+# Copy AI Ctx 快捷键支持 — 实现计划
+
+> **面向 AI 代理的工作者：** 必需子技能：使用 superpowers:subagent-driven-development（推荐）或 superpowers:executing-plans 逐任务实现此计划。步骤使用复选框（`- [ ]`）语法来跟踪进度。
+
+**目标：** 为 Copy AI Ctx 扩展的 4 个命令添加 `Ctrl+K C`（macOS: `Cmd+K C`）快捷键支持。
+
+**架构：** 仅在 `package.json` 的 `contributes` 下新增 `keybindings` 数组，通过 VS Code `when` 条件自动匹配上下文（编辑器选中/未选中、资源管理器单选/多选），无需修改 TypeScript 代码。
+
+**技术栈：** VS Code extension manifest（`package.json`）
+
+---
+
+### 任务 1：在 package.json 中添加 keybindings 配置
+
+**文件：**
+- 修改：`package.json`
+
+- [ ] **步骤 1：在 contributes 中新增 keybindings 数组**
+
+在 `package.json` 的 `contributes` 对象中，在 `menus` 同级新增 `keybindings` 数组：
+
+```jsonc
+"keybindings": [
+  {
+    "key": "ctrl+k ctrl+c",
+    "command": "copy-ai-ctx.copySelection",
+    "when": "editorHasSelection"
+  },
+  {
+    "key": "ctrl+k ctrl+c",
+    "command": "copy-ai-ctx.copyFile",
+    "when": "!editorHasSelection && editorFocus"
+  },
+  {
+    "key": "ctrl+k ctrl+c",
+    "command": "copy-ai-ctx.copySelectedFiles",
+    "when": "explorerViewletVisible && !listMultiSelection"
+  },
+  {
+    "key": "ctrl+k ctrl+c",
+    "command": "copy-ai-ctx.copyMultiFiles",
+    "when": "explorerViewletVisible && listMultiSelection"
+  }
+]
+```
+
+- [ ] **步骤 2：运行 build 验证配置无语法错误**
+
+运行：`npm run build`
+
+预期：esbuild 打包成功，无报错退出。
+
+- [ ] **步骤 3：Commit**
+
+```bash
+git add package.json
+git commit -m "feat: add Ctrl+K C keybinding for all 4 commands"
+```
