For the last few months, most of the tools I build to run my own business have lived in scattered files on my own machine. A slash command here. A skill there. An MCP server I wrote for one job and kept reaching for.

As of today, they live somewhere you can reach too. We’ve put them in a marketplace, and you add the whole thing in one line:

/plugin marketplace add solo-super/marketplace

Seven plugins, installable in Claude Code and the Claude Desktop app. That’s the announcement. Here’s the part that matters.

The problem this fixes

If you use Claude to run a one-person business, you’ve probably noticed the same thing I did: you keep rebuilding the same handful of tools. The prompt that catches AI slop before you publish. The little routine that pressure-tests a decision. The check you run on a stranger who slid into your inbox with a suspiciously good offer.

You build it once, it works, and then it disappears into a folder you can’t find three weeks later. There’s no easy way to keep it, reuse it, or hand it to someone else. Every good tool you make dies a quiet death in your dotfiles.

A marketplace fixes that. It’s a catalog you add once, then install from — the same way an app store works, except everything in it is text you can read.

What it unlocks

  • Your toolkit travels with you. Add the marketplace on a new machine, or in the Desktop app, and install what you need in seconds. Nothing to copy-paste out of an old project.
  • The good stuff stops disappearing. These are the tools I actually use, packaged so they stay usable — by me, and now by you.
  • One line to hand someone a whole workflow. Point a friend at the marketplace and they’ve got the same setup, not a screenshot of your config.
  • It works where you work. Claude Code and the Claude Desktop app — same marketplace, same plugins.

What’s inside

Seven plugins at launch, each pulled from real work:

  • voice-superpowers — build a profile of how you actually write, edit any draft to match it, and catch AI tells before you publish.
  • decision-superpowers — Stoic, strategic, and cognitive-science frameworks to pressure-test a big call before you commit to it.
  • spain-ai-kit — Spain’s open government data (law, statistics, land registry, weather) straight from your assistant. Handy if you live here, like we do.
  • vet-superpowers — run an OSINT check on a cold client, pitch, or bot before you reply, hire, or sign.
  • web-superpowers — make your site accessible, findable, and fast: WCAG, SEO, and Core Web Vitals.
  • validate-superpowers — an eleven-gate gauntlet that tells you whether a thing is worth building before you build it.
  • framework-superpowers — three methodologies (PAST, SHAPE, and the Metric Mandate) for running an AI project that actually ships.

None of these are demos. They’re the tools we lean on, cleaned up so they run on anyone’s machine.

Installing it

Two steps. Add the catalog, then install a plugin:

/plugin marketplace add solo-super/marketplace
/plugin install voice-superpowers@solo-super

That’s it. The @solo-super on the end is the marketplace name — install any of the seven by swapping the name in front of it.

In the Claude Desktop app it’s a few clicks instead: open Customize → Plugins, click the +, choose Add from a repository, paste solo-super/marketplace, and install whatever you want from the list. We put a walkthrough with screenshots on the marketplace page.

A word on trust

Worth being straight about this. These are third-party plugins, so Claude will tell you they aren’t verified by Anthropic. That warning is correct — it shows up for any marketplace that isn’t Anthropic’s own, including ours.

Here’s what we can offer instead. Everything is open source and readable on GitHub before you install a single thing — browse it. It’s MIT licensed. I built and maintain each plugin from tools I use myself, and any plugin can be turned off or removed in a click. The honest version: install what you’d be comfortable reading the code of. That’s true here and everywhere.

Who it’s for, and what we’d love back

This is for solo operators and small teams who run everything themselves and want their AI to pull real weight — not another login, not another subscription, just tools you own.

So: add it, install one, and tell us what breaks. Open an issue, or get in touch. And if what you actually need is something bespoke — a custom agent, an MCP server, a skill built around your specific business — that’s the work we do. Tell us what you’re trying to do, and we’ll help figure out the rest.

The tools were always here. Now they’re one line away.
