Alternatives to a2a_list_public_agents
10 tools grouped by commerce-retail — a rough corpus-diversity category (see methodology), not a rigorous similarity match. Ranked within measurement tier, same as search — a shallow-tier tool is never pushed down for having less data; it’s shown in its own band with its state stated plainly.
