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.
Three host shapes the tenant can be in
| Shape | How it got there | Where it lives | Org template |
|---|
| Platform Host (PE) | Auto-provisioned by getOrCreate BAP call (or as a side-effect of first navigation to the Pipelines page in make.powerapps.com). Hidden from the env picker. One per tenant. | Microsoft-managed Dataverse env in tenant's home geo | D365_1stPartyAdminApps |
| Custom Host | Created by an admin via PPAC Deployments → New custom host, or via the standard env-create API with the D365_ProjectHost template, or by installing the Power Platform Pipelines app on an existing Dataverse env. | A regular Dataverse env in the tenant | D365_ProjectHost (or app-installed-onto-existing-env) |
| No host bound to source env | Tenant has not used Pipelines from this env. | — | — |
The current discover-pipelines-host.js only checks the tenant-level DefaultCustomPipelinesHostEnvForTenant setting. That's one signal of many. This skill implements the full resolution order.
Resolution order (mirrors ProjectHostProvider.tsx)
This is the load-bearing decision tree. It is what the Power Apps UI does. We replicate it so the skill agrees with the UI.

What this skill does NOT do
These are deliberate non-goals (each based on a hard constraint or a destructive blast-radius — see Design Constraints below):
- Does not silently provision anything. Any action that creates an env or binds the source env to a host requires explicit user confirmation, with the tenant name + tenant ID echoed back. PE is tenant-singleton and admin-non-deletable, so the Phase 4.0 pre-call confirmation gate is the principal mitigation against wrong-tenant provisioning. The
getOrCreate endpoint is idempotent — calling it on a tenant that already has a PE returns the existing one rather than creating a duplicate.
- Does not call
Force Link to rebind an environment to a different host. Force Link is destructive (makers lose access to existing pipelines in the previous host) and is hidden behind a separate confirmation gate, only reachable when the user explicitly says "rebind".
- Does not change the tenant-level
DefaultCustomPipelinesHostEnvForTenant setting. That setting is irreversible-adjacent (existing pipelines in the previous default become inaccessible — see learn.microsoft.com/power-platform/alm/set-a-default-pipelines-host). Out of scope.
- Does not delete environments.
- Does not write
ProjectHostEnvironmentId directly. Binding is established through the documented Pipelines flow (creating a deploymentenvironment record in the host); writing the org setting directly bypasses validation.
Auth strategy: PAC-first with BAP fallback (--source auto)
Read-side detection (Phase 2 resolution order, env list, env-by-id) defaults to --source auto:
- If a BAP token is provided, try BAP env-list / env-GET first (richer data including
lastModifiedTime, permissions, tenantId).
- On HTTP 401 or 403, fall back to
pac admin list --json via pac-bap-shim.js. PAC has its own first-party client-ID grants on BAP that Az CLI doesn't always inherit (verified 2026-04-28: D365DemoTSCE53051106 demo tenant rejects Az tokens for BAP even with correct audience claims).
- If no BAP token is provided at all, go straight to PAC.
The PAC shim returns BAP-shaped data; downstream code (sku filter, ranking, classification) is unchanged. Fields not provided by PAC (tenantId, lastModifiedTime, permissions, isManaged) come back as null — none are critical for host detection. PAC also doesn't surface Platform Hosts (PE) since pac admin list doesn't include Platform-sku envs; PE detection requires --source bap with a working BAP token.
Write-side actions (env-create POST in provision-custom-host.js, lifecycle op polling) still require BAP. Az CLI tokens with the right audience usually work for these even when env-list calls fail, because the BAP RP enforces different policy on actions than reads. If provision-custom-host.js returns 401, the user must register a service principal in the target tenant (or use the PPAC UI fallback path 4.C).
Design Constraints
- JIT provisioning is required when a PE is selected — existing or freshly provisioned. From
ProjectHostProvider.tsx (line 232–240 comment): "In the Platform Environment case, the user may not already be provisioned there, so BAP cannot discover it. So we'll use the org URL we retrieve from the getOrCreate call to make this first request so that user JIT can be triggered." When Phase 2 detects an existing PE and the user accepts it (Phase 3.A) — or when Phase 4.0 provisions a new PE via getOrCreate — Phase 5's WhoAmI call against instanceApiUrl triggers JIT before any subsequent host op. (For Custom Host paths the caller has access by construction.)
CannotRedirect is a real terminal state, not a theoretical edge case. It happens when ProjectHostEnvironmentId (org setting on source env) points at PE but DefaultCustomPipelinesHostEnvForTenant (admin tenant setting) points elsewhere. The skill must detect this and surface it as a specific error — falling through silently would route pipeline ops at the wrong host.- Admin-only Custom Host fast-path. PPAC's
New custom host flow is gated by DeploymentHubCreatePipelinesHostForAdminsOnly and shows only for Global / Power Platform / Dynamics admins (eng.ms doc). The BAP env-create API also needs the equivalent privilege. Non-admins get 403; the skill preflight-attestation-prompts and gracefully falls back to manual paths.
- 404 from BAP env GET is ambiguous. Returns 404 for deleted, disabled, no-PE, and no-access without distinguishing (
PowerPipelines_PE_Knowledge.md §6.A). We never treat a single 404 as "no host exists" — we corroborate via list-environments and the org setting before acting.
- Each environment is bound to only one host at a time. Rebinding requires Force Link, which is destructive in the previous host. Out of scope (see non-goals).
- The skill runs in user OAuth context — same scope and audience the Power Apps UI uses. BAP calls use
https://service.powerapps.com/ audience.
Idempotency of getOrCreate — the BAP getOrCreate endpoint is idempotent (existing PE returns 200 + provisioningState === 'Succeeded'; new PE returns 202 + lifecycle op). Phase 4.0 leverages this — calling getOrCreate on a tenant that already has a PE is safe and just returns the existing one. The provision-platform-host.js helper surfaces the distinction via an alreadyExisted: true | false flag in its return value (recorded in the docs/alm/last-host-check.json telemetry block as platformHostAlreadyExisted).
Prerequisites
- PAC CLI logged in (
pac env who succeeds)
- Azure CLI logged in (
az account show succeeds)
- A source Dataverse environment URL (read from
powerpages.config.json if invoked from a Power Pages project; passed as arg otherwise)
- For Phase 4 admin-only paths: caller has Global / Power Platform / Dynamics admin (skill detects and surfaces 403 cleanly if missing)
Phases
Phase 1 — Detect prerequisites and gather tenant context
Create all tasks upfront at the start of this phase.
Tasks to create:
- "Check local cache and detect prerequisites"
- "Run resolution order to find host"
- "Confirm action with user"
- "Execute chosen path"
- "JIT-provision and verify host"
- "Write host-check artifact"
Steps:
-
Local cache fast-path. If docs/alm/last-host-check.json exists AND Date.now() - Date.parse(checkedAt) < cacheMaxAgeMs (default 24h; configurable via --cacheMaxAgeHours):
- Acquire
HOST_TOKEN for the cached finalHostEnvUrl origin.
- One cheap probe:
GET {finalHostEnvUrl}/api/data/v9.0/solutions?$filter=uniquename eq 'msdyn_AppDeploymentAnchor'&$select=version&$top=1 (proves Pipelines is installed AND captures version in one round-trip)
- 200 → cache is valid. Set
RESOLUTION from the cached file. Set ACTION_TAKEN = "none". Skip Phases 2–5; jump to Phase 6 with a "reused cached host" summary.
