• System immediate – Guides the agent’s habits, outlining how and when to make use of every instrument to realize its analysis aims

Within the following sections, we talk about the LLM and instruments in additional element.

Giant language mannequin

The LLM influences the habits of the agent in addition to the standard of the generated response. We determined to make use of Anthropic’s Claude 4 Sonnet on Amazon Bedrock for its means to plan and execute advanced duties, however you need to use one of many different models supported by Amazon Bedrock or one other mannequin supplier.

from strands.fashions import BedrockModel
bedrock_model = BedrockModel(
    model_id="us.anthropic.claude-sonnet-4-20250514-v1:0",
    region_name="us-east-1",
)
agent = Agent(mannequin=bedrock_model)

Instruments

Instruments assist prolong brokers’ capabilities and work together with exterior providers equivalent to Tavily. We applied the next instruments to allow our agent to carry out deep analysis over the web and supply a formatted output:

• web_extract – Extract the total web page content material from a webpage
• web_crawl – Crawl total web sites and scrape their content material
• format_research_response – Rework uncooked analysis content material into clear, well-structured, and correctly cited responses
• write_markdown_file – Save the analysis output in Markdown ahead on the native file system

To outline a instrument with the Strands Brokers SDK, you possibly can merely wrap a Python perform with the @instrument decorator and supply a Python docstring with the instrument description. Let’s discover an instance of how we applied the web_search instrument utilizing Tavily’s search endpoint.The search endpoint lets brokers uncover related webpages primarily based on a pure language question. Outcomes embrace URLs, title, content material snippets, semantic scores, and even the total content material of matched pages. You’ll be able to fine-tune searches with parameters equivalent to:

• Max variety of outcomes – Limits the variety of outcomes to an higher certain
• Time vary filtering – Limits the outcomes to content material printed inside a selected timeframe
• Area restrictions – Restricts outcomes to particular domains

See the next code:

@instrument
def web_search(
    question: str, time_range: str | None = None, include_domains: str | None = None
) -> str:
    """Carry out an internet search. Returns the search outcomes as a string, with the title, url, and content material of every outcome ranked by relevance.
    Args:
        question (str): The search question to be despatched for the net search.
        time_range (str | None, optionally available): Limits outcomes to content material printed inside a selected timeframe.
            Legitimate values: 'd' (day - 24h), 'w' (week - 7d), 'm' (month - 30d), 'y' (yr - 365d).
            Defaults to None.
        include_domains (listing[str] | None, optionally available): An inventory of domains to limit search outcomes to.
            Solely outcomes from these domains shall be returned. Defaults to None.
    Returns:
        formatted_results (str): The net search outcomes
    """
    shopper = TavilyClient(api_key=os.getenv("TAVILY_API_KEY"))
    formatted_results = format_search_results_for_agent(
        shopper.search(
            question=question,
            max_results=10,
            time_range=time_range,
            include_domains=include_domains
        )
    )
    return formatted_results

LLMs rely closely on the instrument definition and outline to find out how and when to make use of them. To enhance instrument accuracy, take into account the next finest practices:

• Clearly clarify when the instrument needs to be used and its functionally
• Use sort hints within the perform signature to explain the parameters, return varieties, and default values
• Element every parameter and supply examples of the accepted codecs
