When your agent uses it

Building public-facing pages
Adding title/description tags
Optimizing for search engines

Example prompts

“Use the seo-fundamentals skill to review SEO including meta tags, semantic HTML, and Open Graph”
“/seo-fundamentals”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Multiple H1 Tags
Missing Alt Text
Div Soup (No Semantic HTML)
Skipping Heading Levels
Generic Title Tags

What it can do on your machine

Read from SKILL.md and the folder at commit bd1f17c. 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 html and typescript).
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.

Context cost

SEO Fundamentals loads about 1.4k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 389 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~46
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k

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.

SEO Fundamentals Review

"Good SEO is good UX. If search engines can't understand your page, users might not find it."

When to Apply

Activate this skill when:

Reviewing HTML <head> sections
Seeing meta tags in code
Next.js/Remix page components
HTML structure with headings
Any page that should be indexed

Meta description — 150-160 characters, compelling
Single H1 — One per page, describes main content
Logical heading hierarchy — H1 → H2 → H3 (no skipping)

Should Have (Marketing Pages)

Performance (Affects SEO)

Core Web Vitals awareness
- LCP (Largest Contentful Paint) < 2.5s
- FID (First Input Delay) < 100ms
- CLS (Cumulative Layout Shift) < 0.1

Common Mistakes (Anti-Patterns)

1. Multiple H1 Tags

html

<!-- ❌ BAD: Multiple H1s confuse search engines -->
<h1>Welcome</h1>
<h1>Our Products</h1>
<h1>Contact Us</h1>

<!-- ✅ GOOD: One H1, logical hierarchy -->
<h1>Welcome to Our Store</h1>
<h2>Our Products</h2>
<h2>Contact Us</h2>

2. Missing Alt Text

html

<!-- ❌ BAD: Empty or useless alt -->
<img src="hero.jpg" alt="">
<img src="team.jpg" alt="image">

<!-- ✅ GOOD: Descriptive alt text -->
<img src="hero.jpg" alt="Software engineer working at laptop">
<img src="team.jpg" alt="Our founding team of 5 engineers">

3. Div Soup (No Semantic HTML)

html

<!-- ❌ BAD: No semantic meaning -->
<div class="header">
  <div class="nav">...</div>
</div>
<div class="content">...</div>
<div class="footer">...</div>

<!-- ✅ GOOD: Semantic HTML -->
<header>
  <nav>...</nav>
</header>
<main>...</main>
<footer>...</footer>

4. Skipping Heading Levels

html

<!-- ❌ BAD: Jumps from H1 to H4 -->
<h1>Page Title</h1>
<h4>Some Section</h4>

<!-- ✅ GOOD: Sequential hierarchy -->
<h1>Page Title</h1>
<h2>Main Section</h2>
<h3>Subsection</h3>

5. Generic Title Tags

html

<!-- ❌ BAD: Not descriptive -->
<title>Home</title>
<title>Page</title>

<!-- ✅ GOOD: Descriptive with keywords -->
<title>Daniel Lamb - Full Stack Developer Portfolio</title>
<title>Contact Us | Acme Software Solutions</title>

Socratic Questions

Ask these instead of giving answers:

Title: "If someone sees this title in Google results, would they click it?"
H1: "How many H1 tags does this page have? What happens if there are multiple?"
Alt Text: "If the image doesn't load, what information is lost?"
Semantic HTML: "Can a screen reader understand the structure of this page?"
Meta Description: "Does this description make you want to click?"

Stack-Specific Guidance

Next.js (App Router)

tsx

// Pattern: Metadata export
export const metadata = {
  title: 'Page Title',
  description: 'Page description',
  // Your implementation will differ
};

Next.js (Pages Router)

tsx

// Pattern: Next Head
import Head from 'next/head';

<Head>
  <title>Your title here</title>
  <meta name="description" content="Your description" />
</Head>

Plain HTML/React

html

<!-- In index.html or via react-helmet -->
<head>
  <title>Title here</title>
  <meta name="description" content="Description here">
</head>

Red Flags to Call Out

Missing title tag	"What will this page show in search results?"
Multiple H1s	"Which heading is the main topic? Search engines are confused."
No meta description	"How will Google summarize this page?"
Empty alt text	"What if the image doesn't load? What info is lost?"
All divs, no semantics	"Can a screen reader navigate this page?"
Title over 60 chars	"This will be cut off in search results. Can you shorten it?"

Open Graph Template

html

<!-- Minimum viable Open Graph -->

<meta property="og:description" content="Your page description">
<meta property="og:image" content="https://yoursite.com/og-image.jpg">
<meta property="og:url" content="https://yoursite.com/page">
<meta property="og:type" content="website">
