Implementation Reference
- src/tools.ts:628-648 (handler)Implements the core logic for the 'browser_go_back' tool by retrieving the browser instance and calling page.goBack(). Handles errors and returns ToolResult.private async goBack(instanceId: string): Promise<ToolResult> { const instance = this.browserManager.getInstance(instanceId); if (!instance) { return { success: false, error: `Instance ${instanceId} not found` }; } try { await instance.page.goBack(); return { success: true, data: { url: instance.page.url() }, instanceId }; } catch (error) { return { success: false, error: `Go back failed: ${error instanceof Error ? error.message : error}`, instanceId }; } }
- src/tools.ts:123-135 (schema)Defines the tool schema including name, description, and input schema requiring 'instanceId'.name: 'browser_go_back', description: 'Go back to the previous page', inputSchema: { type: 'object', properties: { instanceId: { type: 'string', description: 'Instance ID' } }, required: ['instanceId'] } },
- src/tools.ts:524-526 (registration)Registers the tool handler in the executeTools switch statement, dispatching to the goBack method.case 'browser_go_back': return await this.goBack(args.instanceId);
