Workflows

Overview

A Workflow is a non-sequential DAG that can be used for complex concurrent scenarios with tasks having multiple inputs.

You can access the final output of the Workflow by using the output attribute.

Context

Workflows have access to the following context variables in addition to the base context:

  • task_outputs: dictionary containing mapping of all task IDs to their outputs.
  • parent_outputs: dictionary containing mapping of parent task IDs to their outputs.
  • parents_output_text: string containing the concatenated outputs of all parent tasks.
  • parents: dictionary containing mapping of parent task IDs to their task objects.
  • children: dictionary containing mapping of child task IDs to their task objects.

Workflow

Let's build a simple workflow. Let's say, we want to write a story in a fantasy world with some unique characters. We could setup a workflow that generates a world based on some keywords. Then we pass the world description to any number of child tasks that create characters. Finally, the last task pulls in information from all parent tasks and writes up a short story.

from griptape.structures import Workflow
from griptape.tasks import PromptTask
from griptape.utils import StructureVisualizer

world_task = PromptTask(
    "Create a fictional world based on the following key words {{ keywords|join(', ') }}",
    context={"keywords": ["fantasy", "ocean", "tidal lock"]},
    id="world",
)


def character_task(task_id: str, character_name: str) -> PromptTask:
    return PromptTask(
        "Based on the following world description create a character named {{ name }}:\n{{ parent_outputs['world'] }}",
        context={"name": character_name},
        id=task_id,
        parent_ids=["world"],
    )


scotty_task = character_task("scotty", "Scotty")
annie_task = character_task("annie", "Annie")

story_task = PromptTask(
    "Based on the following description of the world and characters, write a short story:\n{{ parent_outputs['world'] }}\n{{ parent_outputs['scotty'] }}\n{{ parent_outputs['annie'] }}",
    id="story",
    parent_ids=["world", "scotty", "annie"],
)

workflow = Workflow(tasks=[world_task, story_task, scotty_task, annie_task, story_task])

print(StructureVisualizer(workflow).to_url())

workflow.run()

                             Output: In the vast expanse of the cosmos lies a   
                             unique planet named Thalassara, a world defined by 
                             its eternal dance with the ocean and the stars.    
                             Thalassara is a tidal-locked planet, meaning one   
                             side perpetually faces its sun, Solara, while the  
                             other remains in eternal night. This celestial     
                             configuration has given rise to a world of stark   
                             contrasts and wondrous beauty, where fantasy and

                             The side of Thalassara that faces Solara is known  
                             as the Sunlit Realm. Here, the ocean is a          
                             shimmering expanse of turquoise and azure, teeming 
                             with vibrant marine life. The coastline is dotted  
                             with towering cliffs and lush, verdant forests that
                             thrive under the constant sunlight. The air is warm
                             and filled with the scent of salt and blooming     
                             flowers. The Sunlit Realm is home to the Solari, a

                             like the sun. They are skilled artisans and

                             Encircling the planet is the Twilight Belt, a      
                             narrow region where day and night meet in perpetual
                             dusk. This area is a place of mystery and magic,   
                             where the sky is painted in hues of purple and     
                             orange, and the stars are always visible. The

                             their home. They are the keepers of ancient        
                             knowledge and guardians of the balance between     
                             light and dark.

                             by the glow of bioluminescent flora and fauna. The 
                             ocean here is a deep indigo, and the land is       
                             covered in forests of towering, luminescent trees. 
                             The Nocturnals, a race with skin as dark as the    
                             night and eyes that gleam like stars, inhabit this 
                             region. They are skilled navigators and

                             as the Sunlit Realm. Here, the ocean is a

                             with vibrant marine life. The coastline is dotted

                             like the sun. They are skilled artisans and

                             dusk. This area is a place of mystery and magic,

                             their home. They are the keepers of ancient        
                             knowledge and guardians of the balance between     
                             light and dark.

