grida: Skill for Claude Code

.agents/skills/seo/SKILL.md

seo is a skill for Claude Code, Codex from gridaco/grida. It costs 126 tokens per session (2,028 once invoked), scanned A, original, Apache-2.0.

A set of search-visibility guidelines for Grida websites, blog posts, and documentation. SEO, or search-engine optimization, means structuring pages so search engines can understand and display them accurately.

In plain words
What is it for?
Adding Next.js metadata, Open Graph and Twitter cards, JSON-LD structured data, sitemaps, Docusaurus frontmatter, and image-search information to public pages.
Why use it?
It provides consistent rules for page metadata, social sharing previews, sitemaps, structured data, and image search details. This helps public content expose the information search engines need.

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

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 2mo 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.

Guidelines for search engine optimization across the Grida project -- Next.js pages, blog posts, and documentation.

Next.js Pages (editor/app/(www))

Metadata

Every public page must export metadata (static or dynamic).

// Static
export const metadata: Metadata = {
  title: "Page Title — Grida",
  description: "Concise, keyword-rich description under 160 chars.",
  keywords: ["relevant", "keywords"],
  openGraph: {
    title: "Page Title — Grida",
    description: "Same or tailored OG description.",
    images: ["/og/page-name.png"],
  },
  twitter: {
    card: "summary_large_image",
  },
};

// Dynamic
export async function generateMetadata({ params }): Promise<Metadata> { ... }

Rules:

  • title should end with — Grida (or use a title.template in the root layout).
  • description must be unique per page, under 160 characters, and include primary keywords.
  • Every page with OG images must set metadataBase or use absolute URLs so crawlers resolve them correctly.
  • OG images must return 200 without auth and use correct Content-Type.

metadataBase

When openGraph.images uses relative paths, the layout or page must set:

metadataBase: new URL("https://grida.co"),

Without this, crawlers may see broken OG URLs.

Sitemap

Public pages belong in editor/app/sitemap.ts.

{
  url: "https://grida.co/new-page",
  changeFrequency: "monthly",
  priority: 0.5,
}
  • Use priority: 1 only for the homepage.
  • Match changeFrequency to actual update cadence.
  • When adding a new public page, always add a sitemap entry.
  • Sitemaps are split per route group (root, /packages, /library, …). A new sitemap.ts is invisible to crawlers until it's added as a Sitemap: line in editor/app/robots.txt — non-root sitemaps are not auto-discovered.
  • Prefer deriving sitemap entries from the page's data source (see packages/sitemap.ts) over hand-maintained URL lists, which drift.

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.
