Author Microsoft Power Apps canvas app source as unpacked *.fx.yaml + CanvasManifest.json so an agent can generate Power Fx screens that pac canvas pack and pac solution pack will accept. Covers the Src/ YAML control tree, Power Fx formula syntax, App OnStart, screens, data sources, components, and the round-trip with pac canvas unpack/pack.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Power Apps Canvas App YAML
> Purpose: emit canvas app source that round-trips through `pac canvas unpack` / `pac canvas pack` and packs into a solution under `CanvasApps/`.
## When to Use
- Generating a canvas app (forms, galleries, screens over Dataverse or other data) from a PRD-LOWCODE
- Editing screen logic or controls in an existing unpacked app
- Reviewing Power Fx before packaging
## On-Disk Layout (after `pac canvas unpack`)
```
CanvasApps/
<prefix>_<appname>_<DocumentUri>/
CanvasManifest.json # app metadata, dependencies, data sources, app-level Power Fx
Src/
App.fx.yaml # App.OnStart, App.Formulas, named formulas
<ScreenName>.fx.yaml # one file per screen, control tree + Power Fx
Component/ # reusable canvas components
Assets/ # images, media
Connections/ # data source connection metadata
DataSources/ # *.json per data source (table, connector)
```
`pac canvas pack --sources ./Src --msapp build/app.msapp` rebuilds the `.msapp`, which `pac solution pack` then embeds.

How to install
mdr add jnpiyush/agentx/canvas-app-yaml@sha256:e9b2d87c6fd7f088The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
