What it does

Shopify Admin Agentic Image Alt Text is an agent skill from 40RTY-ai/shopify-admin-skills. Generate and set descriptive alt text on product images so AI agents (which can't 'see' pixels) can understand and recommend what each product looks like.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI

It sits in Marketing & SEO. It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.

When your agent uses it

  • Marketing & SEO work in your project

Example prompts

  • “/shopify-admin-agentic-image-alt-text”

Requirements

  • Compatibility (from SKILL.md): Claude Code, Cursor, Codex, Gemini CLI

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. OPERATION: products — query
  2. COMPUTE (no API): for each image with blank (or, if overwrite, placeholder) alt text, compose alt text from title + relevant option values…
  3. OPERATION: fileUpdate — mutation

What it can do on your machine

Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • shopify

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code, Cursor, Codex, Gemini CLI

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Admin Agentic Image Alt Text loads about 1.6k tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 507 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

listing-image-alt-text

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:

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
formatstringnohumanOutput format: human (default) or json
dry_runboolnofalsePreview mutations without executing

Skill-specific parameters:

ParameterTypeRequiredDefaultDescription
collection_idstringno—Limit to a collection GID
tagstringno—Limit to a product tag
overwriteboolnofalseIf true, also rewrite filename-style / placeholder alt text; if false, only fill blanks
max_charsintno125Alt-text length cap (accessibility + agent-readability)

Safety

⚠️ Step 3 (fileUpdate) writes alt text to live media. With overwrite: true it replaces existing alt text, which is not bulk-reversible. Run dry_run: true first and review the proposed alt text per image. Default (overwrite: false) only fills blanks and is low-risk.

Workflow Steps

  1. OPERATION: products — query Inputs: first: 250, optional collection/tag filter; fields title, 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.

  2. COMPUTE (no API): for each image with blank (or, if overwrite, placeholder) alt text, compose alt text from title + relevant option values (color/material/style) + product type, trimmed to max_chars. Emit a preview table (image id → proposed alt).

  3. OPERATION: fileUpdate — mutation Inputs: files: [{ id: <MediaImage id>, alt: <generated alt> }] in batches (≤ 25). Expected output: Updated files; collect userErrors.

Session Tracking

Claude MUST emit the following output at each stage. This is mandatory.

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: <skill name>                         ║
║  Store: <store domain>                       ║
║  Started: <YYYY-MM-DD HH:MM UTC>             ║
╚══════════════════════════════════════════════╝

After each step, emit:

[N/TOTAL] <QUERY|MUTATION>  <OperationName>
          → Params: <brief summary of key inputs>
          → Result: <count or outcome>

If dry_run: true, prefix every mutation step with [DRY RUN] and do not execute it.

On completion, emit:

For format: human (default):

══════════════════════════════════════════════
OUTCOME SUMMARY
  <Metric label>:   <value>
  Errors:           0
  Output:           <filename or "none">
══════════════════════════════════════════════

For format: json, emit:

  "store": "<domain>",
  "started_at": "<ISO8601>",
  "completed_at": "<ISO8601>",
  "dry_run": false,

    }
  ],
  "outcome": {
    "metric_key": 0,
    "errors": 0,
    "output_file": null
  }
}

Output Format

human: count of images updated + a CSV (product, image_id, old_alt, new_alt). json: { images_updated, images_skipped, errors, output_file }.

Error Handling

ErrorCauseRecovery
THROTTLEDAPI rate limitWait 2s, retry up to 3 times
userErrors non-emptyInvalid file id / not a MediaImageLog message, skip, continue
Alt exceeds limitGenerated text too longTrim to max_chars at a word boundary

Best Practices

  • Lead the alt text with the concrete noun + distinguishing attribute ("Charcoal merino crew-neck sweater"), not marketing fluff — that's what agents match on.
  • Keep overwrite: false for the first pass to fix the worst gap (blanks) safely; do a reviewed overwrite: true pass later for filename-style alts.
  • Don't keyword-stuff — one accurate sentence beats a comma salad and reads better for screen-reader users too.
  • Re-run shopify-admin-agentic-readiness-audit afterward to confirm the alt-text coverage pillar moved.
