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.

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 | $0.02499 | $0.02499 |
| Opus 5.5 | $0.01000 | $0.01000 |
| Sonnet 5.5 | $0.00500 | $0.00500 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
notfair-plugin AGENTS.md 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 9d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NotFair — Skill Resolver for AI Agents
This file is the universal entry point. Any AI coding agent (Claude Code, Codex, Hermes, Cursor, etc.) reads this to know which NotFair skill to run for which user intent.
If you are an agent and a user mentions Google Ads, Meta Ads, SEO, GEO, or anything in the tables below, route to the named skill.
For repository maintenance, read docs/plugin-development.md. Installed workflow instructions live in the skills below.
How to use this file
- Match the user's intent against the rows below.
- Read the named skill's
SKILL.mdfrom the path shown. - Follow the procedure in that SKILL.md exactly.
Skills under skills/ are host-agnostic; each entry loads its full workflow from the corresponding category folder — they work the same on every supported agent host.

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.
