# CMS Overview — BrandApp Playground

> Read-only content APIs — posts, post groups, and tags — with authoring handled in Reopt Studio.

- SDK module: `@reopt-ai/brandapp-sdk/cms`

## Shape of the module

From SDK 1.8 the CMS client is read-only: Reopt Studio owns authoring, and the SDK covers
the query scenarios an external site actually needs — list with filters, fetch one by id
or slug, resolve group metadata, and enumerate tags.

The dev server's CMS handler implements the same endpoints as a hosted BrandApp, so
`REOPT_DEV_MODE=true` works offline against seeded sample content.
