Prompt — paste into your agentPrompt —— 直接粘贴给你的代理
Build a streaming AI response surface that appends readable chunks into a real article, shows a subtle active marker while generation is running, and exposes Stop, Retry, and Copy actions at the right states. Use AbortController for cancellation, keep the partial answer after Stop or Error, announce meaningful milestones politely, and never replace content with an endless typing animation.
构建一个流式 AI 响应区域，把可读的分段内容追加到真实文章中；生成时显示克制的活动标记，并在恰当状态提供停止、重试和复制。用 AbortController 取消请求；停止或出错后保留已生成内容；礼貌地播报重要节点；不要用无限打字动画伪造活动。
Debug prompt — when it misbehaves调试 Prompt —— 当它不听话时
Debug my streaming response. Check that chunks append in order without duplicating text; Stop actually aborts the request and clears the busy state; a network error preserves partial content and exposes Retry; aria-live is not announcing every token; the caret disappears when complete; Copy returns plain text; and the response does not cause horizontal overflow. The symptom:
调试我的流式响应。检查分段是否按顺序追加且不重复；停止操作是否真的中止请求并清除忙碌状态；网络错误是否保留部分内容并提供重试；aria-live 是否逐 token 播报；完成后光标是否消失；复制是否返回纯文本；响应是否造成横向溢出。症状：
In code代码里叫什么
| Framework框架 | Symbol符号 | Note说明 |
|---|---|---|
| HTML | aria-live="polite" | announce completed chunks without making every token noisy |
| Web API | ReadableStream | consume chunks and handle abort/error events |
| Web API | AbortController | let users stop an in-flight generation |
| CSS | white-space + caret | keep partial text readable without layout jumps |