- 404 / 403 / timeout / network → cache is stale or no longer accessible. Continue to Step 1 (full resolution). Do NOT fail — stale cache is expected after env deletion or permission changes.
- If the file is missing, malformed, older than
cacheMaxAgeMs, or contains ready: false → continue to Step 1.
- Skip this step entirely if
--no-cache is passed (used in CI / smoke tests).
-
Run verify-alm-prerequisites.js:
node "${PLUGIN_ROOT}/scripts/lib/verify-alm-prerequisites.js"
Capture .envUrl (devEnvUrl), .token (DEV_TOKEN), .userId, .tenantId, .organizationId. Stop on auth failure with the script's remediation message.
-
Run detect-project-context.js (non-fatal — skill is also valid outside a Power Pages project):
node "${PLUGIN_ROOT}/scripts/lib/detect-project-context.js"
Capture .siteName and .solutionManifest for messaging.
-
Acquire BAP token (different audience than Dataverse):
az account get-access-token --resource "https://service.powerapps.com/" --query accessToken -o tsv
3a. Resolve tenant display name (one-shot, best-effort). Phase 1.4 and Phase 4.0 echo a human-readable tenant name alongside the tenant GUID so the user can verify the target tenant. Acquire it from the Microsoft Graph organization endpoint:
az rest --method GET --url "https://graph.microsoft.com/v1.0/organization?$select=id,displayName" --resource "https://graph.microsoft.com/" --query "value[0].displayName" -o tsv
Store as TENANT_DISPLAY_NAME. On any failure (no Graph permission, network error, multi-tenant ambiguity), fall back to TENANT_DISPLAY_NAME = null and continue — Phase 1.4 / 4.0 prompts handle a null display name by showing the tenant GUID alone.
🚦 Gate (consent · ensure-pipelines-host:1.4.tenant-identity): Echo tenant display name + tenant GUID + dev env URL before any host detection. First of the wrong-tenant guards. Cancel exits cleanly before any BAP/Dataverse call.
-
Tenant identity confirmation gate. Echo back via AskUserQuestion:
"About to inspect Pipelines host configuration for tenant {TENANT_DISPLAY_NAME} ({tenantId}), org {organizationId}, dev env {devEnvUrl}. Continue? 1. Yes / 2. Cancel"
(When TENANT_DISPLAY_NAME is null, drop the bold tenant-name segment and lead with the tenant GUID.)
First of the consent gates that guard against wrong-tenant operations.
Phase 1.5 — Ground in current Pipelines host documentation
Reference: ${PLUGIN_ROOT}/references/alm-docs-grounding.md
Cap this step at ~30 seconds. If MCP search / fetch errors out, log a one-line note and continue — this skill must remain runnable offline.
- Run
microsoft_docs_search with the query: Power Platform Pipelines host environment Platform Host Custom Host.
- Fetch
https://learn.microsoft.com/en-us/power-platform/alm/pipelines (and at most one sister page on host setup, default-custom-host configuration, or admin role requirements) in parallel via microsoft_docs_fetch.
- Extract a one-paragraph summary of what Microsoft Learn currently says about Platform vs Custom Host trade-offs, the resolution order (org-db setting → BAP env metadata → tenant default), and admin role requirements. Compare against this skill's own Resolution order section and
${PLUGIN_ROOT}/references/cicd-pipeline-patterns.md; flag any divergence (e.g. new Platform-Host SKU, changed default-custom-host setting name, new tenant policy controls).
- Use the summary to inform Phase 2+ decisions. Do not silently change skill behavior — surface any divergence to the user as a soft warning before Phase 3 (Confirm action with user).
Phase 2 — Run resolution order to find host
This phase is read-only. It produces a RESOLUTION object the user-confirm phase branches on.
The phase mirrors ProjectHostProvider.tsx exactly. The useState variables in that hook map to fields in our RESOLUTION:
| TS variable | Our field |
|---|
orgSetting.orgDbOrgSettingValue | orgSettingHostEnvId |
initialProjectHostEnvironmentId | (same) |
isInitialHostPlatformEnvironment | isPlatform |
defaultCustomPipelinesHost | tenantDefaultCustomHostEnvId |
finalProjectHostEnvironmentId | finalHostEnvId |
projectHostStatus | status |
Steps:
-
Org-setting probe (mirrors useGetOrgDbOrgSetting('ProjectHostEnvironmentId') line 103 in tsx). New helper check-env-host-binding.js:
POST {devEnvUrl}/api/data/v9.0/GetOrgDbOrgSetting
Authorization: Bearer {DEV_TOKEN}
Body: { "SettingName": "ProjectHostEnvironmentId" }
- Empty
SettingValue → no current binding. Skip to Step 4.
- Non-empty → store as
orgSettingHostEnvId. Continue to Step 2.
-
Resolve env via BAP (mirrors useGetEnvironmentByName(initialProjectHostEnvironmentId) line 483 in tsx). New helper resolve-env-by-id.js:
GET https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/environments/{envId}?api-version=2020-06-01&$expand=properties.linkedEnvironmentMetadata,properties.permissions
Authorization: Bearer {BAP_TOKEN}
- 200 → capture
environmentSku, displayName, linkedEnvironmentMetadata.instanceApiUrl, linkedEnvironmentMetadata.instanceUrl. Set RESOLUTION.isPlatform = (environmentSku === 'Platform').
- 404 → disambiguate before acting (Constraint 5). Run
list-tenant-envs.js (Step 5) and check whether the env is in the list:
- If listed → user lacks access → set
RESOLUTION.status = "PermissionDenied", surface to user, stop.
- If not listed → env is genuinely deleted/disabled → set
RESOLUTION.status = "OrgSettingStale", recommend the user clear ProjectHostEnvironmentId and re-run, stop.
- 403 → set
RESOLUTION.status = "PermissionDenied", stop.
-
If isPlatform === true, mirror the default-custom-tenant-setting check (lines 148–213 in tsx). Reuse the existing discover-pipelines-host.js:
node "${PLUGIN_ROOT}/scripts/lib/discover-pipelines-host.js" \
--envUrl "{devEnvUrl}" --token "{DEV_TOKEN}" --userId "{userId}"
found: false → tenant has no admin default custom host. (the PE). Set .
Report findings to user:
"Tenant {tenantId} host status: {RESOLUTION.status}. {Status-specific summary line.}"
Phase 3 — Confirm action with user
Branches by RESOLUTION.status. Each branch ends with either "proceed to Phase 5" (host already usable) or "Phase 4 with chosen path".
3.A — Status AvailableUsingCustomHost / AvailableUsingCustomHostByAdminDefault / AvailableUsingPlatformHost
Host is established. Confirm and skip ahead.
"Found existing host: {finalHostEnvUrl} ({RESOLUTION.status}, Pipelines solution v{PIPELINES_SOLUTION_VERSION}). Use this host?
- Yes — proceed to verification
- Cancel"
- Yes → set
ACTION_TAKEN = "none", jump to Phase 5.
- Cancel → exit.
3.B — Status CannotRedirect
Locked state. Cannot proceed.
