seo-images

seo-images is a skill for Claude Code, Codex from oegeyilmaz9/seo-aeo-geo-ultimate. It costs 44 tokens per session (782 once invoked), scanned A, original, Apache-2.0.

A method for reviewing images on web pages for accessibility, search discoverability, ownership, and delivery performance.

In plain words
What is it for?
Use it to inventory meaningful and decorative images, check surrounding context and captions, review alternative text and controls, inspect delivery details, and assess image sitemaps.
Why use it?
It prevents teams from guessing what an image does, whether it needs alternative text, or how it affects users and crawlers. It keeps licensing, loading, and accessibility concerns separate.

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-images 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Images

Purpose

Improve the way meaningful visual assets are understood and delivered to people and crawlers. This skill separates accessibility, rendering/performance, asset rights, and image-search discoverability instead of treating them as one score.

Read references/image-review-protocol.md before preparing a formal media recommendation.

Input gate

Require the rendered page or asset inventory, image purpose/context, source URL, intrinsic dimensions/format/size, delivery behavior, locale, accessibility context, and any available field/lab evidence. Ask who owns the image/license and whether an image is content, UI decoration, hero/LCP candidate, product/media asset, or purely decorative.

Do not infer file format, dimensions, loading behavior, or user impact from a filename. Do not recommend an image or alt text without seeing its page context.

Workflow

  1. Inventory by purpose. Map each material image to the visible topic, page region, adjacent text/caption, owner/license, and delivery URL. Mark decorative images as decorative rather than inventing alt text.
  2. Review accessibility. Check meaningful alternative text, captions/nearby explanation, controls, contrast/legibility where text is embedded, and responsive mobile rendering. Alt text explains the image’s purpose in context; it is not a keyword field.
  3. Review delivery. Inspect dimensions, responsive candidates, intrinsic width/height or aspect-ratio reservation, loading priority, lazy loading behavior, cache/CDN policy, and actual LCP/CLS/interaction evidence when available. A newer format is not automatically an improvement; evaluate support, source quality, byte savings, and visual fidelity.
  4. Review discovery/metadata. Check whether significant images are reachable in rendered content and whether page context, canonical URLs, structured data, and image sitemap use are truthful and relevant. Route structured data to seo-schema and sitemap changes to seo-sitemap.
  5. Plan safe changes. For each action name the asset/template scope, owner, accessibility/content review, visual QA, performance test, approval, and rollback. Send systemic delivery changes through seo-action-plan.

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.