                             by the glow of bioluminescent flora and fauna. The 
                             ocean here is a deep indigo, and the land is       
                             covered in forests of towering, luminescent trees. 
                             The Nocturnals, a race with skin as dark as the    
                             night and eyes that gleam like stars, inhabit this 
                             region. They are skilled navigators and            
                             astronomers, using the constellations to guide     
                             their way across the darkened seas.

                             empathetic, able to sense the emotions of those    
                             around him, which makes him a compassionate and    
                             understanding friend.

                             As a skilled shadow-weaver, Scotty can manipulate  
                             darkness to create illusions, conceal himself, or

                             energies of the Twilight Belt. Scotty is also a    
                             keeper of ancient knowledge, with a vast           
                             understanding of the history and lore of           
                             Thalassara, which he uses to guide his actions and

                             harmony between the realms of Thalassara. He seeks 
                             to uncover the secrets of the ancient ruins        
                             scattered across the Twilight Belt, believing that 
                             they hold the key to understanding the true nature 
                             of his world. His ultimate goal is to ensure that  
                             the balance between light and dark is preserved,   
                             allowing the beauty and magic of Thalassara to     
                             endure for generations to come.

                             Scotty has a close bond with his fellow            
                             Veilwalkers, particularly his mentor, an elder     
                             named Lirael, who has guided him in honing his     
                             shadow-weaving abilities. He also shares a deep    
                             friendship with a Nocturnal astronomer named Kael, 
                             with whom he often exchanges knowledge and insights
                             about the stars and the night sky. Though he is    
                             more reserved with the Solari, Scotty respects     
                             their artistry and occasionally collaborates with  
                             them on projects that blend light and shadow.      

                             **Quirks:**                                        
                             Scotty has a habit of speaking in metaphors, often 
                             drawing on the imagery of the twilight and the     
                             stars to convey his thoughts. He also carries a    
                             small, intricately carved obsidian pendant, a      
                             family heirloom that he believes connects him to   
                             the spirits of his ancestors. When deep in thought,
                             he can often be found tracing the patterns of the  
                             constellations with his fingers, a gesture that    
                             calms and centers him.

                             as the Sunlit Realm. Here, the ocean is a          
                             shimmering expanse of turquoise and azure, teeming 
                             with vibrant marine life. The coastline is dotted

                             flowers. The Sunlit Realm is home to the Solari, a

                             like the sun. They are skilled artisans and

                             **The Twilight Belt:**                             

                             Encircling the planet is the Twilight Belt, a      
                             narrow region where day and night meet in perpetual
                             dusk. This area is a place of mystery and magic,   
                             where the sky is painted in hues of purple and     
                             orange, and the stars are always visible. The      
                             Twilight Belt is a land of rolling hills and       
                             ancient ruins, where the Veilwalkers, a nomadic    
                             people with the ability to manipulate shadows, make
                             their home. They are the keepers of ancient        
                             knowledge and guardians of the balance between     
                             light and dark.

                             by the glow of bioluminescent flora and fauna. The 
                             ocean here is a deep indigo, and the land is       
                             covered in forests of towering, luminescent trees. 
                             The Nocturnals, a race with skin as dark as the    
                             night and eyes that gleam like stars, inhabit this 
                             region. They are skilled navigators and            
                             astronomers, using the constellations to guide     
                             their way across the darkened seas.

                             to shimmer with the hues of twilight—deep purples  
                             and soft oranges that shift with the light. His    
                             hair is a cascade of silver, reminiscent of        
                             moonlight, and his eyes are a piercing shade of

                             respect of his peers and the attention of the      
                             elders. His family, known for their wisdom and

                             possesses a quiet confidence and a gentle demeanor,
                             preferring to observe and listen rather than       
                             dominate conversations. Despite his calm exterior, 
                             he harbors a fierce determination to protect the   
                             delicate balance of his world. Scotty is deeply

                             not limited to mere trickery; he can also use      
                             shadows to heal or protect, drawing on the magical

                             scattered across the Twilight Belt, believing that

                             of his world. His ultimate goal is to ensure that  
                             the balance between light and dark is preserved,

                             Veilwalkers, particularly his mentor, an elder     
                             named Lirael, who has guided him in honing his     
                             shadow-weaving abilities. He also shares a deep    
                             friendship with a Nocturnal astronomer named Kael, 
                             with whom he often exchanges knowledge and insights

                             drawing on the imagery of the twilight and the     
                             stars to convey his thoughts. He also carries a    
                             small, intricately carved obsidian pendant, a      
                             family heirloom that he believes connects him to   
                             the spirits of his ancestors. When deep in thought,
                             he can often be found tracing the patterns of the  
                             constellations with his fingers, a gesture that    
                             calms and centers him.

