Agent and Model - AgentKit 文档

The VeADK Go v1.0.1 agent entry point is github.com/volcengine/veadk-go/agent/llmagent. llmagent.New extends ADK llmagent.Config with model defaults, config loading, PromptManager, Skills discovery, and knowledge-base tool injection.

Minimal Agent

import (
	veagent "github.com/volcengine/veadk-go/agent/llmagent"
	"google.golang.org/adk/agent"
	"google.golang.org/adk/agent/llmagent"
)

func newAssistant() (agent.Agent, error) {
	return veagent.New(&veagent.Config{
		Config: llmagent.Config{
			Name:        "assistant",
			Description: "Answer product and engineering questions.",
			Instruction: "You are a concise engineering assistant.",
		},
		ModelName:     "doubao-seed-1-6-250615",
		ModelProvider: "openai",
	})
}

If model fields are not set explicitly, VeADK Go reads MODEL_AGENT_NAME, MODEL_AGENT_PROVIDER, MODEL_AGENT_API_BASE, and MODEL_AGENT_API_KEY from environment variables or global config. For Ark paths without an API key, the source attempts to use an Ark token provider.

Agent with Tools

import (
	veagent "github.com/volcengine/veadk-go/agent/llmagent"
	"github.com/volcengine/veadk-go/tool/builtin_tools/web_search"
	"google.golang.org/adk/agent"
	"google.golang.org/adk/agent/llmagent"
	"google.golang.org/adk/tool"
)

func newSearchAgent() (agent.Agent, error) {
	searchTool, err := web_search.NewWebSearchTool(&web_search.Config{})
	if err != nil {
		return nil, err
	}

	return veagent.New(&veagent.Config{
		Config: llmagent.Config{
			Name:        "search_agent",
			Instruction: "Use web search when fresh information is needed.",
			Tools:       []tool.Tool{searchTool},
		},
	})
}

Key Configuration

Field	Purpose
`Config`	Embedded ADK `llmagent.Config` for name, description, instruction, tools, and callbacks.
`ModelName` / `ModelProvider`	Model name and provider. Defaults come from environment variables or global config.
`ModelAPIBase` / `ModelAPIKey`	Model endpoint and credential.
`ModelAPIKeyProvider`	Custom API key provider, such as the Ark token provider.
`ModelExtraConfig` / `ModelExtraHeaders`	Extra body/header fields passed to the model client.
`KnowledgeBase`	Automatically appends a knowledge-base retrieval tool.
`PromptManager`	Supplies the instruction when `Instruction` is not set explicitly.
`Skills`	Local skills root directories discovered during agent creation.
`DisableThought`	Adds extra config to disable reasoning content for supported models.

VeADK Go v1.0.1 configures long-term memory through the ADK runner MemoryService and mounts LoadLongMemoryTool when needed.
