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 | $0.00039 | $0.01591 |
| Opus 5 | $0.00019 | $0.00796 |
| Sonnet 5 | $0.00008 | $0.00318 |
| Haiku 4.5 | $0.00004 | $0.00159 |
Grade A, and why
shopify-admin-agentic-image-alt-text 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 11d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
An AI shopping agent reads image alt text to understand a product's appearance — color, material, style, use. Blank or filename-style alt text ("IMG_2931.jpg") tells the agent nothing, so it can't match the product to a visual query ("red linen midi dress") or describe it to a shopper. This skill finds product images with missing or low-value alt text and writes concise, descriptive alt text derived from the product's title, options, type, and tags. Fixes the agentiq.report finding listing-image-alt-text.
Prerequisites
- Authenticated Shopify CLI session (
shopify auth login --store <domain>) - Required API scopes:
read_products,write_products,write_files
Parameters
All skills accept these universal parameters:
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| format | string | no | human | Output format: human (default) or json |
| dry_run | bool | no | false | Preview mutations without executing |
Skill-specific parameters:
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| collection_id | string | no | — | Limit to a collection GID |
| tag | string | no | — | Limit to a product tag |
| overwrite | bool | no | false | If true, also rewrite filename-style / placeholder alt text; if false, only fill blanks |
| max_chars | int | no | 125 | Alt-text length cap (accessibility + agent-readability) |
Safety
⚠️ Step 3 (
fileUpdate) writes alt text to live media. Withoverwrite: trueit replaces existing alt text, which is not bulk-reversible. Rundry_run: truefirst and review the proposed alt text per image. Default (overwrite: false) only fills blanks and is low-risk.
Workflow Steps
- OPERATION:
products— query Inputs:first: 250, optional collection/tag filter; fieldstitle,productType,tags,options,media{ MediaImage{ id image{ altText } } }; paginate until done. Expected output: Product media with current alt text + the product context needed to generate good alt text.
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.
