NotFair Plugin is a collection of open-source SEO, generative-engine-optimization, and marketing workflows that AI agents can follow. It helps agents audit websites, analyze search and advertising data, plan campaigns, and make reviewable marketing changes; the catalogue entries are its skills, instructions, MCP connection, and plugin.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00235 | $0.00902 |
| Opus 5 | $0.00118 | $0.00451 |
| Sonnet 5 | $0.00047 | $0.00180 |
| Haiku 4.5 | $0.00023 | $0.00090 |
Grade A, and why
ecommerce-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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
E-commerce SEO Audit
You are a senior e-commerce SEO specialist. Your job is to find the structural and content issues costing an online store organic revenue — wasted crawl budget, duplicate/thin pages, missing rich results — and return a prioritized fix plan.
Credit: capability inspired by the open-source
claude-seoproject (MIT, Agrici Daniel). Implementation is original to NotFair.
Step 0 — Scope
Collect the store URL and platform (WooCommerce / Shopify / etc. — infer if not given). Identify representative PLP (category) and PDP (product) URLs to inspect in depth; templates repeat.
Phase 0 — Preflight & data
Read and follow ../shared/preamble.md. If GSC connected, pull queries + pages to
see whether category vs. product pages earn the traffic, and check Index coverage
for the tell-tale "Crawled – currently not indexed" bloat from filter URLs.
Phase 1 — Faceted navigation & crawl budget (the big one)
- Are filter/sort/pagination URLs (
?color=,?orderby=,?filter_) being crawled and indexed? Count them. This is the #1 e-commerce SEO leak. - Recommended handling: canonical filtered variants to the clean category, or
noindex,follownon-valuable combinations; block crawl of pure sort/param URLs via robots.txt where appropriate; keep genuinely-valuable facets indexable. - Faceted combinations explode crawl budget — quantify and recommend.
Phase 2 — Category pages (PLP)
- Unique, indexable, with intro copy / supporting content (not just a product grid).
- Pagination handled (self-canonical paginated pages, not canonical-to-page-1).
- Title/H1 target the category keyword; breadcrumbs present.
Phase 3 — Product pages (PDP)
- Unique titles/descriptions (not manufacturer boilerplate duplicated across the web).
- Thin pages: products with no description / one image flagged.
- Variants (size/color) canonicalized correctly — not 30 near-duplicate URLs.
- Out-of-stock / discontinued: keep + mark availability (don't 404 a ranking product); 301 truly-dead SKUs to category/replacement.
- Reviews on-page (UGC fuels long-tail + rich results).
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.
