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 | $0.00184 | $0.02529 |
| Opus 5 | $0.00092 | $0.01264 |
| Sonnet 5 | $0.00037 | $0.00506 |
| Haiku 4.5 | $0.00018 | $0.00253 |
Grade A, and why
gemini 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 4d 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 — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini — Cross-Model Second Opinion
You are orchestrating a cross-model review by launching Google's Gemini CLI as an independent reviewer. Gemini brings native Google ecosystem knowledge — especially valuable for Google Ads, Search Console, and SEO decisions where Google's own AI has deeper context about how their platforms work.
Unlike the code-only review pattern, this skill handles three types of changes:
- Code changes — diffs, new files, refactors
- Google Ads changes — campaign structure, bid strategies, keyword lists, negative keywords, ad copy, budget allocation
- SEO metadata changes — title tags, meta descriptions, schema markup, robots directives, sitemap updates, content rewrites
Step 0 — Detect Gemini CLI
command -v gemini >/dev/null 2>&1 && echo "GEMINI_FOUND" || echo "GEMINI_NOT_FOUND"
If GEMINI_NOT_FOUND: Stop and tell the user:
Gemini CLI is not installed. Install it with:
npm install -g @google/gemini-cliThen run
geminionce to authenticate with your Google account, and retry.
If GEMINI_FOUND: continue silently.
Step 1 — Detect Mode
Parse the user's request to determine the mode. Match against these patterns:
| Mode | Trigger phrases |
|---|---|
| review | "review", "check", "look at", "pass/fail", "gate", "approve" |
| challenge | "challenge", "stress test", "break", "adversarial", "find holes", "poke holes" |
| consult | "consult", "ask", "what does gemini think", "opinion", "advice", "strategy" |
If ambiguous: default to review for changes that exist in the diff, or consult if the user is asking a question with no pending changes.
Step 2 — Detect Change Type
Determine what kind of changes are being reviewed. Check in this order:
2a — Check for Google Ads changes
Look for signs of Ads-related work in the current conversation context:
- Recent MCP tool calls to universal
mcp__NotFair__google_ads_*tools or a supported dedicated Google Ads namespace - Discussion of campaigns, keywords, bids, budgets, ad copy, negative keywords
- Files like
.notfair/change-log.jsonor Ads-related config changes
What ships with it
1 file 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.

gemini is a skill published in the GitHub repository nowork-studio/notfair-plugin (3,447 stars, last pushed 6d ago), licensed MIT. It adds 184 tokens to every session and 2,529 once invoked, about $0.0009 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 2026-08-30.
