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.

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 | $0.00109 | $0.00719 |
| Opus 5 | $0.00055 | $0.00360 |
| Sonnet 5 | $0.00022 | $0.00144 |
| Haiku 4.5 | $0.00011 | $0.00072 |
Grade A, and why
seo-image-audit 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.

seo-image-audit
Family: seo Status: Stable
Purpose
The audit half of image SEO (split from generation because the two have different legal, asset, and API risk). Inventories a page's images and scores each on the dimensions that affect search and performance. The free path (fetch + parse) is the whole product; DataForSEO only adds live image-SERP context.
Triggers
- "image seo" / "image audit" / "image optimization"
- "alt text" / "image metadata"
- "convert to webp" / "convert to avif"
- "image rankings" / "google images"
Inputs
- Page URL or local HTML/build path (or an image directory)
- Optional: target keyword(s) for alt-text relevance
Steps
- Inventory images — fetch the page (or scan the directory) and list every
image with its
src, dimensions, format, and file size. - Score each image:
- Alt text — present? descriptive? keyword-relevant without stuffing?
(decorative images should have empty
alt=""). - Format — modern (WebP/AVIF) vs legacy (JPEG/PNG); flag conversion wins.
- File size / dimensions — oversized for display size? recommend target.
- Responsive —
srcset/sizes/<picture>present where useful? - Lazy loading —
loading="lazy"below the fold; eager for the LCP image. - CLS — width/height or aspect-ratio declared to reserve space?
- Alt text — present? descriptive? keyword-relevant without stuffing?
(decorative images should have empty
- Optional enrichment — if the DataForSEO extension is configured, add image SERP rankings; otherwise state, in one line, what it would add.
- Render findings grouped Critical / High / Medium / Low, each with a concrete
fix and (for format/size) the recommended target. For "convert to webp/avif"
requests, output ready-to-run conversion commands per image (
cwebp, ImageMagickmagick, or a Sharp snippet) as the actionable deliverable — running them needs that tool installed (see Notes).
Outputs
- Per-image findings table with prioritized fixes
- A summary of the biggest performance wins (format + size)
- A short "what paid data would add" note on the free path
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.

seo-image-audit is a skill published in the GitHub repository ZachArticulateV/designer-pro-and-seo (8 stars, last pushed 2mo ago), licensed MIT. It adds 109 tokens to every session and 719 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 2026-08-31.
