(Preview) Builds and edits a model-driven Power Apps app from a natural-language intent — tables, columns, relationships, adaptive forms with sub-grids, views, Choice-column charts, generative page intents for overview/dashboard surfaces (page `.tsx` generated in generate-pages after plan approval), and an app module + sitemap — via the headless cds-maker-sdk. Runs an interactive, multi-turn authoring flow (env selection, jobs-to-be-done first, then design-only App Spec authoring across confirmed levels, guardrail lint, plan-mode approval, generate-pages, full build) and a narrated build, and can download a deployed app back into an editable spec to change it. Use when the user says "build an app for X", "create a model-driven app", "make me an app to manage Y", or "edit/add to my app". This skill stands alone and does not require /genpage — but for a standalone generative page added to an app that already exists, use /genpage instead.
Plugin check: Run node "${PLUGIN_ROOT}/scripts/check-version.js" — if it outputs a message, show it to the user before proceeding.
app-builder — intent → model-driven app
⚠️ Preview. This skill is in preview — its App Spec shape, flags, and build behavior may change
between versions. Review the plan-mode summary before applying, and prefer a non-production
environment while it stabilizes.
Turn a natural-language intent into a deployed model-driven app. You author a reviewable App Spec
(JSON) with the user across confirmed turns, then a deterministic engine (cds-maker-sdk, vendored)
builds it — tables/columns/relationships, sample data, views, Choice-column charts, adaptive forms
with sub-grids, generative pages for overview/dashboard surfaces, and the app module + sitemap.
The same spec drives create and edit: download a deployed app back into a spec, change it, and
re-run the build (it's idempotent).
CRITICAL — run the interactive flow in THIS conversation (the main loop)
You MUST run the authoring questions and the build narration yourself, in the main
conversation. Do NOT dispatch a subagent (Task) for the interactive steps.
A subagent is headless — AskUserQuestion and plan mode do not reach the user from inside one
(its only output is its final message). The whole point of this skill is the multi-turn,
propose-then-confirm experience, so every AskUserQuestion, EnterPlanMode, and live build
status line must originate here, in the main loop.
CRITICAL — the user sees your chat message, NOT tool output
Shell/tool output — the result of running preview-app.js, a dry-run plan, or a lint —
is COLLAPSED BY DEFAULT in the UI. The user does NOT see it unless they manually expand the
tool panel. Running the command is therefore NOT the same as showing the user. Every artifact
the user must read, review, or approve — the whole-app preview wireframes, the
dry-run build plan, and blocking lint findings — MUST be reproduced verbatim in your
chat reply, inside a fenced ``` code block. Never say "the preview looks right" and leave
the content buried in a collapsed panel: paste it into your message. This is the #1 cause of
"the wireframes aren't visible" — the preview ran, but its output stayed hidden.
Capabilities — the full toolbox (pick best-fit per requirement)
You are a complete model-driven app builder, not a single-surface tool. Everything below ships in
one App Spec and one build — choose what best serves the user's requirement to make a useful,
prod-ready app; don't under-build (a bare table list) or over-build (surfaces nobody asked for):
Data model — tables (give each custom table a meaningful Fluent-style SVG table icon by default; propose what the glyph will depict in words — never a Fluent token name — and record it as iconDescription before drawing the SVG — see references/authoring-flow.md → Table icons), columns (all types), relationships (1:N / N:N + junctions), sample data
Record UI — forms (sub-grids, quick-create / quick-view), views (with enriched default columns), charts
Actions — modern command-bar buttons (incl. flyout / split menus), web resources (form JS / HTML / CSS)
App shell — the app module + sitemap, with per-subarea icons
Security & access — one security role per persona, sized from that persona's jobs-to-be-done
(the entity access each job needs, unioned into the role), so the app opens for non-admins.
AI-first features (admin-gated) — form-fill assist, natural-language grid/view search, NL chart
/ AI data visualization, M365 Copilot (opt-in); per-table Copilot row summaries (Insight Cards)
with tailored prompts, auto-selected for good-candidate tables
Author the smallest spec that fully satisfies the ask, then let the user refine. The Genpage-first
policy below is the record-vs-dashboard rule; references/app-spec-schema.md
documents every field.