"Cannot proceed: ProjectHostEnvironmentId on {devEnvUrl} points at the Platform Host ({orgSettingHostEnvId}), but the tenant admin set DefaultCustomPipelinesHostEnvForTenant to a different env ({tenantDefaultCustomHostEnvId}). The Pipelines UI cannot redirect this env to the admin's choice. Resolution requires a Power Platform admin to either (a) clear the tenant default, or (b) update the org setting on this env. Exiting."
Stop.
3.C-pre — Status AvailableUnboundCustomHost (single existing Custom Host found)
Tenant already has exactly one Custom Host with Pipelines installed. Source env isn't bound to it yet, but binding happens automatically when setup-pipeline registers the source env in the host's deploymentenvironments table. Reusing avoids creating duplicate hosts.
"Found an existing Custom Host in tenant {tenantId}:
- Display name:
{displayName}
- URL:
{instanceApiUrl}
- Pipelines solution: v
{pipelinesSolutionVersion}
Source env {devEnvUrl} is not yet bound to it — that will happen automatically the first time setup-pipeline runs against this host. Use this host?
- Yes — use existing host (recommended; avoids duplicates)
- No — show me the create-new decision tree (Phase 3.C)
- Cancel"
- Yes → set
finalHostEnvUrl/Id, ACTION_TAKEN = "reuse-existing-custom", jump to Phase 5.
- No → fall through to Phase 3.C
NoHost decision tree (still allows creating another).
- Cancel → exit.
3.C-pre' — Status MultipleUnboundCustomHosts (multiple existing Custom Hosts found)
"Found {N} existing Custom Hosts in tenant {tenantId} with Pipelines installed. Pick one to use, or create new:
{host[0].displayName} ({host[0].instanceApiUrl}, Pipelines v{host[0].pipelinesSolutionVersion}){host[1].displayName} (...)
...
N. ...
N+1. Create new Custom Host instead — go to Phase 3.C decision tree
N+2. Cancel"
- Selection 1..N → set
finalHostEnvUrl/Id from picked host, ACTION_TAKEN = "reuse-existing-custom", jump to Phase 5.
- N+1 → fall through to Phase 3.C
NoHost decision tree.
- N+2 → exit.
3.C-pre'' — Status PlatformHostExistsUnbound (PE already exists, no Custom Host)
A PE already exists in the tenant (one is provisioned automatically the first time anyone navigated to the Pipelines page). Per scope decision, this iteration does NOT auto-provision a PE, but if one already exists, we offer to use it.
"Tenant {tenantId} already has a Platform Host ({instanceApiUrl}, Pipelines v{pipelinesSolutionVersion}). Source env is not yet bound to it. Use this host?
- Yes — use existing Platform Host (idempotent — already provisioned in this tenant)
- No — create a Custom Host instead (Phase 3.C decision tree)
- Cancel"
- Yes → set
finalHostEnvUrl/Id from PE, ACTION_TAKEN = "reuse-existing-pe", jump to Phase 5. (Phase 5's WhoAmI call triggers JIT — Constraint 1.)
- No → fall through to Phase 3.C
NoHost decision tree (admin-created Custom Host preferred for governance).
- Cancel → exit.
3.C — Status NoHost (host-type decision tree)
🚦 Gate (plan · ensure-pipelines-host:3.C.host-type): Top-level host-type prompt — pick Platform Host / Custom Host / PPAC manual / Manual export-import strategy / Cancel. Drives the rest of Phase 3 and Phase 4 routing.
Trigger: Status NoHost AND no upstream hostResolution.willProvision* flag carries the answer.
Why we ask: Auto-picking provisions an env (PE or Custom Host) without consent; PE is tenant-singleton and admin-non-deletable.
Cancel leaves: Nothing — no provisioning fired yet.
🚦 Gate (plan · ensure-pipelines-host:3.C.env-pick): Sub-prompt under 3.C top-level option "Custom Host" — present the eligible-env list (capped at 5) with role labels (dev env, source env, staging env, production env) and the "Other (paste URL)" fallback. Fires only on the Custom-Host branch of the host-type menu.
Trigger: User picked "Custom Host" in 3.C top-level.
Why we ask: Auto-picking the wrong env routes pipelines through a host the user didn't intend.
Cancel leaves: Nothing — no app install fired.
The prompt asks the user to pick the host type first (Platform Host, Custom Host, PPAC manual, or cancel). Picking Custom Host opens a sub-prompt for the install method (existing env vs. create-new). The Platform-Host path is the lowest-friction default and is presented first.
Skip rule — caller already collected the answer. When this skill is invoked from setup-pipeline and docs/alm/last-pipeline.json carries a hostResolution block populated by plan-alm Phase 2 Q4, inspect those flags before showing the prompt:
| Upstream signal | Action |
|---|
hostResolution.willProvisionPlatform === true | Skip Phase 3.C entirely. Route directly to Phase 4.0 (provision new Platform Host). The pre-call confirmation gate in 4.0 still runs — see 4.0 "Pre-call confirmation (NON-SKIPPABLE)" below. |
hostResolution.chosenEnvUrl is a non-empty URL | Skip Phase 3.C entirely. Set CHOSEN_ENV_URL = hostResolution.chosenEnvUrl, route directly to Phase 4.B with that env (4.B step 1's "already chosen" path applies). Set ACTION_TAKEN per the existing routing table ("user-installed-app-on-dev" when origin matches devEnvUrl, else "user-installed-app"). |
hostResolution.willProvisionCustom === true AND chosenEnvUrl empty | Skip Phase 3.C. Route directly to Phase 4.A (provision new Custom Host). The pre-call confirmation gate in 4.A still runs. |
hostResolution.willUsePpac === true AND chosenEnvUrl empty | Skip Phase 3.C. Route directly to Phase 4.C (PPAC manual). |
| None of the above | Run Phase 3.C as written below. |
Why this skip rule exists. plan-alm Phase 2 Q4 NoHost branch presents the same host-type menu so the user makes the choice once, at planning time, with the rendered ALM plan in front of them. Re-prompting in 3.C at execution time would force a second answer to the same question and risks the agent treating one of the answers as authoritative and ignoring the other (the bug behind the trial-license-409 → wrong-env-fallback chain that surfaced on 2026-05-05). Whenever the upstream signal is present, trust it.
Step 1: present the top-level host-type prompt.
"No Pipelines host bound to {devEnvUrl}. Which environment should host Pipelines?
Pipelines lives in one env per tenant; pipelines, stages, and run history are stored there. Source envs deploy through it.
-
Provision a Platform Host (recommended) — Microsoft-managed Dataverse env auto-provisioned in your tenant home geo. Pipelines app pre-installed. Idempotent (safe to re-run). ~3–5 min.
-
Set up a Custom Host — Pipelines lives in a Dataverse env you control. We'll ask whether to use an existing env or create a brand-new dedicated one.
-
Open PPAC and create one manually — fallback if option 2 doesn't work for you.
-
Cancel — exit."
Top-level routing:
| Selection | Action |
|---|
| Option 1 | Phase 4.0 (with pre-call confirmation gate). ACTION_TAKEN = "fast-path-platform-getorcreate". |
| Option 2 | Show the Custom-Host sub-prompt at Step 2 below. |
| Option 3 | Phase 4.C. ACTION_TAKEN = "user-created-custom-ppac". |
| Option 4 | Exit. |
Step 2: build the eligible-env list and apply role labels (only needed when the user picks Option 2 → sub-option a; do this lazily after Option 2 is selected).
