gtm_list_contentList GTM queue items for the authenticated PromptUI user.
gtm_get_analyticsRead current PromptUI GTM channel analytics and workspace-scoped verified commerce outcomes. Attribution is reported separately from causality; unavailable spend/cost coverage stays explicit.
gtm_publish_contentPublish one GTM content item to a connected social platform.
gtm_generate_contentGenerate and persist a new GTM content draft for the authenticated user. Repeating the same call within 10 minutes returns the same draft.
build_appBuild a working web app from a prompt with PromptUI. Starts an asynchronous build (costs credits from the authenticated account) and returns a buildId — poll get_build_status for progress and the preview link.
get_build_statusCheck the status of a PromptUI build started with build_app. Returns building / needs_clarification / completed (with a shareable previewUrl) / failed.
deploy_appDeploy a completed PromptUI build to a live URL. The first deploy of each app is charged; redeploying that same app is free. If publishing needs a paid plan (a Free account, when the publish gate is on), the tool returns how to start the Build free trial instead of deploying.
list_buildsList the authenticated user's recent PromptUI builds with their statuses.
