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 🙏

关于 Thinking 模式

Thinking 模式适用于需要复杂推理的任务(数学、代码分析、多步骤规划等)。

  • 启用 Thinking 模式时,temperature / top_p 等采样参数对推理阶段无效。
  • 推荐使用 doubao-seed-1-6-thinking 或 Seed 2.0 系列模型。
  • 当 Thinking 模式禁用时,节点会自动将 reasoning_content 流式增量镜像到普通 assistant text,确保 n8n AI Agent 能正常聚合输出。
  • 多轮工具调用场景下,节点会自动将上一轮的 reasoning_content 注入到后续请求,符合火山方舟 API 要求。
