trigger-dev-playground

An agentic workflow playground built with Trigger.dev, OpenAI, and Jina AI. This project demonstrates an LLM-powered workflow with chain-of-thought reasoning and web search/reading capabilities.

Overview

This repository contains a Trigger.dev workflow that:

• Uses OpenAI GPT-4.1-mini for natural language understanding and reasoning
• Leverages Jina AI for web search (/s/jina.ai) and web reading (/r/jina.ai)
• Implements a Chain-of-Thought + Reflexion prompting pattern for structured reasoning
• Employs OpenAI's tool calling (function calling) for integrated web search and reading

Project Structure

src/trigger/
  example.ts           # Main workflow task (company-finder)
  procedures/
    jina.ts            # Jina AI search and reader integrations
  data/
    index.ts           # Chain-of-Thought Reflexion prompt template
trigger.config.ts     # Trigger.dev configuration

Workflow: company-finder

The main workflow (sendUserEmailWorkflow) accepts a query and:

1. Initializes an LLM with a Chain-of-Thought + Reflexion system prompt
2. Provides two tools:
   • web-search: Search the web via Jina AI
   • web-reader: Read web page content via Jina AI
3. Loops until the model produces a <<Final Response>> tag
4. Returns the complete conversation with reasoning

Setup

Prerequisites

• Node.js 18+
• npm or pnpm
• OpenAI API key
• Jina AI API key

Installation

npm install

Environment Variables

Create a .env file with:

OPENAI_API_KEY=sk-...

Configuration

Update trigger.config.ts with your Trigger.dev project ID:

export default defineConfig({
  project: "your-project-id",
  maxDuration: timeout.None,
});

Usage

Deploy and run via Trigger.dev dashboard, or use the Trigger.dev CLI:
