import asyncio

from agno.agent import Agent
from agno.knowledge.knowledge import Knowledge
from agno.knowledge.reader.website_reader import WebsiteReader
from agno.vectordb.pgvector import PgVector

db_url = "postgresql+psycopg://ai:ai@localhost:5532/ai"

knowledge = Knowledge(
    vector_db=PgVector(
        table_name="website_documents",
        db_url=db_url,
    ),
)

agent = Agent(
    knowledge=knowledge,
    search_knowledge=True,
)

async def main():
    # Crawl and add website content to knowledge base
    await knowledge.add_content_async(
        url="https://docs.agno.com/introduction",
        reader=WebsiteReader(max_depth=2, max_links=20),
    )

    # Query the knowledge base
    await agent.aprint_response(
        "What are the main features of Agno?",
        markdown=True,
    )