Genpage-first policy (surface classification)
Every app surface is one of two kinds — enumerate the app's surfaces and classify each one, don't
decide page-by-page in passing:
Record surfaces (create/read/update/list a table's rows) → a model-driven form + view.
Everything else — overview/landing, dashboard, KPIs, analytics, guided or wizard flow,
composite or comparison screen → a generative page (pages[]), not a classic dashboard.
Rules:
An app whose jobs include an overview, a queue, analytics or a guided flow but which proposes no
pages has missed a surface. Where the app genuinely is record-CRUD only, say so explicitly rather
than silently omitting pages.
A traditional dashboards[] is emitted only on explicit request (e.g. "use a classic dashboard").
A generative page is authored as a design intent (source: { kind: "intent" },
schemaVersion: 2) during Phase 1 — its .tsx is written in Phase 1.5 — Generate pages, after
plan approval and after the data pre-build creates the tables so pac model genpage generate-types
can emit RuntimeTypes.ts. See references/authoring-flow.md → Pages.
The build's pages phase uploads each page via pac model genpage uploadwithout
--add-to-sitemap — the SDK is the single sitemap writer, so a page's nav entry comes from a
page subarea in appShell (referenced by the page's key). See
references/app-spec-schema.md → pages[].
Every page in pages[] must be sitemap-placed — validation rejects any page absent from the
sitemap. A "detail" page that receives a caller-supplied id is a normal sitemap page; it reads its
input via pageInput?.data?.<field>. Navigation-only (headless) pages are not supported.
Three-authority page identity (build + download + verify all follow this): (1) IDENTITY —
the durable <app>_pagemanifest (key → pageId); a downloaded spec's own pages[].pageId
outranks it for that rebuild. (2) EXISTENCE — env-wide pac model genpage list (crash-safe;
decides create-vs-reuse). (3) MEMBERSHIP — the app's sitemap GenPageId set (placement,
download enumeration, verify coverage). All matching is by id — never by display name.
Multi-page navigation uses PAGEREF_<key> (the stable pages[].key) as the pageId
placeholder; the build resolves each to the real page GUID in a run-scoped staging copy (the
canonical .tsx is never mutated), then verifies every nav edge resolves to the deployed
page's GenPageId.
Workflow
Phase 0 — Working directory
Derive a short kebab-case slug from $ARGUMENTS (e.g. "Project Tracker" → project-tracker).
Create the directory (mkdir -p <slug> on bash/PowerShell; mkdir <slug> on cmd, which has no
-p and errors if it exists) and resolve its absolute path. It holds app-spec.json,
model-app-plan.md, and workflow-log.md.
Phase 1 — Author the App Spec (interactive, main loop)
Environment (PAC) — pac auth list. If exactly one / an active profile, confirm it
(FYI), don't ask. If several and none active, ask which to use. If none, ask the user
to pac auth create. Capture the org URL (pac org who).
Detect existing — pac model list-tables --search … (exact-match) and pac model list
to find tables/apps already present; build around them.
Levelled authoring — first read the App Spec format so you author to the exact
shape (do this once; don't go spelunking through scripts):
references/app-spec-schema.md and the worked sample
samples/app-spec.support-desk.json. Phase 1 is
design-only: never emit page .tsx here. Each level is confirmed via AskUserQuestion before
the next begins, and app-spec.json is persisted after each — full prompts in the playbook.
Level (a0) — personas & jobs-to-be-done (personas[]): before proposing any tables, ask
who will use the app and what each needs to get done. Jobs drive everything that follows — a
table exists because a job needs its data, a surface because a job needs to act on it. Deriving
the data model first reliably misses surfaces. Privileges come later; capture the jobs now.
Level (a) — data model: entities/columns/relationships derived from those jobs; run the
early data-model lint (catches e.g. the relationship-vs-lookup collision before forms are
authored on top).
Level (b) — artifacts + page-intents + design: enumerate every surface each job needs and
classify it per the genpage-first policy above — record CRUD → form + view; anything else
(overview/landing, dashboard, KPIs, analytics, guided/wizard flow, composite or comparison
screen) → a page intent (source: { kind: "intent" }). State each classification out loud;
if the app needs no pages, say so and why rather than silently omitting them. Then forms + views
charts + sample data and the optional design contract, mapping each job to its surfaces via
jobs[].surfaces[]. No page .tsx here.dashboards[] only on explicit request.
