Universal Agent Interactive Protocol - Python SDK with a declarative framework to build Agentic AI Services

Universal Agent Interactive Protocol (UAIP)

     

   

An open protocol for interoperability between autonomous agents and application services.

UAIP defines how autonomous agents interact with applications through explicit stages, workflows, and tasks. It guarantees invocation order and reliable execution, replacing ad-hoc prompting with verifiable contracts. UAIP is 78% more token efficient than existing protocols, eliminating context overflow and semantic loss.

UAIP token efficiency across benchmarks

Quick Start

# Install UAIP SDK
pip install uaip

# Initialize a new workflow project
uaip init my-store

# Run the workflow server
cd my-store
python main.py

This starts a UAIP server at specified port that agents can interact with via /initialize and /execute.

Universal Agent Interactive Protocol

You control agent autonomy by specifying legal tasks at each stage and valid transitions between stages. For example: agents cannot checkout before adding items to cart. UAIP enforces these rules, validates prerequisites before task execution, and ensures agents follow your defined path through the application.

Tasks

Tasks are the smallest granularity of callable business logic. Several tasks can be defined within 1 stage. Ensuring these tasks are avialable or callable at the stage.

@task(description="Add product to shopping cart")
def add_to_cart(self, state: State, product_id: str, quantity: int) -> dict:
    """Adds item to cart and updates state"""
    cart_items = state.get("cart.items", [])
    cart_items.append({"product_id": product_id, "quantity": quantity})
    state.set("cart.items", cart_items)
    return {"success": True, "cart_size": len(cart_items)}

Stages

A stage is a logical sub-step towards a goal, Stage can have several tasks grouped together, that an agent can call at a given point.

@stage(name="product")
class ProductStage:
    @task(description="Add product to shopping cart")
    def add_to_cart(self, state: State, product_id: str, quantity: int) -> dict:
        """Adds item to cart"""
        
    @task(description="Save product to wishlist")
    def add_to_wishlist(self, state: State, product_id: str) -> dict:
        """Saves item for later"""
        

State

A state is a global context that is maintained by the protocol, parts of which can get propagated to other stages as the agent transitions and navigates through stages.

# State persists across stages and tasks
state.set("cart.items", [{"product_id": "123", "quantity": 2}])
state.set("user.email", "[e-mail]")
state.set("cart.total", 99.99)

# Retrieve state values
items = state.get("cart.items", [])
user_email = state.get("user.email")

Workflow

A workflow is a logic grouping of several stages, you can define graphs of stages which represent legal moves to other stages within workflow.

@workflow(name="shopping")
class ShoppingWorkflow:
    discovery = DiscoveryStage      # Search and filter products
    product = ProductStage          # View product details
    selection = SelectionStage      # Add to cart/wishlist
    cart = CartStage                # Manage cart items
    checkout = CheckoutStage        # Complete purchase
    
    transitions = {
        discovery: [product, selection],
        product: [selection, discovery],
        selection: [cart, discovery, product],
        cart: [checkout, selection, discovery],
        checkout: []
    }

Examples

Multi-Stage Workflow

@workflow(name="amazon_shopping")
class AmazonShoppingWorkflow:
    browse = BrowseStage         # Search and filter products
    select = SelectStage         # Add items to cart
    checkout = CheckoutStage     # Complete transaction
    
    transitions = {
        browse: [select],
        select: [browse, checkout],
        checkout: []
    }

Stage with Tasks

@stage(name="browse")
class BrowseStage:
    @task(description="Search for products by keyword")
    def search_products(self, state: State, query: str) -> dict:
        """Returns matching products"""
        
    @task(description="Filter products by price range")
    def filter_by_price(self, state: State, min_price: float, max_price: float) -> dict:
        """Filters current results by price"""
        
    @task(description="Sort products by rating or price")
    def sort_products(self, state: State, sort_by: str) -> dict:
        """Sorts: 'rating', 'price_low', 'price_high'"""

@stage(name="select")
class SelectStage:
    @task(description="Add product to shopping cart")
    def add_to_cart(self, state: State, product_id: str, quantity: int) -> dict:
        """Adds item to cart"""
        
    @task(description="Save product to wishlist")
    def add_to_wishlist(self, state: State, product_id: str) -> dict:
        """Saves item for later"""
        
    @task(description="Star product for quick access")
    def star_product(self, state: State, product_id: str) -> dict:
        """Stars item as favorite"""
        
    @task(description="View product details")
    def view_details(self, state: State, product_id: str) -> dict:
        """Shows full product information"""

Prerequisites

@stage(name="checkout", prerequisites=["cart.items", "user.payment_method"])
class CheckoutStage:
    @task(description="Apply discount code")
    def apply_discount(self, state: State, code: str) -> dict:
        """Validates and applies discount"""
        
    @task(description="Complete purchase")
    def complete_purchase(self, state: State) -> dict:
        """Processes payment and creates order"""
