Discover, preview, and insert CircleCI docs reusable includes: AsciiDoc partials and shared code examples. Propose when new or existing content should become a shared partial or example, then create it and replace duplicates after confirmation. Use this skill whenever the user mentions partials, examples, includes, reusable snippets, /partials, or /examples, and whenever you are writing or editing .adoc pages that need shared navigation steps, notes, tips, FAQs, troubleshooting, resource tables, runner setup, or shared config snippets. Other docs-authoring skills must follow this skill instead of copying reusable content by hand.
