Plugins are designed to be self-contained and modular, allowing you to create individual plugins for specific security policies, and apply them globally at the runner level. This means that a security plugin can be configured once and applied to every agent that uses the runner, ensuring consistent security guardrails across your entire application without repetitive code. diff --git a/docs/sessions/memory.md b/docs/sessions/memory.md index e62704542f..a9c9d360d3 100644 --- a/docs/sessions/memory.md +++ b/docs/sessions/memory.md @@ -68,36 +68,25 @@ required. === "Python" ```py - from google.adk.memory import InMemoryMemoryService - memory_service = InMemoryMemoryService() + --8<-- "examples/inline/python/sessions/memory/001-inmemorymemoryservice.py" ``` === "TypeScript" ```typescript - import { InMemoryMemoryService } from '@google/adk'; - const memoryService = new InMemoryMemoryService(); + --8<-- "examples/inline/typescript/sessions/memory/002-inmemorymemoryservice.ts" ``` === "Go" ```go - import ( - "google.golang.org/adk/v2/memory" - "google.golang.org/adk/v2/session" - ) - - // Services must be shared across runners to share state and memory. - sessionService := session.InMemoryService() - memoryService := memory.InMemoryService() + --8<-- "examples/inline/go/sessions/memory/003-inmemorymemoryservice.go.txt" ``` === "Java" ```java - import com.google.adk.memory.InMemoryMemoryService; - - InMemoryMemoryService memoryService = new InMemoryMemoryService(); + --8<-- "examples/inline/java/sessions/memory/004-inmemorymemoryservice.java" ``` === "Kotlin" @@ -114,96 +103,7 @@ simplicity. === "Python" ```py - import asyncio - from google.adk.agents import LlmAgent - from google.adk.sessions import InMemorySessionService, Session - from google.adk.memory import InMemoryMemoryService # Import MemoryService - from google.adk.runners import Runner - from google.adk.tools import load_memory # Tool to query memory - from google.genai.types import Content, Part - - # --- Constants --- - APP_NAME = "memory_example_app" - USER_ID = "mem_user" - MODEL = "gemini-flash-latest" # Use a valid model - - # --- Agent Definitions --- - # Agent 1: Simple agent to capture information - info_capture_agent = LlmAgent( - model=MODEL, - name="InfoCaptureAgent", - instruction="Acknowledge the user's statement.", - ) - - # Agent 2: Agent that can use memory - memory_recall_agent = LlmAgent( - model=MODEL, - name="MemoryRecallAgent", - instruction="Answer the user's question.
