Resumen
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.

Capturing visual evidence
Root AGENTS.md 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/prandcompose-preview/mainbranches where they cover the change. - Scan
.github/workflowsfor 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>
--rerun matters. A failed render leaves .error.json sidecars that count as task
outputs, so composePreviewRender goes UP-TO-DATE and re-reports the stale
failure. PNGs land under <module>/build/compose-previews/renders/.
The samples consume the plugin through includeBuild("gradle-plugin"), so a plugin
edit is picked up with no publish step.
For the before side, render at the base commit (git stash, or a worktree at
origin/main) into a separate directory before rendering the head.
The Android lane needs an SDK; the Desktop lane does not
- Compose Desktop renders headlessly — no
DISPLAY, X server orxvfb. Skia's software path draws offscreen. If a desktop render looks broken in a sandbox, it is almost never the windowing system: check the JDK 17 toolchain and the native deps first, per Common commands anddocs/DESKTOP_NATIVE_DEPS.md. - The Android/Robolectric lane needs an Android SDK, which a fresh container
does not have.
scripts/install.sh --android-sdkinstalls it (and a JDK when./gradlewreports "Unable to download toolchain"). The traps that cost a whole session — chiefly that the platform package forcompileSdk = 37isplatforms;android-37.0, notandroid-37, and that the wrong name fails the entiresdkmanagerinvocation it appears in, taking the SDK 36 packages down with it — are written up under Bringing up a fresh sandbox. Read that before improvising. Cold end-to-end run is about 3 minutes.
Surfaces the @Preview pipeline does not reach
- VS Code panel UI (
src/webview/,media/preview*.css) has its own capture path: the preview-harness boots the real<preview-app>bundle headlessly against fixture JSON. Loop and fixture authoring are inpreview-harness/README.md; seed fixtures aregrid-defaultanda11y-findings. - A semantics overlay has a renderable proxy: the
compose/semantics-wireframeSVG. - Anything genuinely uncapturable here (a three.js webview in a headless
container): say so explicitly in the PR body, embed a proxy if one exists, and
state how a human or CI verifies it visually. Then treat "nothing renders this
yet" as a gap to close in the same or a fast-follow PR — register a fixture or a
@Previewwith the preview-harness so the next change to that surface is diffed automatically.
Getting the pixels into the PR
- Commit the PNGs you intend to cite to your working branch and push.
- Embed them as markdown images whose URLs are commit-SHA-pinned
raw.githubusercontent.comlinks to those pushed files — the same form the diff bot uses. This is not just convention: awhose host is not a GitHub origin has its!stripped before it reaches the API, silently, so a deployment URL or a CDN link arrives as a bare link and the evidence is gone. Committing and citing the raw URL is what makes the image survive. - Write
plainly and leave any backticks that appear alone. They are injected between the agent and GitHub, and thePR Body Syntaxworkflow repairs them in place. The three cases it does not cover — review comments, destinations mangled past recognition, and a picture that still did not render — are in PR workflow. - Verify the pixels actually render on the published page before claiming evidence.
WebFetchcaches per URL for ~15 minutes; bust it with a throwaway query parameter rather than chasing a bug you already fixed.
A before/after pair whose two images look identical is a finding, not a failure — either the change is not visual, or the render did not pick it up. Say which.

# 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>
```
`--rerun` matters. A failed render leaves `.error.json` sidecars that count as task
outputs, so `composePreviewRender` goes `UP-TO-DATE` and re-reports the stale
failure. PNGs land under `<module>/build/compose-previews/renders/`.
The samples consume the plugin through `includeBuild("gradle-plugin")`, so a plugin
edit is picked up with no publish step.
For the **before** side, render at the base commit (`git stash`, or a worktree at
`origin/main`) into a separate directory before rendering the head.
## The Android lane needs an SDK; the Desktop lane does not
- **Compose Desktop renders headlessly** — no `DISPLAY`, X server or `xvfb`. Skia's
software path draws offscreen. If a desktop render looks broken in a sandbox, it
is almost never the windowing system: check the JDK 17 toolchain and the native
deps first, per
[Common commands](../../../docs/AGENT_GUIDE.md#common-commands) and
[`docs/DESKTOP_NATIVE_DEPS.md`](../../../docs/DESKTOP_NATIVE_DEPS.md).
- **The Android/Robolectric lane needs an Android SDK**, which a fresh container
does not have. `scripts/install.sh --android-sdk` installs it (and a JDK when
`./gradlew` reports "Unable to download toolchain"). The traps that cost a whole
session — chiefly that the platform package for `compileSdk = 37` is
**`platforms;android-37.0`**, not `android-37`, and that the wrong name fails the
entire `sdkmanager` invocation it appears in, taking the SDK 36 packages down with
it — are written up under
[Bringing up a fresh sandbox](../../../docs/AGENT_GUIDE.md#important-constraints).
Read that before improvising. Cold end-to-end run is about 3 minutes.
## Surfaces the `@Preview` pipeline does not reach
- **VS Code panel UI** ([`src/webview/`](https://github.com/yschimke/compose-preview-vscode/blob/main/src/webview/), `media/preview*.css`) has
its own capture path: the preview-harness boots the real `<preview-app>` bundle
headlessly against fixture JSON. Loop and fixture authoring are in
[`preview-harness/README.md`](https://github.com/yschimke/compose-preview-vscode/blob/main/preview-harness/README.md#agent-workflow);
seed fixtures are `grid-default` and `a11y-findings`.
- **A semantics overlay** has a renderable proxy: the `compose/semantics-wireframe`
SVG.
- **Anything genuinely uncapturable here** (a three.js webview in a headless
container): say so explicitly in the PR body, embed a proxy if one exists, and
state how a human or CI verifies it visually. Then treat "nothing renders this
yet" as a gap to close in the same or a fast-follow PR — register a fixture or a
`@Preview` with the preview-harness so the next change to that surface is diffed
automatically.
## Getting the pixels into the PR
1. Commit the PNGs you intend to cite to your working branch and push.
2. Embed them as markdown images whose URLs are **commit-SHA-pinned**
`raw.githubusercontent.com` links to those pushed files — the same form the diff
bot uses. This is not just convention: a `` whose host is not a
GitHub origin has its `!` stripped before it reaches the API, silently, so a
deployment URL or a CDN link arrives as a bare link and the evidence is gone.
Committing and citing the raw URL is what makes the image survive.
3. Write `` plainly and **leave any backticks that appear alone**. They
are injected between the agent and GitHub, and the `PR Body Syntax` workflow
repairs them in place. The three cases it does not cover — review comments,
destinations mangled past recognition, and a picture that still did not render —
are in [PR workflow](../../../docs/AGENT_GUIDE.md#pr-workflow).
4. Verify the pixels actually render on the published page before claiming evidence.
`WebFetch` caches per URL for ~15 minutes; bust it with a throwaway query
parameter rather than chasing a bug you already fixed.
A before/after pair whose two images look identical is a finding, not a failure —
either the change is not visual, or the render did not pick it up. Say which.
