gpt-multi-atomic-agents 0.3.2

Combine multiple graphql-based or function-based agents with dynamic routing - based on atomic-agents.

gpt-multi-atomic-agents

A simple dynamic multi-agent framework based on atomic-agents and Instructor. Uses the power of Pydantic for data and schema validation and serialization.

• compose Agents made of a system prompt, with a shared language of either Function Calls or else GraphQL mutations

• a router uses an LLM to process complex 'composite' user prompts, and automatically route them to the best sequence of your agents

  • the router rewrites the user prompt, to best suit each agent

• generate via OpenAI or AWS Bedrock or groq

• note: the !! framework is at an early stage !! - breaking changes will be indicated by increasing the minor version (major is still at zero).

Introduction

An LLM based Agents Framework using an Agent Oriented Programming approach to orchestrate agents using a shared language.

The agent language can either be Function Calling based, or else GraphQL based.

The framework is generic and allows agents to be defined in terms of a name, description, accepted input calls, and allowed output calls.

The agents communicate indirectly using a blackboard. The language is a composed of (Function or GraphQL mutation) calls: each agent specifies what it understands as input, and what calls it is able to generate. In this way, the agents can understand each other's output.

A router takes the user prompt and generates an agent execution plan.

The execution plan uses the best sequence of the most suitable agents, to handle the user prompt.

The router rewrites the user prompt to suit each agent, which improves quality and avoids unwanted output.

note: Optionally, the router can be run separately, allowing for human-in-the-loop feedback on the execution plan that the router generated. In this way, the user can collaborate more with the router, before the generative agents are actually executed.

• this allows the user to have more control over the output, and has the added benefit of reducing the perceived time taken to generate, since the user has intermediate interaction with the router.

Finally, the output is returned in the form of an ordered list of (Function or GraphQL) calls.

To read more about this approach, you can see this Medium article.

• note: the framework is at an early stage. The Evaluator is not currently implemented.

Integration

When integrating, depending on which kind of Agent Definitions are used, the client needs to:

• Function Calling Agents: client implements the functions. The client executes the functions according to the results (function calls) generated by this framework.
  • this approach is less flexible but good for simple use cases where GraphQL may be too complicated
• GraphQL based Agents: The client executes the GraphQL mutations on the GraphQL document they earler submitted to the framework.
  • this approach provides the most flexibility:
    • the input is a GraphQL schema with any previouly made mutation calls, the output is a set of mutation calls
    • the agents can communicate generations (modifications to data) by generating GraphQL mutations that match the given schema

Examples [Function Calls Based Approach]

Sim Life world builder

This is a demo 'Sim Life' world builder. It uses 3 agents (Creature Creature, Vegetation Creator, Relationship Creator) to process user prompts. The agents are defined in terms of functions. The output is a series of Function Calls which can be implemented by the client, to build the Sim Life world.

Definitions [Function Calls Based Approach]

The AddCreature function:

function_add_creature = FunctionSpecSchema(
    agent_name=creature_agent_name,
    function_name="AddCreature",
    description="Adds a new creature to the world (not vegetation)",
    parameters=[
        ParameterSpec(name="creature_name", type=ParameterType.string),
        ParameterSpec(name="allowed_terrain", type=ParameterType.string, allowed_values=terrain_types),
        ParameterSpec(name="age", type=ParameterType.int),
        ParameterSpec(name="icon_name", type=ParameterType.string, allowed_values=creature_icons),
    ]
)

The AddCreatureRelationship function:

function_add_relationship = FunctionSpecSchema(
    agent_name=relationship_agent_name,
    function_name="AddCreatureRelationship",
    description="Adds a new relationship between two creatures",
    parameters=[
        ParameterSpec(
            name="from_name", type=ParameterType.string
        ),
        ParameterSpec(
            name="to_name", type=ParameterType.string
        ),
        ParameterSpec(
            name="relationship_name",
            type=ParameterType.string,
            allowed_values=["eats", "buys", "feeds", "sells"],
        ),
    ],
)

Agent Definitions [Function Calls Based Approach]

The Creature Creator agent is defined declaratively in terms of:

• its description (a very short prompt)
• its input schema (a list of accepted function definitions)
• its output schema (a list of output function definitions)

Agents can collaborate and exchange information indirectly, by reusing the same function defintions via a blackboard.

def build_creature_agent():
    agent_definition = FunctionAgentDefinition(
        agent_name="Creature Creator",
        description="Creates new creatures given the user prompt. Ensures that ALL creatures mentioned by the user are created.",
        accepted_functions=[function_add_creature, function_add_relationship],
        input_schema=FunctionAgentInputSchema,
        initial_input=FunctionAgentInputSchema(
            functions_allowed_to_generate=[function_add_creature],
            previously_generated_functions=[]
        ),
        output_schema=FunctionAgentOutputSchema,
        topics=["creature"]
    )

    return agent_definition

Notes about the Creature Creator agent:

• this agent can only generate "AddCreature" function calls.
• the agent also accepts (understands) previous "AddCreature" calls, so that it knows what has already been created.
• additionally, this agent understands a subset of function calls from agents: here, it understands the "AddRelationship" function defined by function_add_relationship. See the example source code for more details.

Examples [GraphQL Based Approach]

Sim Life world builder

This is a demo 'Sim Life' world builder. It uses 3 agents (Creature Creature, Vegetation Creator, Relationship Creator) to process user prompts. The agents are defined declaratively in terms of GraphQL input schema, and allowed generated mutations. The output is a series of GraphQL mutations which can be executed by the client, to build the Sim Life world.

