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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00068 | $0.01609 |
| Opus 5 | $0.00034 | $0.00805 |
| Sonnet 5 | $0.00014 | $0.00322 |
| Haiku 4.5 | $0.00007 | $0.00161 |
Grade C, and why
upgrade scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf "$NEW_CACHE_DIR" How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/notfair:upgrade
Upgrade the NotFair plugin to the latest version and show what's new.
Key paths
| What | Path |
|---|---|
| Marketplace repo | ~/.claude/plugins/marketplaces/nowork-studio/ |
| Plugin cache | ~/.claude/plugins/cache/nowork-studio/notfair/<version>/ |
| Installed plugins | ~/.claude/plugins/installed_plugins.json |
| Update state | ~/.toprank/ (intentionally preserved — see CHANGELOG 0.24.0) |
Inline upgrade flow
This section is used when a skill preamble outputs UPGRADE_AVAILABLE.
Step 1: Auto-upgrade
Log "Upgrading NotFair v{old} → v{new}..." and proceed to Step 2.
Step 2: Detect current install
First check for dev symlink (see "Dev symlink detection" section). If detected, stop — do not upgrade.
# Find the currently installed plugin path
INSTALLED_DIR=$(ls -d ~/.claude/plugins/cache/nowork-studio/notfair/*/ 2>/dev/null | grep -v '.bak' | head -1)
if [ -z "$INSTALLED_DIR" ]; then
echo "ERROR: NotFair plugin not found in cache"; exit 1
fi
MARKETPLACE_DIR="$HOME/.claude/plugins/marketplaces/nowork-studio"
if [ ! -d "$MARKETPLACE_DIR/.git" ]; then
echo "ERROR: marketplace repo not found at $MARKETPLACE_DIR"; exit 1
fi
echo "Current install: $INSTALLED_DIR"
echo "Marketplace repo: $MARKETPLACE_DIR"
Step 3: Save old version
OLD_VERSION=$(cat "$INSTALLED_DIR/VERSION" 2>/dev/null | tr -d '[:space:]' || echo "unknown")
Step 4: Update marketplace repo and install
cd "$MARKETPLACE_DIR"
git fetch origin
git reset --hard origin/main
NEW_VERSION=$(cat VERSION | tr -d '[:space:]')
GIT_SHA=$(git rev-parse HEAD)
# Create new versioned cache directory
NEW_CACHE_DIR="$HOME/.claude/plugins/cache/nowork-studio/notfair/$NEW_VERSION"
if [ -d "$NEW_CACHE_DIR" ]; then
rm -rf "$NEW_CACHE_DIR"
fi
mkdir -p "$NEW_CACHE_DIR"
# Copy plugin files (exclude .git to save space)
rsync -a --exclude='.git' "$MARKETPLACE_DIR/" "$NEW_CACHE_DIR/"
If the copy fails, warn: "Upgrade failed — the old version is still active. Run /notfair:upgrade manually." and stop.
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.

upgrade is a skill published in the GitHub repository nowork-studio/notfair-plugin (3,690 stars, last pushed 3d ago), licensed MIT. It adds 68 tokens to every session and 1,609 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
