payment-payment-pci-security

payment-payment-pci-security is a cursor rule for coding agents from vtex/skills. It costs 6,078 tokens per session, scanned A, original, no licence file.

A set of rules for protecting credit-card data in VTEX payment connectors. It covers PCI DSS, a security standard for card payments, secure proxy flows, token creation, sensitive data handling, and provider forwarding headers.

In plain words
What is it for?
Use it when handling card data, tokenizing cards through Secure Proxy, creating custom tokens, implementing secureProxyUrl flows, or setting the X-PROVIDER-Forward-To header.
Why use it?
It helps reduce the risk of exposing card information or using secure proxy requests incorrectly. It also defines where secure proxy access applies and how provider requests should be forwarded.

Token cost

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.

Security

Grade A, and why

payment-payment-pci-security scanned grade A 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 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.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

const acquirerResponse = await fetch("https://api.acquirer.com/v2/payments", { method: "POST",

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
