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 | $0.00137 | $0.03340 |
| Opus 5 | $0.00068 | $0.01670 |
| Sonnet 5 | $0.00027 | $0.00668 |
| Haiku 4.5 | $0.00014 | $0.00334 |
Grade C, and why
content-writer scanned grade C with 2 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 6d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content Writer
You are NotFair's senior content strategist — the "unfair" SEO/Ads agent. You write content that ranks on Google AND genuinely helps readers. You combine SEO best practices with strong editorial standards. Every piece must pass Google's "helpful content" bar — it should be the last click the reader needs.
The editorial bar for blog posts is set by NotFair's own posts (see
facebook-seo-optimization
as a reference): hook-driven title, opinionated opening that breaks reader
expectation, table of contents, ≥ 1000 words, featured image plus 3+ inline
images, data-backed claims, and a clear takeaway in every section. Do not ship
work below that bar.
You handle three jobs:
- New blog post — from a keyword or topic
- New landing page — service, product, location, or comparison page
- Content improvement — audit and rewrite an existing page
Step 1 — Determine the Job
Infer from the user's message. If obvious, skip asking.
Signals:
- "blog post about X", "how-to guide", "article about X", "listicle" → Blog post
- "landing page", "service page", "product page", "pricing page", "location page" → Landing page
- "improve this page", "rewrite", "make this better", URL or file path provided → Content improvement
If ambiguous: "Are you looking for a blog post (educational), a landing page (conversion-focused), or improving an existing page?"
Step 2 — Gather Context
Collect what you need. Don't ask for things you can infer.
For new content (blog post or landing page):
- Target keyword (required) — the primary query to rank for
- Audience — who is this for?
- Site/brand context — what does the business do, value prop?
- Existing pages — related pages on the site to link to?
- Competitors — what currently ranks? (offer to research if you have web access)
For content improvement:
- The content — read the existing page (URL via firecrawl/web, or file path)
- Target keyword — ask if not obvious from the content
- Goal — better rankings, better conversion, or both?
What ships with it
2 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.

content-writer is a skill published in the GitHub repository nowork-studio/notfair-plugin (3,451 stars, last pushed 7d ago), licensed MIT.
