Add a new artwork to the catalogue — the primary tool to create / catalogue / record / log ONE new work (painting, sculpture, photograph, print, drawing, video, software, NFT, performance, installation, etc.) into the artist's catalogue or inventory. TRIGGER: user shares a photo, describes a work, mentions a title, or says "add a work," "create a work," "new work / piece / artwork," "catalogue this," "record this," "put this in my catalogue / inventory." For MULTIPLE works at once, use create_works_batch instead. Only title and artist_id are required. Infer what you can (medium, date, extent, edition) and present ONE summary — never ask field by field. Wait for confirmation before calling. After creating, proactively call get_upload_url if the user mentioned an image. If the user has a CSV or spreadsheet file, direct them to raisonn.ai/import. artist_id from get_profile — never ask the user. To reach "Ready to authenticate," populate the typed Identity Eight for the work's medium_category (medium_category, extent_type/extent_value, edition_status, authentication_marker_type/authentication_marker_value, plus image via get_upload_url and, for media-native works, primary_work_file) — each field's own description carries its variants and per-category label. Ask with the medium-appropriate label, never a generic "signature" field (e.g. "Inscription" for a painting). `unsigned`/`none` are valid positive marker values. NFT: call link_wallet_challenge + link_wallet_verify first. After success, ask if they'd like to see how it looks. Then call get_work to show the visual card.
