Overview

This workflow acts as a System Prompt Optimizer Agent.
You send it a draft prompt or goal, and it returns:

A rewritten optimized system prompt that is clear, specific, and actionable.
A recommendation for the best OpenAI model to use based on reasoning needs, complexity, and latency/cost tradeoffs.

The workflow uses memory for context, so you can iteratively refine prompts.

Forecast property CAPEX and ROI weekly using Google Sheets and GPT-4o

## How It Works This workflow automates weekly capital expenditure (CAPEX) forecasting for property portfolios using a multi-agent AI architecture. It targets property managers, asset managers, and facilities finance teams who need data-driven maintenance budgeting without manual spreadsheet analysis. Three Google Sheets sources, namely: maintenance records, property data, and tenant feedback, are merged into a unified dataset. A Main Prediction Agent orchestrates three specialist sub-agents: a CAPEX Prioritizer that ranks spending needs, an ROI Simulator that models return scenarios, and a Quote Requester that fetches vendor estimates. Each agent is backed by dedicated AI models, memory, and tools including a Calculator and Financial Modeling Tool. Structured predictions are parsed, split by category, formatted, saved back to Google Sheets, and pushed to an external budgeting system via POST, delivering a fully automated, auditable CAPEX planning pipeline every week. ## Setup Steps 1. Connect Google Sheets credentials to all three read nodes and the Save Predictions node. 2. Set correct Sheet IDs for maintenance, property, and tenant feedback tabs. 3. Add Claude or OpenAI API credentials to all Chat Model nodes. 4. Configure the Financial Modeling Tool with your cost rate assumptions. 5. Replace the POST placeholder URL in Update Budgeting System with your actual endpoint. ## Prerequisites - Google Sheets account with populated maintenance, property, and tenant data - Claude or OpenAI API credentials - External budgeting system with a POST-compatible API endpoint ## Use Cases - Weekly CAPEX forecasting for multi-property real estate portfolios - Automated ROI modelling for planned renovations or equipment replacement ## Customization Add more data sources (e.g., IoT sensors, ERP exports). ## Benefits Eliminates manual CAPEX spreadsheet work with autonomous AI forecasting.

Turn support tickets into developer insights with OpenAI, Postgres, Slack and Jira

## Overview This workflow transforms raw support tickets into actionable developer insights using AI and data processing. It automatically detects recurring issues, identifies root causes, ranks severity, and generates a structured engineering report. By combining embeddings, clustering, and AI analysis, it helps teams prioritize bugs, understand user pain points, and take data-driven product decisions. --- ## How It Works 1. **Scheduled Trigger** - Runs automatically at a defined time (e.g., daily). 2. **Workflow Configuration** - Defines time window, similarity threshold, scoring weights, and delivery options. 3. **Fetch Feedback Data** - Retrieves recent support tickets (bugs and feature requests) from Postgres. 4. **Preprocessing** - Cleans, normalizes, and removes duplicate messages. 5. **Embedding & Clustering** - Generates embeddings using OpenAI. - Groups similar tickets using cosine similarity. 6. **Cluster Aggregation** - Combines related tickets into structured clusters. 7. **Root Cause Analysis** - AI agent analyzes clusters to identify: - Root cause - Impacted module - Severity - Debug steps - Fix direction 8. **Severity Scoring** - Calculates weighted score based on: - Frequency - Sentiment - Churn risk - Enterprise impact 9. **Report Generation** - Generates a developer-focused report including: - Executive summary - Ranked bugs - Feature requests - Risk analysis - Sprint priorities 10. **Delivery** - Sends report to Slack - Optionally creates Jira issues - Optional email delivery --- ## Setup Instructions 1. **Database Setup** - Configure Postgres credentials - Ensure `support_tickets` table exists with required fields 2. **OpenAI Configuration** - Add API key for: - Embeddings (text-embedding-3-small) - AI analysis agents 3. **Slack Integration** - Add Slack credentials - Set channel ID 4. **Email Setup (Optional)** - Configure SMTP or email service 5. **Jira Integration (Optional)** - Add Jira credentials - Set project key and issue type 6. **Customize Parameters** - Adjust: - Similarity threshold - Scoring weights - Time window 7. **Schedule Configuration** - Modify trigger timing as needed --- ## Use Cases - Product teams analyzing user feedback at scale - Engineering teams prioritizing bug fixes - SaaS companies tracking churn-related issues - Customer support insights automation - AI-driven product intelligence dashboards --- ## Requirements - OpenAI API key - Postgres database with support ticket data - Slack (optional) - Email service (optional) - Jira account (optional) - n8n instance --- ## Key Features - Automated feedback clustering using embeddings - AI-driven root cause analysis - Weighted severity scoring system - Developer-ready intelligence reports - Multi-channel delivery (Slack, Email, Jira) - Fully customizable scoring and thresholds --- ## Summary A powerful AI-driven workflow that converts raw support tickets into structured developer intelligence. It automates clustering, root cause detection, prioritization, and reporting helping teams fix the right problems faster and build better products.
