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 🙏

@soldunio/skills

v1.0.0

Published

AI agent skill for the Solduino Arduino/ESP32 Solana library. Installs into Cursor and Claude Code skill directories via npx.

Readme

@soldunio/skills

AI agent skill for Solduino — the Solana library for Arduino/ESP32 microcontrollers.

Installing this skill teaches your AI code editor (Cursor, Claude Code) how to write correct Solduino firmware: keypair management, transaction building and signing, RPC usage, SPL token instructions, PDA derivation, sensor-to-chain (DePIN) patterns, and the embedded memory pitfalls that generic Solana knowledge misses.

Install

Into the current project:

npx @soldunio/skills

Globally (available in every project):

npx @soldunio/skills --global

Options:

| Flag | Effect | |---|---| | (none) | Install into ./.cursor/skills/ and ./.claude/skills/ | | -g, --global | Install into ~/.cursor/skills/ and ~/.claude/skills/ | | --cursor | Install for Cursor only | | --claude | Install for Claude Code only | | --dir <path> | Install into a custom skills directory | | --force | Overwrite an existing installation |

What's inside

skills/solduino/
├── SKILL.md        # Core guidance: platform rules, memory rules, canonical tx flow
├── reference.md    # Full API tables for every Solduino class
└── examples.md     # Complete sketch patterns (transfer, custom programs, DePIN)

Once installed, the skill activates automatically when the agent works with Solduino / Solana-on-ESP32 code, or explicitly via /solduino in Cursor.

Publishing (maintainers)

npm publish

The package is scoped to the soldunio npm org and publishConfig.access is set to public, so no extra flags are needed. It ships only bin/ and skills/ (see the files field in package.json).
