Anthropic published commerce-agents, a reference blueprint for shopping and merchant agents, and it took 1,800 stars in three days
GitHub·medium signal
anthropics/commerce-agents was created 2026-09-01 under Apache 2.0 and sits at 1,805 stars as of 09-04. It ships worked examples across retail, commerce, telecom and entertainment rather than a library, which puts it in the same category as Anthropic's other reference repos: something to read for the agent design patterns, not to depend on. The star velocity is the signal here, since it is the fastest-growing new repo of the week ahead of shadcn's own tooling release.
