Capture the before/after rendered PNGs a UI-affecting PR in this repository needs as visual evidence, including bringing an Android SDK up in a fresh sandbox. Use when a change touches a Compose @Preview, a catalog, the VS Code webview, an overlay, a theme, an icon or a fixture, and the PR body needs real pixels.

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

# Capturing visual evidence

Root [`AGENTS.md`](../../../AGENTS.md#pr-workflow) says a UI-affecting PR must carry
before/after evidence as **embedded, viewable images** — describing an image, or
deferring to the diff bot's auto-comment, does not count. This is how to produce
them here.

## Check what already exists first

Rendering is not free. Before capturing anything:

- Read the sticky `<!-- preview-diff -->` comment on the PR — CI may already have
  rendered and diffed exactly the surface you changed.
- Reuse renders published on the `compose-preview/pr` and `compose-preview/main`
  branches where they cover the change.
- Scan [`.github/workflows`](../../../.github/workflows) for the preview-diff CI
  this repo already runs, and cite it.

The bot's comment is a convenience, not a substitute: your PR body still needs
*your* change's before/after embedded in it.

## Rendering

Whole sample modules:

```
./gradlew :samples:android:composePreviewRenderAll
./gradlew :samples:cmp:composePreviewRenderAll
```

One preview, which is what a before/after pair usually wants:

```
./gradlew :samples:android:composePreviewRender --rerun \
  -PcomposePreview.filter=<PreviewFunctionName>
```
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add yschimke/compose-ai-tools/render-evidence@sha256:2fd4202619b65fee

The line at the top of this page pins the label git:20260906.e800532, 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.