Take RESOLUTION.candidates.eligibleForAppInstall[] from Phase 2 (envs with Dataverse, caller has access, Pipelines NOT yet installed, sku ∈ default filter — {Production, Sandbox}; widen to Production,Sandbox,Trial via --skus for trial-license tenants).
For each entry, decorate with project-context labels at presentation time. Match by URL origin (lowercase, trailing slash stripped, path/query ignored). Multiple labels join with ·.
| Label | Source signal |
|---|
dev env | The env URL the skill is running against (devEnvUrl from caller / pac env who) |
source env | sourceEnvironmentUrl from docs/alm/last-pipeline.json (typically same env as dev) |
staging env | targetEnvironmentUrl of any stage in docs/alm/last-pipeline.json whose stage name matches /stag|test|uat/i |
production env | targetEnvironmentUrl of any stage whose name matches /prod/i |
Envs with no role match show without a label.
Step 2a: rank and cap the eligible-env list. AskUserQuestion becomes unusable past about 7–8 options. Apply a 5-env presentation cap with role-aware ranking:
- Always-visible role-labeled envs (highest priority): include any eligible env that carries a
dev env, source env, staging env, or production env label from Step 2's role decoration. Dedupe by URL origin.
- Fill remaining slots up to 5 from the rest of the eligible list, in
list-tenant-envs.js's native order (name-hint pattern → admin-perms → lastModifiedTime).
- Always append an "Other (paste URL)" entry as the last item.
Track the total eligible count separately — when eligible.length > 5, surface the gap inline.
Step 2b: empty-list collapse. If the eligible list has zero entries after the filters, first try widening the SKU filter to include Trial (re-invoke ensure-pipelines-host-detect.js with --skus Production,Sandbox,Trial). If still zero, drop sub-option a from the Custom-Host sub-prompt — present only b (create new) and c (Back). Print the SKU-filter detail so the user can override:
"No existing environments matched the SKU filter (Production, Sandbox, Trial). Run --skus <comma-list> to widen further, or pick b to create a brand-new env, or c to go back."
Step 2c: present the Custom-Host sub-prompt (when user picks Option 2):
"How would you like to set up the Custom Host?
a. Use an existing environment — install the Pipelines app on it.{eligibleCountSuffix} Pick from your eligible envs:
{env[0].displayName} ({env[0].instanceApiUrl}) — {environmentSku} — {labels if any}{env[1].displayName} (...)- … (up to 5 entries)
- Other (paste URL) — for any eligible env not on this short list
⚠ Sandbox-sku envs trigger a confirmation prompt before install.
b. Create a brand-new dedicated env — automated env-create with template D365_ProjectHost. Pipelines app pre-installed. Requires Global / Power Platform / Dynamics admin. ~5–10 min.
c. Back — return to the top-level host-type menu."
{eligibleCountSuffix} substitution rules:
eligible.length <= 5 → empty string (no suffix; all envs visible).eligible.length > 5 → Showing top 5 of {N}; the remaining {N-5} eligible env(s) can be reached via the "Other (paste URL)" entry. (leading space).
When the user picks "Other (paste URL)", pre-fill the URL input with the environment list from node "${PLUGIN_ROOT}/scripts/lib/list-environments.js" (parses pac env list into JSON { displayName, environmentId, environmentUrl, uniqueName, active }; the old pac env list --output json is invalid on current PAC CLI) so they can paste-or-pick from the inventory rather than typing a URL by hand.
Test scenarios to verify when changing this prompt:
- 0 eligible → sub-option
a dropped (sub-prompt shows only b / c).
- 1–5 eligible → list all inline, no suffix.
- 6+ eligible with role-labeled envs (dev/staging/prod) present → all role-labeled envs surface first; remaining slots filled by ranking; suffix shows count gap.
- 6+ eligible with NO role-labeled envs → top 5 by ranking; suffix shows count gap.
Step 3: route the sub-prompt answer.
| Selection | Phase 4 path | ACTION_TAKEN |
|---|
| Option 1 (top-level Platform Host) | 4.0 (pre-call confirmation, then provision-platform-host.js) | "fast-path-platform-getorcreate" |
Option 2 → sub-option a — picked env from list, URL matches devEnvUrl (origin-equal) | 4.B (skip the "which env" sub-prompt; pass the picked env URL through as CHOSEN_ENV_URL) | "user-installed-app-on-dev" |
Option 2 → sub-option a — picked any other listed env | 4.B (skip sub-prompt; pass CHOSEN_ENV_URL) | "user-installed-app" |
Option 2 → sub-option a — "Other (paste URL)" | 4.B with user-supplied URL as CHOSEN_ENV_URL | "user-installed-app" |
Option 2 → sub-option a — picked env where environmentSku === "Sandbox" | Step 4 Sandbox confirmation gate, then 4.B if confirmed | (deferred until confirmation) |
Option 2 → sub-option b | 4.A (sub-prompts: name, region, admin confirmation) | "fast-path-custom-d365projecthost" |
Option 2 → sub-option c (Back) | re-show top-level menu | n/a |
| Option 3 | 4.C | "user-created-custom-ppac" |
| Option 4 | exit | n/a |
For Option 1 and sub-option b, a non-skippable pre-call confirmation gate echoes the tenant identity before firing. Option 1 → see Phase 4.0 "Pre-call confirmation". Sub-option b → see Phase 4.A "Pre-call confirmation (NON-SKIPPABLE)".
Step 4 (conditional): Sandbox confirmation gate.
If the env picked in sub-option a has environmentSku === "Sandbox", present:
"⚠ {displayName} is a Sandbox env (environmentSku: Sandbox).
Power Platform Pipelines is documented to run on Production envs. Sandbox should work but isn't on the supported matrix.
Proceed?
- Yes, proceed at my own risk
- Pick a different env
- Cancel"
- Yes → continue to 4.B with the Sandbox env. Set
ACTION_TAKEN per the dev-env-match rule above.
- Pick a different env → re-show sub-option
a's env list (keep the rest of the picker state).
- Cancel → back to the top-level Phase 3.C prompt.
Telemetry note. Splitting "user-installed-app" and "user-installed-app-on-dev" lets us see, after rollout, how often users co-locate Pipelines with their dev env vs. dedicating a separate env. The new "fast-path-platform-getorcreate" value lets us measure adoption of the new lowest-friction path; the telemetry.platformHostAlreadyExisted flag in the artifact distinguishes idempotent-existing (200) from newly-provisioned (202) outcomes — useful for tuning Phase 2.5's --maxEnvsToProbe defaults if we see Phase 4.0 hitting 200 frequently.
3.D — Status HostWithoutPipelines (rare)
Host env exists but Pipelines solution is missing.
"Found host environment {finalHostEnvUrl} but the Pipelines solution is not installed. Install it now via PPAC?
- Yes — open PPAC and install (guided manual)
- No — exit"
- Yes → Phase 4.C with pre-selected env.
- No → exit.
3.E — Status OrgSettingStale / PermissionDenied
Surface the specific failure to the user. Out of automated remediation scope. Recommend manual cleanup.
Phase 4 — Execute chosen path
4.0 — Fast-path: Platform Host via getOrCreate
🚦 Gate (consent · ensure-pipelines-host:4.0.pre-call): Echo the tenant identity in the request body before firing the BAP getOrCreate Platform Host call. NON-SKIPPABLE even when upstream hostResolution.willProvisionPlatform === true. PE is tenant-singleton and admin-non-deletable — this gate is the principal wrong-tenant mitigation.
