information-architecture-seo

information-architecture-seo is a skill for Codex from sergekostenchuk/seo-llm-skill-cluster. It costs 94 tokens per session (900 once invoked), scanned A, original, MIT.

A planning tool for organizing a website's pages, URLs, languages, and search-engine rules. It distinguishes roles such as topic pages, news articles, blogs, projects, and main reference pages.

In plain words
What is it for?
Use it to design URL patterns, page categories, canonical URLs, language groups, and whether pages should be indexed by search engines.
Why use it?
It prevents duplicate pages and unclear ownership, while defining which URL should be treated as the main version and how translated versions relate.

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

information-architecture-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 12d 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.

Information Architecture SEO

Use this skill after semantic-core-architect and before internal linking, schema, or LLM-readable layers.

Read references/url-architecture.md before producing a full URL map.

Owns

  • URL strategy;
  • page taxonomy;
  • page roles and content ownership;
  • canonical model;
  • hreflang groups;
  • index/noindex policy;
  • pillar/topic/news/article/blog/project role separation;
  • duplicate-content prevention.

Does Not Own

  • semantic core creation;
  • final page copy;
  • internal link graph details;
  • JSON-LD implementation;
  • rendered UI design;
  • external backlinks.

Workflow

  1. Read the semantic core, entity-topic map, site constraints, languages, and content model.
  2. Identify the canonical page role for each cluster/entity/topic.
  3. Define route patterns before individual URLs.
  4. Set canonical policy per page role.
  5. Define hreflang groups for localized equivalents.
  6. Mark page status: planned, draft, published, noindex, or deferred.
  7. Record duplicate-content risks and ownership boundaries.
  8. Produce url-map.yaml using assets/url-map.template.yaml.
  9. Hand off to internal-link-graph-architect and technical-seo-schema-engineer.

Canonical Rules

  • A page can be self-canonical when it has a distinct user/search role and visible content.
  • A short news brief and one expanded longform article can both be self-canonical when the brief is the fast news surface and the longform is the durable explanation surface.
  • Do not canonicalize a standalone brief to its longform by default.
  • Do not create extra public story variants beyond the declared model.
  • Topic and pillar pages must summarize and organize; they must not duplicate article bodies.
  • Locale alternates use hreflang; they do not replace canonical self-reference.

Multilingual Rules

  • Default language owns x-default unless the site has a separate language selector page.
  • Every localized page must declare its own canonical URL.
  • Hreflang groups must contain only true equivalents, not loosely related pages.
  • If translation quality is unknown, mark the localized page as draft or deferred, not published.

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.