Level (c) — access (personas[].jobs[].privileges[]): personas and jobs already exist from
(a0) and the entities now exist, so only add the privileges each job needs — don't re-ask who
the users are. The builder unions them into one role per persona and grants the app to it so it
opens for that persona, not just sysadmins. Render the roles + per-entity access as a table
in your chat reply (the user can't approve an access model they can't see — see the CRITICAL
note above). If they want no roles, tell them jobs live in personas[] so dropping the roles
drops the recorded jobs too; offer read-only privileges to keep the record. (Column-level
security and access teams are not yet supported — see Notes & limits.)
Whole-app preview (design gate for Level (b)): node "${PLUGIN_ROOT}/scripts/preview-app.js" --spec @<working-dir>/app-spec.json
renders data-model + sitemap + form wireframes + page-intents + design contract. Reproduce the
ENTIRE rendered output verbatim in your chat reply, inside a fenced ``` code block — do NOT
leave it in the (collapsed, invisible) tool output, and do NOT just summarize "the preview looks
right" (see the CRITICAL note above). The user must be able to SEE each form, the sitemap, and
the page intents they are approving. For a single form only: node "${PLUGIN_ROOT}/scripts/preview-form.js" --spec @<working-dir>/app-spec.json.
Don't pre-create tables/columns — the build does it idempotently.
Guardrail lint (hard gate) — run the fullspec-lint.js on the complete spec; errors block, warnings teach. If it blocks (or warns), paste the findings into your chat reply — tool output is collapsed and invisible to the user (see the CRITICAL note above), so the user can't fix what they can't see:
Plan-mode approval (the single build approval) — present the plan including the build
dry-run's phase-grouped plan (run build-model-app.js without --apply, using the plan
profile that allows intent pages) inside EnterPlanMode, then ExitPlanMode to get the user's
go-ahead. On approval, Phase 1.5 (generate-pages) runs first, then Phase 2 applies
directly (no second dry-run/go-ahead). Render the design document — never hand-write it:
It writes <working-dir>/model-app-plan.md (jobs → surfaces traceability, data model, every
surface, navigation, access model, sample data) and prints { ok, docPath, bytes, warnings }.
Surface those warnings — they name design gaps such as a job with no covering surface or an
app with no generative pages. Tell the user where the document is; it's theirs to keep, and it's
regenerable after any spec edit.
Data pre-build — schema-only build so generate-types can resolve real column names:
node "${PLUGIN_ROOT}/scripts/build-model-app.js" \
--env <envUrl> --spec @<working-dir>/app-spec.json --stage data --apply
--stage data applies solution + data-model only — no --sample-data (rows are created
once in the full build). Only --stage data is apply-safe; all other --stage selectors
and legacy --from/--to/--only/--skip selectors are dry-run inspection only.
Types — generate Dataverse type bindings for the entities the pages read:
pac model genpage generate-types --data-sources "<entity1,entity2,…>" --output-file <working-dir>/RuntimeTypes.ts
--data-sources is the union of every intent page's dataSources. Skip this step entirely when
every intent page is mock-only. On Windows use forward slashes in the path.
Page plan (adapter) — the page worker's input contract is a plan document, not an App Spec,
so project the spec into one. This also echoes the per-page dispatch parameters:
node "${PLUGIN_ROOT}/scripts/write-page-plan.js" \
--spec @<working-dir>/app-spec.json --working-dir <working-dir> --env <envUrl> \
--app "<app name>" --languages "<languages from the environment probe>"
It writes <working-dir>/app-builder-page-plan.md and prints
{ ok, planPath, pages: [{ name, key, file, dataMode, intent }] }. Pass --languages through
from the environment probe — omitting it silently defaults every plan to English-only and drops
the localization pattern. The command fails (before writing) if the plan would name a sample that
doesn't exist.
