Documentation Writer skill: what it does and how to install it

What it does. Helps plan and write Markdown documentation by first clarifying the document type, audience, goal and scope, then proposing an outline for approval before drafting. It applies Diátaxis principles for clarity, accuracy, user focus and consistent terminology across tutorials, how-to guides, reference and explanation pages.

When to use it. For creating or revising software documentation when the intended audience, outcome and scope need to be established first. It can use supplied Markdown files for project context, but does not consult external sources unless a link and instruction are provided.
