Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.00900 |
| Opus 5 | $0.00047 | $0.00450 |
| Sonnet 5 | $0.00019 | $0.00180 |
| Haiku 4.5 | $0.00009 | $0.00090 |
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.

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
- Read the semantic core, entity-topic map, site constraints, languages, and content model.
- Identify the canonical page role for each cluster/entity/topic.
- Define route patterns before individual URLs.
- Set canonical policy per page role.
- Define hreflang groups for localized equivalents.
- Mark page status:
planned,draft,published,noindex, ordeferred. - Record duplicate-content risks and ownership boundaries.
- Produce
url-map.yamlusing assets/url-map.template.yaml. - Hand off to
internal-link-graph-architectandtechnical-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-defaultunless 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
draftordeferred, not published.
What ships with it
5 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.
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.

information-architecture-seo is a skill published in the GitHub repository sergekostenchuk/seo-llm-skill-cluster (39 stars, last pushed 3mo ago), licensed MIT. It adds 94 tokens to every session and 900 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
