structured-data

Structured Data is an Agent Skill for business published in the thedaviddias/Front-End-Checklist repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when auditing metadata, crawlability, structured data, or indexability related to Add structured data markup. Verify the rendered HTML and HTTP response rather than relying only on source files.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/thedaviddias/Front-End-Checklist/blob/HEAD/skills/structured-data/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/structured-data, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Add structured data markup

Structured data enables rich snippets with stars, prices, images, and FAQ dropdowns in search results—significantly increasing click-through rates.

Quick Reference

  • Structured data enables rich snippets in search results
  • Use JSON-LD format (Google recommended)
  • Common types: Article, Product, FAQ, HowTo, LocalBusiness
  • Validate with Google Rich Results Test

Check

Analyze if this webpage implements structured data using Schema.org vocabulary. Check for JSON-LD, Microdata, or RDFa markup.

Fix

Add appropriate Schema.org structured data to this webpage based on its content type (Article, Product, LocalBusiness, etc.).

Explain

Explain how structured data helps search engines understand page content and enables rich snippets in search results.

Code Review

Review metadata generation, rendered HTML, structured data, and response headers related to Add structured data markup. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.

For full implementation details, code examples, and framework-specific guidance, see references/rule.md.
