Five Pebbles(五块卵石)

PyPI Python License

简介

五块卵石(Five Pebbles) 是一个基于生命周期钩子的插件化 Agent 框架。它提供了灵活、可扩展的方式来构建和运行 AI Agent,支持终端 REPL、Web 界面和远程协议调用等多种交互方式。

灵感来源于《Rain World》中的迭代器「五块卵石」—— 冷静、理性、追求优雅的解决方案。


特性

  • 🤖 强大的 Agent 引擎 — 基于生命周期钩子,在 Agent 运行的各个阶段注入自定义逻辑
  • 🔌 插件化架构 — 通过插件动态扩展工具、命令和行为,无需修改核心代码
  • 🖥️ 终端 REPL — 交互式命令行界面,语法高亮、自动补全、流式输出
  • 🌐 Web 界面 — 浏览器端图形界面,开箱即用
  • 🔗 ACP 协议 — JSON-RPC 2.0 远程调用,轻松集成 IDE、CI/CD、其他 Agent

快速安装

基本安装(核心 + CLI)

pip install fp-agent

安装后即可使用终端 REPL:

fp

安装所有组件

pip install fp-agent[all]

选择性安装

# 核心 + Web 界面
pip install fp-agent[webui]

# 核心 + ACP 协议
pip install fp-agent[acp]

要求 Python >= 3.11。

Windows 用户:推荐安装 Git for Windows(安装时勾选"Git Bash"并添加到 PATH),以获得完整的 Unix 命令支持。未安装时会自动降级到 cmd.exe,仅支持 Windows 原生命令。


快速使用

终端 REPL(默认)

fp

进入交互式对话:

Web 界面

pip install fp-agent[webui]
fp --webui

浏览器访问 http://localhost:7860

ACP 远程调用

pip install fp-agent[acp]
fp --acp

然后通过 JSON-RPC 调用:

curl http://localhost:9090 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"chat","params":{"message":"你好"}}'

配置

命令行选项

fp [OPTIONS]

选项:
  --config FILE        指定配置文件路径
  --webui             启动 Web 界面模式
  --acp               启动 ACP Server 模式
  --model NAME        指定 LLM 模型名称
  --host HOST         监听地址(默认 127.0.0.1)
  --port PORT         监听端口
  --debug             启用调试模式
  --quiet             静默模式
  --version           显示版本信息

配置文件

默认读取 ~/.config/fp/config.yaml

llm:
  provider: openai
  model: gpt-4o
  temperature: 0.7
  api_key: ${OPENAI_API_KEY}

session:
  storage: file
  path: ~/.local/share/fp/sessions
