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.

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 | $0.00009 | $0.01752 |
| Opus 5.5 | $0.00004 | $0.00701 |
| Sonnet 5.5 | $0.00002 | $0.00350 |
| Haiku 4.5 | $0.00001 | $0.00175 |
Grade A, and why
adyen-knowledge-patch 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 1mo 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 — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Adyen Knowledge Patch
Use this skill when implementing or upgrading Adyen Web, Drop-in, Components, sessions flows, or Checkout API v72 integrations. Consult the topic reference that matches the integration surface, then apply the quick-reference rules below where relevant.
Reference index
| Reference | Topics |
|---|---|
| Web components and sessions | Select rendering, sessions behavior, payment-method components, localization, payloads, and amount updates |
| Cards and authentication | 3DS2, BIN lookup, Secured Fields, ACH, card callbacks, TypeScript surfaces, and card-brand behavior |
| Wallets and mobile payments | Apple Pay, Google Pay, UPI, browser support, issuer filtering, and environment handling |
| Checkout API v72 | Request validation, precedence, expiry, status codes, redirects, line-item tax fields, and partial payments |
Breaking changes and upgrade checks
Checkout API v72 request validation
Checkout API v72 rejects values that fail the new validation requirements in
requests such as /payments and /sessions. Audit these fields before an
upgrade:
billingAddress.postalCodebillingAddress.stateOrProvinceCodecaptureDelayHoursdateOfBirthdeliveryAddress.postalCodedeliveryAddress.stateOrProvinceCodeentityTypemetadatareferencereturnUrlshopperEmailshopperIPshopperName.firstNameshopperName.lastNamesocialSecurityNumbertelephoneNumber
For card payments, a card number in holderName is rejected with Invalid
card holder name. Check mappings that could put PAN input in that parameter.
Checkout API v72 response handling
Some validation and rate-limit failures return HTTP 422 or 429 instead of
500. Treat them as validation and throttling responses rather than server
failures.
In Drop-in /sessions redirects, use redirectResult to complete payment.
The redirect no longer supplies the erroneous payload parameter in its
place.
What ships with it
5 files 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.

adyen-knowledge-patch is a skill published in the GitHub repository Nevaberry/nevaberry-plugins (24 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 1,752 once invoked, about $0.0000 per session on Opus 5.5. 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.
