Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@zhin.js/core

Zhin.js 核心框架包,提供插件系统、Feature 架构、AI 智能体、消息路由等全部核心能力。

核心概念

Plugin(插件)

插件是 Zhin.js 的基本组织单位。每个插件拥有独立的生命周期和上下文,通过 usePlugin() Hook 访问框架能力。

import { usePlugin, MessageCommand } from '@zhin.js/core'

const { addCommand, addTool, addCron, onMounted, onDispose } = usePlugin()

onMounted(() => console.log('插件已挂载'))
onDispose(() => console.log('插件已卸载'))

addCommand(
  new MessageCommand('hello <name:string>')
    .desc('打招呼')
    .action((_, result) => `Hello, ${result.params.name}!`)
)

Feature(特性抽象)

Feature 是 Zhin.js 的核心扩展机制。所有内置功能均继承自 Feature 抽象基类,提供统一的注册/注销、插件归属追踪和 JSON 序列化能力。

Feature (抽象基类)
├── CommandFeature    — 消息命令       addCommand()
├── ToolFeature       — AI 可调用工具   addTool()
├── SkillFeature      — 技能聚合       declareSkill()
├── CronFeature       — 定时任务       addCron()
├── DatabaseFeature   — 数据模型       defineModel()
├── ComponentFeature  — 消息组件       addComponent()
├── ConfigFeature     — 插件配置       addConfig()
└── PermissionFeature — 权限管理

每个 Feature 都会在 Plugin.prototype 上注入对应的扩展方法(如 addCommandaddTool),插件通过 usePlugin() 获取这些方法。

Adapter(适配器)

适配器将不同聊天平台接入 Zhin.js,统一消息收发接口。

// 适配器通过 Adapter.register 静态注册
Adapter.register('my-platform', MyAdapter)

每个适配器可以通过 addTool() 注册平台工具,通过 declareSkill() 将工具聚合为 AI 可理解的技能。

MessageDispatcher(消息路由)

三阶段消息处理管线:

消息到达 → Guardrail(守卫) → Route(路由) → Handle(处理)
                │                    │                │
           权限/频率检查         命令 or AI?      执行命令 / AI Agent
  • Guardrail — 鉴权、速率限制、黑名单等前置检查
  • Route — 判断消息是命令还是 AI 对话
  • Handle — CommandFeature 处理命令,ZhinAgent 处理 AI 对话

AI 模块(ZhinAgent)

内置 AI 智能体,支持 OpenAI / Ollama 等大模型。

用户消息 → 速率限制 → 工具过滤 → 会话记忆 → LLM 调用 → 输出
                                    │
                              三条路径选择:
                         闲聊(0工具)→ 1次 LLM
                         快速(无参数工具)→ 预执行 + 1次 LLM
                         Agent(有参数工具)→ 多轮 tool-calling

核心子模块:

| 模块 | 说明 | |------|------| | SessionManager | 会话管理(内存/数据库) | | ContextManager | 上下文构建与滑动窗口 | | ConversationMemory | 话题感知、链式摘要 | | UserProfileStore | 用户画像 | | RateLimiter | 频率限制 | | FollowUpManager | 定时提醒(持久化) | | ToneDetector | 情绪分析 | | OutputParser | 多模态输出解析 |
