What this workflow does
This AI workflow has 21 nodes and runs manually, when you click “Execute workflow”. Along the way it connects OpenAI Chat Model, HTTP Request and SerpApi (Google Search).
How it runs
Trigger: Manually, when you click “Execute workflow”.
- Supervisor Agent (AI Agent): runs an AI agent, with model: Supervisor Model; 4 tools (Web Search Tool, Research Content Agent, Strategic Planning Agent, Funding Agency Research Tool); memory: Conversation Memory
- Parse Proposal Structure (Code): runs custom JavaScript code
- Quality Control Agent (AI Agent): runs an AI agent, with model: Quality Control Model; output parser: Quality Assessment Output
- Check Quality Score (If): checks a condition and branches into true / false
- Format Final Proposal (Edit Fields (Set)): sets 4 fields: status, proposal_title, quality_score…
- Flag for Revision (Edit Fields (Set)): sets 4 fields: status, quality_score, weaknesses…
- Prepare Storage Data (Edit Fields (Set)): sets 2 fields: timestamp, proposal_id
- Store Proposal Results (Data table): uses Data table
Services it uses
