Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
12 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by korchard333 on GitHub. Read the source before you install it.

Installation

Install the Canvas Apps AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/korchard333/claude-power-platform-community/tree/main/.claude/skills/canvas-apps
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/korchard333/claude-power-platform-community.git /tmp/claude-power-platform-community
mkdir -p .claude/skills
cp -r /tmp/claude-power-platform-community/.claude/skills/canvas-apps .claude/skills/canvas-apps

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Canvas Apps in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Canvas Apps on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Canvas Apps is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Skill: Canvas Apps Development

When to Use

Trigger when building, reviewing, or debugging Canvas Apps — low-code Power Apps built with Power Fx formulas, connectors, and drag-and-drop controls for mobile, tablet, and web scenarios.

AI Accuracy Warning

LLMs produce less accurate Power Fx than mainstream languages (JavaScript, C#, Python) due to smaller training datasets. Always verify AI-generated Power Fx formulas — especially complex ones involving delegation, ThisItem/ThisRecord, concurrent collections, or nested If/Switch logic. Use Power Apps Test Engine to validate formulas before promoting to production.

When to Use Canvas Apps vs Alternatives

⚠️ REQUIRED: Load Sub-Files Before Implementation

SKILL.md is a summary only — it is NOT sufficient for implementation.

The detailed content (complete payloads, XML templates, working examples, edge-case handling) lives in sub-files in the same directory as this SKILL.md. Before writing any code, you MUST use read_file on the sub-files relevant to your task:

Power Fx Fundamentals — data types, core functions (CRUD, navigation, variables), named formulas, UDFs
Delegation — delegable vs non-delegable functions, limits, warning patterns, workarounds
Components & Modern Controls — component library, property types, Fluent 2 modern controls, theming
Screen Patterns & Responsive Design — master-detail, loading pattern, container layout, phone vs tablet
Offline Capabilities — LoadData/SaveData, connectivity check, offline queue + sync pattern
Connectors, Data Sources & Integration — connector types, Dataverse/SharePoint patterns, Power Automate integration, environment variables
Canvas ALM — solution-aware development, source control (pac canvas unpack/pack), co-authoring
Performance & Error Handling — Concurrent loading, optimization do's/don'ts, form validation, IfError
Power Fx Function Reference — Complete function reference by category: Text, Math, Date/Time, Logical, Table, Collection, Behavior, JSON, Environment
Power Fx Operators Reference — Arithmetic, comparison, logical, membership (in/exactin), scope (ThisItem/Self/Parent/As/@), chaining, type operators, precedence
Controls Reference — Top 15 Canvas controls (Gallery, EditForm, TextInput, ComboBox, Button, etc.) with key properties, events, patterns, modern vs classic differences

Components	`cmp[Name]`	`cmpStatusBadge`, `cmpSearchBar`
Component libraries	`lib[Name]`	`libSharedControls`

Accessibility in Canvas Apps

Set AccessibleLabel on every control
Set TabIndex for logical tab order (0 for interactive, -1 to skip)
Use Live property for dynamic content updates (screen reader announcements)
Provide sufficient color contrast (4.5:1 for text)
Ensure all functionality accessible via keyboard
Use the Accessibility Checker in Power Apps Studio: App checker → Accessibility

Anti-Patterns

Building Canvas Apps outside of solutions ("My Apps")
Direct connections instead of connection references
Hardcoded GUIDs or environment URLs
Loading entire tables without Filter or $top
Ignoring delegation warnings (blue underline in formula bar)
Using Set for table data instead of ClearCollect
Nesting ForAll with Patch for bulk operations
Using OnStart for heavy data loading without Concurrent
Naming controls with default names (Button1, Label4, Gallery3)
Not implementing error handling on form submissions
Using Navigate without Back() support (no way to return)
Embedding sensitive values in formulas (visible in .msapp file)
Using the Dynamics 365 connector (deprecated) — use the native Microsoft Dataverse connector instead
Using the Dataverse (legacy) connector — use the current Microsoft Dataverse connector

Frequently asked questions

What does the Canvas Apps AI skill do?

Why use Canvas Apps on TypingMind?

Because you install it once and use it with any model. Canvas Apps is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Canvas Apps in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/korchard333/claude-power-platform-community/tree/main/.claude/skills/canvas-apps. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Canvas Apps?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Canvas Apps?

As many as you like. As long as a model supports skills, you can use Canvas Apps with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Canvas Apps AI skill free?

Yes. It is published on GitHub by korchard333 under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
