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 | $0.00046 | $0.01417 |
| Opus 5.5 | $0.00018 | $0.00567 |
| Sonnet 5.5 | $0.00009 | $0.00283 |
| Haiku 4.5 | $0.00005 | $0.00142 |
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 1mo 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.

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.

medusa-setup is a skill published in the GitHub repository OrcaQubits/agentic-commerce-skills-plugins (40 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 1,417 once invoked, about $0.0002 per session on Opus 5.5. 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.
