 # Change Log
 
-## [0.2.5] - 2026-07-14
+## [0.2.6] - 2026-07-14
 
 ### Added
 
-- Default keybinding `Ctrl+K C` / `Cmd+K C` for all 4 copy commands (context-aware)
+- CodeAction (💡 灯泡): 划选文本后灯泡亮起，快速执行「Copy to AI: 选中区域」
+- 快捷键 `Shift+Alt+C` / `Shift+Option+C`: 编辑器/资源管理器上下文感知
+- 快捷键键盘触发时自动降级到当前编辑器文件
+
+## [0.2.5] - 2026-07-14
+
+### Changed
+
+- 快捷键从 `Ctrl+K C` 改为 `Shift+Alt+C`（`Shift+Option+C`），避免与内置快捷键冲突
 
 ## [0.2.3] - 2026-07-11

+# Copy AI Ctx 选中悬浮按钮 — 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：** 编辑器中划选文本后，通过 CodeAction（💡 灯泡）快速触发"复制选中区域"操作。
+
+**架构：** 新增 `codeActionProvider.ts` 文件实现 CodeActionProvider，在 `extension.ts` 中注册。复用已有的 `copySelection` 命令。
+
+**技术栈：** VS Code Extension API — `languages.registerCodeActionsProvider`、`CodeAction`、`CodeActionKind.Source`
+
+---
+
+### 任务 1：创建 CodeActionProvider
+
+**文件：**
+- 创建：`src/codeActionProvider.ts`
+
+- [ ] **步骤 1：编写 `codeActionProvider.ts`**
+
+```typescript
+import * as vscode from 'vscode';
+
+export class CopyAiCodeActionProvider implements vscode.CodeActionProvider {
+  public static readonly providedCodeActionKinds = [
+    vscode.CodeActionKind.Source,
+  ];
+
+  provideCodeActions(
+    document: vscode.TextDocument,
+    range: vscode.Range | vscode.Selection,
+  ): vscode.ProviderResult<vscode.CodeAction[]> {
+    // Only provide action when there's a selection
+    if (range.isEmpty) return;
+
+    const action = new vscode.CodeAction(
+      '$(clippy) Copy to AI: 选中区域',
+      vscode.CodeActionKind.Source,
+    );
+    action.command = {
+      command: 'copy-ai-ctx.copySelection',
+      title: 'Copy to AI: 选中区域',
+    };
+    return [action];
+  }
+}
+```
+
+- [ ] **步骤 2：修改 `extension.ts` 注册 Provider**
+
+在 `activate` 函数中，导入并注册 CodeActionProvider：
+
+```typescript
+import { CopyAiCodeActionProvider } from './codeActionProvider';
+
+// 在 activate 函数末尾，console.log('[copy-ai-ctx] activated'); 之前添加：
+context.subscriptions.push(
+  vscode.languages.registerCodeActionsProvider(
+    { pattern: '**' },
+    new CopyAiCodeActionProvider(),
+    {
+      providedCodeActionKinds:
+        CopyAiCodeActionProvider.providedCodeActionKinds,
+    },
+  ),
+);
+```
+
+- [ ] **步骤 3：运行 build 验证**
+
+运行：`npm run build`
+预期：esbuild 打包成功，无报错退出。
+
+- [ ] **步骤 4：Commit**
+
+```bash
+git add src/codeActionProvider.ts src/extension.ts
+git commit -m "feat: add CodeAction (lightbulb) for copy selection on text selection"
+```
+
+### 任务 2：重新打包
+
+**文件：**
+- 修改：`package.json`（bump version）
+
+- [ ] **步骤 1：打包 vsix**
+
+```bash
+npm run package
+```
+
+- [ ] **步骤 2：Commit**
+
+```bash
+git add CHANGELOG.md package.json
+git commit -m "chore: bump version for CodeAction feature"
+```
