ensure-pipelines-host

Scope: When no host is bound to the source env, this skill detects any existing host (Custom or PE) for reuse, or — in NoHost state — offers three provisioning paths: a new Platform Host (recommended; idempotent, ~3–5 min); a new Custom Host (admin-only, ~5–10 min); or PPAC manual provisioning (fallback). Implementation details — endpoint names, template names, BAP audience — live in Phase 4.0 / 4.A / 4.C below; user-facing prose stays focused on outcomes.

Power Platform Pipelines need a host environment — a Dataverse environment with the Power Platform Pipelines managed solution installed, where pipelines, stages, run history, and artifacts live. The existing setup-pipeline and deploy-pipeline skills assume a host is already configured. This skill closes that gap.

What we know (sources of truth)

This plan is grounded in three primary sources, in priority order:

useGetOrCreatePlatformEnvironment.v4.ts (Microsoft-internal client source — power-platform-ux/packages/powerapps-appdeployment-ux/src/hooks/v4/). Defines the exact HTTP contract for Platform Environment provisioning: endpoint, body, headers, polling.
ProjectHostProvider.tsx (same repo, src/components/ProjectHostProvider/). Defines the exact resolution order the Power Apps UI uses to determine which environment is the project host for a source environment. We mirror that order so this skill agrees with the UI.
eng.ms createcustompipelineshost (Microsoft-internal). Documents the Custom Host fast-path: a D365_ProjectHost org template that ships the Pipelines app pre-installed, callable through the standard environment-creation API.

Public Microsoft Learn (learn.microsoft.com/power-platform/alm/{platform-host-pipelines, custom-host-pipelines, set-a-default-pipelines-host}) is the user-facing description of the same flows; we cite it for behaviors users will recognize. HARs in PipelinesDeployScenario.har and Pipelines.har confirm the read-side calls.
