fmt.Print(event.Response.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", "-":
result = req.A - req.B
case "mul", "*":
result = req.A * req.B
case "div", "/":
result = req.A / req.B
default:
return calculatorRsp{}, fmt.Errorf("invalid operation: %s", req.Op)
}
return calculatorRsp{Result: result}, nil
}
type calculatorReq struct {
A float64 `json:"A" jsonschema:"description=First integer operand,required"`

Op string `json:"Op" jsonschema:"description=Operation type,enum=add,enum=sub,enum=mul,enum=div,required"`
}
type calculatorRsp struct {
Result float64 `json:"result"`
}
```
## Examples
The `examples` directory contains runnable demos covering every major feature.
### 1. Tool Usage
- [examples/agenttool](examples/agenttool) – Wrap agents as callable tools.
- [examples/multitools](examples/multitools) – Multiple tools orchestration.
- [examples/duckduckgo](examples/duckduckgo) – Web search tool integration.
- [examples/filetoolset](examples/filetoolset) – File operations as tools.
- [examples/fileinput](examples/fileinput) – Provide files as inputs.
- [examples/agenttool](examples/agenttool) shows streaming and non-streaming
patterns.
### 2. LLM-Only Agent ([examples/llmagent](examples/llmagent))
- Wrap any chat-completion model as an `LLMAgent`.
- Configure system instructions, temperature, max tokens, etc.
- Receive incremental `event.Event` updates while the model streams.
### 3. Multi-Agent Runners ([examples/multiagent](examples/multiagent))
- **ChainAgent** – linear pipeline of sub-agents.
- **ParallelAgent** – run sub-agents concurrently and merge results.
- **CycleAgent** – iterate until a termination condition is met.
### 4. Graph Agent ([examples/graph](examples/graph))
- **GraphAgent** – demonstrates building and executing complex, conditional
workflows using the `graph` and `agent/graph` packages. It shows
how to construct a graph-based agent, manage state safely, implement
conditional routing, and orchestrate execution with the Runner.
- Multi-conditional fan-out routing:
```go
// Return multiple branch keys and run targets in parallel.
sg := graph.NewStateGraph(schema)
sg.AddNode("router", func(ctx context.Context, s graph.State) (any, error) {
return nil, nil
})
sg.AddNode("A", func(ctx context.Context, s graph.State) (any, error) {
return graph.State{"a": 1}, nil
})
sg.AddNode("B", func(ctx context.Context, s graph.State) (any, error) {
return graph.State{"b": 1}, nil
})
sg.SetEntryPoint("router")
sg.AddMultiConditionalEdges(
"router",
func(ctx context.Context, s graph.State) ([]string, error) {
return []string{"goA", "goB"}, nil
},
map[string]string{"goA": "A", "goB": "B"}, // Path map or ends map
)
sg.SetFinishPoint("A").SetFinishPoint("B")
```

- How to configure, call tools and customize prompts.
### 6. Knowledge ([examples/knowledge](examples/knowledge))
- Basic RAG example: load sources, embed to a vector store, and search.
- How to use conversation context and tune loading/concurrency options.
### 7. Telemetry & Tracing ([examples/telemetry](examples/telemetry))
- OpenTelemetry hooks across model, tool and runner layers.
- Export traces to OTLP endpoint for real-time analysis.
### 8. MCP Integration ([examples/mcptool](examples/mcptool))
- Wrapper utilities around **trpc-mcp-go**, an implementation of the
**Model Context Protocol (MCP)**.
- Provides structured prompts, tool calls, resource and session messages that
follow the MCP specification.
- Enables dynamic tool execution and context-rich interactions between agents
and LLMs.
### 9. Debug Web Demo ([examples/debugserver](examples/debugserver))
- Launches a **debug Server** that speaks ADK-compatible HTTP endpoints.
- Front-end: [google/adk-web](https://github.com/google/adk-web) connects via
`/run_sse`, streams agent responses in real-time.
- Great starting point for building your own chat UI.
Other notable examples:
- [examples/humaninloop](examples/humaninloop) – Human in the loop.
- [examples/codeexecution](examples/codeexecution) – Secure code execution.
See individual `README.md` files in each example folder for usage details.
## 🏗️ 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
```go
// 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.