Generate — for each page from step 3 with intent: true, dispatch the headlessgenpage-page-builder worker via Task. Use its documented input contract verbatim — a missing
field is why a page silently never becomes .tsx:
You are the genpage-page-builder agent. Generate the [name from step 3] page.
Target file: [file from step 3 — already includes .tsx; do NOT append another]
Plan document: [absolute path to the app-builder-page-plan.md written in step 3]
Data mode: [dataMode from step 3 — dataverse or mock]
Connectors: disabled
RuntimeTypes: [absolute path to RuntimeTypes.ts] ← omit this line when Data mode is mock
Working directory: [absolute working-dir path]
Plugin root: ${PLUGIN_ROOT}
Follow the instructions in your agent file. Write [file] and return your result when done.
The plan's ## Environment carries Mode: app-builder and every page row carries a Key, so
the worker emits "PAGEREF_<key>" for cross-page navigation (never a file-derived token — a
downloaded page's codeFile is a path, not its identity). Custom nav ids go in data: — never
recordId. Connectors: disabled is a constant here: the App Spec has no connector-binding
concept, so the projected plan always says No connector bindings.
Validate + commit the transition (transactional) — never flip source by hand, and never
flip pages one at a time as workers return. Run:
It checks every generated page (file written, structurally a module, PAGEREF_ tokens
canonical and in exact parity with the spec's navigatesTo edges) and only then flips all
of them intent → { kind: "tsx", codeFile } in a single atomic write. On any failure it
exits 3 and leaves app-spec.json untouched, printing which page failed and why —
regenerate just those pages and re-run. All-or-nothing on purpose: a half-flipped spec would
claim a .tsx that was never written, and Phase 2's deploy profile fails fast on any
remaining source.kind === "intent".
Proceed to Phase 2 (full idempotent build).
⚠️ The interactive author never runs inside a Task subagent. Only pure, headless
code-gen workers are dispatched here — all user-facing prompts originate in the main loop.
Phase 2 — Build (narrated, main loop)
Always use scripts/build-model-app.js. Never hand-write a builder. It's idempotent
(skips existing solution/tables/columns/relationships — so new, existing, and mixed envs all
just work), so you don't pre-create anything or special-case existing tables.
The build plan was already presented and approved in plan mode (Phase 1 Step 6 shows the engine's
real dry-run plan), so on approval apply directly — one build approval, no second go-ahead. Add
--verify so the build self-checks after applying (see Phase 3):
Each step streams its status live ([n/total] ✓ created / ⊘ skipped / ✗ failed — <error>) and a
closing ✓ build complete — X created, Y skipped, Z failed summary.
Keep the build's progress visible. A full build runs for several minutes. Let its output
stream — do NOT pipe it through Select-Object -First/-Last N or Select-String head-limits,
which buffer and hide progress until the run ends (and can truncate a still-running pipe). To
capture the log use Tee-Object -FilePath <log> (no head-limit). The build also prints a
▸ live progress: line pointing at <workspace>/.maker-workspace/build-status.json — a snapshot
(state, steps, lastPhase, lastLabel) overwritten every step. Read it (or tail
build-log.jsonl) any time to report where a long build is, even if stdout is buffered.
(Reaching Phase 2 without a fresh plan-mode approval — resuming a failed build, or a quick edit
re-run — do a dry-run first (drop --apply), paste the phase-grouped plan verbatim into your
chat reply (tool output is collapsed — see the CRITICAL note above), and get a go-ahead
before applying.)
Stage selector (--stage <data|ui|app|publish>) maps to its phase range. On --apply, ONLY
--stage data is accepted (solution + data-model, no rows in run 1; run 2 is a full build). All
other stages and the legacy --from/--to/--only/--skip selectors are dry-run inspection only —
their phase ranges are not dependency-closed and are rejected on --apply.
Narrate progress as it runs. Transient env errors (429 customization-lock, 503 SQL-timeout,
concurrent-op guards) are auto-retried with backoff on --apply (the build is idempotent, so a
retry reuses what's already created). If the build still halts (BuildHalt) on an
unrecoverable error, surface it and ask the user how to proceed via AskUserQuestion (adjust the
spec / cancel), then re-run. Everything is scoped to a dedicated unmanaged solution; --publish
gates the final bulk publish — edit/finalize paths still publish their one targeted artifact so the
change takes effect (see Notes & limits).
