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

@lythos/cold-pool

Cold pool service layer for the lythoskill ecosystem.

Status: stable — public API

What this is

A dedicated resource-holder package for the cold pool — the local cache of skill repositories at ~/.agents/skill-repos/ (configurable). This package is the only layer in the ecosystem that holds git side-effects. deck / curator / arena consume it instead of running git clone themselves.

CLI Commands

# Scan cold pool for unreferenced repos
bunx @lythos/[email protected] prune [--yes] [--dry-run]

# Validate lock file against cold pool
bunx @lythos/[email protected] validate [--lock ./skill-deck.lock]

Architecture

Three layers, sharing the project's intent → plan → execute pattern (cortex/wiki/01-patterns/2026-05-04-intent-plan-execute-fractal-architecture-pattern.md):

  • Resource layer — ColdPool class holds path, metadata index (MetadataDB), reconcile entry. Read-only accessors: resolveDir(), has(), list().
  • Plan layer — buildFetchPlan(coldPool, locator) → FetchPlan, buildValidationPlan(coldPool, locator) → ValidationReport, buildReconcilePlan(coldPool, desired) → ReconcilePlan. Pure data, no side effects, dry-run printable.
  • Execute layer — executeFetchPlan(plan, io: FetchIO), executeReconcilePlan(plan, io: ReconcileIO). IO is injectable; defaults to real git operations. Tests swap mocks.

Locator

Per ADR-20260502012643244, locators are FQ-only:

  • host.tld/owner/repo[/skill] — remote skill (monorepo, flat, or arbitrary subdir)
  • localhost/me/<skill> — local-only skill, no remote origin (host/owner/repo aligned)

Bare names and owner/repo shorthand are rejected — parseLocator returns null.

Granularity boundary

skill-deck.lock is working-set granularity (per-skill in .claude/skills/). The cold pool reconciliation runs at repo+ref granularity (per cloned repository at a specific commit). The two are not conflated. See ADR-20260507021957847.

Package status

This is internal monorepo infrastructure during the 0.9.x line. Public npm publish + stable API targeted for 0.10.0. See EPIC-20260507020846020 for the rollout plan.
