  Packaged Agent Skills authored by API Evangelist from the provider's own
  contracts and documentation. Every operationId referenced was verified against
  openapi/mailchimp-marketing-api-openapi-original.json (Mailchimp Marketing API
  3.0.91) and openapi/mailchimp-transactional-api-openapi-original.json (Mailchimp
  Transactional API 1.4.1), both harvested 2026-08-13. Runtime rules come from
  conventions/mailchimp-conventions.yml, rate-limits/mailchimp-rate-limits.yml,
  errors/mailchimp-problem-types.yml and sandbox/mailchimp-sandbox.yml. Mailchimp
  does not publish its own agent skills or AGENTS.md.
description: >-
  Five operating instructions for driving the Mailchimp Marketing and
  Transactional APIs safely from an agent. Each mirrors a marquee flow already
  modelled in arazzo/ and carries the two rules that matter most on this provider:
  there is no idempotency key anywhere in either API, and the Marketing API allows
  only 10 simultaneous connections with no rate-limit response headers.
