The correct option is To satisfy GitHub Marketplace requirements so the action can be published immediately without manual review.

GitHub Marketplace expects an action repository to contain only the action metadata, the implementation code, and the files that are strictly required to run it. Meeting this packaging requirement aligns the project with Marketplace policies and enables automatic publishing without waiting for a human to review the repository. The primary outcome is compliance that unlocks streamlined publishing rather than performance gains or external integrations.

To reduce the repository footprint so developers can clone it more quickly is not the primary outcome. While a smaller repository can clone faster, the checklist requirement exists to satisfy Marketplace rules and allow automated publishing.

To improve the repository's placement in GitHub search results is not correct because search ranking is not determined by stripping the repository to only action files. The requirement targets Marketplace compliance and publishing flow, not search optimization.

To integrate publishing with Cloud Build in Google Cloud projects is unrelated. Marketplace publishing is a GitHub process and is not tied to Google Cloud Build integrations.