Trigger: Phase 4.0 entry (routed in from 3.C or upstream).
Why we ask: PE provisioned in wrong tenant; cannot be deleted by tenant admin.
Cancel leaves: Nothing — no provisioning fired yet.
The lowest-friction host-provisioning path. Calls the idempotent BAP getOrCreate endpoint with a D365_1stPartyAdminApps + Platform body. Same call make.powerapps.com → Pipelines page makes when a user clicks "Get started" — we just invoke it directly. Spec from useGetOrCreatePlatformEnvironment.v4.ts. New helper provision-platform-host.js.
No sub-prompts. BAP picks tenant home geo + default display name; no admin role required.
Pre-call confirmation via AskUserQuestion — NON-SKIPPABLE single consent gate:
"About to provision a Platform Host for tenant {TENANT_DISPLAY_NAME} ({tenantId}).
A Platform Host is a Microsoft-managed Dataverse environment in your tenant's home region. One per tenant, idempotent — if you already have one, it'll be returned. New provisioning takes about 3–5 minutes.
Proceed? 1. Yes / 2. Cancel"
(When TENANT_DISPLAY_NAME is null, drop the bold tenant-name segment and lead with the tenant GUID.)
Why this gate runs even when upstream hostResolution.willProvisionPlatform === true — same rationale as 4.A's pre-call gate: this echoes the exact tenant identity, the user's last chance to catch a wrong-tenant operation. PE is tenant-singleton and admin-non-deletable; the gate is the principal mitigation. Implementation details (BAP endpoint, body shape) are intentionally kept out of the user-facing prompt and live in this SKILL.md / provision-platform-host.js source.
Call:
node "${PLUGIN_ROOT}/scripts/lib/provision-platform-host.js" \
--bapToken "{BAP_TOKEN}" \
--correlationId "{uuid v4}"
Response handling (delegated to the helper, but the routing decision lives here):
200 + properties.provisioningState === 'Succeeded' → tenant already had a PE (idempotent path). Helper returns { status: 'Succeeded', alreadyExisted: true, instanceApiUrl, ... }. Set RESOLUTION.finalHostEnvUrl, finalHostEnvId, RESOLUTION.isPlatform = true, actionTaken = "fast-path-platform-getorcreate", telemetry.platformHostAlreadyExisted = true. Continue to Phase 5. Defensive note: this means Phase 2.5 enumeration missed the PE (probably because --maxEnvsToProbe capped before the PE was reached, or a race between Phase 2 and 4.0). Surface a debug-level note; don't fail.202 + Location → helper polls until provisioningState === 'Succeeded' and returns { status: 'Succeeded', alreadyExisted: false, instanceApiUrl, ... }. Set the same fields with telemetry.platformHostAlreadyExisted = false.403 → helper throws with the BAP body verbatim; recommend az logout && az login. Offer fallback to Options 2/3/4. (Do NOT reuse the 4.A admin-required copy — getOrCreate does not require admin.)4xx / 5xx other → helper throws; surface, ask retry or switch path.
On success: RESOLUTION.isPlatform = true (so Phase 5 takes the JIT branch — Constraint 1). Proceed to Phase 5.
4.A — Fast-path: Custom Host via D365_ProjectHost template
🚦 Gate (consent · ensure-pipelines-host:4.A.pre-call): Echo the BAP env-create request body (region + display name + template) before firing the Custom Host create call. NON-SKIPPABLE even when upstream hostResolution.willProvisionCustom === true. Last chance to catch a wrong-tenant/wrong-region provisioning. Bug fixed 2026-05-05 was caused by skipping this gate.
Trigger: Phase 4.A entry; sub-prompts (display name, region, admin attestation) collected.
Why we ask: Custom Host provisioned in wrong tenant or wrong region; consumes Azure capacity quota; potentially attributes the env to the wrong organization.
Cancel leaves: Nothing — no provisioning fired yet.
🚦 Gate (consent · ensure-pipelines-host:4.sandbox-confirm): When the picked install-target env has environmentSku=Sandbox, surface the sandbox-limits warning and require explicit re-confirmation before installing. Fires once per Sandbox-SKU env selected.
Trigger: Phase 4.B / Phase 3.C sub-option a — picked env is Sandbox SKU.
Why we ask: Installing Pipelines onto a Sandbox env without consent — sandbox envs are deletable on inactivity and have reduced capacity; pipelines may break unexpectedly.
Cancel leaves: Nothing — no app install fired.
Standard env-create API with the D365_ProjectHost template (eng.ms-documented; same template PPAC New custom host uses internally). New helper provision-custom-host.js.
Sub-prompts (collected before the API call) via AskUserQuestion:
- Display name (default suggestion:
"{tenant displayName} Pipelines Host")
- Region (default: tenant home geo from BAP
tenant endpoint; offer override)
- Confirm caller is admin — single AskUserQuestion "Are you a Global / Power Platform / Dynamics admin in this tenant? Yes / No / Not sure". If No or Not sure, recommend Path 4.B/4.C and fall back.
Pre-call confirmation via AskUserQuestion — NON-SKIPPABLE second consent gate:
"About to call POST https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/environments?api-version=2021-04-01 for tenant {tenantId} with body:
{
"location": "{region}",
"properties": {
"displayName": "{display name}",
"environmentSku": "Production",
"databaseType": "CommonDataService",
"linkedEnvironmentMetadata": { "templates": ["D365_ProjectHost"] }
}
}
Provisions a Custom Host with the Pipelines app pre-installed (~5–10 min). Proceed? 1. Yes / 2. Cancel"
This gate must always run. Do NOT skip it because plan-alm Q4 already received a "continue with PP Pipelines" confirmation, or because hostResolution.willProvisionCustom === true upstream, or because the user said yes to the admin attestation moments earlier. plan-alm Q4 and the admin attestation are about strategy; this gate echoes the exact API call body (URL, region, tenant, template) and is the user's last chance to catch a wrong-tenant or wrong-region provisioning. The bug fixed on 2026-05-05 surfaced precisely because the agent treated the plan-alm pre-confirmation as covering this gate.
Call:
POST https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/environments?api-version=2021-04-01

}
Response handling:
202 + Location header + Retry-After header → poll the Location URL until lifecycle op completes.200 + immediate body (rare for env-create) → capture URLs.403 from initial POST → stop with "Custom Host fast-path requires Global / Power Platform / Dynamics admin. Suggest Path 2 (Pipelines app on existing env) if you have system-admin on a Dataverse env, or Path 3 (PPAC UI) if you can request admin assistance." Offer seamless fallback to 4.B / 4.C.409 with a capacity-related code (e.g. NotEnoughCapacity_HasTrialLicense_ProvisionEnvironment, NotEnoughCapacity, NotEnoughCapacity_OrganizationDisabled, EnvironmentCapacityExceeded) → offer a SKU-fallback prompt before falling back to Path 4.B. The license / capacity constraint usually applies only to the requested SKU; smaller SKUs (Sandbox, Developer, Trial) often succeed on the same tenant and produce a Pipelines host that works identically (the Pipelines app installs on any SKU — only license allocation differs). See sub-step "4.A — SKU fallback prompt" below. Only after the user declines a SKU fallback OR the fallback also fails should we re-enter Phase 3.C / Path 4.B.- 4xx / 5xx other → surface error, ask user to retry or switch path. On switch to 4.B, follow the same "use original eligible-env list" rule above.
