Overview

This skill orchestrates four specialist agents across the create and edit flows:

Create flow:

1. genpage-planner — validates prerequisites, gathers requirements, detects what entities and apps exist, presents a plan for approval, writes genpage-plan.md
2. genpage-entity-builder — creates Dataverse entities (tables, columns, relationships, choices, sample data) via the plugin's Node.js Web API scripts
3. genpage-page-builder — generates one complete .tsx file per page; multiple builders run in parallel for multi-page requests

Edit flow:

4. genpage-edit-planner — reads the downloaded page artifacts, gathers change requirements, presents an edit plan, writes genpage-edit-plan.md

You (the skill) coordinate the agents and own app creation, RuntimeTypes generation, deployment, browser verification, and the inline application of planned edits.

Development Standards

• React 17 + TypeScript — all generated code
• Fluent UI V9 — @fluentui/react-components exclusively (DatePicker from @fluentui/react-datepicker-compat, TimePicker from @fluentui/react-timepicker-compat)
• Single file architecture — all components, utilities, styles in one .tsx file
• No external libraries — only React, Fluent UI V9, approved Fluent icons, D3.js for charts
• Type-safe DataAPI — use RuntimeTypes when Dataverse entities are involved
• Responsive design — flexbox, relative units, never 100vh/100vw
• Accessibility — WCAG AA, ARIA labels, keyboard navigation, semantic HTML
• Complete code — no placeholders, TODOs, or ellipses in final output

Instructions

Follow these phases in order for every /genpage invocation.

Phase 0: Create Working Directory

Derive a short folder name from the user's requirements:

1. Extract the page name or a 2-4 word summary from $ARGUMENTS
2. Convert to kebab-case (e.g., "Candidate Tracker" → candidate-tracker)
3. Create the folder: mkdir -p <folder-name>
4. Resolve its absolute path — this is the working directory for all subsequent phases

Phase 0.5: Initialize Local-Dev Manifest

Write package.json and genpage.d.ts into the working directory so the developer can npm install and get IntelliSense, type-checking, and "go to definition" in their editor. Versions come from references/supported-dependencies.md (single source of truth: scripts/lib/supported-dependencies.js).

node "${PLUGIN_ROOT}/scripts/generate-page-manifest.js" <working-dir> <kebab-slug>

• <kebab-slug> is the same slug used for the working directory.
• Add --features charts,datepicker,timepicker (comma-separated) only when the requirements clearly call for them; otherwise omit and keep the manifest lean.
• The script is idempotent — it skips files that already exist. Pass --force to overwrite (used in regeneration flows when versions drift).
• Output is a JSON summary on stdout; pipe to stderr for visibility but do not block the workflow if the script returns non-zero — the manifest is a dev-ergonomics aid, not part of the deployed artifact.

Phase 1: Plan

⚠️ CRITICAL — you MUST invoke genpage-planner via the Task tool. You MUST NOT inline the planner's questions yourself with AskUserQuestion.

The planner is not optional or skippable. It runs:

1. Prerequisite validation (node --version, pac help version >= 2.7.0)
2. Auth verification (pac auth list, environment selection)
3. The structured "Create new / Edit existing" question (via AskUserQuestion inside the planner subagent, not here)
4. Language detection (pac model list-languages) — only on new-page path
5. Entity existence detection (pac model list-tables --search)
6. App detection (pac model list) with proper selection prompts
7. Plan-mode presentation and approval
8. Writes genpage-plan.md to the working directory

Reasons to NEVER ask "new or edit?" yourself before invoking the planner:

• You would skip prereq + auth (the planner is the only thing that runs them)
• The structured question gives the user labeled options; an inline free-text prompt forces them to guess
• The planner returns { "action": "edit" } as a contract — your inline question can't produce that signal cleanly

Even if $ARGUMENTS looks like it tells you the intent, still invoke the planner. Pass the intent in the prompt — the planner uses it to skip its own Question 1 if appropriate, but the prereq/auth/env steps still run.

