Plugin check: Run node "${PLUGIN_ROOT}/scripts/check-version.js" — if it outputs a message, show it to the user before proceeding.

Add SEO

Add essential SEO assets to a Power Pages code site: robots.txt, sitemap.xml, and meta tags.

Prerequisite: This skill expects an existing Power Pages code site created via /create-site. Run that skill first if the site does not exist yet.

Core Principles

• Crawlability first: Every public page must be discoverable by search engines via a valid robots.txt and sitemap.xml before any other SEO work matters.
• Accurate metadata: Meta tags (title, description, Open Graph) must truthfully represent page content — misleading metadata harms rankings.
• Framework-aware placement: SEO assets must be placed in the correct location for the detected framework (public directory, layout component, etc.).

Initial request: $ARGUMENTS

Workflow

1. Phase 1: Verify Site Exists → Locate the Power Pages project
2. Phase 2: Gather SEO Configuration → Site URL, pages, preferences
3. Phase 3: Plan & Approve → Present SEO additions inline, get user approval
4. Phase 4: Add robots.txt → Create robots.txt in public directory
5. Phase 5: Add sitemap.xml → Generate sitemap.xml from site routes
6. Phase 6: Add Meta Tags → Add title, description, viewport, Open Graph, and favicon to index.html
7. Phase 7: Verify & Commit → Verify via Playwright, commit changes

Phase 1: Verify Site Exists

Goal: Confirm a Power Pages code site exists and understand its structure.

Actions

1.1 Locate Project

Look for powerpages.config.json in the current directory or immediate subdirectories to find the project root. Use your file-search tool (e.g., Glob with patterns powerpages.config.json and */powerpages.config.json) rather than a shell-specific command.

If not found: Tell the user to create a site first with /create-site.

1.2 Read Existing Config

Read powerpages.config.json to get the site name and config.

1.3 Detect Framework & Discover Routes

Read package.json to determine the framework and locate key files. See ${PLUGIN_ROOT}/references/framework-conventions.md for the full framework → public directory → index HTML mapping and route discovery patterns.

Build a list of all routes (e.g., /, /about, /contact, /blog).

Output

• Project root path identified
• Framework detected (React, Vue, Angular, or Astro)
• Full list of discoverable routes

Phase 2: Gather SEO Configuration

Goal: Collect all SEO preferences from the user before making any changes.

Actions

Use AskUserQuestion to collect SEO preferences:

Call 1

Call 2

Output

• Production URL confirmed
• Exclusion list finalized
• Meta description text
• Open Graph tag preference (yes/no)

Phase 3: Plan & Approve

Goal: Present the full SEO plan to the user and get explicit approval before making changes.

Actions

Present the SEO additions that will be made as a clear, inline summary:

1. robots.txt content — which paths will be allowed/disallowed
2. sitemap.xml content — all discovered routes with the production URL and priority assignments
3. Meta tags to add to index.html — title, description, viewport, charset, Open Graph, Twitter Card
4. Favicon — link tag and placeholder SVG

🚦 Gate (plan · add-seo:3.plan-approval): Final sign-off on the SEO additions before any robots.txt / sitemap.xml / index.html write.

Trigger: Phase 3 has presented the full plan inline (robots.txt, sitemap.xml, meta tags, favicon). Why we ask: SEO assets land on disk with the wrong production URL, wrong exclusions, or unwanted OG tags — fixable but noisy in git history. Cancel leaves: Nothing — no file writes yet.

After presenting the plan, use AskUserQuestion to get approval:

If the user chooses "I'd like to make changes", ask what they want to change, update the plan accordingly, and present the revised plan for approval again.

Output

• User-approved SEO plan ready for implementation

Phase 4: Add robots.txt

Goal: Create a valid robots.txt that tells search engines which pages to crawl.

Actions

Create robots.txt in the public directory (<PROJECT_ROOT>/public/robots.txt):

User-agent: *
Allow: /

Sitemap: <PRODUCTION_URL>/sitemap.xml

If the user specified pages to exclude, add Disallow directives:

User-agent: *
Allow: /
Disallow: /admin/
Disallow: /auth/

Sitemap: <PRODUCTION_URL>/sitemap.xml

Output

• public/robots.txt created with correct directives

Phase 5: Add sitemap.xml

Goal: Generate a complete sitemap.xml listing all discoverable routes with proper priorities.

Actions

Create sitemap.xml in the public directory (<PROJECT_ROOT>/public/sitemap.xml).

Generate entries for each discovered route using the production URL:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc><PRODUCTION_URL>/</loc>
    <lastmod><TODAY_DATE></lastmod>
    <changefreq>weekly</changefreq>
    <priority>1.0</priority>
  </url>
  <url>
    <loc><PRODUCTION_URL>/about</loc>
    <lastmod><TODAY_DATE></lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
  <!-- Additional routes... -->
</urlset>

Priority rules:

• Home page (/): 1.0
• Top-level pages: 0.8
• Sub-pages: 0.6

Exclusions: Do not include routes the user chose to exclude (e.g., /admin/*, /auth/*).