Polling:
GET {Location}
Authorization: Bearer {BAP_TOKEN}
Interval = Retry-After seconds (default 10s). Timeout = 15min (configurable). On each response, read provisioningState (and/or operation state field — confirm during execution):
Creating / InProgress → continue pollingSucceeded → done; capture instanceApiUrl, name (env GUID), displayNameFailed / Canceled → surface error, stop
On success: set RESOLUTION.finalHostEnvUrl, finalHostEnvId, instanceApiUrl, actionTaken = "fast-path-custom-d365projecthost". Proceed to Phase 5.
4.A — SKU fallback prompt (capacity-error remediation)
When env-create returns a 409 capacity-related error, the user's tenant doesn't have spare license/capacity for the requested SKU but may have it for a smaller SKU. Surface the constraint clearly and offer fallback SKUs before suggesting Path 4.B:
-
Read the error body. Extract:
error.code (e.g. NotEnoughCapacity_HasTrialLicense_ProvisionEnvironment)error.message (the human-readable explanation from BAP, e.g. "Trial licenses are limited to creating Trial environments only.")
-
Build the fallback SKU list. The default order is Production (recommended) → Sandbox → Developer → Trial, dropping the SKU that just failed. Each SKU carries a different caveat:
| SKU | When to suggest | Caveat to surface |
|---|
Production | Default first choice | None — the documented Pipelines host SKU |
Sandbox | Tenants with subscription but no spare Production capacity | "Sandbox SKU works for Pipelines but is documented as non-production. Microsoft may apply different SLAs to Sandbox-hosted apps." |
Developer | Individual-developer tenants | "Developer SKU is single-user. Other team members will not be able to deploy through this host. Use only if this is a personal/dev-only ALM setup." |
Trial | Trial-license tenants (no other option works) | "Trial environments expire after 30 days unless converted. The Pipelines host will need to be re-provisioned at expiry." |
-
Tell the user the constraint and present the prompt:
"Custom Host provisioning failed with {error.code}: {error.message}
The Pipelines app installs identically on any SKU — only the license allocation differs. You can retry env-create with a smaller SKU, or fall back to installing the Pipelines app on an existing env (Path 4.B)."
🚦 Gate (plan · ensure-pipelines-host:4.A.sku-fallback): Capacity error on env-create — retry with different SKU, fall back to Path 4.B (install on existing env), or cancel.
AskUserQuestion (build the option list dynamically — drop the SKU that just failed, append the caveats inline):
| Question | Header | Options |
|---|
| Retry env-create with a different SKU? |
4.B — Install Pipelines app on an existing env (automated)
This path was previously a manual click-through to PPAC. As of 2026-05-08 it's fully automated: install-pipelines-app.js calls the BAP applicationPackages/install endpoint (the same API that backs PPAC's "Install app" button) and falls back to pac application install when BAP returns 401/403/5xx.
Sub-prompt: pick the target env (skipped when env is already chosen):
-
If the env was already chosen (CHOSEN_ENV_URL is set, either from Phase 3.C Option 2 → sub-option a OR from the upstream skip rule on hostResolution.chosenEnvUrl): skip the sub-prompt — proceed directly to the install step with the chosen env. Set ACTION_TAKEN per the Phase 3.C Step 3 routing table ("user-installed-app-on-dev" when CHOSEN_ENV_URL origin matches devEnvUrl, else "user-installed-app").
Otherwise (legacy entry path — caller invoked 4.B directly without going through 3.C, or arrived here via the 4.A failure fallback): present the sub-prompt "Which env will host Pipelines? (Auto-detected envs from Phase 2 inventory):" with the eligible-for-app-install list from RESOLUTION.candidates.eligibleForAppInstall[] as choices, plus "Other (paste URL)". When arriving from 4.A's 409 trial-license fallback, the eligible list still applies — discard any env GUID surfaced in the 409 response body.
Env GUID sanity check. The GUID passed to the install helper must come from the chosen env's name field as enumerated in Phase 2 (or from pac env list for a user-pasted URL). Never substitute a GUID from a 4.A failure response, from docs/alm/last-host-check.json of a different run, or from any other state path. If you cannot determine the GUID with confidence, ask the user to confirm via AskUserQuestion showing the env display name + URL + GUID before invoking the helper.
Pre-call confirmation gate (NON-SKIPPABLE — same rationale as Phase 4.0 / 4.A):
"About to install the Power Platform Pipelines application on {displayName} ({instanceApiUrl}) in tenant {TENANT_DISPLAY_NAME} ({tenantId}). This is the same install PPAC's Install app button performs — the agent calls the BAP API directly so no manual click-through is needed. Takes ~2–5 minutes. Proceed? 1. Yes / 2. Cancel"
Call the helper:
node "${PLUGIN_ROOT}/scripts/lib/install-pipelines-app.js" \
--bapToken "{BAP_TOKEN}" \
--envId "{envId}" \
--instanceApiUrl "{instanceApiUrl}" \
--hostToken "{HOST_TOKEN}" \
--correlationId "{uuid}"
HOST_TOKEN is acquired against the chosen env's origin (az account get-access-token --resource "{instanceApiUrl origin}") and passed through so the helper's post-install verification probe (solutions?$filter=uniquename eq 'msdyn_AppDeploymentAnchor') can run end-to-end without the skill having to chain a separate verification step.
Response handling (delegated to the helper, but routing decisions live here):
{ status: 'Succeeded', alreadyInstalled: true, installPath: 'cached' } — the package was already installed on this env (idempotent path; rare in 4.B since Phase 2.5 should have classified the env as a host already, but defensive). Set ACTION_TAKEN per the dev-env-match rule above and proceed to Phase 5.{ status: 'Succeeded', alreadyInstalled: false, installPath: 'bap' } — the BAP applicationPackages/install POST succeeded (200 sync or 202 + Location poll). Set ACTION_TAKEN per the dev-env-match rule above and proceed to Phase 5.{ status: 'Succeeded', alreadyInstalled: false, installPath: 'pac', pacFallbackReason: '...' } — BAP returned 401/403/5xx (typically token-audience mismatch in tenants where Az → BAP is rejected, same scenario pac-bap-shim.js covers for env enumeration); the helper fell through to pac application install. Same outcome, log the fallback reason in docs/alm/last-host-check.json telemetry. Proceed to Phase 5.- Helper throws — both BAP and PAC failed. Surface the combined error message to the user. Last-resort fallback (manual): print the PPAC URL
https://admin.powerplatform.microsoft.com/manage/environments/{envId}/dynamics365apps and the four manual steps (Install app → Power Platform Pipelines → Next → accept terms → Install) with a follow-up "Done — proceed" AskUserQuestion. After confirmation, run verify-host-readiness.js against the env URL and proceed to Phase 5 only when the Pipelines solution is detected. This branch should be rare; if it fires often, file an issue with the helper's combined error so we can tune the BAP/PAC paths.
On success: capture the helper's pipelinesSolutionVersion (populated when instanceApiUrl + hostToken were passed). Set RESOLUTION.finalHostEnvUrl/Id. Proceed to Phase 5.
