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.
Compose Preview CI is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/compose-preview-ci/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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 when preview CI is too slow and needs change-scoping or parallel jobs. Pairs with the compose-preview and compose-preview-review skills.
The Compose Preview CI Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 188,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
