📋 Prerequisites

• ✅ Go 1.24.1 or later
• 🔑 LLM provider API key (OpenAI, DeepSeek, etc.)
• 💡 5 minutes to build your first intelligent agent

🚀 Run the Example

Get started in 3 simple steps:

# 1️⃣ Clone and setup
git clone https://github.com/trpc-group/trpc-agent-go.git
cd trpc-agent-go

# 2️⃣ Configure your LLM
export OPENAI_API_KEY="your-api-key-here"
export OPENAI_BASE_URL="your-base-url-here"  # Optional

# 3️⃣ Run your first agent! 🎉
cd examples/runner
go run . -model="gpt-4o-mini" -streaming=true

What you'll see:

• 💬 Interactive chat with your AI agent
• ⚡ Real-time streaming responses
• 🧮 Tool usage (calculator + time tools)
• 🔄 Multi-turn conversations with memory

Try asking: "What's the current time? Then calculate 15 * 23 + 100"

func main() {
    // Create model.
    modelInstance := openai.New("deepseek-chat")

    // Create tool.
    calculatorTool := function.NewFunctionTool(
        calculator,
        function.WithName("calculator"),
        function.WithDescription("Execute addition, subtraction, multiplication, and division. "+
            "Parameters: a, b are numeric values, op takes values add/sub/mul/div; "+
            "returns result as the calculation result."),
    )

    // Enable streaming output.
    genConfig := model.GenerationConfig{
        Stream: true,
    }

    // Create Agent.
    agent := llmagent.New("assistant",
        llmagent.WithModel(modelInstance),
        llmagent.WithTools([]tool.Tool{calculatorTool}),
        llmagent.WithGenerationConfig(genConfig),
    )

    // Create Runner.
    runner := runner.NewRunner("calculator-app", agent)

    // Execute conversation.
    ctx := context.Background()
    events, err := runner.Run(ctx,
        "user-001",
        "session-001",
        model.NewUserMessage("Calculate what 2+3 equals"),
    )
    if err != nil {
        log.Fatal(err)
    }

    // Process event stream.
    for event := range events {
        if event.Object == "chat.completion.chunk" {
            fmt.Print(event.Choices[0].Delta.Content)
        }
    }
    fmt.Println()
}

func calculator(ctx context.Context, req calculatorReq) (calculatorRsp, error) {
    var result float64
    switch req.Op {
    case "add", "+":
        result = req.A + req.B
    case "sub", "-":

🏗️ Architecture Overview

Architecture

🔄 Execution Flow

1. 🚀 Runner orchestrates the entire execution pipeline with session management
2. 🤖 Agent processes requests using multiple specialized components
3. 🧠 Planner determines the optimal strategy and tool selection
4. 🛠️ Tools execute specific tasks (API calls, calculations, web searches)
5. 💾 Memory maintains context and learns from interactions
6. 📚 Knowledge provides RAG capabilities for document understanding

Key packages:

Package	Responsibility
agent	Core execution unit, responsible for processing user input and generating responses.
runner	Agent executor, responsible for managing execution flow and connecting Session/Memory Service capabilities.
model	Supports multiple LLM models (OpenAI, DeepSeek, etc.).
tool	Provides various tool capabilities (Function, MCP, DuckDuckGo, etc.).
session	Manages user session state and events.
memory	Records user long-term memory and personalized information.
knowledge	Implements RAG knowledge retrieval capabilities.
planner	Provides Agent planning and reasoning capabilities.

Execution flow

Using Built-in Agents

For most applications you do not need to implement the agent.Agent interface yourself. The framework already ships with several ready-to-use agents that you can compose like Lego bricks:

Agent	Purpose
LLMAgent	Wraps an LLM chat-completion model as an agent.
ChainAgent	Executes sub-agents sequentially.
ParallelAgent	Executes sub-agents concurrently and merges output.
CycleAgent	Loops over a planner + executor until stop signal.

Multi-Agent Collaboration Example

// 1. Create a base LLM agent.
base := llmagent.New(
    "assistant",
    llmagent.WithModel(openai.New("gpt-4o-mini")),
)

// 2. Create a second LLM agent with a different instruction.
translator := llmagent.New(
    "translator",
    llmagent.WithInstruction("Translate everything to French"),
    llmagent.WithModel(openai.New("gpt-3.5-turbo")),
)

// 3. Combine them in a chain.
pipeline := chainagent.New(
    "pipeline",
    chainagent.WithSubAgents([]agent.Agent{base, translator}),
)

// 4. Run through the runner for sessions & telemetry.
run := runner.NewRunner("demo-app", pipeline)
events, _ := run.Run(ctx, "user-1", "sess-1",
    model.NewUserMessage("Hello!"))
for ev := range events { /* ... */ }

The composition API lets you nest chains, cycles, or parallels to build complex workflows without low-level plumbing.
