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 | $0.00037 | $0.01830 |
| Opus 5 | $0.00018 | $0.00915 |
| Sonnet 5 | $0.00007 | $0.00366 |
| Haiku 4.5 | $0.00004 | $0.00183 |
Grade A, and why
shopify-admin-bundle-availability-check 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 10d 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 — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Walks every product flagged as a bundle (either via Shopify's native requiresComponents mechanic or a bundle.components metafield convention), then verifies each component variant has sufficient inventory to back the bundle's quantity ratio. Surfaces bundles that are listed as in-stock on the storefront but cannot actually be fulfilled because one component has run out. Read-only — no mutations.
Prerequisites
- Authenticated Shopify CLI session:
shopify store auth --store <domain> --scopes read_products,read_inventory - API scopes:
read_products,read_inventory
Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| metafield_namespace | string | no | bundle | Metafield namespace where bundle component definitions live |
| metafield_key | string | no | components | Metafield key that holds the JSON list of {variantId, quantity} |
| safety_stock | integer | no | 0 | Treat component as out-of-stock if on-hand minus this buffer is below required |
| only_listed | bool | no | true | Only check bundle products with status ACTIVE |
| format | string | no | human | Output format: human or json |
Safety
ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. The skill reads inventory and metafields only; it never adjusts component quantities or bundle availability.
Workflow Steps
-
OPERATION:
products— query Inputs:first: 250,query: "metafield:<namespace>.<key>:* OR product_type:bundle", selectrequiresSellingPlan,status,metafield(namespace, key),variants, pagination cursor Expected output: Bundle products and their parent variants; paginate untilhasNextPage: false -
For each bundle, parse component list. Native bundles use
productVariant.requiresComponentsandproductVariant.productVariantComponents. Metafield bundles parse JSON value into[{variantId, quantity}].
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.
