xb-add-spatial-ui

Build spatial UI in XR Blocks. Use when adding cards, overlays, panels, text, controls, model-viewer interfaces, layout, styling, themes, or UI placement with the built-in UI system.

xb-add-interactions

Design and implement XR Blocks interactions. Use when adding selection, hover, direct touch, grab, gestures, event ownership, propagation, automatic manipulation, or physics-driven object behavior.

xb-add-ai

Add AI behavior to an XR Blocks application. Use when implementing Gemini or OpenAI queries, Gemini Live voice or vision, generated images, scene-grounded responses, or model-requested tools with an observable XR outcome.

xb-add-world-sensing

Connect physical-world sensing to XR Blocks application state. Use when adding planes, scene meshes, depth, occlusion, world collision evidence, object or human recognition, face tracking, segmentation, or agent-facing scene context.

xb-build-app

Build or extend a complete XR Blocks application. Use when the request concerns an app scaffold, a whole experience, several SDK areas, or an end-to-end simulator or XR handoff rather than one focused subsystem.

xb-contribute-sdk

Complete an XR Blocks SDK change across implementation, runtime wiring, public exports, proof, build output, examples, and canonical documentation. Use when editing the XR Blocks repository rather than an application that consumes it.

xb-debug-app

Debug and repair XR Blocks applications. Use when an app fails to build or run, produces incorrect UI, interaction, sensing, or rendering behavior, differs between simulator and device, leaks resources, or contains obsolete SDK patterns.

xb-anchors

Pin content to a real place with WebXR spatial anchors, and bring it back in a later session. Use when virtual content must stay put as the headset refines its map of the room, or when an app should remember where things were left. Covers `enableAnchors()`,…