                             **Relationships:**                                 
                             Annie maintains strong ties with her family and the
                             elders of her community, often seeking their       
                             guidance and wisdom. She has formed a close bond   
                             with a Nocturnal astronomer named Kael, with whom  
                             she shares a mutual fascination for the stars and  
                             the mysteries they hold. Together, they explore the
                             boundaries of their respective magics, seeking to  
                             unlock the secrets of the cosmos.                  

                             **Role in the World:**                             
                             Annie serves as a bridge between the realms, using 
                             her shadow-weaving abilities to maintain the       
                             balance between light and dark. She is a keeper of 
                             ancient knowledge and a protector of the natural   
                             world, ensuring that the harmony of Thalassara is  
                             preserved. Her journey is one of discovery and     
                             enlightenment, as she seeks to unravel the         
                             mysteries of her world and her place within it.

                             Output: In the heart of the Twilight Belt, where   
                             the sky was a perpetual canvas of purples and      
                             oranges, Scotty and Annie walked side by side,     
                             their footsteps silent on the ancient stone path.  
                             The ruins of an old Veilwalker temple loomed ahead,
                             its shadowy silhouette blending seamlessly with the
                             dusk. The air was thick with the scent of          
                             night-blooming flowers, and the distant call of a  
                             nocturnal creature echoed through the hills.       

                             Scotty paused, tracing the patterns of the         
                             constellations with his fingers, a gesture that    
                             always calmed him. "The stars are unusually bright 
                             tonight," he remarked, his voice a soft murmur     
                             against the backdrop of the twilight.              

                             Annie nodded, her violet eyes reflecting the       
                             starlight. "Perhaps they have something to tell    
                             us," she replied, her voice carrying the weight of 
                             ancient wisdom. She had always believed that the   
                             stars held secrets, messages from the cosmos       
                             waiting to be deciphered.                          

                             Their destination was the heart of the temple, a   
                             place where the Veilwalkers believed the veil      
                             between worlds was thinnest. It was here that      
                             Scotty hoped to find answers, to uncover the       
                             secrets of the ancient ruins that had long         
                             intrigued him.                                     

                             As they entered the temple, the air grew cooler,   
                             and the shadows deepened. Scotty raised a hand,    
                             weaving the darkness into a soft glow that         
                             illuminated their path. The walls were adorned with
                             intricate carvings, depicting scenes of Veilwalkers
                             communing with the stars, their hands outstretched 
                             to the heavens.                                    

                             Annie ran her fingers over the carvings, her touch 
                             gentle and reverent. "These stories are as old as  
                             Thalassara itself," she mused. "They speak of a    
                             time when the balance between light and dark was   
                             first established."                                

                             Scotty nodded, his amethyst eyes scanning the      
                             carvings for clues. "And perhaps they hold the key 
                             to maintaining that balance," he said, his voice   
                             filled with quiet determination.                   

                             Together, they moved deeper into the temple, their 
                             footsteps echoing in the silence. At the center of 
                             the chamber, they found a stone altar, its surface 
                             etched with symbols that pulsed with a faint,      
                             otherworldly light.                                

                             Scotty reached out, his fingers brushing the       
                             symbols. As he did, a vision unfolded before him—a 
                             tapestry of light and shadow, weaving together the 
                             stories of Thalassara. He saw the Solari, their    
                             cities gleaming in the sun; the Nocturnals,        
                             navigating the darkened seas by starlight; and the 
                             Veilwalkers, guardians of the balance, weaving     
                             shadows to protect their world.                    

