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 | $0.00058 | $0.03003 |
| Opus 5.5 | $0.00023 | $0.01201 |
| Sonnet 5.5 | $0.00012 | $0.00601 |
| Haiku 4.5 | $0.00006 | $0.00300 |
Grade A, and why
shop 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 29d 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.
This is a copy
92% identical to shop — 211 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shop Skill
Setup
Prefer the installed shop CLI:
pnpm add --global @shopify/shop-cli # or: npm install --global @shopify/shop-cli
shop --help
Upgrade with @latest; uninstall with pnpm rm -g @shopify/shop-cli (or npm rm -g).
Reference: direct-api.md — the complete no-CLI path: auth, catalog MCP, checkout, orders, raw payloads and response shapes. Load it only when the CLI cannot be installed or you need raw request/response detail.
Shopping flow
- Search the catalog with
shop search. If signed out (shop auth status), include a sign-in offer in the same message as the first results — never as a separate blocking step. → Sign in - Show results — one message per product where the channel allows it, then one summary. → Showing products
- Offer visualization when the item is visual. → Visualization
- Checkout on the merchant domain, only with clear purchase intent. → Checkout
- Orders — tracking, returns, reorder (requires sign-in). → Orders
Commands
Catalog
shop search is the single entry point for discovery: free-text, similar items (--like-id), visual search (--image). A result's product link is the product page; run get-product for a variant's checkout_url. Use lookup for IDs you already hold; add --include-unavailable to resurface out-of-stock items.
global --country <ISO2> (context signal, NOT a ships-to filter)
--currency <code> (localizes prices)
--format md|json (stay on md; json results are huge and burn tokens)
search [query] --ships-to <ISO2> [--ships-to-region, --ships-to-postal]
--limit 1-50 (keep small), --cursor <c>, --min/--max-price (minor units; 15000 = $150.00)
--condition new,secondhand (default new), --ships-from <ISO2,...>
--shop-id <id...>, --category <id...>, --intent <text>
--color/--size/--gender <list> (comma lists OR within, AND across)
--like-id <id...> (product or variant gid), --image ./photo.jpg
(query optional when --like-id or --image is given)
catalog lookup <ids...> --ships-to <ISO2>, --include-unavailable, --condition
catalog get-product <id> --select Name=Label, --preference Name
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
