Knowledge base retrieval

Overview

Tool identifier load_knowledgebase. System tools are built-in tools that VeADK mounts automatically based on the agent’s configuration — you don’t add them to the tools list yourself. When you pass a knowledgebase to the agent, VeADK mounts the load_knowledgebase tool. The agent decides on its own when to query the knowledge base and which keywords to search with, then uses the retrieved knowledge as context for its answer. For backend types, initialization, and data ingestion, see the knowledge base docs.

Usage

from veadk import Agent, Runner
from veadk.knowledgebase import KnowledgeBase

# Build a knowledge base (see the knowledge base docs for backends and ingestion)
knowledgebase = KnowledgeBase(backend="local", index="company_faq")

agent = Agent(
    name="kb_agent",
    model_name="doubao-seed-2-1-pro-260628",
    instruction="When answering, retrieve from the knowledge base where helpful.",
    knowledgebase=knowledgebase,  # mounts load_knowledgebase automatically
)

runner = Runner(agent=agent)

Notes

System tools are managed by the framework: just provide a knowledgebase — you don’t add load_knowledgebase to the tools list yourself. The agent decides when to call it based on its instruction and user input.