Output

• public/sitemap.xml created with all routes, correct URLs, and no placeholders

Phase 6: Add Meta Tags

Goal: Add comprehensive meta tags, Open Graph tags, and a favicon to the site's HTML.

Actions

6.1 Essential Meta Tags

Add or update meta tags in the site's index.html (location depends on framework — see Phase 1.3):

<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title><SITE_TITLE></title>
  <meta name="description" content="<META_DESCRIPTION>" />
  <meta name="robots" content="index, follow" />
  <link rel="canonical" href="<PRODUCTION_URL>/" />
  <link rel="sitemap" type="application/xml" href="/sitemap.xml" />
</head>

6.2 Open Graph Tags (if user opted in)

Add Open Graph and Twitter Card meta tags inside <head>:

<!-- Open Graph -->
<meta property="og:type" content="website" />
<meta property="og:title" content="<SITE_TITLE>" />
<meta property="og:description" content="<META_DESCRIPTION>" />
<meta property="og:url" content="<PRODUCTION_URL>/" />
<meta property="og:site_name" content="<SITE_TITLE>" />

<!-- Twitter Card -->
<meta name="twitter:card" content="summary" />
<meta name="twitter:title" content="<SITE_TITLE>" />
<meta name="twitter:description" content="<META_DESCRIPTION>" />

6.3 Favicon

Check if a favicon already exists in the public directory. If not, add a simple SVG favicon link:

<link rel="icon" type="image/svg+xml" href="/favicon.svg" />

Create a minimal placeholder public/favicon.svg using the site's primary color:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100">
  <rect width="100" height="100" rx="20" fill="<PRIMARY_COLOR>"/>
  <text x="50" y="70" font-size="50" text-anchor="middle" fill="white" font-family="system-ui, sans-serif" font-weight="bold"><FIRST_LETTER></text>
</svg>

Where <FIRST_LETTER> is the first letter of the site name and <PRIMARY_COLOR> is the primary theme color from the site's configuration.

6.4 Astro-Specific Handling

For Astro sites, meta tags should be added to the base layout component (e.g., src/layouts/Layout.astro) rather than a root index.html. Astro uses component-based <head> management.

Output

• Meta tags added to index.html (or Astro layout equivalent)
• Open Graph and Twitter Card tags added (if opted in)
• Favicon SVG created and linked (if not already present)

Phase 7: Verify & Commit

Goal: Confirm all SEO assets are in place, verify via Playwright, and commit changes.

Actions

7.1 Verify Files Exist

Confirm the following files were created/updated:

• public/robots.txt
• public/sitemap.xml
• public/favicon.svg (if created)
• index.html or equivalent (meta tags added)

7.2 Verify via Playwright

If a dev server is running (or start one):

1. Navigate to the site root and use browser_snapshot to verify meta tags are present in the page source
2. Navigate to /robots.txt and verify it loads
3. Navigate to /sitemap.xml and verify it loads

7.3 Record Skill Usage

Reference: ${PLUGIN_ROOT}/references/skill-tracking-reference.md

Follow the skill tracking instructions in the reference to record this skill's usage. Use --skillName "AddSeo".

7.4 Git Commit

CRITICAL — This step is MANDATORY. You MUST commit the SEO changes before finishing. Do NOT skip this step.

Stage the specific SEO files and commit:

git add public/robots.txt public/sitemap.xml public/favicon.svg index.html
git commit -m "Add SEO: robots.txt, sitemap.xml, meta tags, favicon"

Adjust the file paths based on what was actually created (e.g., include src/layouts/Layout.astro instead of index.html for Astro sites, omit favicon.svg if it was not created). Only stage files that were created or modified by this skill.

7.5 Present Summary

Present a summary of what was added:

7.6 Suggest Next Steps

After the summary, suggest:

• Deploy the site to make SEO changes live: /deploy-site
• If data model is needed: /setup-datamodel
• For more advanced SEO: consider structured data (JSON-LD), performance optimization, and accessibility audit

Output

• All files verified on disk
• Playwright verification passed
• Git commit created with all SEO changes

Important Notes

Progress Tracking

Use TaskCreate at the start to track each phase:

Update each task with TaskUpdate as it is completed.

Key Decision Points

• Phase 1: If powerpages.config.json is not found, stop and redirect the user to /create-site.
• Phase 2: If the user specifies custom exclusions, confirm the exact paths before proceeding.
• Phase 3: Do not proceed to implementation until the user explicitly approves the plan.
• Phase 6.4: If the framework is Astro, meta tags go into the layout component, not index.html.
• Phase 7.2: If Playwright verification fails (e.g., robots.txt does not load), diagnose and fix before committing.
