Fonte de verdade

O arquivo reference/endpoints.json é o catálogo canônico dos endpoints — gerado por crawl da documentação oficial em developers.facebook.com/documentation/business-messaging/... e developers.facebook.com/docs/messenger-platform/....

Cada tool wrapea um endpoint desse catálogo. Para adicionar suporte a um endpoint novo:

  1. Adicionar entrada em reference/endpoints.json
  2. Criar o tool em src/tools/<produto>.ts usando graphRequest() de src/client.ts
  3. Registrar em src/index.ts (já automático via registerXxxTools)
