• src/tools/browser/interaction.ts:114-125 (handler)

  The SelectTool.execute method implements the core logic of the 'playwright_select' tool, waiting for the selector and calling page.selectOption.
  export class SelectTool extends BrowserToolBase { /** * Execute the select tool */ async execute(args: any, context: ToolContext): Promise<ToolResponse> { return this.safeExecute(context, async (page) => { await page.waitForSelector(args.selector); await page.selectOption(args.selector, args.value); return createSuccessResponse(`Selected ${args.selector} with: ${args.value}`); }); } }
• src/tools.ts:171-182 (schema)

  The input schema definition for the 'playwright_select' tool, defining required selector and value parameters.
  { name: "playwright_select", description: "Select an element on the page with Select tag", inputSchema: { type: "object", properties: { selector: { type: "string", description: "CSS selector for element to select" }, value: { type: "string", description: "Value to select" }, }, required: ["selector", "value"], }, },
• src/toolHandler.ts:597-598 (registration)

  Registration and dispatch of the 'playwright_select' tool in the main tool handler switch statement, calling the SelectTool's execute method.

• src/toolHandler.ts:396-396 (registration)

  Instantiation of the SelectTool instance used for handling 'playwright_select' tool calls.
