## What it does

This is a skill-only companion to the native `create-canvas` skill in a canvas-capable Copilot host. It ships setup guidance for Microsoft Canvas Toolkit and two starters: a counter and a read-only Azure resource-group viewer. Its own skill is called `create-canvas-app`. If the host lacks `create-canvas`, the plugin will not supply it.

You need Node.js 22+ and a usable toolkit package, plus a Copilot host that can run canvases. The Azure starter also wants Azure CLI 2.61+ and read permission on the subscription. Setup takes either one exact npm version or a local `.tgz`; it installs no dependencies and never contacts Azure. Point it at an output folder that already exists and it refuses instead of overwriting.

Install the finished output from `dist/` following the generated README and reload the provider. A plain browser refresh will not pick up rebuilt provider code; a build-ID warning means something is out of sync. The Azure app sits idle until you load the CLI profile, pick a subscription and hit the resource-group listing. It never signs in or writes anything in Azure on its own. The plugin counts calls to `create-canvas-app` — skill name, invocation kind, plugin version, timestamp — and keeps them up to 30 days; prompts, project files and source are not sent.

## Requirements
- Works with: Azure

## Install

### GitHub Copilot (native platform)

**Command from the source**
```bash
copilot plugin install canvas-authoring@awesome-copilot
```

## When to use it
- scaffold a canvas app with a working counter starter
- build a read-only viewer for Azure resource groups
- wire Microsoft Canvas Toolkit into the native `create-canvas` skill
- smoke-test the generated app with `npm run smoke`
- pick an Azure subscription by hand and list its resources

## Example prompts
- Use the native `create-canvas` skill and the `create-canvas-app` companion's counter starter to build a canvas.
- Build a read-only Azure canvas that lists resource groups, using the native `create-canvas` skill and the Azure starter.
- Run the build and `npm run smoke` in the generated app before installing `dist/`.

# Canvas authoring plugin

Create a canvas app with the Microsoft Canvas Toolkit. This **skill-only
companion** gives the host's native `create-canvas` workflow toolkit setup
and a counter or read-only Azure resource-group starter; installing it does
not open a canvas.

## Install

If your GitHub Copilot host shows the **awesome-copilot** marketplace, open
**Customize → Plugins** and install **canvas-authoring**. Its
[listed 0.1.1 package](https://github.com/microsoft/azure-dev-tools/tree/a6d394bbaa6fb1dc0151257a85cbac0de772b138/plugins/canvas-authoring)
is a skill-only companion, not a canvas extension. If the marketplace is
missing, add it first:

```sh
copilot plugin marketplace add github/awesome-copilot
copilot plugin install canvas-authoring@awesome-copilot
```

For an approved local export, run:

```sh
copilot --plugin-dir "<export-directory>/plugins/canvas-authoring"
```

Install the exported plugin, not this source folder.

You need a canvas-capable Copilot host with the native `create-canvas` skill,
Node.js 22+, and an available toolkit package; the Azure starter also needs
Azure CLI and subscription read access. See [requirements](#requirements).

## Try it

Ask your agent to **Build a read-only Azure canvas that lists resource
groups. Use the native create-canvas skill and the create-canvas-app
companion's Azure starter.** Choose a compatible toolkit package and project
location when prompted. For a non-Azure example, ask for the counter starter.

## What you can do

- Generate a native canvas scaffold with a working counter starter.
- Start a read-only Azure resource-group viewer with explicit subscription choice.
- Build and smoke-test the generated app before installing its complete output.

## Prompts to try

> Use the native create-canvas skill and the create-canvas-app companion to build a counter canvas.

> Build a read-only Azure canvas that lists resource groups. Use the native create-canvas skill and the create-canvas-app companion's Azure starter.

## Requirements

- A canvas-capable GitHub Copilot host with its installed `create-canvas` skill.
  The plugin does not replace or install that host skill.
- Node.js 22+ (24 recommended) and npm.
- The exact `@microsoft/canvas-toolkit@0.1.0-preview.2` release exporting
  `@microsoft/canvas-toolkit/build`, once published, or an approved local
  `.tgz` containing that API. Do not treat a missing `/build` export as success.
- For live Azure reads: Azure CLI 2.61+ and permission to read the subscription.

## Usage data

The plugin counts how often its `create-canvas-app` skill is invoked. Each
count records the skill name, how it was invoked, the plugin name and version,
and a timestamp. Usage telemetry may include a pseudonymous account identifier
to understand usage over time; it is retained for up to 30 days. The plugin
does not send prompts, project files or source code.

## Create an app

The agent creates the native scaffold, generates the source app, and connects
the copied host entry. You choose the project location and toolkit package.

Setup accepts one exact npm version or one local tarball. It does not install
dependencies or contact Azure, and it refuses existing output directories
rather than overwriting files. For command-line setup, see the
[skill instructions](skills/create-canvas-app/SKILL.md).

## Build and run

In the generated app:

```sh
npm install
npm run build
npm test
npm run smoke
```

`smoke` is available in the Azure starter. It uses installed Chrome, or the
executable specified by `CANVAS_BROWSER`, with labelled synthetic data.
Keep `package-lock.json` and use `npm ci` for later installs.

Follow the generated README and host skill to install the complete `dist/`
directory and reload the provider. A browser refresh does not load rebuilt
provider code; a build-ID warning indicates a mismatch.

The Azure app does nothing until you act: load the CLI profile, select a
subscription, then choose **List resource groups**. It never signs in, chooses
