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 🙏

v0.3.0

Published

Wire contract for the Itera Learning Engine: spool-line envelope, episode shapes, engine API shapes.

Readme

The v1 episode accepts optional project_root. The engine validates it as a canonical absolute ancestor of cwd and preserves it as the work context root. Old clients can omit it. This addition does not introduce schema version 2.

Version 0.3.0 emits episode version 2. The legacy episodeSchema, episodeBatchSchema, and v1 spool reader keep their literal version 1 contract. acceptedEpisodeBatchSchema accepts both versions. safeParseCapturedSpoolLine accepts old v1 lines and v2 capture lines, including session-end. The 0.3.0 agent groups turns into sessions and retains ordered turn moments. Engine v2 acceptance and migration 0089 must deploy before the client release.
