Interactive AdaUI forms

Use Studio's advertised A2UI v0.9.1 Ada forms catalog to collect configuration. Emit JSONL envelopes inside a fenced a2ui block; stream complete lines, keep prose outside the block, and end the turn once the user can submit.

For an NPC workflow, collect name, role, health, greeting, and a repeatable-dialog toggle using absolute /npc/... bindings. Use ChoicePicker with a string-valued role and labeled choices, and Slider with health bounds and step. Put a required name check on the field and submit button, and an inclusive numeric range check on the slider and submit button. Checks use the advertised required/range subset; never invent executable validation functions. A Generate preview button should emit generate_npc_preview with those paths in action.event.context.

On the next [A2UI user action], read current submitted values and create a new npc-preview surface containing a dialog title, greeting, and choice buttons. Use host-owned action names such as continue_dialog or close_dialog. Preserve existing surface/component IDs when updating, and use deleteSurface before reusing an existing surface ID. Validation failures are reported in the chat's interface error state and correction context on the following prompt.

Do not execute or interpolate user text as code. Do not write the .ui file: users choose Open in UI Designer, refine through normal designer controls, and save through Studio's document workflow. The ACP session and existing project tools remain the transport and authoring integration.

Reusable scene tools

When asked for a spawner, color editor, or a tool inside chat, use the host's advertised local actions rather than asking the model to execute the change after submission. Read editor.scene.get before presenting a card. Bind the returned revision at /scene/revision, pass expectedRevision:{path:"/scene/revision"} and revisionBinding:"/scene/revision" on every scene action.

Use editor.scene.spawn for an existing NPC subtree with entityID, count and spacing; editor.scene.setColor for entityID/typeName/field/color; or editor.scene.apply for structured operation batches. Keep the scene path fixed. Use editor.color.pick with binding:"/color" and value:{path:"/color"} plus a HEX TextField to choose a color. A separate Apply button applies it to the scene. Do not apply these operations before the user clicks. The host performs the action without a new model turn and exposes Undo. These cards work on desktop and iPhone; iPhone exports .ui to its source editor instead of the desktop visual designer.
