Long-term memory retrieval

Overview

Tool identifier load_memory. 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 long_term_memory to the agent, VeADK mounts the load_memory tool. Across sessions, the agent decides on its own when to query long-term memory to retain user preferences, history, and other long-lived state. For long-term memory backends and configuration, see the long-term memory docs.

Usage

from veadk import Agent, Runner
from veadk.memory.long_term_memory import LongTermMemory

long_term_memory = LongTermMemory(backend="local", app_name="ltm_demo")

agent = Agent(
    name="memory_agent",
    model_name="doubao-seed-2-1-pro-260628",
    instruction="Retrieve long-term memory when useful, to give personalized, continuous answers.",
    long_term_memory=long_term_memory,  # mounts load_memory automatically
)

runner = Runner(agent=agent)

Notes

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