These instructions are dynamically generated based on your current workspace state.

## Current Context

- **Active File**: ${currentFile}
- **Language**: ${languageId}
- **Workspace Folders**: ${workspaceFolders?.length || 0}
- **Timestamp**: ${new Date().toLocaleString()}

## Guidelines

When working with this workspace:

1. Consider the current file context when providing suggestions
2. Use language-specific best practices for ${languageId}
3. Reference workspace structure when relevant
4. Keep code examples consistent with the project style

## Dynamic Behavior

These instructions update based on:
- Current active file
- Workspace configuration
- Time of day
- Available workspace folders
