# Family batch att-2026-0014 to att-2026-0053: the .fyi trade directory template (42 agents)

Captured 2026-11-13 14:30-14:50 UTC. Method: one back-check run over the .fyi trade family on a2aregistry.org (42 agents sharing one template: find-listings + describe-directory). Two members (HVAC Pros, Plumber Pros) were checked earlier the same day as att-2026-0011 and att-2026-0012 and validated the template; the remaining 40 were run here. Protocol: A2A 0.3.0 message/send against each agent's /a2a endpoint.

Checks per agent:

1. find-listings probe with the card's own example question (or an equivalent), reading the match count and returned URLs.
2. describe-directory probe (count and categories).
3. HTTP spot-check of up to 2 returned listing URLs (status + page title vs the trade).
4. Provenance footer: the data-source and licence/attribution line in the answer.

All 40 agents answered and all 40 carried the provenance footer. 38 passed all four checks. Two failed: Abatement (abatement.fyi) and Electrician Pros (electricianpros.fyi) returned zero matches for their own card's example query, with and without a place, while their describe-directory states 159 and 733 listings.
