A local-development guide for a reorder plugin connected to a Medusa online-store backend and subscription storefront. It describes syncing changed plugin code, starting both services, and checking that the backend is ready.

Use it to sync plugin changes, start the Medusa backend and storefront as background tasks, and wait for the backend health check before testing.

It provides a repeatable way to bring the related local projects up together. It also avoids rebuilding the plugin when you only need to restart the services.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.00762
Opus 5.5	$0.00014	$0.00305
Sonnet 5.5	$0.00007	$0.00152
Haiku 4.5	$0.00003	$0.00076

Security

Grade A, and why

local-dev scanned grade A 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 2mo 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.

Local development in Medusa backend & Storefront

This skill describes how to sync local changes in the reorder plugin with an external Medusa backend and run both the Medusa backend and the subscription storefront as separate Antigravity background tasks.

Workflow Execution Steps for Agents

When requested to run /local-dev or start the local development environment:

Step 1: Initial Sync or Plugin Rebuild (Only when code changed)

If you modified the reorder plugin code and need to rebuild and push changes to yalc:

./.agents/scripts/sync-local-env.sh

[!NOTE] If the user simply requests to restart or start the backend/storefront without code changes, do NOT run sync-local-env.sh. Skip directly to Step 2 and restart the process.

Step 2: Start Medusa Backend (Background Task)

Start the Medusa backend dev server using run_command with IsDaemon: true and working directory set to the backend directory (Cwd: /Users/tomaszkasperski/Desktop/Development/medusa-reorder/my-medusa-store):

yarn dev

Step 3: Wait for Backend Readiness

Poll http://localhost:9000/health until the backend responds with HTTP 200 OK before starting the storefront:

until curl -s -f http://localhost:9000/health >/dev/null 2>&1; do sleep 1; done

Step 4: Start Subscription Storefront (Background Task)

Start the storefront dev server as a separate background daemon task using run_command with IsDaemon: true and working directory set to the storefront directory (Cwd: /Users/tomaszkasperski/Desktop/Development/medusa-reorder/subscription-storefront):

yarn dev

Step 5: Report URLs to the User

Always immediately provide the clickable URLs:

Medusa Backend API: http://localhost:9000
Medusa Admin Dashboard: http://localhost:9000/app
Subscription Storefront: http://localhost:8000

Manual Setup & Storefront Connection Requirements

1. Medusa Backend

Install yalc globally if needed: npm i yalc -g
In the Medusa backend's package.json, declare the plugin dependency using yalc:
```
"@reorderjs/reorder": "file:.yalc/@reorderjs/reorder"
```
Ensure the plugin is registered in medusa-config.ts.
Ensure PostgreSQL database is running and DATABASE_URL is configured in .env.
Ensure CORS settings in backend .env allow storefront access (STORE_CORS=http://localhost:8000,...).

What this file has done since we first saw it

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.

local-dev is a skill published in the GitHub repository reorder-js/reorder (59 stars, last pushed 12d ago), licensed MIT. It adds 35 tokens to every session and 762 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
