  documented at https://developers.citrusad.com/integration/reference/. Searched
  first for provider-published Agent Skills or an AGENTS.md — Epsilon publishes
  neither.
description: >-
  Agent Skills for the Epsilon Retail Media APIs, one per marquee flow. Every
  operationId referenced is verified present in a published OpenAPI in openapi/;
  none is invented. Each skill carries the cross-cutting rules that are not in the
  spec — the three auth models, the three error envelopes, the absent idempotency
  and the blind 429 backoff.

    api: Epsilon Retail Media Integration API
    summary: Empty sandbox to a catalog that returns ads — create catalog, sync products, verify, confirm generation.

    api: Epsilon Retail Media Integration API, Filter Mapping API, Cross-Sell Category API
    summary: Sync shoppers and segments, map filters, define cross-sell categories — across three APIs with three credential shapes.
    operations: [create-or-update-a-customer, retrieve-a-list-of-customers, retrieve-a-customer, manage-customers-and-segments, createFilterMapping, listFilterMappings, getFilterMapping, updateFilterMapping, deleteFilterMapping, listCrossSellCategories, createCrossSellCategory, getCrossSellCategory, deleteCrossSellCategory]

shared_cautions:
  - No idempotency mechanism exists anywhere on this platform. POST /orders drives attribution and billing and has no replay protection.
  - 429 is declared but carries no Retry-After and no RateLimit-* headers, so backoff must be client-side and blind.
  - Error envelopes differ by API generation; do not write one parser.
  - No sandbox is self-service; a Technical Account Manager provisions credentials and hosts.
