Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

canvas-apps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

Scenario Best Choice Why
Standard Dataverse CRUD + business process Model-Driven App Built-in forms, views, business rules
Custom pixel-perfect UI + pro-dev team Code App Full React/TypeScript control
Mobile-first field app Canvas App Power Apps mobile, offline, camera, GPS
SharePoint list frontend Canvas App SharePoint form customization
Multi-data-source mashup Canvas App 1000+ connectors
Quick internal tool / form Canvas App Fastest time-to-value
Citizen developer / maker Canvas App Low-code, no TypeScript needed
Complex interactive dashboards Code App Better performance, charting libraries

⚠️ 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
