 ## Unreleased
 
+- Shell: Fix slash command completion menu not appearing on exact match — typing a full command name like `/editor` now still shows the command entry (with its description) in the completion menu, while still suppressing unrelated prefix noise such as `/mcp` expanding to `/mcp-server` (fixes #1752)
 - Shell: Add `/btw` side question command — ask a quick question during streaming without interrupting the main conversation; uses the same system prompt and tool definitions for prompt cache alignment; responses display in a scrollable modal panel with streaming support
 - Shell: Redesign bottom dynamic area — split the monolithic `visualize.py` (1865 lines) into a modular package (`visualize/`) with dedicated modules for input routing, interactive prompts, approval/question panels, and btw modal; unify input semantics with `classify_input()` for consistent command routing
 - Shell: Add queue and steer dual-channel input during streaming — Enter queues messages for delivery after the current turn; Ctrl+S injects messages immediately into the running turn's context; queued messages display in the prompt area with count indicator and can be recalled with ↑

 ## 未发布
 
+- Shell：修复 Slash 命令完全匹配时补全菜单不再弹出的问题——输入 `/editor` 等完整命令名时,补全菜单会继续显示该命令条目(含描述),同时仍然抑制诸如 `/mcp` → `/mcp-server` 这类无关前缀噪音(修复 #1752)
 - Shell：新增 `/btw` 侧问命令——在 streaming 期间提出快速问题，不打断主对话；使用相同的系统提示词和工具定义以对齐 Prompt 缓存；响应在可滚动的模态面板中显示，支持流式输出
 - Shell：重新设计底部动态区——将单体 `visualize.py`（1865 行）拆分为模块化包（`visualize/`），包含输入路由、交互式提示、审批/提问面板和 btw 模态面板等独立模块；通过 `classify_input()` 统一输入语义，实现一致的命令路由
 - Shell：新增 streaming 期间的排队和 steer 双通道输入——Enter 将消息排队，在当前轮次结束后发送；Ctrl+S 将消息立即注入到正在运行的轮次上下文中；排队消息在提示区域显示计数指示器，可通过 ↑ 键召回编辑