Steps

1. Invoke genpage-planner via Task with the prompt below.
2. Wait for it to finish (it returns a summary).
3. If the return includes { "action": "edit" }, jump to the Edit Flow section.
4. Otherwise the planner has written genpage-plan.md. Proceed to Phase 2.

Invocation prompt

Pass a prompt that includes:

• The user's requirements: $ARGUMENTS
• The working directory (absolute path from Phase 0)
• The plugin root path: ${PLUGIN_ROOT}

Example:

You are the genpage-planner agent. Plan generative page(s) for the following requirements:

[paste $ARGUMENTS here verbatim, or "no arguments provided — gather from user"]

Working directory: [absolute path from Phase 0] Plugin root: ${PLUGIN_ROOT}

Follow the instructions in your agent file. Validate prereqs, confirm auth, ask the new/edit question via AskUserQuestion, then proceed accordingly. Write genpage-plan.md to the working directory if creating. Return the page list, entity status, app selection, and any { "action": "edit" } signal when complete.

Phase 2: Create Entities (Conditional)

Read genpage-plan.md from the working directory. Check the Entity Creation Required section.

If the section literally says "No entity creation required — all entities already exist": Skip to Phase 3.

If entities need creating:

2a. Pre-flight: az + pac + Dataverse

Entity creation runs through the plugin's Node.js Web API scripts using az for auth, and the az and pac identities should normally match. Run the consolidated pre-flight:

node "${PLUGIN_ROOT}/scripts/check-auth.js"

It returns a single JSON object:

{
  "ok"

• ok: true and identitiesMatch: true → proceed to 2b.
• ok: true and identitiesMatch: false → proceed to 2b but surface the message to the user as an inline warning ("az is X, pac is Y — WhoAmI works for now, but if entity creation later returns 403, run the suggested az login --username to align them").
• ok: false → show the message field to the user verbatim and stop the workflow. The script already includes a fix-it command for every blocker (run az login, etc.).

Capture envUrl from the result — Phase 2b passes it to the entity-builder.

2b. Invoke entity-builder

Invoke the genpage-entity-builder agent via the Task tool. Pass in the prompt:

• Path to genpage-plan.md
• Working directory (absolute path)
• Plugin root: ${PLUGIN_ROOT}
• Dataverse env URL (from pac org who)

The entity-builder reads Solution and Publisher Prefix directly from the plan's ## Environment — no need to re-thread them here.

Wait for completion. The builder writes a transactional log at <working-dir>/entity-creation-log.md for recovery on failure.

Phase 3: App Creation/Selection

Read genpage-plan.md for the app decision and the Solution line in ## Environment.

If "create new":

--solution is mandatory. pac model create errors out with "The given solution name is not valid: ()" if you omit it — its claimed "active solution" fallback does not work in practice.

--publish is mandatory. Without it the new appmodule stays in draft and the genux runtime URL errors with "app not published".

• Use the plan's Solution value verbatim. The planner always writes one (default fallback is literally Default).
• If the plan is somehow missing Solution, pass --solution Default — every Dataverse env has a built-in "Default Solution" by that unique name.

Store the new app-id for Phase 6.

If existing app-id: Use it directly. pac model create is not called, so the Solution line is informational only for this phase.

Phase 4: Generate RuntimeTypes (Conditional)

If any page uses Dataverse entities, generate the TypeScript schema:

Windows + Bash: Always use forward slashes in file paths (e.g., D:/temp/RuntimeTypes.ts).

After generating, read the RuntimeTypes.ts file to verify it generated correctly.

For mock data pages only: Skip this phase.

Phase 4.5: Connector Bindings (Conditional)

Re-probe the feature gate here — do not rely on the plan content alone. A plan authored while the flag was ON must not deploy connectors after it is turned OFF:

If it prints disabled: connectors are OFF. Skip this phase entirely — do not create or pass connectors.json, and never add --connectors on upload — regardless of what the plan's ## Connector Bindings section says. (Backstop: list-connections.js / create-connection-reference.js also fail closed with exit 3 if invoked while OFF.)

