### Tool changes

- 2026-10-31 `catalog.search` changed (description, inputSchema) **meaning changed**
  - before: Search shops that publish a signed Agent Card, plus shops listed from public data (provenance "unclaimed": search-only, no door). Each result gives the shop's DID, origin, Agent Card URL and the matching products, so an agent can go straight to that shop's Agent Entry with a signed request.
  - after: Search shops that publish a signed Agent Card, plus shops listed from public data (provenance "unclaimed": search-only, no door). Shops are listed by how well their PRODUCTS match, best first; demo stores, wholesalers, off-topic sellers and non-shop sites (reviews, how-to, repair, coupons, with no known price) are left out and counted in `filtered`. Each result gives the shop's origin, DID, Agent Card URL and its best matching products (name, price, link, image when the shop is signed or claimed), so an agent can go straight to that shop's Agent Entry with a signed request. Without `limit` the answer is the top 5 shops with 3 products each (`more` says how many further shops matched); pass `limit` for more shops, or use GET /catalog/search for the full rows.
