Commerce agent blueprint ships with every write staged

Anthropic’s commerce-agents repo ships under Apache 2.0 as a reference implementation that isn’t maintained and doesn’t accept contributions. Nothing in it touches live commerce. Checkout renders the cart for the host app to complete, and every merchant write stays staged until a person approves it.

Four verticals run over the same libraries, retail, travel, telecom and entertainment, each with a storefront and a merchant portal. One agent definition, prompt, skills, tool contracts and gates, runs three ways: on the Messages API, the Claude Agent SDK, and Managed Agents.

Fencing, provenance gates, caps, memory validation and the merchant approval gate all run inside the tool call and hold on every path. The examples ship with no authentication, and the MCP servers bind to loopback.
