Building Generative Agents

Synchronous Invocation

Use Blades synchronous invocation to have the Agent return a complete answer at once.

Behavior: After sending a request with the synchronous Run call, it blocks and waits until the model generates the full reply, then returns the result in one go.
Return value: A complete Message object

Code Example

Prerequisites

1. Install Blades: `go get github.com/go-kratos/blades`
2. Configure the model provider (e.g., OpenAI): Set environment variables `OPENAI_API_KEY` and `OPENAI_BASE_URL`

package main

import (
    "context"
    "log"
    "os"

    "github.com/go-kratos/blades"
    "github.com/go-kratos/blades/contrib/openai"
)

func main() {
    // Set Environment Variables for OpenAI
    provider := openai.NewChatProvider()
    agent := blades.NewAgent(
        "Run Agent",
        blades.WithProvider(provider),
        blades.WithModel("deepseek-chat"),
    )
    params := map[string]any{
        "topic":    "The Future of Artificial Intelligence",
        "audience": "General reader",
    }
    prompt, err := blades.NewPromptTemplate().
        System("please summarize {{.topic}}。", params).
        User("please answer for {{.audience}} in a clear and accurate manner.", params).
        Build()
    if err != nil {
        log.Fatal(err)
    }
    result, err := agent.Run(context.Background(), prompt)
    if err != nil {
        log.Fatal(err)
    }
    log.Println(result.Text())
}
