ap2-checkout-mandate skillA

ap2-checkout-mandate is agent-read markdown (skill) from orcaqubits/agentic-commerce-skills-plugins: Implement the AP2 Checkout Mandate — the credential authorizing completion of a checkout, in its open (constrained) and closed (merchant-verified) forms, with merchant-signed checkout payloads, checkout hashes, and user confirmation on a trusted surface. Formerly called the Cart Mandate. Use when building cart/checkout authorization, signing, and verification..

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.
