Prebuilt tools

smallestai.tools gives your crew agent ready-made tools its LLM can call. Each tool plugs into the crew’s ToolRegistry in one line and is also usable on its own. The third-party libraries they wrap install as optional extras, imported lazily.

Web search (Exa)

$
pip install "smallestai[exa]"     # reads EXA_API_KEY

Register it inside a crew node so the model can call it:

1
from smallestai.tools import ExaSearchTool
2
3
class Assistant(OutputCrewNode):
4
    def __init__(self):
5
        super().__init__(name="assistant")
6
        self.tool_registry = ToolRegistry()
7
        self.tool_registry.discover(self)          # your own @function_tools
8
        ExaSearchTool().register(self.tool_registry)  # + web search, one line
9
        self.tool_schemas = self.tool_registry.get_schemas()

Or call it directly, outside a crew:

1
results = await ExaSearchTool().run(query="latest voice AI news")

Discovering tools

1
from smallestai.tools import list_tools, get_tool
2
3
list_tools()            # {"exa_search": ExaSearchTool, ...}
4
get_tool("exa_search")  # the tool class by name

If the extra isn’t installed

Importing smallestai.tools never pulls a third-party library. Running a tool without its extra raises a clear error, for example pip install "smallestai[exa]". The registry is built to add more tools over time; they follow the same pattern.
