BedrockTool

Bases: BaseTool[ToolTypeDef]

A class for defining tools for Bedrock LLM calls.

from mirascope.core import prompt_template
from mirascope.core.bedrock import bedrock_call


def format_book(title: str, author: str) -> str:
    return f"{title} by {author}"


@bedrock_call("anthropic.claude-3-haiku-20240307-v1:0", tools=[format_book])
@prompt_template("Recommend a {genre} book")
def recommend_book(genre: str):
    ...


response = recommend_book("fantasy")
if tool := response.tool:  # returns an `BedrockTool` instance
    print(tool.call())

tool_schema classmethod 

tool_schema() -> ToolTypeDef

Constructs a JSON Schema tool schema from the BaseModel schema defined.

Example: 

from mirascope.core.bedrock import BedrockTool


def format_book(title: str, author: str) -> str:

tool_type = BedrockTool.type_from_fn(format_book)
print(tool_type.tool_schema())  # prints the Bedrock-specific tool schema