Recovery from a failed or halted build: run the full build again. The build is idempotent — every
phase re-uses what's already created and only fills the gaps. SDK metadata is persisted under
<working-dir>/.maker-workspace/ (override with --workspace). There is no apply-safe
--from <phase> shortcut; a full rerun is the correct and safe recovery path.
Phase 3 — Verify & iterate
--apply --verify already reconciled the spec against what deployed (Phase 2) — the build appends a
verify PASS / verify FAIL — N missing line and exits non-zero on a silent partial (an artifact
created but not wired, or a phase that quietly produced nothing). To re-check later — e.g. after a
Maker change, without rebuilding — run the standalone read-only verifier (entities/columns/views/charts/
forms and sitemap subareas + icons; exits non-zero and lists anything missing):
Then open the app in the browser. Refine app-spec.json and re-run Phase 2 to iterate.
Teardown (cleanup). To remove everything an App Spec built — e.g. a live-verification probe or a
failed build — run the classifier-safe teardown. It deletes only the artifacts the spec declares, in
dependency order (app module → security roles → dashboards → command bars → forms → charts → views
→ reset enriched default views to drop parent lookups → relationships → AI row summaries → tables
[children-first] → web resources (generated app icon + page manifest + declared) → global choices →
solution). Forms/charts/views/relationships are deleted explicitly before tables (a table
delete does not reliably cascade cross-references; it does remove the table's own columns). Command
teardown removes the whole command bar for any entity the spec authored commands on. Teardown only
deletes tables this build created — a system/standard table (account, contact, …) is
auto-detected and skipped, and a reused custom table is skipped when its entity is flagged
"existing": true, so pre-existing data survives. Dry-run by default; add --apply --allow-destructive to actually delete (--clear-workspace also prunes .maker-workspace/).
--allow-destructive is required for teardown --apply — without it teardown refuses and
touches nothing.
Safety flags (build + teardown). The apply path is fail-closed against destructive operations:
--allow-destructive — authorize destructive operations. For build --apply: authorizes
overwriting an existing app in unattended mode, and allows explicit-layout form-field removals or
sitemap-target drops; also authorizes DETACHING a pages-removed page's nav subarea (the page
record is left deployed — it is not deleted). For teardown --apply: required — all deletes
are destructive by construction, so teardown without this flag halts before touching anything.
Pages-phase safety HALTs. The build halts on identity or safety violations rather than
proceeding with potentially wrong state. Surface the HALT reason and follow the recovery hint:
pages-identity-conflict — spec pageId and manifest disagree on a key, or a duplicate id
spans two keys. Resolve the conflict manually (re-download or delete the manifest).
pages-manifest-corrupt — the manifest cannot be parsed (two keys map to the same id). Delete
the manifest web resource and rebuild from scratch.
pages-removed — a live page was dropped from the spec. Re-add it, or pass --allow-destructive
to detach it from the nav (the page record stays deployed; rebuild finalizes the sitemap).
pages-shared-across-apps — the page appears in another app's sitemap. Detach it in Maker.
--allow-destructive does not bypass this halt.
pages-shared-check-failed / pages-existence-failed / pages-sitemap-read-failed — a
prerequisite read failed; the build can't proceed safely. Retry on a transient error; check
permissions on a persistent one.
--non-interactive — suppress interactive prompts (for automation / CI). A non-interactive
build that encounters an existing app fails instead of warning-and-proceeding, unless
--allow-destructive is also set. Does not grant destructive authority on its own — only
--allow-destructive does.
POWER_PLATFORM_SKILLS_NONINTERACTIVE=1 (or true) — env-var equivalent of
--non-interactive. Same semantics: suppresses prompts only, never authorizes destructive ops.
Set this in CI job environments to avoid interactive-prompt hangs.
In autopilot / eval mode (--non-interactive + --allow-destructive), preview-app.js
is written to disk as the design artifact before plan execution; interactive consent gates are
bypassed and the build is fail-closed against any destructive op not explicitly authorized.
