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 🙏

Readme

codeassembly-lifecycle

Canonical session-lifecycle event envelope, vocabulary, and lane fold.

This package defines the JSONL event format that instrumented skills append to the lifecycle-events root, and the pure fold that turns that log into lane and session state. Producers and consumers share it so a log means the same thing on both sides: the codeassembly CLI ships the helpers that write events, and Fleet reads them back.

Release notes — v0.3.0 (2026-08-07)

🎉 Features

  • 🚨 Breaking: Rename the harness id to rovo and qualify the frontmatter key (#1199)

    Renames the internal ID for the Rovo Dev harness from rovodev to rovo. --harness rovo replaces --harness rovodev in every command.

    Separately, renames the harnesses frontmatter key (which narrows a skill to particular harnesses) to supported-harnesses: to avoid confusion.

Installation

pnpm add codeassembly-lifecycle

What it exports

| Export | Covers | | ------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------- | | EVENT_TYPES, EventEnvelope, EventType, isEventType | The event envelope and the closed vocabulary of event types | | parseEventLine | Reads one line of a JSONL event log into an envelope | | applyLaneEvent, applySessionEvent, createLaneState, createSessionState, deriveLaneStatus, deriveSessionStatus | The fold from events to lane and session state | | resolveLaneCwd, resolveLaneRecency | Lane projections a renderer needs | | parseTicketRef | Reads a ticket reference out of a branch name or identifier |

The fold is pure, and everything exported is browser-bundle-safe, so a client renders from the same state a server derives.
