Configure custom agent for DB Viewer extension development

[Copilot]

Populated the custom agent template with project-specific context and development guidelines for the DB Viewer VS Code extension.

Changes

• Agent configuration (.github/agents/my-agent.agent.md)
  • Agent name: db-viewer-expert
  • Description: Expert agent for SQLite database viewer extension
  • Architecture overview: Custom editor provider, webview UI, sql.js integration
  • Development workflow: Build commands, linting, testing, deployment
  • Code patterns: TypeScript conventions, example implementations
  • Constraints: Version compatibility, security (SQL injection prevention), bundle size
  • Common tasks: Adding file types, features, bug fixes

The agent provides context on the TypeScript/VS Code Extension API stack, esbuild build system, and project-specific patterns like the CustomReadonlyEditorProvider implementation.

Example

// Pattern documented in agent configuration
export class DbViewerProvider implements vscode.CustomReadonlyEditorProvider {
    public static register(context: vscode.ExtensionContext): vscode.Disposable {
        const provider = new DbViewerProvider(context);
        return vscode.window.registerCustomEditorProvider(
            DbViewerProvider.viewType,
            provider,
            { webviewOptions: { retainContextWhenHidden: true } }
        );
    }
}
