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 5.1 | $0.00149 | $0.01407 |
| Opus 5 | $0.00075 | $0.00704 |
| Sonnet 5 | $0.00030 | $0.00281 |
| Haiku 4.5 | $0.00015 | $0.00141 |
Grade A, and why
privacy-pagamenti 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 12d 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.

Privacy Pagamenti e Abbonamenti · Payments Privacy
🇮🇹 Versione italiana qui sotto · 🇬🇧 English version below
Quando un sito/app gestisce pagamenti o abbonamenti, applicare queste regole.
Regola d'oro: mai toccare i dati della carta
- Il numero di carta NON deve mai transitare dal proprio server né essere salvato nel proprio DB (requisito PCI-DSS). Usare sempre checkout/elementi ospitati dal provider: Stripe Checkout / Payment Element, PayPal Smart Buttons.
- Nel DB salvare SOLO: ID cliente del provider (es.
cus_...), ID abbonamento, stato, ultime 4 cifre e brand se forniti dal provider. - Le chiavi segrete (
sk_..., client secret) vivono solo in variabili d'ambiente lato server. Nel frontend solo chiavi pubblicabili.
Webhook: sempre verificati
Lo stato di pagamenti/abbonamenti si aggiorna SOLO da webhook verificati, mai dal redirect del browser (falsificabile).
// Stripe (Express) — il body deve essere RAW
app.post('/webhook', express.raw({type: 'application/json'}), (req, res) => {
let event;
try {
event = stripe.webhooks.constructEvent(
req.body, req.headers['stripe-signature'], process.env.STRIPE_WEBHOOK_SECRET
);
} catch (err) { return res.status(400).send('Firma non valida'); }
// gestire event.type: checkout.session.completed, invoice.paid,
// invoice.payment_failed, customer.subscription.deleted ...
res.json({received: true});
});
Per PayPal usare l'API di verifica firma webhook. Rendere i gestori idempotenti (stesso evento ricevuto due volte = nessun doppio effetto): salvare gli event.id processati.
Abbonamenti
- Gestire sempre: pagamento fallito (grace period + email), cancellazione (accesso fino a fine periodo), upgrade/downgrade con proratazione del provider.
- La cancellazione deve essere facile quanto l'iscrizione (obbligo in UE/USA). Prevedere pagina "gestisci abbonamento" (Stripe Customer Portal è la via più semplice).
- Prezzi e importi: mai fidarsi di valori inviati dal client; il server usa solo i Price ID configurati.
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.
- 12d ago First seen · 82 lines · 149 tokens per session scan A de7229695240
privacy-pagamenti is a skill published in the GitHub repository ayalaphiscan/web-security-guard (4 stars, last pushed 3mo ago), licensed MIT. It adds 149 tokens to every session and 1,407 once invoked, about $0.0007 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 2026-08-31.