                             Annie watched, her heart swelling with awe and     
                             understanding. "The balance is not just a concept,"
                             she whispered. "It's a living, breathing force,    
                             woven into the very fabric of our world."          

                             Scotty nodded, his eyes shining with newfound      
                             clarity. "And it's up to us to preserve it," he    
                             said, his voice filled with resolve.               

                             As they left the temple, the stars seemed to shine 
                             even brighter, as if acknowledging their vow.      
                             Together, Scotty and Annie walked back into the    
                             twilight, their hearts united in purpose. They knew
                             that the path ahead would not be easy, but they    
                             were ready to face whatever challenges lay ahead,  
                             guided by the light of the stars and the wisdom of 
                             the ancients.                                      

                             In the vast expanse of Thalassara, where the ocean 
                             and the stars danced in eternal harmony, Scotty and
                             Annie found their place, as guardians of the       
                             balance, protectors of the beauty and mystery of   
                             their world. And as they journeyed onward, they    
                             carried with them the hope that their efforts would
                             ensure the magic of Thalassara endured for         
                             generations to come.

Declarative vs Imperative Syntax

The above example showed how to create a workflow using the declarative syntax via the parent_ids init param, but there are a number of declarative and imperative options for you to choose between. There is no functional difference, they merely exist to allow you to structure your code as is most readable for your use case. Possibilities are illustrated below.

Declaratively specify parents (same as above example):

from griptape.rules import Rule
from griptape.structures import Workflow
from griptape.tasks import PromptTask

workflow = Workflow(
    tasks=[
        PromptTask("Name an animal", id="animal"),
        PromptTask("Describe {{ parent_outputs['animal'] }} with an adjective", id="adjective", parent_ids=["animal"]),
        PromptTask("Name a {{ parent_outputs['adjective'] }} animal", id="new-animal", parent_ids=["adjective"]),
    ],
    rules=[Rule("output a single lowercase word")],
)

workflow.run()

Declaratively specify children:

workflow = Workflow(
    tasks=[
        PromptTask("Name an animal", id="animal", child_ids=["adjective"]),

Insert Parallel Tasks

Workflow.insert_tasks() provides a convenient way to insert parallel tasks between parents and children.

Info

By default, all children are removed from the parent task and all parent tasks are removed from the child task. If you want to keep these parent-child relationships, then set the preserve_relationship parameter to True.

Imperatively insert parallel tasks between a parent and child:

from griptape.rules import Rule
from griptape.structures import Workflow
from griptape.tasks import PromptTask

workflow = Workflow(
    rules=[Rule("output a single lowercase word")],
)

animal_task = PromptTask("Name an animal", id="animal")
adjective_task = PromptTask("Describe {{ parent_outputs['animal'] }} with an adjective", id="adjective")
color_task = PromptTask("Describe {{ parent_outputs['animal'] }} with a color", id="color")
new_animal_task = PromptTask("Name an animal described as: \n{{ parents_output_text }}", id="new-animal")

# The following workflow runs animal_task, then (adjective_task, and color_task)
# in parallel, then finally new_animal_task.
#
# In other words, the output of animal_task is passed to both adjective_task and color_task
# and the outputs of adjective_task and color_task are then passed to new_animal_task.
workflow.add_task(animal_task)
workflow.add_task(new_animal_task)
workflow.insert_tasks(animal_task, [adjective_task, color_task], new_animal_task)

workflow.run()

Bitshift Composition

Task relationships can also be set up with the Python bitshift operators >> and <<. The following statements are all functionally equivalent:

task1 >> task2
task1.add_child(task2)

task2 << task1
task2.add_parent(task1)

task3 >> [task4, task5]
task3.add_children([task4, task5])

When using the bitshift to compose operators, the relationship is set in the direction that the bitshift operator points. For example, task1 >> task2 means that task1 runs first and task2 runs second. Multiple operators can be composed – keep in mind the chain is executed left-to-right and the rightmost object is always returned. For example:

task1 >> task2 >> task3 << task4

is equivalent to:

task1.add_child(task2)
task2.add_child(task3)
task3.add_parent(task4)
