Step 06: Web Tools

Your Agent wants to see the bigger world. At the root, they are just two new tools.

Prerequisites

cp default_workspace/config.example.yaml default_workspace/config.user.yaml
# Edit config.user.yaml to add your API key
# Uncomment websearch and webread sections
# Add your websearch api key

What We Will Build

An LLM may know how to write Python, but it cannot know the latest trends in the Python ecosystem. This opens up the world beyond the local file system and the LLM's training data.

Key Components

• WebSearchProvider: Web search providers.
• WebReadProvider: Web reading providers.
• Tools: websearch and webread tools.

src/mybot/provider/web_search/

class WebSearchProvider(ABC):
    async def search(self, query: str) -> list[SearchResult]: ...

src/mybot/provider/web_read/

class WebReadProvider(ABC):
    async def read(self, url: str) -> ReadResult: ...

src/mybot/tools/websearch_tool.py

@tool(...)
async def websearch(query: str, session: "AgentSession") -> str:
    results = await provider.search(query)

    if not results:
        return "No results found."
    output = []
    for i, r in enumerate(results, 1):
        output.append(f"{i}. **{r.title}**\n   {r.url}\n   {r.snippet}")
    return "\n\n".join(output)

src/mybot/tools/webread_tool.py

@tool(...)
async def webread(url: str, session: "AgentSession") -> str:
    result = await provider.read(url)
    if result.error:
        return f"Error reading {url}: {result.error}"

    return f"**{result.title}**\n\n{result.content}"
