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 🙏

@capyclaw/canvas-workbench(Canvas 文档工作台运行时)

DeepSeek Harness 插件:Canvas 文档编辑器运行时 + 工具面。普通用户请装 @capyclaw/canvas-suite;本包是套件里的运行时子包,也可单独安装用于调试。

  • 22 个 canvas_* MCP 工具:契约探测(canvas_capabilities)/ 文档读写 / 块级写作 / 页面与排版命令 / 导出 HTML / 审计 / 撤销重做 / 截图等。
  • 浏览器实时编辑器:http://127.0.0.1:39313/(本机 relay 托管,装完即有)。 agent 的每一步修改实时出现在页面里;编辑器是权威状态源(编辑器权威桥)。
  • 本机桥(127.0.0.1:39313):agent(MCP,streamable-http /mcp)与编辑器 之间的指令/回执/镜像/截图通道。不依赖任何桌面系统,一条 dsh 会话 + 一个 浏览器标签页即可工作。

独立运行(调试)

node server/relay.mjs --port 39313 [--dir <数据目录>]
# /healthz 健康检查;/mcp 为 MCP 端点;/ 为编辑器页面

生产形态不由本包自行拉起:套件 services.json 声明 canvas-workbench 服务, 由 dsh-service-broker 以独立进程拉起并注入端口/数据目录。

运行时架构

| 件 | 位置 | 说明 | |----|------|------| | relay | server/relay.mjs | HTTP 服务:编辑器静态托管 + /mcp + /healthz | | 工具面 | server/tools/ | 22 个 canvas_* 工具(kernel + capabilities + domains) | | 契约 | contract/ | 工具契约快照(由 canvas_capabilities 对齐) | | 编辑器 | editor/ | 浏览器壳(会话/传输/心跳/截图) | | 公共基建 | server/shared/ | service-host 等快照(独立运行时不依赖 dsh ctx) |

安装后工具组 canvas_* 出现在 agent 工具清单里;详见套件包 @capyclaw/canvas-suite 的 README。
