Generate a Canvas App

Generate a complete Power Apps canvas app for the following requirements:

$ARGUMENTS

Overview

This skill uses two specialist agent definitions (read from the agents/ folder):

1. canvas-app-planner — discovers controls and data sources, designs the app, presents a screen plan for approval, writes a shared plan document
2. canvas-screen-builder — writes exactly one screen's YAML; multiple builders run sequentially after the plan is approved

You coordinate the agents and own the compilation + error-fixing loop after all screens are written.

Plugin root: the directory containing skills/, agents/, and references/

Phase 0 — Create App Folder

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

---

Phase 1 — Plan (Planner Agent)

Read these files before planning:

• ../../references/TechnicalGuide.md
• ../../references/DesignGuide.md
• ../../agents/canvas-app-planner.md

Adopt the role of the canvas-app-planner and follow every step in that file, with:

• User requirements: $ARGUMENTS
• Working directory: the absolute path resolved in Phase 0
• Plugin root: the directory containing skills/, agents/, and references/

Complete ALL steps in the planner agent file, including:

• Using the already loaded TechnicalGuide.md and DesignGuide.md
• Calling list_controls, list_apis, list_data_sources
• Presenting the screen plan to the user and waiting for approval
• Writing canvas-app-plan.md and App.pa.yaml to the working directory

Do not proceed to Phase 2 until the user approves the plan.

---

Phase 2 — Build (Screen Builder Agent, One Screen at a Time)

After the planner completes, read canvas-app-plan.md from the working directory.

Extract the screen list from the ## Screens table.

For each screen in the list, in sequence:

1. Read the builder agent definition: ../../agents/canvas-screen-builder.md
2. Adopt the role of canvas-screen-builder for this screen
3. Follow every step in that file with:
   • Screen name
   • Target file name
   • Plan document: <working-directory>/canvas-app-plan.md
   • Working directory: the absolute path from Phase 0
4. Write [ScreenName].pa.yaml to the working directory before moving to the next screen

---

Phase 3 — Validate and Fix

After all screen files are written, call compile_canvas on the working directory.

On success: Proceed to Phase 4.

On failure: For each error in the output:

1. Read the referenced .pa.yaml file
2. Fix the error
3. Call compile_canvas again

Repeat until compile_canvas reports no errors.

---

Phase 4 — Summary

Delete canvas-app-plan.md:

rm <working-directory>/canvas-app-plan.md

Present final summary:

App generation complete.
