SpecThis

Claude Code Plugin

Install the SpecThis plugin marketplace and the starter plugin from any Claude Code session.

What you get

The SpecThis Claude Code marketplace is a public catalog of plugins SpecThis publishes for Claude Code. Add the marketplace once, then install (and later update) any plugin we ship from there.

Today the marketplace ships one starter plugin, hello-specthis, so you can verify the install path works end-to-end. Real plugins land in subsequent releases.

Repo: SpecThis-Open-Source/spec-this-claude-code-marketplace

Prerequisites

Install in two commands

1. Add the marketplace
claude plugin marketplace add SpecThis-Open-Source/spec-this-claude-code-marketplace

You should see specthis listed when you run claude plugin marketplace list.

2. Install the starter plugin
claude plugin install hello-specthis@specthis

Start a Claude Code session, then invoke the bundled skill:

/hello-world

You should see a SpecThis greeting confirming the install path is wired up.

Update

When a new release lands, refresh your local copy:

claude plugin marketplace update specthis

Each plugin's version comes from its plugin.json. Updates only flow when that version field changes — semantic-release does this automatically on every push to main.

Uninstall

claude plugin uninstall hello-specthis@specthis
claude plugin marketplace remove specthis

Troubleshooting

  • Marketplace not found: verify you typed the repo path exactly — SpecThis-Open-Source/spec-this-claude-code-marketplace. The repo is public; no GitHub auth is required to add it.
  • Plugin install fails with a manifest error: run claude plugin marketplace update specthis to refresh your local copy of the catalog, then try the install again.
  • Skill doesn't appear after install: restart your Claude Code session — skills are loaded at session start.
  • Email support@specthis.ai if anything is still off.
