medusa-plugins is a skill for Claude Code from OrcaQubits/agentic-commerce-skills-plugins. It costs 39 tokens per session (1,421 once invoked), scanned C, original, MIT.

A guide to building Medusa v2 plugins, which are reusable packages that can add features such as data models, routes, workflows, event handlers, and admin code to multiple projects.

In plain words
What is it for?
Use it to create a plugin, configure its options, include Medusa components, package it as an npm package, and publish it for other projects.
Why use it?
It clarifies the difference between a project-specific module and a distributable plugin, making extensions easier to package and reuse.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

medusa-plugins scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Medusa v2 Plugin Development

Before writing code

Fetch live docs:

  1. Fetch https://docs.medusajs.com/learn/fundamentals/plugins for plugin overview
  2. Web-search site:docs.medusajs.com plugin vs module for comparison
  3. Web-search site:docs.medusajs.com create medusa plugin for plugin scaffolding
  4. Web-search site:docs.medusajs.com plugin options configuration for plugin options pattern
  5. Web-search site:docs.medusajs.com publish plugin npm for packaging and distribution

Plugin vs Module

Aspect Module Plugin
Scope Single concern (data + service) Full feature (modules + routes + workflows + admin)
Location src/modules/ in project Separate npm package
Distribution Not distributable Published to npm
Configuration Registered in modules array Registered in plugins array
Contains Models, service, loaders Modules, API routes, workflows, subscribers, admin, links
Use case Project-specific domain Reusable across projects

A plugin is essentially a packaged Medusa project that can contain all the same src/ directories.

Plugin Directory Structure

Directory Contents
src/modules/ Custom modules (models, services)
src/workflows/ Workflow definitions
src/api/store/, src/api/admin/ API routes + middlewares.ts
src/subscribers/ Event subscribers
src/admin/widgets/, src/admin/routes/ Admin UI extensions
src/links/ Module link definitions
Root package.json, tsconfig.json, README.md

A plugin mirrors the standard Medusa src/ directory structure — all conventions apply.

Plugin Definition

The plugin's package.json must include specific fields:

package.json Key Fields

Field Value Purpose
name medusa-plugin-my-feature npm package name
main ./dist/index.js Compiled entry point
types ./dist/index.d.ts TypeScript declarations
files ["dist", "!dist/**/*.map"] Included in npm package
keywords ["medusa-plugin"] Discoverability
peerDependencies @medusajs/framework Medusa version compatibility

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
