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 🙏

Skills 机制

基于 Claude Skills 标准的三层渐进式披露架构。

快速开始

import { SkillRegistry, createSkillActivationTool, buildSkillsSystemPrompt } from '@loom-node/skills';

// 初始化
const registry = new SkillRegistry();
await registry.scanDirectory('./skills');

// 生成系统提示词
const systemPrompt = buildSkillsSystemPrompt(registry);

// 注册激活工具
const skillTool = createSkillActivationTool(registry);

架构

Layer 1: Discovery (启动时)

  • 扫描 SKILL.md frontmatter
  • 提取 name + description
  • 成本: ~50 tokens/skill

Layer 2: Activation (运行时)

  • LLM 语义匹配
  • 调用 activate_skill 工具
  • 加载完整 SKILL.md
  • 成本: ~500-2000 tokens/skill

Layer 3: Execution (按需)

  • SKILL.md 指令驱动
  • LLM 调用 read_file/bash
  • 懒加载 scripts/references/assets

技能目录结构

my-skill/
├── SKILL.md           # 必需
├── scripts/           # 可选
├── references/        # 可选
└── assets/            # 可选

SKILL.md 格式

---
name: my-skill
description: Skill description for semantic matching
allowed-tools: read_file, write_file, bash
---
