auditing-payment-callback-and-amount-integrity skillA

auditing-payment-callback-and-amount-integrity is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit payment provider callbacks and settlement notifications for the trust that lets an attacker forge or alter a payment result: a callback whose signature is not verified so a spoofed success is accepted, an amount or currency taken from the callback or client rather than reconciled against the order the server created, a success notification not bound to a specific order so it can be replayed onto another order, and a settled status trusted without confirming it out of band with the provider.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add unboundcompute/security-agent-skills/auditing-payment-callback-and-amount-integrity@git:20260829.b60f9b2
Exact content
mdr add unboundcompute/security-agent-skills/auditing-payment-callback-and-amount-integrity@sha256:a7f582539455366a

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