AI-first features
The ai block in the App Spec controls four app-level features and per-table Copilot row
summaries. All features are admin-gated: they are enabled only where the environment
administrator has turned them on in Power Platform Admin Center (Environments → Settings →
Product → Features). The ai-features build phase preflights each setting via the SDK
(RetrieveSetting) and, for anything off, skips it with a warning — it never fails the
build and cannot flip admin or tenant switches itself.
Prints each feature's on/off status and the exact admin action required for anything that is off.
Never fails.
App-level features (ai.appFeatures) — formFill (Copilot-assisted form fill), nlSearch
(natural-language grid/view search), nlChart (NL chart / AI data visualization), m365 (M365
Copilot). All default to true except m365; set any to false to opt out.
Per-table row summaries (ai.summaries):
default: "auto" — the skill auto-selects good-candidate tables (skips lookup-only / config /
junction tables and the Dynamics 365-owned incident, lead, opportunity).
default: "off" — summaries disabled unless a table opts in explicitly.
Per-table overrides in summaries.tables: set enabled, a tailored instruction, and
columns[] (the fields the summary reads). A { "enabled": false } entry opts a specific
table out.
Prompt authoring guidelines (for instruction): write for meaningful insights — not field/value
repetition; never include record GUIDs; pull in recent activity where relevant; use
audience-appropriate tone; aim for an explicit output shape (a short paragraph).
Teardown removes the AI records created by the ai-features phase (summary config rows and
published AI models) in addition to the standard artifacts.
Editing a deployed app (download → edit → rebuild)
The same App Spec drives edit — there is no separate edit path. When the user wants to change an
existing app (add a field/view/page, edit a page's code, retitle/reorder nav, swap an icon), pull the
deployed app fresh into a spec first, then edit that spec and re-run Phase 2:
--app resolves in identity order: app id (GUID) → uniquename → display name. Prefer the unique
name — it is immutable, while a display name can be renamed and is not unique. A display name that
matches more than one app is refused, listing the candidate unique names rather than guessing.
This reconstructs the app into <working-dir>/app-spec.json. Round-trip scope — be precise, it is
not everything:
Round-trips: the sitemap → appShell (all subareas + icons), every generative page (via
pac model genpage download; names come from the sitemap's GenPage subarea titles, so
Maker-added pages are included) into pages[] + their .tsx, the referenced entities (minimal —
the build reuses existing tables), classic dashboards (id-passthrough tiles carrying the
deployed view/chart ids), the icon web resources, and the solution.
Does NOT round-trip:forms[], views[], charts[], commands[] — they come back empty.
All four survive on the live app (a rebuild preserves them by discovery), so a plain edit is
safe; they just aren't editable through the downloaded spec. Change them in Maker or a fresh spec.
Then:
Always pull fresh at the start of an edit session — someone may have changed the app in Maker. The
build reads an etag when it hydrates, so a write against an artifact changed since the pull throws a
version conflict → re-pull and retry, never clobber.
Edit app-spec.json (and any page .tsx) for the requested change.
If the edit ADDS a page (or resets a page's source back to intent to regenerate it),
re-run Phase 1.5 before Phase 2 — a downloaded spec contains only kind: "tsx" pages, so an
added intent page has no code and Phase 2's deploy profile rejects it. Phase 1.5 is safe to
re-run: write-page-plan.js projects all pages (so the worker sees the real nav graph), a
worker is dispatched only where the echo says intent: true, and promote-intent-pages.js
leaves built pages untouched. Editing an existing page's .tsx by hand needs no regeneration.
Re-run the build (Phase 2). It's idempotent: it reuses the existing app/tables/views, updates
each page in place (matched by name → --page-id, so no duplicates), and preserves the
existing GenPage subareas (the download enumerated them into pages[]/appShell, so the
full-replace sitemap write never drops them).
Verify (Phase 3) to confirm only the intended change landed.
Prefer generative pages over classic dashboards per the genpage-first policy. Classic dashboards
do round-trip (id-passthrough tiles), but the views and charts their tiles point at do not, so they
can only be edited in Maker.
