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 A, and why

medusa-setup scanned grade A with 0 findings 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Medusa v2 Development Setup

Before writing code

Fetch live docs:

  1. Fetch https://docs.medusajs.com/learn/installation for installation guide
  2. Web-search site:docs.medusajs.com create medusa starter for project scaffolding
  3. Web-search site:docs.medusajs.com medusa-config reference for configuration options
  4. Web-search site:docs.medusajs.com project directory structure for v2 layout

Prerequisites

Required Software

Software Minimum Version Purpose
Node.js v20+ Runtime
PostgreSQL — (see docs) Primary database
Redis v6+ Event bus, caching (optional for dev)
Git any Version control
npm / yarn / pnpm latest Package manager

PostgreSQL Setup

  • Create a dedicated database: CREATE DATABASE medusa_db;
  • Create a user with full privileges on that database
  • Connection string format: postgres://user:password@localhost:5432/medusa_db

Redis Setup (Optional for Development)

  • Default connection: redis://localhost:6379
  • Required in production for the event bus module and caching
  • In development, Medusa falls back to an in-memory event bus

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.
