Overview

Understanding the lifecycle of a Julep task is crucial for building effective workflows. Let’s explore this through the lens of a Trip Plan task - a practical example that showcases key aspects of task execution. The Trip Plan task is an ideal example because it demonstrates:
  1. Parallel execution of workflow steps
  2. Integration with multiple external APIs:
  3. Data aggregation from various sources
  4. AI-powered personalization of results
Below is a visual representation of how this task flows through Julep’s execution lifecycle:

Lifecycle of the Trip Plan Task

Let’s examine each phase of the execution lifecycle using this task as our guide.
This is a simplified representation of the execution lifecycle. In practice, Julep handles many more details and edge cases to ensure robust and efficient task execution.
Out here in this section, we will be focusing on the main workflow steps of the Trip Plan task and how these steps are executed in Julep.

​
1. Input Schema

First, we define what inputs our task expects: 

input_schema:
    type: object
    properties:
        locations:
            type: array
            items:
                type: string
This schema specifies that our task expects an array of location strings (e.g., ["New York", "London", "Paris"]).

​
2. Tools Configuration

Next, we define the external tools our task will use: 
- name: weather
  type: integration
  integration:
    provider: weather
    setup:
      openweathermap_api_key: {openweathermap_api_key}

- name: internet_search
  type: integration
  integration:
    provider: brave
    setup:
      brave_api_key: {brave_api_key}
We’re using two integrations:
  • The weather integration to fetch current weather conditions
  • The brave search integration to find tourist attractions

​
3. Main Workflow Steps

​
Step 1: Fetch Weather Data

- over: $ steps[0].input.locations
  map:
    tool: weather
    arguments:
      location: $ _
This step:
  • Iterates over each location in the input array
  • Calls the weather API for each location
  • The _ represents the current location in the iteration

​
Step 2: Search for Tourist Attractions

- over: $ steps[0].input.locations
  map:
    tool: internet_search
    arguments:
      query: $ 'tourist attractions in ' + _
This step:
  • Iterates over the locations again
  • Searches for tourist attractions in each location
  • Constructs a search query by concatenating “tourist attractions in ” with the location

​
Step 3: Combine Data

- evaluate:
    zipped: |-
      $ list(
        zip(
          steps[0].input.locations,
          [output['result'] for output in steps[0].output],
          steps[1].output
        )
      )
This step:
  • Combines the data from previous steps into tuples
  • Each tuple contains: (location, weather_data, attractions_data)
  • Uses Python’s zip function to align the data

​
Step 4: Generate Itineraries

- over: $ _['zipped']
  parallelism: 3
  # Inside the map step, each `_` represents the current element in the list
  # which is a tuple of (location, weather, attractions)
  map:
    prompt:
    - role: system
      content: >-
        $ f'''You are {agent.name}. Your task is to create a detailed itinerary
        for visiting tourist attractions in some locations.
        The user will give you the following information for each location:

        - The location
        - The current weather condition
        - The top tourist attractions'''
    - role: user
      content: >-
        $ f'''Location: {_[0]}
        Weather: {_[1]}
        Attractions: {_[2]}'''
    unwrap: true
This step:
  • Processes up to 3 locations in parallel
  • For each location tuple:
    • Sends a prompt to the AI model
    • Includes location, weather, and attraction data
    • Generates a personalized itinerary

​
Step 5: Format Final Output

- evaluate:
    final_plan: |-
      $ '\\n---------------\\n'.join(activity for activity in _)
This step:
  • Combines all itineraries into a single output
  • Separates each itinerary with a divider

​
Example Output

An example output when running this task with an input of ["New York", "London", "Paris", "Tokyo", "Sydney"]:
Here’s a detailed itinerary for visiting top tourist attractions in New York, considering the current weather conditions.
