Best practices for building commerce applications with Medusa v2, the headless e-commerce framework. Use when defining Medusa data models, writing workflows and steps with the Workflow SDK, creating API routes or subscribers, building module services that extend MedusaService, throwing MedusaError, or customizing the Medusa admin dashboard.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Medusa Development

Medusa is a headless commerce framework built around modules, data models, and workflows; almost every piece of business logic — from an API route to a scheduled job — should be expressed as a workflow made of discrete, composable steps.

## Workflow for Building a Medusa Feature

1. **Define or extend the data model** — Use the `model` utility from `@medusajs/framework/utils` to declare the module's data model(s) under `src/modules/<module>/models/`.
2. **Write the module service** — Create a service in `src/modules/<module>/service.ts` that extends `MedusaService` when the module has data models, exposing async methods for domain operations.
3. **Register the module** — Add the module to `medusa-config.ts` so Medusa's container can resolve it.
4. **Build steps** — Define each unit of work as a step with `createStep` from `@medusajs/framework/workflows-sdk`, including a compensation function for anything that needs to be undone on failure.
5. **Compose the workflow** — Wire steps together with `createWorkflow`, using `transform` for data shaping and `when` for conditional branches.

How to install

The exact contents, by fingerprint
mdr add mindrally/skills/medusa-development@sha256:56fba24d2522509f

The line at the top of this page pins the label git:20261008.7682ca7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
