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: 2 findings, up to medium
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 | $0.00147 | $0.08952 |
| Opus 5.5 | $0.00059 | $0.03581 |
| Sonnet 5.5 | $0.00029 | $0.01790 |
| Haiku 4.5 | $0.00015 | $0.00895 |
Grade A, and why
cardcom-payment-gateway scanned grade A 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 15d 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.

Cardcom Payment Gateway
Legal notice
This is a free technical integration guide operated by an AI model. It explains how to call the Cardcom API and how the Israeli invoicing rules bear on it. All of its outputs are produced automatically by an AI model, with no involvement, review, or approval by a tax adviser, accountant, or lawyer. Nothing here is a tax opinion or professional advice, and an AI model may err, omit data, or present a wrong conclusion.
The documents this integration produces are tax documents. Responsibility for issuing them correctly, for reporting, and for paying the tax is yours, the binding computation is the Tax Authority's, and representation before the Tax Authority is reserved to those permitted by law. Whether a given invoice requires an allocation number, and whether input VAT may be deducted, are determinations for your accountant on your actual facts. Have a tax adviser or accountant review the invoicing configuration before you go live, and handle cardholder data in accordance with PCI DSS. All use of this skill's output is the user's sole responsibility.
Overview
Cardcom is an Israeli payment processor with a unique strength: integrated invoice and receipt generation compliant with Israeli tax law. While other Israeli gateways handle only the payment, Cardcom can automatically generate tax invoices (hashbonit mas) and receipts (kabala) as part of the payment flow, something Israeli businesses are legally required to issue.
This skill covers Cardcom's REST API V11 for payments, tokenization, recurring billing and documents. Endpoint and field names come from the official V11 OpenAPI specification.
Official docs: https://secure.cardcom.solutions/Api/v11/Docs (interactive API reference with the full OpenAPI schema). V11 is the current API as of 2026; there is no public V12.
Support center: https://support.cardcom.solutions
Cardcom in the Israeli landscape: competes with Tranzila and other Israeli gateways. Cardcom publishes a starting rate of about 1.2% that falls with volume; that is a floor, not a quote, so send the user to Cardcom for an actual figure. The distinguishing feature remains the built-in tax document generation. For Tranzila integration use the tranzila-payment-gateway skill instead.

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.
