Implementation Reference
- src/tools/common.ts:54-72 (handler)The handler function for the 'browser_resize' tool. It resizes the viewport size of the current browser tab using the provided width and height parameters, generates a code snippet representing the action, defines an action to execute the resize, and returns the necessary metadata for execution.handle: async (context, params) => { const tab = context.currentTabOrDie(); const code = [ `// Resize browser window to ${params.width}x${params.height}`, `await page.setViewportSize({ width: ${params.width}, height: ${params.height} });` ]; const action = async () => { await tab.page.setViewportSize({ width: params.width, height: params.height }); }; return { code, action, captureSnapshot, waitForNetwork: true }; },
- src/tools/common.ts:43-52 (schema)The schema definition for the 'browser_resize' tool, including name, title, description, input schema validating width and height as numbers, and type as readOnly.schema: { name: 'browser_resize', title: 'Resize browser window', description: 'Resize the browser window', inputSchema: z.object({ width: z.number().describe('Width of the browser window'), height: z.number().describe('Height of the browser window'), }), type: 'readOnly', },

- src/tools.ts:52-66 (registration)Registration of the browser_resize tool as part of the visionTools array, imported via common(false) which includes the resize tool.export const visionTools: Tool<any>[] = [ ...common(false), ...console, ...dialogs(false), ...files(false), ...install, ...keyboard(false), ...navigate(false), ...network, ...pdf, ...tabs(false), ...testing, ...vision, ...wait(false), ];