If it prints enabled: read the plan's ## Connector Bindings section and treat it as bindings only when it contains an actual binding table (a | Logical Name | … header with at least one data row). If the section is No connector bindings., empty, missing, or malformed, treat the page as having no connectors and skip this phase.

When there are real bindings, the genpage-connector-builder agent already wrote <working-dir>/connectors.json during planning — verify it exists and matches the plan table. If it is missing, derive it from the plan table as a bare JSON array (never the { "connectorBindings": [...] } object wrapper — that is the deployed page config.json shape that pac writes):

Do not write connection IDs into connectors.json — the importing maker/admin fills env-specific ConnectionId values through solution deployment settings.

Phase 5: Build Pages (Parallel)

Read genpage-plan.md and extract the pages table.

5a. Validate the plan before dispatch

Before invoking any builders, verify:

• At least one page exists in the ## Pages table
• Every page has a ### [Page Name] subsection in ## Per-Page Specifications
• All filenames in the ## Pages table are unique. If any are duplicated, rewrite the plan appending -1, -2, etc. before dispatch. Duplicate filenames cause silent last-writer-wins data loss under parallel execution.

See ${PLUGIN_ROOT}/references/plan-schema.md for the full contract.

5b. Single-page fast path (skip Task dispatch when N=1)

If the plan's Pages table contains exactly one row, do NOT dispatch a Task subagent. Inline the page-builder workflow directly in the orchestrator:

1. Read ${PLUGIN_ROOT}/references/rules.md
2. Read the sample listed in the plan's ## Relevant Samples
3. Only when the plan's ## Connector Bindings section contains an actual binding table (a | Logical Name | … header with at least one data row), also read ${PLUGIN_ROOT}/references/connectors.md. Treat a No connector bindings. sentinel, or an empty/missing/malformed section, as having no connectors (same contract as Phase 4.5 and genpage-page-builder).
4. If the plan's Per-Page Specification has Needs caching: true, also read ${PLUGIN_ROOT}/references/data-caching.md
5. If the plan's ## Environment indicates non-English languages, also read ${PLUGIN_ROOT}/references/localization.md
6. Read genpage-plan.md (already in working directory) and RuntimeTypes.ts if Data mode is dataverse
7. Write the .tsx file to <working-dir>/<filename>.tsx following all rules
8. After writing, Grep every named import from @fluentui/react-icons against ${PLUGIN_ROOT}/references/verified-icons.txt (one Grep per name). Rewrite any unverified names with the closest verified alternative; do not load the full icon list into context
9. Proceed to Phase 6

This saves ~5-15s of Task overhead and ~3K tokens that would otherwise be duplicated in a subagent context.

5c. Multi-page: invoke page-builders in parallel

If the plan's Pages table contains 2+ rows, invoke a genpage-page-builder agent via the Task tool per page. Fire all invocations in a single message for parallel execution.

For each page, pass a prompt that includes:

• Page name (e.g., "Candidate Tracker")
• Target file name (e.g., "candidate-tracker.tsx")
• Absolute path to genpage-plan.md
• Data mode (see below) — either a RuntimeTypes path or an explicit mock flag
• Working directory
• Plugin root: ${PLUGIN_ROOT}

For Dataverse pages, include the RuntimeTypes line:

You are the genpage-page-builder agent. Generate the [Page Name] page.

• Target file: [filename].tsx
• Plan document: [absolute path to genpage-plan.md]
• Data mode: dataverse
• RuntimeTypes: [absolute path to RuntimeTypes.ts]
• Working directory: [absolute path from Phase 0]
• Plugin root: ${PLUGIN_ROOT}

Follow the instructions in your agent file. Write [filename].tsx and return your result when done.

