Set up or repair GitHub Actions CI that renders Compose @Preview composables and posts before/after diff comments on pull requests. Use when wiring preview diffs into a repo for the first time, when preview comments don't appear on fork PRs (the two-stage render/publish split), when migrating off the legacy preview-baselines / preview-comment / a11y-report / notification-previews actions, when a run fails with "no modules have the compose-preview plugin applied" (CLI/plugin version skew), or…

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

# Compose Preview — CI setup

Wiring the `compose-preview` CI surface into a repository: a
`compose-preview/main` baselines branch, sticky before/after diff comments
on pull requests, and the choices that decide whether one workflow is
enough or you need two.

This skill is about **standing the pipeline up and keeping it working**.
For *reading* the diffs it produces — reviewing a UI PR, triaging a flaky
preview — see the [**compose-preview-review**](../compose-preview-review/SKILL.md)
skill. For driving the renderer by hand, see
[**compose-preview**](../compose-preview/SKILL.md).

## Source

Maintained at [github.com/yschimke/skills](https://github.com/yschimke/skills)
under `skills/compose-preview-ci/`. The composite actions described here ship
from [yschimke/compose-ai-tools](https://github.com/yschimke/compose-ai-tools);
the canonical, always-current input reference is that repo's
[`.github/actions/apply/README.md`](https://github.com/yschimke/compose-ai-tools/blob/main/.github/actions/apply/README.md).
When this skill and that README disagree, the README wins — check it before
telling a user an input doesn't exist.

How to install

The exact contents, by fingerprint
mdr add yschimke/skills/compose-preview-ci@sha256:14e1e99bc2ba6de9

The line at the top of this page pins the label git:20260905.6b93dc7, 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.
