): uses Postgres
…plus 6 more steps. See the full node list below.
