vibe-agent 0.0.3

VibeAgent / VibeAgent（中文）

VibeAgent 是一个轻量的 AI Agent SDK，核心目标是用尽量少的抽象把「对话 → 推理 → 工具调用 → 工具结果回传 → 继续推理」这条链路跑通，并保持与 OpenAI 协议的兼容性（chat.completions / tools）。

安装

pip install vibe-agent

快速开始

1) 初始化推理层（Inferrer）

你需要显式传入 server_base_url 与 API Key（或通过环境变量提供）。

• API Key 优先级：server_apikey 参数 > 环境变量 INFER_API_KEY
• 如果两者都缺失，会抛出异常

import asyncio
from vibe_agent.infer_layer import Inferrer

async def main():
    inferrer = Inferrer(
        server_base_url="https://openrouter.ai/api/v1",
        server_apikey="YOUR_API_KEY"
    )

    resp = await inferrer.run(
        model="google/gemini-3-flash-preview",
        messages=[{"role": "user", "content": "你好"}],
    )
    print(resp.choices[0].message.content)

asyncio.run(main())

2) 使用 ChatConfig 管理推理参数

ChatConfig 用于集中存储推理参数（messages、tools、temperature 等），并允许通过 extra_params 透传符合 OpenAI 协议的自定义参数。

from vibe_agent.infer_layer import ChatConfig

config = ChatConfig(
    model="google/gemini-3-flash-preview",
    messages=[{"role": "user", "content": "总结一下这段话"}],
    temperature=0.2,
    extra_params={"top_k": 40},
)

3) 使用对话管理层（DialogueManager）自动执行工具

DialogueManager 会在模型返回 tool_calls 时，自动调用本地工具函数，并把工具结果按 OpenAI 协议（role=tool）回传给模型，直至模型不再请求工具或达到 max_turns。

import asyncio
from vibe_agent.infer_layer import Inferrer
from vibe_agent.dialogue_layer import DialogueManager

def get_weather(city: str):
    return f"{city} weather is sunny."

async def main():
    inferrer = Inferrer(
        server_base_url="https://openrouter.ai/api/v1",
        server_apikey="YOUR_API_KEY"
    )
    dm = DialogueManager(inferrer=inferrer, tools_map={"get_weather": get_weather})

    tools = [
        {
            "type": "function",
            "function": {
                "name": "get_weather",
                "description": "Get weather information for a city.",
                "parameters": {
                    "type": "object",
                    "properties": {
                        "city": {"type": "string", "description": "City name"}
                    },
                    "required": ["city"]
                }
            }
        }
    ]

    resp = await dm.chat(
        messages=[{"role": "user", "content": "北京天气怎么样？"}],
        model="google/gemini-3-flash-preview",
        tools=tools
    )
    print(resp.choices[0].message.content)

asyncio.run(main())

4) 自动把 Python 函数转换为 tools schema（并带本地缓存）

如果你不想手写 tools schema，可以用 register_tools()：

• 输入：若干 Python callable
• 输出：自动生成并注入符合 OpenAI SDK 的 tools 列表
• 缓存：如果函数源码未变化，会复用本地缓存（默认 .vibe_tool_cache.json）避免重复消耗推理成本

import asyncio
from vibe_agent.infer_layer import Inferrer
from vibe_agent.dialogue_layer import DialogueManager

def calculate_sum(a: int, b: int):
    \"\"\"Calculate sum of two integers.\"\"\"
    return a + b

async def main():
    inferrer = Inferrer(
        server_base_url="https://openrouter.ai/api/v1",
        server_apikey="YOUR_API_KEY"
    )
    dm = DialogueManager(inferrer=inferrer)

    await dm.register_tools([calculate_sum], model="google/gemini-3-flash-preview")

    resp = await dm.chat(
        messages=[{"role": "user", "content": "帮我算 123 + 456"}],
        model="google/gemini-3-flash-preview",
    )
    print(resp.choices[0].message.content)

asyncio.run(main())

环境变量

• INFER_API_KEY: 当 server_apikey 未传入时使用

安全提示

• 不要把 API Key 写进代码或提交到 Git
• .trae/rules/pypi.md 用于本地保存 PyPI Token，必须保持不入库

VibeAgent (English)

VibeAgent is a lightweight AI Agent SDK that keeps the core loop minimal: conversation → inference → tool calls → tool execution → tool result back to the model. It stays compatible with the OpenAI-style chat.completions interface and tools schema.

Installation

pip install vibe-agent

Quick Start

1) Initialize Inferrer

You must pass server_base_url explicitly, and provide an API key via argument or environment.

• API key priority: server_apikey argument > INFER_API_KEY env var
• If both are missing, an exception is raised

import asyncio
from vibe_agent.infer_layer import Inferrer

async def main():
    inferrer = Inferrer(
        server_base_url="https://openrouter.ai/api/v1",
        server_apikey="YOUR_API_KEY"
    )

    resp = await inferrer.run(
        model="google/gemini-3-flash-preview",
        messages=[{"role": "user", "content": "Hello"}],
    )
    print(resp.choices[0].message.content)

asyncio.run(main())

2) Manage parameters with ChatConfig

ChatConfig stores inference parameters (messages/tools/temperature/etc.) and supports passing extra OpenAI-compatible fields via extra_params.

3) Use DialogueManager for tool execution

DialogueManager detects tool_calls in model responses, executes local tool callables, and appends OpenAI-style tool messages back to the conversation until no more tool calls are requested (or max_turns is reached).

4) Auto-generate tools schema from Python callables (with local caching)

Use register_tools() to let the model generate OpenAI tools schema from Python functions. Results are cached by function source hash in .vibe_tool_cache.json (default).
