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.

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 | $0.00099 | $0.02573 |
| Opus 5 | $0.00049 | $0.01287 |
| Sonnet 5 | $0.00020 | $0.00515 |
| Haiku 4.5 | $0.00010 | $0.00257 |
Grade A, and why
schema-markup-generator 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 7d 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 — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Schema Markup Generator
This skill creates Schema.org structured data markup in JSON-LD format to help search engines understand your content and enable rich results in SERPs.
When This Must Trigger
Use this when the conversation involves any of these situations — even if the user does not use SEO terminology:
Use this whenever the task needs a shippable asset or transformation that should feed directly into quality review, deployment, or monitoring.
- Adding FAQ schema for expanded SERP presence
- Creating How-To schema for step-by-step content
- Adding Product schema for e-commerce pages
- Implementing Article schema for blog posts
- Adding Local Business schema for location pages
- Creating Review/Rating schema
- Implementing Organization schema for brand presence
- Any page where rich results would improve visibility
What This Skill Does
- Schema Type Selection: Recommends appropriate schema types
- JSON-LD Generation: Creates valid structured data markup
- Property Mapping: Maps your content to schema properties
- Validation Guidance: Ensures schema meets requirements
- Nested Schema: Handles complex, multi-type schemas
- Rich Result Eligibility: Identifies which rich results you can target
Quick Start
Start with one of these prompts.
Generate Schema for Content
Generate schema markup for this [content type]: [content/URL]
Create FAQ schema for these questions and answers: [Q&A list]
Specific Schema Types
Create Product schema for [product name] with [details]
Generate LocalBusiness schema for [business name and details]
Audit Existing Schema
Review and improve this schema markup: [existing schema]
Data Sources
With ~~web crawler connected: Automatically crawl and extract page content (visible text, headings, lists, tables), existing schema markup, page metadata, and structured content elements that map to schema properties.
With manual data only: Ask the user to provide:
- Page URL or full HTML content
- Page type (article, product, FAQ, how-to, local business, etc.)
- Specific data needed for schema (prices, dates, author info, Q&A pairs, etc.)
- Current schema markup (if optimizing existing)
What ships with it
4 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.
