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 🙏

init-kmp

A Claude Code skill that scaffolds production-ready Kotlin Multiplatform + Compose Multiplatform projects (Room, Koin, type-safe navigation, virtual-time tests) — or audits an existing one against the same 8 architecture standards.

Grounded in real incidents from building a real 6-plan KMP+CMP app, not textbook clean-architecture theory. See reference/gotchas.md.

Prerequisites

  • macOS required for the iOS half (Xcode build/verify gate); Android-only scaffolding and audits work on any OS.
  • JDK 17+ to launch Gradle — the daemon auto-provisions JDK 21 itself via the pinned gradle-daemon-jvm.properties, which needs network access on first build.
  • Android SDK with ANDROID_HOME set (or a local.properties you create yourself / your IDE creates for you — the scaffolded project ships without one on purpose).
  • Xcode 26+ for the xcode26 toolchain line; an older Xcode install works fine with the older toolchain line instead.
  • Python 3 to run scripts/scaffold.py and scripts/verify.py.

Install

Claude Code:

npx init-kmp

Installs to ~/.claude/skills/init-kmp/ by default. Or copy this folder there yourself.

Cursor / Codex CLI / GitHub Copilot / Windsurf/Devin / OpenCode (all confirmed to auto-read a root-level AGENTS.md):

npx init-kmp --target=.agent-skills/init-kmp
echo "See .agent-skills/init-kmp/AGENTS.md for the init-kmp skill." >> AGENTS.md

Cline (reads .clinerules/, not root AGENTS.md):

npx init-kmp --target=.agent-skills/init-kmp
mkdir -p .clinerules && echo "See .agent-skills/init-kmp/AGENTS.md for the init-kmp skill." > .clinerules/init-kmp.md

Full per-agent rationale in the project README.

Use

  • /init-kmp new (or just /init-kmp in an empty directory) — scaffold a new project.
  • /init-kmp audit (or just /init-kmp in an existing Gradle project) — score the project against the 8 standards.

Not using Claude Code? See AGENTS.md for the same instructions in agent-agnostic form.

Toolchain (as of 2026-07)

Two verified lines — see reference/toolchain.md for the full version tables and the research behind each pairing:

  • Xcode 26+: Kotlin 2.3.21 / Compose Multiplatform 1.11.1 / AGP 9.0.1 / KSP 2.3.9
  • Older Xcode: Kotlin 2.3.0 / Compose Multiplatform 1.10.3 / AGP 9.0.1 / KSP 2.3.6
