Lumina-Note

Generate images for the user's vault — pick the right provider, gather reference images from notes when relevant, write the result to assets/generated/, and surface the markdown reference. Use this when the user asks for any picture, illustration, mood image, poster, or visual companion to a note.

Synthesize a single source note into the vault's wiki/ folder — read the source, find or create the right wiki entry, write it back with proper frontmatter and source links. Used by Lumina's background wiki manager when a note changes.
