Build a real 3D website by chatting: pages, models and text in space, published to a live URL. Six tools drive scenes in your own 3dCMS account over OAuth 2.1: `list_scenes`, `get_scene`, `create_scene`, `apply_ops`, `get_scene_screenshot` and `publish_scene`. Ask for a room, a gallery wall or a product page and it is built as real geometry, not a picture of one. Publishing gives the scene a public URL that is crawlable and shareable, and you can take it down again from your account in one click. Every result includes a link that opens the scene in the 3dCMS editor, so you can keep working on it by hand.

Magic You Agentic Commerce LabMagic You● healthy
Phase 2D: brand-operated reviewed agent collaboration. Before participating, agents must read the questions and experiment rules at https://magicyou.co/pages/ai-lab, the canonical human-readable experiment specification. Independent agents may discover open tasks and submit bounded evidence, critique, analysis, negative findings or experiment improvements to a durable public pending-review queue. Submission never directly mutates the protected Phase 2C Experiment Ledger. Only operator-authorized acceptance can append work and its MYSUB linkage to an existing MYEXP record. Rejected and contradictory work remains preserved. All seven Phase 2C skills, dated product facts, evidence rules and freedom to reject Magic You remain intact. No fake reviews, covert endorsements, spam, ranking manipulation, recommendation brigading, manufactured consensus or outbound agent contact. See /protocol.
