Use when the user wants an agent-maintained knowledge wiki - creating one, ingesting source material (pptx, pdf, docx, markdown, images), asking questions of accumulated knowledge, recomposing it into blogs, LinkedIn posts, slide decks, docx or SVG images, health-checking pages, or building a personal voice profile (captured by the bundled idiolect skill; the bundled hogwash skill scans only pieces the user marks for an outside audience). Also use when a folder contains raw/.ingest-manifest.json or the user mentions "my wiki".
