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.

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 | $0.01894 |
| Opus 5 | $0.00017 | $0.00947 |
| Sonnet 5 | $0.00007 | $0.00379 |
| Haiku 4.5 | $0.00003 | $0.00189 |
Grade A, and why
shopify-admin-discount-cost-trend 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 13d 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
The opening of the file, as written. The whole thing — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Tracks how much money the store gave away in discounts over time, bucketed by week, month, or quarter, and broken down by discount code and discount type (percentage / fixed amount / free shipping / automatic). Answers: "is our discount spend trending up or down, and which campaigns are driving it?" Read-only — no mutations. Complements discount-roi-calculator (per-discount return) with a longitudinal view of total cost.
Prerequisites
- Authenticated Shopify CLI session:
shopify store auth --store <domain> --scopes read_orders - API scopes:
read_orders
Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| period | string | no | month | Bucket size: week, month, or quarter |
| periods_back | integer | no | 12 | Number of buckets to report |
| top_codes | integer | no | 10 | Top discount codes to break out individually; remainder grouped as other |
| include_shipping_discounts | bool | no | true | Whether to count shipping discounts in the totals |
| format | string | no | human | Output format: human or json |
Safety
ℹ️ Read-only skill — no mutations are executed. Safe to run at any time.
Workflow Steps
-
Compute window from
period×periods_back(e.g.,month× 12 → last 12 calendar months starting from the first day of the bucket 11 months ago) -
OPERATION:
orders— query Inputs:query: "created_at:>='<window_start>' financial_status:paid",first: 250, selectcreatedAt,discountCodes,currentTotalDiscountsSet,totalDiscountsSet,cartDiscountAmountSet,discountApplications { allocationMethod, targetType, value, ... on DiscountCodeApplication { code }, ... on AutomaticDiscountApplication { title }, ... on ManualDiscountApplication { title } },shippingLines { discountAllocations { allocatedAmountSet } }, pagination cursor Expected output: All paid orders in the window with discount data; paginate untilhasNextPage: false
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.
