astro-seo

A set of search-engine optimization instructions for Astro websites. SEO means improving a site so search engines can understand and display its pages, while Open Graph controls how links appear when shared.

In plain words
What is it for?
Use it to configure metadata, social previews, structured data, sitemaps, RSS feeds, robots.txt, canonical URLs, language links, and Core Web Vitals for an Astro site.
Why use it?
It helps avoid missing page metadata, structured information, sitemap settings, canonical links, or multilingual signals that affect search results and sharing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

astro-seo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Does not cover locale routing mechanics beyond hreflang tag generation (astro-i18n), Content Layer schema design (astro-content), or image-specific optimization like <Image />/<Picture /> (astro-assets) — those are separate skills.

Astro SEO

Complete SEO strategy for Astro 7 sites — zero JS by default makes Astro naturally SEO-friendly.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

  1. fuse-ai-pilot:explore-codebase - Analyze existing layouts, head components, and metadata
  2. fuse-ai-pilot:research-expert - Verify latest SEO best practices via Context7/Exa
  3. mcp__context7__query-docs - Check Astro 7 sitemap/RSS integration docs

After implementation, run fuse-ai-pilot:sniper for validation.


Overview

When to Use

  • Adding meta tags and Open Graph to any Astro page
  • Generating JSON-LD structured data for rich snippets
  • Setting up @astrojs/sitemap for search indexing
  • Configuring RSS feeds with @astrojs/rss
  • Creating robots.txt and canonical URL patterns
  • Adding hreflang for multilingual SEO
  • Measuring and improving Core Web Vitals

Why Astro for SEO

Feature Benefit
Zero JS by default Pure HTML for crawlers, instant indexing
Static output Sub-second TTFB, top Core Web Vitals
Astro.site Canonical URL construction built-in
Islands Architecture Only hydrate interactive parts

Core Concepts

Head Component Pattern

Create a reusable <SEO /> or <Head /> component accepting title, description, og, canonical props. Place in all layouts. Use Astro.site for absolute URL construction.

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
