Structured data

What it does

Schema Markup is an agent skill from mohitagw15856/pm-claude-skills. Generate structured-data (Schema.org / JSON-LD) markup to win rich results in search. Use when asked about schema markup, structured data, rich snippets, JSON-LD, or making a page eligible for stars/FAQ/breadcrumb results. Produces valid JSON-LD for the right schema type, the rich-result it targets, required vs. recommended fields, and validation/guideline notes.

Its SKILL.md is about 840 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Schema markup. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. 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 (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- schema.org
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

Schema Markup loads about 838 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 397 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~95
When it runs · the whole SKILL.md, loaded when a task matches: ~838

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.

name: schema-markup
description: Generate structured-data (Schema.org / JSON-LD) markup to win rich results in search. Use when asked about schema markup, structured data, rich snippets, JSON-LD, or making a page eligible for stars/FAQ/breadcrumb results. Produces valid JSON-LD for the right schema type, the rich-result it targets, required vs. recommended fields, and validation/guideline notes.

Schema Markup Skill

Structured data tells search engines exactly what a page is — a product, a recipe, an FAQ, an event — making it eligible for rich results (star ratings, FAQ drop-downs, breadcrumbs) that win clicks. This skill produces valid JSON-LD for the right Schema.org type, with the fields Google actually requires, and flags the guideline traps that get markup ignored or penalised.

Required Inputs

Ask for these only if they aren't already provided:

The page & its content — what the page is (product, article, FAQ, local business, event, recipe, how-to…).
The rich result you want — e.g. review stars, FAQ accordion, breadcrumbs, sitelinks, event listing.
The data — the actual values (name, price, rating, dates, Q&As) — markup must match visible content.

Output Format

Schema markup: [type] for [page]

Target rich result — which Google rich result this enables, and the eligibility note (e.g. review snippets need real, visible reviews).

Schema type — the correct Schema.org type (and any nesting, e.g. Product → AggregateRating + Offer).

JSON-LD — ready to paste in a <script type="application/ld+json"> block:

json

{
  "@context": "https://schema.org",
  "@type": "...",
  "...": "..."
}

Use the real provided values; mark any placeholders clearly.

Required vs. recommended fields — what Google requires for the rich result vs. nice-to-have, so nothing essential is missing.

Validation & guidelines — test in Google's Rich Results Test + Schema validator; the key rules: markup must reflect visible page content, no fake/marked-up-but-hidden data, no review spam (no self-serving aggregate ratings without real reviews). Note anything that would disqualify it.

Show full SKILL.md (165 more words)Show less

Quality Checks

The schema type matches the page content and the intended rich result
The JSON-LD is valid (proper @context/@type, correct nesting) and uses real values
All Google-required fields for that rich result are present
Markup reflects content actually visible on the page — no hidden or fabricated data
Validation steps and the relevant structured-data guidelines are noted

Anti-Patterns

Do not mark up content that isn't visible on the page — Google treats that as spam
Do not fabricate ratings/reviews or self-apply AggregateRating without real reviews
Do not omit required fields — the rich result simply won't trigger
Do not use the wrong type (e.g. Product for an article) — it won't validate
Do not ship without validating in the Rich Results Test

Based On

Schema.org structured data + Google's structured-data guidelines for rich results (JSON-LD, required fields, content-match rules).

Example Trigger Phrases

"Add schema markup to this page."
"Write JSON-LD for our product pages."
"Get rich snippets for our FAQ."
"Make this page eligible for star ratings in search."
