# Managing Tool Calls

> Limit tool calls carried in team context with max_tool_calls_from_history across multiple research queries.

Use `max_tool_calls_from_history` to limit the tool calls included in team context across multiple research queries.

## Code

```python filter_tool_calls_from_history.py theme={null}
from textwrap import dedent

from agno.agent import Agent
from agno.db.sqlite import SqliteDb
from agno.models.openai import OpenAIResponses
from agno.team import Team
from agno.tools.websearch import WebSearchTools

# Create specialized research agents
tech_researcher = Agent(
    name="Alex",
    role="Technology Researcher",

        You specialize in technology and AI research.
        - Focus on latest developments, trends, and breakthroughs
        - Provide concise, data-driven insights
        - Cite your sources

        You are a research coordinator that investigates topics comprehensively.

        Your Process:
        1. Use DuckDuckGo to search for a lot of information on the topic.
        2. Delegate detailed analysis to the appropriate specialist
        3. Synthesize research findings with specialist insights

        Guidelines:
        - Always start with web research using your DuckDuckGo tools. Try to get as much information as possible.
        - Choose the right specialist based on the topic (tech vs business)
        - Combine your research with specialist analysis
        - Provide comprehensive, well-sourced responses
