description	Generate, validate, and interpret static A2UI v0.8 JSON for interactive UI surfaces. Use when an agent needs to call publish_a2ui, author A2UI messages, check whether generated A2UI JSON is valid, or handle normalized userAction replies from interactive UI callbacks.

A2UI Author

Use this skill to work with the static A2UI v0.8 subset supported by the current renderer.

Workflow

1. Author A2UI server messages, not raw channel card JSON.
2. Read references/protocol.md for message structure, supported components, bindings, and current renderer adaptations.
3. Use references/examples.md for compact examples.
4. Validate generated JSON with the bundled script. Resolve <skill-dir> to this skill directory before running the command:

node <skill-dir>/scripts/validate-a2ui.js --version v0_8 path/to/a2ui.messages.json

5. For user replies, reason from A2UI userAction events. Do not expose raw channel callback payloads to application logic or an LLM.

Static Content Rule

Generate only static A2UI server messages: dataModelUpdate, surfaceUpdate, beginRendering, and deleteSurface. Do not emit messages or components outside the supported static subset documented in this skill.
