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 🙏

@karkata-ai/core

v0.1.1

Published

Framework-neutral agent runtime with tools, sessions, cancellation, streaming, and human input.

Readme

@karkata-ai/core

文档 | English | 中文

Karkata 的框架无关 Agent Runtime。它提供模型循环、规范化消息、工具注册、持续会话、取消与超时、流式状态和 Human-in-the-Loop 协议,不依赖 DOM 或特定模型厂商。

安装

npm install @karkata-ai/core zod

使用

import { Agent, defineTool, type LLMAdapter } from '@karkata-ai/core'
import { z } from 'zod'

const llm: LLMAdapter = {
  async invoke(_request, { signal }) {
    signal.throwIfAborted()
    return { message: { role: 'assistant', content: '完成' } }
  },
}

const ping = defineTool({
  name: 'ping',
  description: 'Return a visible confirmation',
  inputSchema: z.object({ value: z.string() }),
  execute: ({ value }) => ({ value }),
})

const agent = new Agent({ llm, tools: [ping], timeoutMs: 30_000 })
const result = await agent.send('开始')

LLMAdapter 负责 Provider 协议;使用 OpenAI-compatible 服务时可以直接安装 @karkata-ai/openai-compatible。工具输出必须是可序列化、模型可见的 ToolOutput。同一 Agent 实例一次只运行一个 send(),成功运行提交会话,失败、中断和超时运行回滚。

状态通过 subscribe() 读取,Human-in-the-Loop 问题通过 subscribeRequests() 接收并使用 respond() 回答。启用 streaming 后,state.partialResponse 只用于临时 UI 投影,不写入模型历史。

完整设计和 API 示例见 Karkata 仓库。