What the builder does (in order)
solution (idempotent) → data model — discover existing tables/columns/relationships via the SDK
(findTables / findColumns / fetchEntityMetadata) and create only what's missing (createTable
/ createColumn / createRelationship) → sample data (opt-in; relational/topological,
$parent→@odata.bind using the entity-set name) → web resources (opt-in;
createWebResource for form JS/HTML/CSS) → views → charts → forms (primary + columns
laid out, explicit tabs honored; sub-grids, quick-views, and form JS (events[]) applied as
canonical control cells / the /bag/c events region via the SDK's generic addElement surface)
→ app module + sitemap → generative pages (each page's .tsx was generated in Phase 1.5;
the build uploads each pages[] page via pac model genpage upload, no --add-to-sitemap; then
the SDK rewrites the sitemap once to add the GenPage subareas) → AI features (opt-in) →
security (one role per personas[] entry, sized from its jobs' declared access; injects an
app-module read privilege and associates the app to each role so it opens for that persona) →
publish (opt-in). When the app has generative-page subareas the app module is created first WITHOUT
them (they can't resolve until the pages upload), then the pages phase rewrites the sitemap. All
Dataverse access goes through the SDK, so the downloaded metadata lands in .maker-workspace/.
Independent ops (columns, views/charts/forms) run with bounded parallelism; publish is one
round-trip per entity + the app. Views/charts build before forms so a sub-grid can reference the
child view id. Each step emits [n/total].
Notes & limits
Headless, no browser. The SDK (cds-maker-sdk, vendored at scripts/vendor/) generates
designer-grade FormXML/FetchXML/sitemap by reusing the designer's own serializers, and writes via
the Web API using an az-token HttpClient. No relay, no designer tab.
Dedicated unmanaged solution per app (review / teardown). --publish gates the final
bulk publish of the app's entity + app customizations (a PublishXml per entity + the app). It
does not suppress the small targeted publishes that edit/finalize paths must run so the change
takes effect — reconciling an existing form or view, wiring form events, placing quick-views,
re-syncing an existing app's sitemap, and finalizing the sitemap after generative pages each publish
that one artifact (an unpublished edit to a live artifact is invisible). A fresh build without
--publish still leaves new tables/columns/relationships staged-but-unpublished in the solution.
Idempotent — but ADDITIVE, not yet full desired-state convergence. Existing
solution/tables/columns/relationships/views/charts/forms/commands/dashboards are detected and
reused, so re-runs and existing-table envs work without collisions. The caveat for EDITS: a
rebuild is additive — it creates what's missing but does not re-apply changes to an artifact
that already exists (a changed column type, a removed view column — reconcileView only adds —
an edited form/command/dashboard), and never removes an artifact you dropped from the spec. To
apply a structural edit, teardown --apply then rebuild fresh.--verify catches this: it
checks content (a view's column set, relationship + command existence), so an unapplied edit
surfaces as a loud verify FAIL, not a false pass. Full in-place convergence is tracked in
docs/app-builder-roadmap.md.
Not in scope (later): business rules, conditional command visibility (Power-Fx-only), titled
command groups (from-scratch — needs an SDK-synthesized parent row), lookup/associated views,
multi-area sitemaps, column-level (field) security, access teams / hierarchy security (the
security surface today is role-per-persona only — a tracked SDK follow-up).
Supported: the full data model — all column types, AutoNumber primary, global choices, status
reasons, alternate keys, N:N + junction-with-payload; adaptive main forms with 1:N / N:N
sub-grids; quick-create / quick-view forms (formType) + quick-view placement
(forms[].quickViews[]); Choice-column charts; security roles (personas[] — one role per
persona sized from its jobs-to-be-done, with app access so the app opens for non-admins);
dashboards (dashboards[] — chart/list/iframe/webresource tiles) + dashboard sitemap
placement; generative pages (pages[] — the genpage-first default, uploaded via
pac model genpage upload and surfaced as GenPage sitemap subareas; full create + edit
round-trip via download-model-app.js); modern command-bar buttons (commands[]) incl.
flyout / split-button menus; rich view filters (eq-userid/this-week/in/not-in);
web resources + form JS event handlers; sample data with multi-parent $parents +
statusReason. See docs/app-builder-roadmap.md and
references/app-spec-schema.md — author from that single
doc; you should not need to read the SDK, lint, or engine to write a spec.