For mock data pages, omit the RuntimeTypes line and set Data mode: mock:

You are the genpage-page-builder agent. Generate the [Page Name] page.

• Target file: [filename].tsx
• Plan document: [absolute path to genpage-plan.md]
• Data mode: mock
• Working directory: [absolute path from Phase 0]
• Plugin root: ${PLUGIN_ROOT}

Follow the instructions in your agent file. Write [filename].tsx and return your result when done.

Wait for all page-builder tasks to complete before proceeding.

Phase 6: Deploy

For each .tsx file produced, deploy to Power Apps.

If Phase 4.5 wrote <working-dir>/connectors.json, first pre-flight the active PAC CLI:

The help output must contain --connectors. If it does not, stop and surface: "connector deploy requires a pac build with pac model genpage upload --connectors — build from PowerPlatform-Scale-AdminTools or update pac." Do not silently drop bindings.

Connector deployment matrix:

• Create (new page): include --connectors "<working-dir>/connectors.json" with the first upload --add-to-sitemap.
• Edit — connectors changed, added, or one removed: write the full desired binding set to connectors.json and include --connectors with upload --page-id <id> (full replace).
• Edit — no connector change: omit --connectors; pac preserves existing bindings. Never pass a stale or empty file on an unrelated edit.
• Delete all connectors: write [] to connectors.json and pass --connectors so pac clears the page's connectorBindings.

Copy the upload commands below exactly — --app-id, --code-file, --prompt, --agent-message are all required and must use these exact flag names.

Log the full command verbatim into workflow-log.md under a ## Phase 6 — Deploy section before invoking it. Including --prompt and all other flags. The eval harness greps the log for these tokens — a terse summary like Command: pac model genpage upload --add-to-sitemap will fail the --prompt scoping assertion. Format:

When connector bindings are present, the logged command must also include --connectors "<working-dir>/connectors.json".

--prompt semantics

• First upload (--add-to-sitemap, no --page-id): full page description from plan's ## User Requirements.
• Any subsequent upload (--page-id, no --add-to-sitemap): delta only — the changes in this upload, written like a commit message, never a re-statement of the original.

Applies in Phase 6 updates, Phase 6.5 PAGEREF re-uploads, Phase 7.5 fix re-deploys, and the entire edit flow.

For Dataverse entity pages (first upload — create):

Omit the --connectors line when Phase 4.5 did not write connectors.json.

For mock data pages: Same but omit --data-sources.

For updating existing pages (subsequent upload):

Use --page-id, omit --add-to-sitemap, and scope --prompt to the delta only:

For updates, include the --connectors line only when this upload intentionally replaces or clears connector bindings; otherwise omit it to preserve the deployed page's current bindings.

Phase 6.5: Navigation Fix-Up (Multi-Page Only)

Runs only when the plan has 2+ pages AND any built .tsx contains a PAGEREF_ token. Page-builders emit pageId: "PAGEREF_<filename-without-tsx>" as a placeholder because GUIDs don't exist until after Phase 6 (see Rule 13). This phase substitutes the real GUIDs.

Steps

1. Build filename-without-tsx → page-id map from Phase 6 upload output.

2. Sort keys by length descending so PAGEREF_pet can't match inside PAGEREF_pet-gallery.

3. For each .tsx in <working-dir>/*.tsx (top level only, no recursion), replace every quoted "PAGEREF_<name>" (must be in double quotes — that's the format page-builders emit) with "<page-id-guid>".

4. If a placeholder doesn't match any map key (typo, missing sibling), stop and report — never silently ship the literal string.

5. Re-upload only the files that had at least one replacement. Use the update form of pac model genpage upload (--page-id, no --add-to-sitemap). Per the "--prompt semantics" rule in Phase 6, this is an update, so --prompt describes the delta only — not the original page description:

   pac model genpage upload `
     --app-id <app-id> `
     --page-id <page-id-from-Phase-6> `
     --code-file <working-dir>/<file>.tsx `
     --data-sources "entity1,entity2" `
     --prompt "Resolve cross-page navigation placeholders to real page GUIDs (post-deploy fix-up)" `
     --model "<current-model-id>" `
     --agent-message "Replaced PAGEREF_<name> tokens with actual page IDs returned by Phase 6"

Pages with no PAGEREF_ strings need no second upload.

