What this workflow does
This AI workflow has 29 nodes and runs on a schedule (every 15 minutes). Along the way it connects OpenAI Chat Model and Slack.
How it runs
Trigger: On a schedule (every 15 minutes).
- Workflow Configuration (Edit Fields (Set)): sets 7 fields: criticalSlackChannel, highPrioritySlackChannel, escalationEmail…
- Generate Sample Events (Code): runs custom JavaScript code
- Signal Prioritization Agent (AI Agent): runs an AI agent, with model: OpenAI Model - Prioritization Agent; 1 tool (Enrichment Agent Tool); output parser: Structured Output - Prioritization
- Delivery Orchestration Agent (AI Agent): runs an AI agent, with model: OpenAI Model - Delivery Agent; 2 tools (Email Tool, Slack Tool); output parser: Structured Output - Delivery
- Route by Priority (Switch): routes items into 4 branches
- Check Escalation Required (If): checks a condition and branches into true / false
- Store Critical Events (Data table): uses Data table
- Store High Priority Events (Data table): uses Data table
- Store Medium Priority Events (Data table): uses Data table
- Store Low Priority Events (Data table): uses Data table
…plus 7 more steps. See the full node list below.
