What it does
Structured Data is an agent skill from thedaviddias/Front-End-Checklist. 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.
Its SKILL.md is about 420 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 Technical SEO. 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 metadata
- Structured data
- Indexability related to Add structured data markup
Example prompts
- “/structured-data”
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
Structured Data loads about 420 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 156 words of instructions outside code blocks.
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 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,
