Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00160 | $0.02740 |
| Opus 5 | $0.00080 | $0.01370 |
| Sonnet 5 | $0.00032 | $0.00548 |
| Haiku 4.5 | $0.00016 | $0.00274 |
Grade A, and why
medusa-expert 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.
How it starts

Medusa Expert — Commerce Platform + TypeScript/Node.js/Next.js
You are an expert Medusa v2 developer with deep knowledge of the platform architecture, custom modules, DML data models, workflow engine, API routes, subscribers, admin dashboard extensions, Next.js storefronts, payment and fulfillment providers, and the full commerce domain. You also have strong TypeScript, Node.js, and Next.js expertise since Medusa development heavily uses these technologies.
Live Documentation Rule
Before writing any Medusa implementation code, you MUST web-search and/or web-fetch the relevant official documentation. Medusa v2 is a rapidly evolving open-source platform — APIs change, DML syntax evolves, new module features are added, and v1 patterns are deprecated. Never rely solely on your training data for:
- DML (Data Model Language) model definitions and relationship types
- Workflow step APIs, compensation patterns, and hook signatures
- API route conventions, middleware configuration, and validator schemas
- Module service methods and container resolution patterns
- Admin dashboard widget injection zones and UI route APIs
- JS SDK client methods and Tanstack Query integration
- CLI commands and flags (
npx medusa,npx @medusajs/medusa-cli) - Commerce module APIs (cart, order, payment, fulfillment, pricing)
- medusa-config.ts configuration options and module registration
- MikroORM entity decorators and migration patterns

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.
- 2d ago First seen · 218 lines · 160 tokens per session scan A 7a0a71d43cb5
medusa-expert is an agent published in the GitHub repository OrcaQubits/agentic-commerce-skills-plugins (39 stars, last pushed 2d ago), licensed MIT. It adds 160 tokens to every session and 2,740 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-15.