4.C — Guided manual: PPAC New custom host
🚦 Gate (progress · ensure-pipelines-host:4.C.ppac-done): External-system wait gate — user must complete the PPAC "New custom host" flow manually, then return to confirm. Skill polls BAP afterward for the new env.
Trigger: Phase 4.C entry; PPAC URL printed.
Why we ask: Skill proceeds without confirming the new env exists; downstream setup-pipeline then fails with no host. Worse, if PPAC creation succeeded partway and the user cancelled the gate, the host binding is partially established (a D365_ProjectHost-templated env exists in tenant).
Cancel leaves: host-binding — a manually-created env may be left in tenant; user must clean up via PPAC.
-
Print: https://admin.powerplatform.microsoft.com/deployments and instructions: "Click 'New custom host' → fill name (suggested: '{tenant} Pipelines Host') → choose Production environment in tenant home region → Create. Provisioning takes 5–10 min."
Per eng.ms doc: "the panel will default to the Production environment type. Adding Dataverse is also required... template and sample apps options are hidden here, as we use a specific organization template for this scenario." (The template is D365_ProjectHost — same one Path 4.A automates.)
-
Two-option AskUserQuestion: "Done — provisioning kicked off" / "Cancel".
-
After confirmation, poll BAP list-tenant-envs.js every 15s looking for a new env with the Pipelines marker. On detection, capture URLs, actionTaken = "user-created-custom-ppac". Proceed to Phase 5.
Common: Timeout handling
15-min default per path (configurable). On timeout: ask user to extend (another 15min), switch path, or exit.
Phase 5 — JIT-provision (PE-detected only) and verify host
Always runs, regardless of how finalHostEnvUrl was obtained.
JIT step (only when an existing PE was detected and selected — RESOLUTION.isPlatform === true): Per Constraint 2, the calling user may have been JIT-provisioned in the PE long ago, or never. To ensure auth works on the host before we hand off, we issue one WhoAmI against instanceApiUrl. (The same step is required for Custom Host paths but is naturally satisfied by verify-host-readiness.js step 1 below — admin who created the env has access by construction; for user-installed-app the user already had access to the env.)
GET {instanceApiUrl}/api/data/v9.0/WhoAmI
Authorization: Bearer {HOST_TOKEN}
Where HOST_TOKEN = az account get-access-token --resource "{instanceApiUrl origin}".
Expected: 200 with UserId. If 404 / 403 on first call: retry every 5s up to 60s — JIT propagation is sometimes async.
Verification (verify-host-readiness.js) — checks in order:
WhoAmI returns UserId (proves auth — and triggers JIT for PE detection case).GET {hostEnvUrl}/api/data/v9.0/solutions?$filter=uniquename eq 'msdyn_AppDeploymentAnchor'&$select=version&$top=1 returns one row → capture PIPELINES_SOLUTION_VERSION. (One query covers both Pipelines-installed check AND version capture; deploymentpipelines?$top=0 rejected by Dataverse with 400.)
Compare against MIN_PIPELINES_VERSION (constant in scripts/lib/alm-thresholds.js).
- All checks pass →
READY = true.
- Solution version below minimum → emit a warning (non-fatal).
- Any check fails → stop with check-specific remediation.
Phase 6 — Write host-check artifact
Write docs/alm/last-host-check.json (create the docs/alm/ directory first if missing — node -e "require('fs').mkdirSync('docs/alm',{recursive:true})"; or use --outputPath when invoked outside a project):
{
"schemaVersion": 2,
"checkedAt": "2026-04-28T...",
"tenantId": "...",
"sourceEnvUrl": "{devEnvUrl}",
"sourceEnvId": "...",
"resolutionStatus": "AvailableUsingPlatformHost" | "AvailableUsingCustomHost" | "AvailableUsingCustomHostByAdminDefault" | "AvailableUnboundCustomHost" | "MultipleUnboundCustomHosts" | "PlatformHostExistsUnbound" | "CannotRedirect" | "NoHost" | "OrgSettingStale" | "PermissionDenied" | "HostWithoutPipelines",
"finalHostEnvUrl": "...",
"finalHostEnvId": "...",
"finalHostInstanceApiUrl": "...",
"isPlatformHost": true | false,
| | | | | | |
|
telemetry.platformHostAlreadyExisted — only present when actionTaken === "fast-path-platform-getorcreate". true when the BAP getOrCreate returned 200 + Succeeded (idempotent — tenant already had a PE); false when the call returned 202 and we polled to completion. Lets us measure how often Phase 2.5 enumeration misses an existing PE so we can tune --maxEnvsToProbe defaults.
Schema version bump (1 → 2): added candidates.* block to record the tenant-wide enumeration result. Cache fast-path (Phase 1 step 0) reads finalHostEnvUrl regardless of schemaVersion; the candidates block is informational and helps debug / re-run decisions. Old v1 files remain readable — any missing field is treated as "not yet enumerated".
actionTaken enum — value definitions:
"none" — host already established before this run; no install/provision performed (Phase 3.A path or cache fast-path)."reuse-existing-custom" — user picked an unbound Custom Host that already existed in the tenant (Phase 3.C-pre or 3.C-pre')."reuse-existing-pe" — user picked the existing Platform Host (Phase 3.C-pre'')."fast-path-platform-getorcreate" — Phase 4.0 invoked the BAP getOrCreate endpoint. The telemetry.platformHostAlreadyExisted flag distinguishes idempotent-existing (200) vs. newly-provisioned (202) outcomes."fast-path-custom-d365projecthost" — Phase 4.A provisioned a new Custom Host via the env-create API."user-installed-app" — Phase 4.B installed Pipelines on an existing env that is not the same as the dev env."user-installed-app-on-dev" — Phase 4.B installed Pipelines on the dev env itself (URL origin matches devEnvUrl). Telemetry-distinct from "user-installed-app" so we can see how often users co-locate Pipelines with their dev env."user-created-custom-ppac" — Phase 4.C — user created the env via the PPAC UI; flow detected it post-create.

Follow the skill tracking instructions in the reference to record this skill's usage. Use --skillName "EnsurePipelinesHost".
Refresh the ALM plan (if one exists):
node "${PLUGIN_ROOT}/scripts/lib/refresh-alm-plan-data.js" \
--projectRoot "." \
--phase ensure-pipelines-host \
--render
This updates planData.hostResolution from the docs/alm/last-host-check.json you just wrote (host-only — no pipeline yet) and drops the pre-run NoHost risks, then re-renders docs/alm-plan.html. Do this here, not just in setup-pipeline Phase 7 — a host install can take 18+ minutes and cross a session boundary, so deferring the refresh risks the plan never reflecting the host. When docs/.alm-plan-data.json is absent (standalone, not part of an ALM plan), the helper returns ok:false as a soft no-op. The centralized PostToolUse hook also reconciles the plan as a backstop, but refreshing at the source keeps the rendered plan current immediately.

Integration with existing skills
setup-pipeline (✅ wired)
setup-pipeline/SKILL.md Phase 1 step 4 calls ensure-pipelines-host-detect.js (the orchestrator wrapper) and branches on resolutionStatus:
AvailableUsing* → use finalHostEnvUrl directly, continue.*Unbound* / NoHost → delegate to /power-pages:ensure-pipelines-host (this skill) for reuse-or-provision; resume after docs/alm/last-host-check.json shows ready: true.CannotRedirect / OrgSettingStale / PermissionDenied → stop with the specific admin-resolution message.
