At a glance

A skill your agent uses when auditing e-commerce product pages or implementing structured data for a shop.

  • Auditing e-commerce product pages
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Implementing structured data for a shop

What it does

Product is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing e-commerce product pages or implementing structured data for a shop. Applies to any page selling or describing a specific product.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Marketing & SEO, covering Schema markup and E-commerce operations. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Auditing e-commerce product pages
  • Implementing structured data for a shop

Example prompts

  • “/product”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    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.

Context cost

Product loads about 592 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 260 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~592
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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.

Add Product schema markup

Product schema enables Google to show price, availability, ratings, and review count directly in search results—rich results have significantly higher click-through rates than standard blue links.

Quick Reference

  • Add Product JSON-LD schema to every product page for rich result eligibility
  • Required for rich results: name, image, description, and offers (with price and priceCurrency)
  • Include aggregateRating for star ratings in search results
  • Prices in schema must match the prices displayed on the page

Check

Check each product page for a JSON-LD script block with @type 'Product'. Verify it includes: name, image, description, and an offers property with price, priceCurrency, and availability. Check that prices in schema match the visible page prices. Validate with Google's Rich Results Test.

Fix

Add a Product JSON-LD block to each product page. Required: name, image (array of URLs), description, offers.price, offers.priceCurrency, offers.availability. Recommended: aggregateRating (ratingValue, reviewCount), brand, sku, gtin13/gtin8/mpn.

Explain

Product structured data enables Google Shopping-style rich results in organic search, showing price, star ratings, and stock status directly in the SERP. These rich results have higher visual prominence and click-through rates. Without schema, Google can only show a plain blue link for your product pages.

Code Review

Find JSON-LD blocks with @type 'Product'. Verify required fields: name, image (must be absolute URL array), description, offers.price (numeric), offers.priceCurrency (ISO 4217 code), offers.availability (schema.org URL). Check that offers.price matches the visible price on the page. Validate that aggregateRating.reviewCount > 0 if rating is present. Run through Google's Rich Results Test.
