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 🙏

@adea-ai/catalog-core

v1.3.1

Published

Deterministic compiler for AI agent plugin marketplaces: parse, verify, merge, and compile plugin catalogs into provenance-checked static artifacts.

Readme

@adea-ai/catalog-core

Deterministic compiler for AI agent plugin marketplaces. Parse marketplace sources, verify provenance against pinned Git trees, merge into a canonical catalog, and compile provenance-checked static artifacts — byte-for-byte reproducible from the same inputs.

Pairs with @adea-ai/catalog-schema (the schemas), @adea-ai/source-adapters (source parsing), and @adea-ai/harness-adapters (per-harness materialization).

What's inside

  • Catalog compilation — merge parsed marketplace sources into one canonical, policy-checked catalog.
  • Integrity verification — sha256 content digests, SHA-pinned Git trees, and verifyArtifacts for published artifact sets.
  • Publication artifactscatalog.v1.json, catalog-summary.v1.json, categories.v1.json, compatibility.v1.json, sources.lock.json, and integrity.json with deterministic serialization.
  • Policy enforcement — repository protocol/host allowlists and source trust classification.

Install

bun add @adea-ai/catalog-core

Usage

import { verifyArtifacts } from '@adea-ai/catalog-core/publication'

Design rules

  • Same inputs, same bytes: compilation is deterministic and offline-safe.
  • Every artifact carries provenance; sources.lock.json pins the exact Git trees and digests a catalog was built from.
  • The compiler is a metadata boundary — it never installs or executes upstream plugins, hooks, MCP servers, or binaries.