Phase 6.7: Solution Packaging (ALM, optional)

Runs only when the plan's ## Solution Packaging has Package into solution: true. Adds the deployed app, the GenPage(s), and any connection references to the target solution so they travel cross-environment.

1. Ensure the solution exists (create via scripts/create-solution.js if needed).
2. Add the app + GenPage(s) + connection references (pass the page-id(s) returned by Phase 6 as --page-ids — the GenPage is added explicitly, it does NOT travel with the app on its own): node ${PLUGIN_ROOT}/scripts/add-page-to-solution.js <envUrl> <solutionUniqueName> <app-id> --page-ids "<page-id1,page-id2>" --connection-refs "<logicalName1,logicalName2>"
3. Log the command + result to workflow-log.md.

Cross-env note (verified 2026-07-10): the app (80) pulls the sitemap (62); the GenPage uxagentproject (10372) is added explicitly and pulls its uxagentprojectfile rows (10373, incl. config.json with connectorBindings); each connectionreference (10158) is added so bindings resolve. At import the deployer supplies env-specific ConnectionId per connection reference via pac solution create-settings + pac solution import --settings-file.

Phase 7: Verify in Browser (Optional)

After successful deployment, ask the user via AskUserQuestion:

"Would you like to verify the page(s) in the browser using Playwright?"

Options: Yes, verify in browser / Skip verification

• If the user picks Skip verification → jump to Phase 8.
• If the user picks Yes → read ${PLUGIN_ROOT}/skills/genpage/verify-flow.md for the full Playwright verification workflow (navigate, structural verification including below-the-fold, interactive testing, screenshots, fix-and-redeploy). The orchestrator only loads that file on demand to keep context lean when verification is skipped.

Phase 8: Summary

By Phase 8 the workflow-log.md should already contain Phase 0 through Phase 7 sections written incrementally — the planner writes Phase 1 inside its agent context, you (the orchestrator) write Phase 0 / 0.5 / 3 / 4 / 6 / 6.5 / 7 as each runs, and the entity-builder and page-builder agents append their own Phase 2 / 5 sections when invoked.

In Phase 8, append a final ## Phase 8 — Summary section to the same file:

## Phase 8 — Summary
 
| Page | File | Entities | Status |
|------|------|----------|--------|
| <Name> | <file>.tsx | <entities or "mock data"> | Deployed |
 
- App: <name> (<app-id>)
- Entities created: <list, or "none">
- Browser verification: <skipped | confirmed | failed: <reason>>

The log MUST contain command-level entries for every prereq / auth / question / upload / script invocation — not just outcome summaries. The eval harness greps the log for tokens like node --version, pac auth list, AskUserQuestion, EnterPlanMode, --prompt, check-auth.js, etc. A decision-only log (e.g., Decision: new page without the underlying AskUserQuestion) will fail Layer 1 assertions even when the agent's behavior was correct.

Then present a final summary to the user:

## Genpage Complete
 
| Page | File | Entities | Status |
|------|------|----------|--------|
| [Name] | [file].tsx | [entities or "mock data"] | Deployed |
 
App: [app name] ([app-id])
Screenshots: [if verification was done]
Next steps: Share with team, iterate on design, create additional pages

Edit Flow

For the edit flow (triggered when the genpage-planner returns { "action": "edit" }), see edit-flow.md in this folder.

The edit flow has its own 8 phases (Edit Phase 1-8): discover and select target app + page via pac model list + pac model genpage list, download, generate RuntimeTypes if needed, invoke genpage-edit-planner, apply the edit inline, deploy, verify, summarize.
