# Power Apps Generative Pages Builder

**Triggers:** genpage, generative page, create genpage, genux page, build genux, power apps page, model page
**Keywords:** power apps, generative pages, genux, model-driven, dataverse, react, fluent ui, pac cli
**Aliases:** /genpage, /gen-page, /genux

## Overview

This skill orchestrates 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`.
   May pause and return `connector_discovery_required` (see 2).
2. **`genpage-connector-builder`** — top-level orchestrator dispatch for connector
   feature-gating and discovery; writes `connector-bindings.md` + `connectors.json`.
   Runs **after** the planner has resolved create-vs-edit and the target environment
   (discovery is mutating), then the planner is re-invoked with its contract.
3. **`genpage-entity-builder`** — creates Dataverse entities (tables, columns,
   relationships, choices, sample data) via the plugin's Node.js Web API scripts
4. **`genpage-page-builder`** — generates one complete `.tsx` file per page; multiple
   builders run in parallel for multi-page requests

**Edit flow:**

5. **`genpage-connector-builder`** — top-level orchestrator dispatch when an edit adds,
   replaces, discovers, or clears connector bindings; preserves unchanged bindings
   when the feature gate is OFF
6. **`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 connector dispatch, app creation,
RuntimeTypes generation, deployment, browser verification, and the inline
application of planned edits.

- **Sample pages**: [samples/](../../samples/)

## 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>` (bash/PowerShell; on cmd use `mkdir <folder-name>`,
   which has no `-p` and errors if the folder exists)
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`).

```bash
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 > 2.10.0)
> 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.

1. Invoke `genpage-planner` via `Task` with the pr