The old "ask user for host URL manually" fallback in Phase 3 has been removed — HOST_ENV_URL is always populated by Phase 1, or the skill stops before Phase 3.
deploy-pipeline
No change. deploy-pipeline reads hostEnvUrl from docs/alm/last-pipeline.json written by setup-pipeline.
plan-alm (✅ wired)
plan-alm Phase 1 step 12 invokes ensure-pipelines-host-detect.js and stores the result as HOST_RESOLUTION (skipped when PIPELINE_DONE = true). Phase 2 Q4 branches on HOST_RESOLUTION.status. The generated docs/alm-plan.html includes a "Pipelines Host" card and (when willEnsureDuringExecution: true) a sub-bullet under the "Setup pipeline" checklist step. See references/cicd-pipeline-patterns.md and the plan-alm-update-PLAN.md spec.
Threat model — built-in mitigations
| Risk | Mitigation in this skill |
|---|
| Confused-deputy / silent provisioning | Phase 1.4 tenant identity gate + Phase 3 explicit choice + Phase 4.A pre-call confirmation echoing the exact request body |
| Duplicate host creation | Phase 2.5 tenant-wide enumeration finds any existing Custom Host before Phase 3 offers to create. Phase 3.C-pre / 3.C-pre' surface existing hosts for reuse. User must explicitly decline reuse (option "No") to reach the create-new tree. |
| Stale local cache → using a deleted host | Phase 1.0 cache fast-path validates with a live solutions?$filter=uniquename eq 'msdyn_AppDeploymentAnchor'&$top=1 probe before reusing — 404/403/timeout falls through to full Phase 2 |
| 404 ambiguity → unintended action | Phase 2.2 disambiguation rule — never act on a single 404; corroborate with list-tenant-envs |
| Wrong-tenant provisioning | Phase 1.4 echoes tenantId, organizationId, and dev env URL; Phase 4.A echoes tenantId in the pre-call body |
CannotRedirect masked | Phase 2.3 explicitly detects this and stops with a specific error rather than continuing into a wrong-host write |
| JIT-provisioning miss → silent 404 chains | Phase 5 makes WhoAmI call against instanceApiUrl before any other host op (relevant when an existing PE was detected) |
| Stale solution → silent failure | Phase 5 reads PIPELINES_SOLUTION_VERSION and warns if below MIN_PIPELINES_VERSION |
| Non-admin tries Custom Host fast-path | Phase 4.A pre-prompts for admin role; gracefully falls back to Phase 4.B / 4.C on 403 |
| Tenant-singleton PE created accidentally | Phase 1.4 tenant-identity gate (echoes tenant display name + tenant ID + dev env URL) + Phase 4.0 pre-call confirmation gate (echoes tenant display name + tenant ID again, immediately before the call). The getOrCreate endpoint is idempotent — calling it on a tenant that already has a PE returns the existing one (200 + alreadyExisted = true) rather than creating a duplicate. |
| Telemetry leakage | All probe results stay in docs/alm/last-host-check.json; correlation ID is the standard x-ms-correlation-id UUID we generated; update-skill-tracking.js writes only counters + authoring-tool name |
| Privilege boundary |
Key decision points (wait for user)
- Phase 1.4 — Tenant identity confirmation (read-only intent)
- Phase 3.A/B/C-pre/C-pre'/C-pre''/C/D/E — Branch decision based on
RESOLUTION.status
- Phase 3.C-pre — Reuse single existing Custom Host (Y/N/Cancel)
- Phase 3.C-pre' — Pick from multiple existing Custom Hosts or create new
- Phase 3.C-pre'' — Use existing PE or create Custom Host instead
- Phase 3.C — Create-new path selection (4 options: Custom-fast, app-install, PPAC-UI, cancel)
- Phase 4.A — Admin-role self-attestation (No / Not sure → fall back to 4.B / 4.C)
- Phase 4.A — Pre-call confirmation echoing exact API request body
- Phase 4.B/C — User performs UI step → confirms back via "Done — proceed"
- Phase 5 — Warning acknowledgement if Pipelines solution version is below minimum
Error handling
verify-alm-prerequisites.js fails → stop with remediation (az login, pac auth create)- BAP token acquisition fails → stop; suggest
az logout && az login
- BAP env GET returns 404 → run disambiguation (Phase 2.2 fallback)
- BAP env GET returns 403 →
RESOLUTION.status = "PermissionDenied", surface tenant ID + env ID, stop
- Custom Host env-create returns 403 → seamless fallback to 4.B (app install) or 4.C (PPAC UI)
- Custom Host env-create returns 4xx other → log status + body, ask user to retry or switch path
- Lifecycle-op polling timeout (15 min default) → ask: extend (another 15min) / switch path / exit
RetrieveSetting returns 404 → treated as "no admin default custom host" (current discover-pipelines-host.js behavior)GetOrgDbOrgSetting returns 404 → treated as "not bound" (matches UI behavior)- WhoAmI on host returns 403 after JIT retries → likely
CannotRedirect race or genuine perm issue; stop with both error message
verify-host-readiness.js reports Pipelines tables not found after user-claimed install (4.C) → ask user to recheck PPAC or extend polling

Open items (resolve during execution phase)
These need real-environment validation:
Pipelines solution uniquename. ✅ RESOLVED 2026-04-28: confirmed msdyn_AppDeploymentAnchor v9.1.2026034.260325188 via live query against SIP host (pascalepipelineshost.crm.dynamics.com). Stored as PIPELINES_SOLUTION_UNIQUE_NAME constant.MIN_PIPELINES_VERSION. Set after testing which Pipelines features fail on the lowest in-the-wild solution version. Initial conservative guess: "9.0.0.0".Custom Host detection marker in list-tenant-envs.js. ✅ RESOLVED 2026-04-28: confirmed via live BAP env-list query (1000 envs in test tenant) — linkedEnvironmentMetadata.templates is never returned even with $expand=properties.linkedEnvironmentMetadata. Per-env Dataverse probe is mandatory. Probe query corrected to solutions?$filter=uniquename eq 'msdyn_AppDeploymentAnchor'&$select=version&$top=1 (covers presence + version in one call). PE detection still straightforward via environmentSku === 'Platform'.BapApiVersion value for env-create. The D365_ProjectHost template was onboarded for Pegasus / BAP-RP / Neptune (per eng.ms PR list). The PPAC UI uses 2021-04-01 for env operations. Confirm during execution by capturing a fresh HAR from New custom host.- Lifecycle-op response shape. Need to confirm whether the Location URL returns
{ properties: { provisioningState } } or { state } or both. To be HAR'd.
- Tenant home geo discovery. Default region for 4.A. Options:
BAP_TOKEN claims (tid, xms_tcdt?), BAP /tenant?api-version=2021-04-01 endpoint, or properties.azureRegionHint from existing envs. Pick one during execution.
- Cold-tenant test env. Need a tenant with no prior Pipelines usage to validate end-to-end. A personal MSDN tenant works.
- BAP env-list filter on
linkedEnvironmentMetadata.templates? If supported, we can pre-filter to envs created with D365_ProjectHost and skip the per-env Dataverse probe in Phase 2.5b. To be tested. If unsupported, the per-env probe with bounded concurrency stands.
