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 🙏

@kedge-agentic/harness-core

v0.2.0

Published

Framework-free core of @kedge-agentic/harness. Orchestrator, task registry, output schema registry, exit evaluator, in-memory run store, event stream — plus the HTTP client SDK. Zero NestJS coupling.

Readme

@kedge-agentic/harness-core

框架无关的 harness orchestrator — 给 iterative agent task 用。

类型: 框架无关库 · 状态: public · v0.2.0

用途

Iterative agent task 框架,从原 @kedge-agentic/harness 包迁出。 让 solution 定义一个 HarnessTask (目标 / 分数阈值 / 退出条件),驱动它在多轮里跟 agent backend (ccaas Session, MCP client) 对话,直到退出条件触发。

  • TaskRegistry — 注册 / 查找 HarnessTask 定义
  • Orchestrator — 跑 round 循环,调 SessionProvider + McpClient, 评估退出
  • InMemoryRunStore — 本地/dev 用的简单 RunStore 实现
  • RunEventStream / RunEventStreamRegistry — run progress 事件的 pub/sub
  • OutputSchemaRegistry — per-task Zod schema,校验 agent 输出
  • 工具函数: assembleContext, extractOutput, shouldExit, pollUntilComplete

零 NestJS 耦合。 NestJS 适配在 @kedge-agentic/harness-nest

主要导出

import {
  TaskRegistry,
  Orchestrator,
  InMemoryRunStore,
  RunEventStream,
  RunEventStreamRegistry,
  OutputSchemaRegistry,
  assembleContext,
  extractOutput,
  shouldExit,
  pollUntilComplete,
  // 类型
  HarnessTask,
  HarnessRun,
  RunStore,
  RunProgress,
  RunFilters,
  IterationRecord,
  McpClient,
  SessionProvider,
  SessionResult,
  TokenUsage,
  HarnessEventEnvelope,
} from '@kedge-agentic/harness-core'

用法

const registry = new TaskRegistry()
registry.register({
  id: 'doc-optimizer',
  prompt: '改进这段文档',
  scoreThreshold: 85,
  maxRounds: 5,
})

const orchestrator = new Orchestrator({
  sessionProvider,
  mcpClient,
  taskRegistry: registry,
  runStore: new InMemoryRunStore(),
})

const run = await orchestrator.startRun({ taskId: 'doc-optimizer', input: '...' })
for await (const evt of new RunEventStream(run.id).subscribe()) {
  console.log(evt)
}

依赖

  • 运行时: 无
  • 无 peerDeps,无框架耦合
