+- Add quoted-message context pipeline for QQ `REFIDX_*`: parse quote indices from inbound events, cache inbound/outbound message summaries, and inject quote body into agent context.
+- Add persistent quote index store (`~/.openclaw/qqbot/data/ref-index.jsonl`) with in-memory cache + JSONL append, restart recovery, 7-day TTL eviction, and compact.
+- Add structured quote attachment summaries (image/voice/video/file, local path/url, voice transcript source) for better reply grounding.
+
+### Improved
+
+- Bot replies now attach quote reference to the user's current message when available, improving threaded conversation readability in QQ.

+### 新增
+
+- 新增 QQ `REFIDX_*` 引用消息上下文链路：从入站事件解析引用索引，缓存入站/出站消息摘要，并将引用内容注入 agent 上下文。
+- 新增引用索引持久化存储（`~/.openclaw/qqbot/data/ref-index.jsonl`）：采用内存缓存 + JSONL 追加写，支持重启恢复、7 天 TTL 淘汰与 compact 压缩。
+- 新增结构化引用附件摘要（图片/语音/视频/文件、local path/url、语音转录来源），提升引用回复语义完整性。
+
+### 改进
+
+- 机器人回复在可用时自动挂载对当前用户消息的引用，提升 QQ 会话串联可读性。

 > **Note:** This plugin serves as a **message channel** only — it relays messages between QQ and OpenClaw. Capabilities like image understanding, voice transcription, drawing, etc. depend on the **AI model** you configure and the **skills** installed in OpenClaw, not on this plugin itself.
 
+### 💬 Quoted Message Context (REFIDX)
+
+QQ quote events carry index keys (e.g. `REFIDX_xxx`) instead of full original message body. The plugin now resolves these indices from a local persistent store and injects quote context into AI input, so replies better understand “which message is being quoted”.
+
+- Inbound and outbound messages with `ref_idx` are automatically indexed.
+- Store path: `~/.openclaw/qqbot/data/ref-index.jsonl` (survives gateway restart).
+- Quote body may include text + media summary (image/voice/video/file).
+
 ### 🎙️ Voice Messages (STT)
 
 With STT configured, the plugin automatically transcribes voice messages to text before passing them to AI. The whole process is transparent to the user — sending voice feels as natural as sending text.

 > **说明：** 本插件仅作为**消息通道**，负责在 QQ 和 OpenClaw 之间传递消息。图片理解、语音转录、AI 画图等能力取决于你配置的 **AI 模型**以及在 OpenClaw 中安装的 **skill**，而非插件本身提供。
 
+### 💬 引用消息上下文（REFIDX）
+
+QQ 的引用事件通常只携带索引键（如 `REFIDX_xxx`），不直接返回原始消息全文。插件已支持从本地持久化索引中解析引用内容，并注入 AI 上下文，帮助模型更准确理解“用户引用的是哪条消息”。
+
+- 入站/出站消息中的 `ref_idx` 会自动建立索引。
+- 存储位置：`~/.openclaw/qqbot/data/ref-index.jsonl`（网关重启后仍可恢复）。
+- 引用内容支持文本 + 媒体摘要（图片/语音/视频/文件）。
+
 ### 🎙️ 语音消息（STT）
 
 配置 STT 后，插件会自动将语音转录为文字再交给 AI 处理。整个过程对用户完全透明——发语音就像发文字一样自然，AI 听得懂你在说什么。
