Writes and refines a repository's README.md in a concise, Nuxt-inspired documentation style: sections chosen from what the repository actually contains, scannable feature bullets, emoji-anchored headings, and a banner, badges, and docs links only when the repository provides them. Use this skill when the user wants a README created, rewritten, restructured, tightened, polished, or brought up to date after the code changed, when they want a project's front page documentation improved or made consistent with their other repositories, or when they point you at a repo and ask what its README should say, even if they never use the word "README". Applies to repositories in any language or framework. Do not use it for changelogs, release notes, API reference, contributing guides, standalone documentation pages, or marketing copy.
