Quick Start

from tool_registry_module import tool, build_registry_openai, build_registry_anthropic, ToolContext
from pydantic import BaseModel
from typing import Annotated


class UserData(BaseModel):
    name: str
    age: int


@tool(description="Process user information")
def process_user(
    input: UserData, 
    context: ToolContext[dict] = None  # Automatically excluded from schema
) -> UserData:
    # context parameter is available for use but won't appear in AI tool schema
    return input


# Build registries for different providers
openai_registry = build_registry_openai([process_user])
anthropic_registry = build_registry_anthropic([process_user])

# Use with respective APIs
openai_tools = [entry["representation"] for entry in openai_registry.values()]
anthropic_tools = [entry["representation"] for entry in anthropic_registry.values()]

Multi-Provider Examples

OpenAI Function Calling

from tool_registry_module import tool, build_registry_openai
import openai

@tool(description="Get weather information")
def get_weather(location: str, unit: str = "celsius") -> str:
    return f"Weather in {location}: 22°{unit[0].upper()}"

# Build OpenAI registry
registry = build_registry_openai([get_weather])
tools = [entry["representation"] for entry in registry.values()]

# Use with OpenAI
client = openai.OpenAI()
response = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "What's the weather in Paris?"}],
    tools=tools
)

Anthropic Claude

from tool_registry_module import tool, build_registry_anthropic
import anthropic

registry = build_registry_anthropic([get_weather])
tools = [entry["representation"] for entry in registry.values()]

# Use with Anthropic
client = anthropic.Anthropic()
response = client.messages.create(
    model="claude-3-sonnet-20240229",
    max_tokens=1000,
    messages=[{"role": "user", "content": "What's the weather in Paris?"}],
    tools=tools
)

AWS Bedrock

from tool_registry_module import tool, build_registry_bedrock
import boto3

registry = build_registry_bedrock([get_weather])
tools = [entry["representation"] for entry in registry.values()]

# Use with Bedrock
client = boto3.client("bedrock-runtime")
# Use tools in your Bedrock converse API calls

Google Gemini

from tool_registry_module import tool, build_registry_gemini
import google.generativeai as genai

registry = build_registry_gemini([get_weather])
tools = [entry["representation"] for entry in registry.values()]

# Use with Gemini
model = genai.GenerativeModel('gemini-pro')
# Use tools in your Gemini function calling

Mistral AI

from tool_registry_module import tool, build_registry_mistral
from mistralai.client import MistralClient

registry = build_registry_mistral([get_weather])
tools = [entry["representation"] for entry in registry.values()]

# Use with Mistral
client = MistralClient()
# Use tools in your Mistral function calling

Advanced Usage

Parameter Filtering

Using ToolContext (Recommended)

Use ToolContext to mark parameters that should be automatically excluded from schemas:

from tool_registry_module import tool, ToolContext
from typing import Annotated

@tool(description="Process user data with context")
def process_data(
    user_input: str,
    context: ToolContext[dict],  # Direct ToolContext generic
    session: Annotated[str, ToolContext],  # Annotated ToolContext
    debug_flag: bool = False
) -> str:
    # context and session parameters are automatically excluded from the schema
    # but available for use in your function
    return f"Processed: {user_input}"

ToolContext Features:

• Automatic exclusion - No need to manually specify ignore_in_schema
• Type safety - Full type hints with generic support
• Reference preservation - Objects maintain their references for mutation within functions
• Multiple forms - Both direct (ToolContext[T]) and annotated (Annotated[T, ToolContext]) syntax
• Union validation - Prevents incorrect usage in union types

Supported ToolContext patterns:

# Direct generic types
param1: ToolContext[dict]
param2: ToolContext[str] 

# Annotated types
param3: Annotated[str, ToolContext]
param4: Annotated[dict, ToolContext, "description"]

# Union types will raise TypeError (prevented for safety)
# param5: Union[str, ToolContext[dict]]  # ❌ Not allowed

Reference Preservation Example:

from tool_registry_module import tool, ToolContext

# Context objects maintain their references for mutation
@tool(description="Track user interactions")
def track_interaction(
    action: str,
    user_context: ToolContext[dict]  # This dict can be modified
) -> str:
    # Modify the context object - changes persist outside function
    user_context["actions"] = user_context.get("actions", [])
    user_context["actions"].append(action)
    user_context["last_action"] = action
    return f"Tracked: {action}"

# Usage
context = {"user_id": "123"}
track_interaction("login", user_context=context)
track_interaction("view_profile", user_context=context)

# Context object is modified:
print(context)  
# {'user_id': '123', 'actions': ['login', 'view_profile'], 'last_action': 'view_profile'}

Legacy Parameter Filtering

You can still manually exclude parameters using ignore_in_schema:

@tool(
    description="Calculate area with debug output",
    ignore_in_schema=["debug_mode", "context"]
)
def calculate_area(length: float, width: float, debug_mode: bool = False, context: str = "calc") -> float:
    if debug_mode:
        print(f"Calculating area for {length} x {width}")
    return length * width

Cache Control (Anthropic)

Add cache control for better performance with Anthropic:

@tool(
    description="Expensive computation",
    cache_control={"type": "ephemeral"}
)
def expensive_function(data: str) -> str:
    # Expensive computation here
    return processed_data

Registry Utilities

from tool_registry_module import get_tool_info, validate_registry

# Get information about a specific tool
info = get_tool_info(registry, "process_user")
print(info["description"])

# Validate registry structure
is_valid = validate_registry(registry)

Tool Use Handling

The registry is a dictionary that enables dynamic function calling for AI tool responses:

from tool_registry_module import tool, build_registry_anthropic

@tool(description="Add two numbers")
def add_numbers(a: int, b: int) -> int:
    return a + b

@tool(description="Get weather info")
def get_weather(city: str, units: str = "celsius") -> str:
    return f"Weather in {city}: 22°{units[0].upper()}"

# Build registry
registry = build_registry_anthropic([add_numbers, get_weather])

# Handle tool use responses dynamically
def handle_tool_calls(tool_calls, registry):
    results = []
    for tool_call in tool_calls:
        tool_name = tool_call.name
        tool_args = tool_call.input
        
        if tool_name in registry:
            try:
                # Get function from registry and execute
                tool_func = registry[tool_name]["tool"]
                result = tool_func(**tool_args)
                results.append({
                    "tool_use_id": tool_call.id,
                    "content": str(result)
                })
            except Exception as e:
                results.append({
                    "tool_use_id": tool_call.id,
                    "error": f"Error: {e}"
                })
        else:
            results.append({
                "tool_use_id": tool_call.id,
                "error": f"Tool '{tool_name}' not found"
            })
    
    return results

# Registry structure: {tool_name: {"tool": callable, "representation": provider_format}}
# Use registry[tool_name]["tool"] for dynamic function calling
