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.

@gethmy/harness

Execution primitives for the Harmony agent daemon (@gethmy/agent).

The package holds the parts of an agent run that do not depend on the daemon's queue or config: git worktrees, pull request helpers, repo verification, run containment, the Claude Agent SDK runner, model sizing and the logger.

Dependency direction is agent → harness → shared. Importing from @gethmy/agent here is never correct.

Installation

Most users never install this package directly. @gethmy/agent depends on it, and the hmy front door carries it too:

npm i -g @gethmy/cli

Building your own driver? Depend on @gethmy/harness from your driver's package.json rather than installing it globally.

Prerequisites

Node.js >= 20 or Bun >= 1.0
Git
Claude Code available to the agent SDK

Diagnostics

hmy harness resolutions [--probe-sdk]

Prints what this delivery resolves — the claude executable and the MCP server launch — as JSON. --probe-sdk starts a real SDK query far enough to capture the executable the SDK decided to spawn, then aborts it.
