On this tutorial, we’ll discover methods to create good, multi-agent workflows utilizing the Mistral Brokers API’s Handoffs characteristic. This lets totally different brokers work collectively by passing duties to one another, enabling complicated issues to be solved in a modular and environment friendly approach. We’ll construct a system the place brokers collaborate to reply inflation-related questions—performing calculations, fetching knowledge on-line, and creating visualizations—to ship clear, correct, and dynamic responses.
Step 1: Organising dependencies
Putting in the libraries
pip set up mistralai pydanticLoading the Mistral API Key
You may get an API key from https://console.mistral.ai/api-keys
from getpass import getpass
MISTRAL_API_KEY = getpass('Enter Mistral API Key: ')Step 2: Agent Conditions and Setup
Initializing the Agent

The adjust_for_inflation operate calculates how a lot a given amount of cash could be value after accounting for inflation over time. It makes use of the compound formulation based mostly on the variety of years and the annual inflation fee. If the tip 12 months is earlier than the beginning 12 months, it returns an error. In any other case, it returns the adjusted worth together with the enter particulars. For instance, adjust_for_inflation(1000, 1899, 2025, 10) reveals what ₹1000 from 1899 could be value in 2025 at 10% inflation.

}Step 3: Creating the Brokers
Defining the totally different brokers
On this setup, we outline a multi-agent system utilizing Mistral Brokers API to deal with inflation-related financial queries. The principle agent (economics-agent) acts as a coordinator that routes duties to specialised brokers. The inflation-agent performs inflation adjustment calculations utilizing a customized operate. If the inflation fee is lacking from the question, the websearch-agent fetches it from the web. The calculator-agent handles complicated numerical computations with step-by-step reasoning, whereas the graph-agent makes use of the code interpreter to visualise inflation tendencies over time. Collectively, these brokers collaborate through handoffs to ship correct, dynamic responses to financial queries.
# Principal Agent
economics_agent = shopper.beta.brokers.create(
mannequin="mistral-large-latest",
identify="economics-agent",
description="Handles financial queries and delegates inflation calculations.",
)
# Inflation Perform Agent
inflation_agent = shopper.beta.brokers.create(
mannequin="mistral-large-latest",
identify="inflation-agent",
description="Agent that calculates inflation-adjusted worth utilizing a customized operate.",
instruments=[inflation_tool],
)
# Net Search Agent
websearch_agent = shopper.beta.brokers.create(
mannequin="mistral-large-latest",
identify="websearch-agent",
description="Agent that may search the web for lacking financial knowledge similar to inflation charges.",
instruments=[{"type": "web_search"}]
)
# Calculator Agent
from pydantic import BaseModel
class CalcResult(BaseModel):
reasoning: str
outcome: str
calculator_agent = shopper.beta.brokers.create(
mannequin="mistral-large-latest",
identify="calculator-agent",
description="Agent used to make detailed calculations.",
directions="When doing calculations, clarify step-by-step.",
completion_args=CompletionArgs(
response_format=ResponseFormat(
sort="json_schema",
json_schema=JSONSchema(
identify="calc_result",
schema=CalcResult.model_json_schema(),
)
)
)
)
# Graph Agent
graph_agent = shopper.beta.brokers.create(
mannequin="mistral-large-latest",
identify="graph-agent",
description="Agent that generates graphs utilizing code interpreter.",
directions="Use code interpreter to attract inflation tendencies.",
instruments=[{"type": "code_interpreter"}]
)Defining the Handoffs Obligations
This configuration defines how brokers delegate duties amongst one another:
- The Principal Agent (economics_agent) serves because the entry level and delegates queries both to the inflation_agent (for inflation calculations) or the websearch_agent (to fetch lacking knowledge like inflation charges).
- The inflation_agent, after receiving both the person question or web-fetched knowledge, can additional move duties to the calculator_agent (for detailed math) or graph_agent (to visualise tendencies).
- The websearch_agent can move management to the inflation_agent after retrieving required info, just like the inflation fee.
- calculator_agent and graph_agent are thought of terminal brokers. Nonetheless, elective mutual handoff is enabled in case one must do follow-up work (e.g., graphing a calculated outcome or vice versa).
# Principal Agent palms off to inflation_agent and websearch_agent
economics_agent = shopper.beta.brokers.replace(
agent_id=economics_agent.id,
handoffs=[inflation_agent.id, websearch_agent.id]
)
# Inflation Agent can delegate to calculator_agent or graph_agent if deeper evaluation or visualization is required
inflation_agent = shopper.beta.brokers.replace(
agent_id=inflation_agent.id,
handoffs=[calculator_agent.id, graph_agent.id]
)
# Net Search Agent can hand off to inflation_agent (after discovering the lacking fee)
websearch_agent = shopper.beta.brokers.replace(
agent_id=websearch_agent.id,
handoffs=[inflation_agent.id]
)
# Calculator and Graph brokers are terminal--they do not hand off additional
# But when wanted, we might allow them to hand off to one another:
calculator_agent = shopper.beta.brokers.replace(
agent_id=calculator_agent.id,
handoffs=[graph_agent.id] # Non-obligatory
)
graph_agent = shopper.beta.brokers.replace(
agent_id=graph_agent.id,
handoffs=[calculator_agent.id] # Non-obligatory
)Step 4: Operating the Agent
Instance A: What’s the present inflation fee in India?
On this instance, the immediate “What’s the present inflation fee in India?” is handed to the economics_agent, which is the principle entry level for dealing with financial queries. For the reason that query requires real-time knowledge that isn’t included within the agent’s static information, the economics_agent mechanically palms off the question to the websearch_agent, which is supplied with net search capabilities.
immediate = "What's the present inflation fee in India?"
response = shopper.beta.conversations.begin(
agent_id=economics_agent.id,
inputs=immediate
)
print(response.outputs[-1].content material[0].textual content)Instance B: What’s the inflation-adjusted worth of 5,000 from the 12 months 2010 to 2023 with an annual inflation fee of 6.5%. Clarify calculation steps and plot a graph with knowledge labels
This code block sends the immediate to an economics agent, checks if the agent triggers a selected operate name (adjust_for_inflation), executes that operate regionally with the supplied arguments, after which returns the computed outcome again to the agent. Lastly, it prints the agent’s response, which incorporates the inflation calculation clarification, together with the Python code to plot the development.

immediate = """What's the inflation-adjusted worth of 5,000 from the 12 months 2010 to 2023 with annual inflation fee of 6.5%.

response = shopper.beta.conversations.begin(
agent_id=economics_agent.id,
inputs=immediate
)
# Examine for operate name
if response.outputs[-1].sort == "operate.name" and response.outputs[-1].identify == "adjust_for_inflation":
args = json.hundreds(response.outputs[-1].arguments)
# Run native operate
function_result = json.dumps(adjust_for_inflation(**args))
# Return outcome to Mistral
result_entry = FunctionResultEntry(

)
response = shopper.beta.conversations.append(
conversation_id=response.conversation_id,
inputs=[result_entry]
)
print(response.outputs[-1].content material)
else:
print(response.outputs[-1].content material)The next code block was returned by the agent to plot the development of inflation-adjusted worth over time.
