What it does

Generate Canvas App is an agent skill from hashgraph-online/awesome-codex-plugins. Generate a complete, visually distinctive Power Apps canvas app with YAML. USE WHEN the user wants to create, build, or generate a Canvas App or pa.yaml files.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • The user wants to create
  • Generate a Canvas App

Example prompts

  • “/generate-canvas-app”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Create App Folder
  2. Plan (Planner Agent)
  3. Build (Screen Builder Agent, One Screen at a Time)
  4. Validate and Fix
  5. Summary

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Generate Canvas App loads about 882 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 405 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~882

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.


Show full SKILL.md (170 more words)Show less

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:

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

Present final summary:

App generation complete.