Definitions [GraphQL Based Approach]

The GraphQL schema:

type Creature {
  id: ID!
  creature_name: String!
  allowed_terrain: TerrainType!
  age: Int!
  icon_name: IconType!
}

type Vegetation {
  id: ID!
  vegetation_name: String!
  icon_name: IconType!
  allowed_terrain: TerrainType!
}

type Relationship {
  id: ID!
  from_name: String!
  to_name: String!
  relationship_kind: RelationshipType!
}
...

The GraphQL mutations that we want the Agents to generate, are distinct for each agent:

Creature Creator agent:

type Mutation {
  addCreature(input: CreatureInput!): Creature!
}

input CreatureInput {
  creature_name: String!
  allowed_terrain: TerrainType!
  age: Int!
  icon_name: IconType!
}

Vegetation Creator agent:

type Mutation {
  addVegetation(input: VegetationInput!): Vegetation!
}

input VegetationInput {
  vegetation_name: String!
  icon_name: IconType!
  allowed_terrain: TerrainType!
}

Agent Definitions [GraphQL Based Approach]

The Creature Creator agent is defined declaratively in terms of:

• its description (a very short prompt)
• its input schema (a list of accepted GraphQL schemas)
• its output schema (a list of output GraphQL mutation calls)

An agent is basically a composition of input and output schemas, together with a prompt.

Agents collaborate and exchange information indirectly via a blackboard, by reusing the same GraphQL schemas and mutation calls.

creatures_graphql = _read_schema("creature.graphql")
creature_mutations_graphql = _read_schema("creature.mutations.graphql")

def build_creature_agent():
    agent_definition = GraphQLAgentDefinition(
        agent_name="Creature Creator",
        description="Creates new creatures given the user prompt. Ensures that ALL creatures mentioned by the user are created.",
        accepted_graphql_schemas=[creatures_graphql, creature_mutations_graphql],
        input_schema=GraphQLAgentInputSchema,
        initial_input=GraphQLAgentInputSchema(
            mutations_allowed_to_generate=[creature_mutations_graphql],
            previously_generated_mutations=[]
        ),
        output_schema=GraphQLAgentOutputSchema,
        topics=["creature"]
    )

    return agent_definition

Notes about this agent:

• this agent can only generate mutations that are defined by creature_mutations_graphql from the file "creature.mutations.graphql".
• the agent also accepts (understands) previous mutations calls, so that it knows what has already been created (creature_mutations_graphql).
• additionally, this agent understands the shared GraphQL schema defined by creatures_graphql from the file "creature.graphql".
  • This array of GraphQL files can also be used to allow an Agent to understand the mutations output by other agents.
  • See the example source code for more details.

Using the Agents in a chat loop

The agents can be used together to form a chat bot:

from gpt_multi_atomic_agents import functions_expert_service, config
from . import agents

def run_chat_loop(given_user_prompt: str|None = None) -> list:
    CHAT_AGENT_DESCRIPTION = "Handles users questions about an ecosystem game like Sim Life"

    agent_definitions = [
        build_creature_agent(), build_relationship_agent(), build_vegatation_agent()  # for more capabilities, add more agents here
    ]

    _config = config.Config(
        ai_platform = config.AI_PLATFORM_Enum.bedrock_anthropic,
        model = config.ANTHROPIC_MODEL,
        max_tokens = config.ANTHROPIC_MAX_TOKENS,
        is_debug = False
        )

    return functions_expert_service.run_chat_loop(agent_definitions=agent_definitions, chat_agent_description=CHAT_AGENT_DESCRIPTION, _config=_config, given_user_prompt=given_user_prompt)

note: if given_user_prompt is not set, then run_chat_loop() will wait for user input from the keyboard

See the example source code for more details.

Example Execution [Function Calls Based Approach]

USER INPUT:

Add a sheep that eats grass

OUTPUT:

Generated 3 function calls
[Agent: Creature Creator] AddCreature( creature_name=sheep, icon_name=sheep-icon, land_type=prairie, age=1 )
[Agent: Plant Creator] AddPlant( plant_name=grass, icon_name=grass-icon, land_type=prairie )
[Agent: Relationship Creator] AddCreatureRelationship( from_name=sheep, to_name=grass, relationship_name=eats )

Because the framework has a dynamic router, it can handle more complex 'composite' prompts, such as:

Add a cow that eats grass. Add a human - the cow feeds the human. Add and alien that eats the human. The human also eats cows.

The router figures out which agents to use, what order to run them in, and what prompt to send to each agent.

Optionally, the router can be re-executed with user feedback on its genereated plan, before actually executing the agents.

The recommended agents are then executed in order, building up their results in the shared blackboard.

Finally, the framework combines the resulting calls together and returns them to the client.

Example run via Function Call based agents:

Example Execution [GraphQL Based Approach]

USER INPUT:

Add a sheep that eats grass

OUTPUT:

['mutation {\n    addCreature(input: {\n      creature_name: "sheep",\n      allowed_terrain: GRASSLAND,\n      age: 2,\n      icon_name: SHEEP\n    }) {\n      creature_name\n      allowed_terrain\n      age\n      icon_name\n    }\n  }']
['mutation {', '  addVegetation(input: {', '    vegetation_name: "Grass",', '    icon_name: GRASS,', '    allowed_terrain: LAND', '  }) {', '    vegetation_name', '    icon_name', '    allowed_terrain', '  }', '}']
['mutation {', '  addCreatureRelationship(input: {', '    from_name: "Sheep",', '    to_name: "Grass",', '    relationship_kind: EATS', '  }) {', '    id', '  }', '}']

Example run via GraphQL based agents:

Setup

0. Install Python 3.11 and poetry
