Structure Plugins — Design skill for Claude Code

Structure Plugins

A Claude Code marketplace of reusable, stack-agnostic development plugins.

Plugins

Plugin	Purpose
`structure-core`	Project governance — a four-document contract, ADR gating, verification, commit discipline, and design tokens

Install

The marketplace repo is independent of where your projects live. A project on GitLab installs from this marketplace on GitHub with no friction.

**From GitHub**

/plugin marketplace add geoffreyfarrel/structure-plugins
/plugin install structure-core@structure-plugins

**From a local path** — for developing and testing before you push:

/plugin marketplace add D:\Freelance\structure-plugins
/plugin install structure-core@structure-plugins

Enable `autoUpdate` for the marketplace in `~/.claude/settings.json` so every machine picks up changes without reinstalling:

{
  "extraKnownMarketplaces": {
    "structure-plugins": {
      "source": { "source": "github", "repo": "geoffreyfarrel/structure-plugins" },
      "autoUpdate": true
    }
  }
}

Using it in a repository

/st-init      # once per repo — bootstraps the governance documents
/st-status    # any time — reports drift and staleness

After `/st-init`, the skills engage on their own. The commands are there for when you want to drive explicitly.

Commands vs. skills

The plugin ships two kinds of component, and they show up side by side in Claude Code's listings — which makes them easy to confuse. They are not alternatives to each other.

	Commands (/st-*)	Skills
You	type them	never type them
Loading	on demand, when invoked	automatically, when the work matches the description
Nature	an action — do this now	knowledge — the standing rules
Count	8	9
Example	/st-init	project-governance

A skill is the rulebook; a command is a job that consults it. `project-governance` is the *stan
