  Packaged Agent Skills for the mailboxlayer Verification API. Every step is grounded in an
  operationId that exists verbatim in the OpenAPI 3.1.0 APILayer publishes on SwaggerHub —
  checkEmail and bulkCheckEmails are the only two operations mailboxlayer has. Searched
  first for provider-published skills or an AGENTS.md; APILayer publishes none.

  - file: mailboxlayer-verify-single-address.md
    name: Verify a single email address with mailboxlayer
    api: openapi/_original/mailboxlayer-swaggerhub-openapi.json
    operations: [checkEmail]
    summary: >-
      Single-address verification, correct response handling across the vendor envelope,
      the 422 FastAPI shape and the HTTP error responses, plus the three field traps
      (tri-state catch_all, advisory did_you_mean, unbanded score).
  - file: mailboxlayer-bulk-list-hygiene.md
    name: Clean an email list in bulk with mailboxlayer
    api: openapi/_original/mailboxlayer-swaggerhub-openapi.json
    operations: [bulkCheckEmails, checkEmail]
    summary: >-
      Plan-gated bulk verification: batch sizing to the 25/100 ceilings, the array-vs-object
      response ambiguity, quota arithmetic, pacing without rate-limit headers, and the
      per-address fallback when the plan has no bulk access.
