Summary

The VSCode IDE Companion extension currently does not provide a way to enable experimental features like Agent Skills (--experimental-skills) or other CLI flags. Users should be able to configure these options through extension settings.

Background

The Qwen Code CLI supports several experimental features that can be enabled via command-line arguments:

• --experimental-skills - Enables the Agent Skills feature
• --proxy <url> - Configure proxy for network requests
• Other potential flags for future experimental features

Currently, in qwenConnectionHandler.ts, the extraArgs array is hardcoded as empty:

```typescript
// Build extra CLI arguments (only essential parameters)
const extraArgs: string[] = [];

await connection.connect(cliEntryPath!, workingDir, extraArgs);
```

This means users cannot enable experimental features like Skills when using the VSCode extension.

Expected Behavior

Users should be able to configure experimental CLI flags through:

1. VSCode Extension Settings - Add a configuration option in package.json contributes section, e.g.:
   ```json
   {
   "qwen-code.experimental.skills": {
   "type": "boolean",
   "default": false,
   "description": "Enable experimental Agent Skills feature"
   },
   "qwen-code.cli.extraArgs": {
   "type": "array",
   "default": [],
   "description": "Additional CLI arguments to pass to Qwen Code"
   }
   }
   ```

2. Read settings and pass to CLI - Update qwenConnectionHandler.ts to read these settings and include them in extraArgs.

Proposed Implementation

1. Add configuration options to the extension's package.json

2. Update qwenConnectionHandler.ts to read settings:
   ```typescript
   const config = vscode.workspace.getConfiguration('qwen-code');
   const extraArgs: string[] = [];

   if (config.get('experimental.skills')) {
   extraArgs.push('--experimental-skills');
   }

   const customArgs = config.get<string[]>('cli.extraArgs') || [];
   extraArgs.push(...customArgs);
   ```
