Widget Forms Host Adapter

The canonical agent's raw <widget>, <choices/>, and <visual-option> tags render only inside ChatCut. Never emit those tags from the published Codex or Claude Code plugin.

Semantic contract mapping

This adapter owns how plugin hosts implement a caller's host-neutral form contract. It does not decide which fields the workflow requires.

Map semantic field types as follows:

• short_text: one text input.
• explicit_consent: one explicit, initially unselected confirmation control using the caller's full localized copy. An attachment or another submitted field is never consent.
• audio_reference: plugin forms cannot record or upload media. Render the other fields, ask the user to attach the audio to the conversation, then load asset-import. Return the imported ChatCut audio assetId to the calling workflow; never return a local path, attachment URL, or raw bytes as an asset id.
• playable_single_choice: one choice surface with stable option values, localized labels, and playable media when the host supports it. Keep the value-to-label map in context when a host returns the visible label.
• playable_preview: one display-only, non-submitting audio surface using the exact caller-provided runtime media URL. Use only a host-supported safe media renderer; never emit raw <audio> HTML or expose the URL as ordinary prose.

Codex

Call the ChatCut MCP tool ask_followup_questions. Put related fields into one form, write visible text in the user's language, and stop after the call until the submitted answer appears in chat. Use the current tool schema for field and option shapes.

Map playable_single_choice to one single field with variant:"voice". Use each stable value as the option id and keep its localized label, description, and audioUrl tied to the same caller-provided item. An action without playable media has no audioUrl.

Map an MG reference style choice to one single field with variant:"visual". Use the reference ID as the option id, its short title as the label, and the selected detail's heroPreview.url as preview. Include one __other__ option labeled "其他" / "Other"; the tool supplies its text input. That branch accepts either a new preference or a request for another batch; do not add a separate Show more option. Return the selected reference ID to the MG skill; it owns application. Do not bind apply_preset directly to a reference ID.

Example field, replacing the reference placeholders with the fetched shortlist and localizing the labels:

{
  "id": "mg_style",
  "label": "选择 MG 风格",
  "type": "single",
  "variant": "visual",
  "options": [
    { "id": "REFERENCE_ID", "label": "TITLE", "preview": "HERO_PREVIEW_URL" },
    { "id": "__other__", "label": "其他" }
  ]
}

The Other answer returns to discovery, without applying a style or starting production. Keep the image-option IDs unchanged in the next step.

Map an AI-avatar identity choice to one single field with variant:"visual". Use the live identityId as the option id, the returned name as its label, previewVideoUrl as previewVideo, and previewImageUrl as preview. The image remains the poster and automatic fallback if video loading fails. Keep create_avatar as a label-only option. Selecting it returns that value to the workflow; it does not open ChatCut's native avatar dialog, so request the source attachment separately and use asset-import.

Do not call ask_followup_questions solely to display a playable_preview, because a passive preview is not a question. Use Codex's supported audio attachment/media rendering when available. If this host session has no safe runtime-URL audio renderer, say that the preview is available in the ChatCut project assets and continue with the caller's separate branch decision; do not print HTML, a bare URL, or a fake widget tag.

Map explicit_consent to a single-select field containing only one confirmation option. Use the caller's full confirmation copy as its label and do not preselect it. Mark every blocking field as required and verify every required answer after submission before continuing.

Claude Code

Follow the structured-input recipe in chatcut-plugin-basics-claude: use one visualize.show_widget Elicitation form, submit only through .elicit-submit, and wait for the user to send the filled prompt. Never call ChatCut's ask_followup_questions in Claude Code because that host does not render its MCP-App result.

Map explicit_consent to an unchecked checkbox using the caller's complete localized copy. Do not add a file chooser for audio_reference; request the conversation attachment outside the form and load asset-import after the user sends it.

For playable_single_choice, resolve bundled media keys through ${CLAUDE_PLUGIN_ROOT}/assets/widget-media/manifest.json; use a label-only card when a key is absent and never embed or process the original source URL. Keep the stable value in the label-to-id map rather than exposing it as the DOM audio key. Runtime media URLs are not in the bundled manifest: do not embed them in Elicitation HTML. Present them through the host's normal safe link/audio surface, then use a label-only confirmation control.

AI-avatar previews are runtime catalog media and are not bundled in the plugin manifest. Keep each authoritative identityId mapped to its returned name, use label-only selectable cards in Elicitation, and tell the user that live video previews are available in ChatCut's AI Avatars library. Never embed or print the provider preview URL. A create_avatar selection returns to the workflow and then follows the normal conversation-attachment plus asset-import path.

For MG reference choices, look up the exact reference ID in the same manifest (entries[referenceId], for example a mg-reference:style:… key). An image entry provides path; resolve it against the manifest's immutable baseUrl and show that image beside its short title in the Elicitation form. Keep reference IDs mapped to the displayed labels. Do not substitute a similarly named preset.

The manifest may not include newly added references yet. For missing entries, use label-only choices and say their image previews are available in ChatCut; do not invent CDN paths, download or republish media during the conversation, or embed the runtime S3 URL. Include a single label-only Other choice with a text input. A preference or request for another batch returns to discovery, not style application.
