Implementation Reference

• src/tools/page.ts:96-113 (handler)

  Creates the 'page_waitTimeout' tool, including its handler (execute function) that parses arguments, acquires the page via manager, and calls page.waitFor(milliseconds) to wait the specified time.

  function createWaitForTimeoutTool(manager: WeappAutomatorManager): AnyTool {
    return {
      name: "page_waitTimeout",
      description: "等待指定的毫秒数。",
      parameters: waitForTimeoutParameters,
      execute: async (rawArgs, context: ToolContext) => {
        const args = waitForTimeoutParameters.parse(rawArgs ?? {});
        return manager.withPage<ContentResult>(
          context.log,
          { overrides: args.connection },
          async (page) => {
            await page.waitFor(args.milliseconds);
            return toTextResult(`已等待 ${args.milliseconds}ms。`);
          }
        );
      },
    };
  }

• src/tools/page.ts:33-35 (schema)

  Zod schema defining the input parameters for the 'page_waitTimeout' tool: milliseconds as a non-negative integer.

  const waitForTimeoutParameters = connectionContainerSchema.extend({
    milliseconds: z.coerce.number().int().nonnegative(),
  });

• src/tools/page.ts:42-50 (registration)

  Registers the 'page_waitTimeout' tool (via createWaitForTimeoutTool(manager)) in the array of page tools returned by createPageTools.

  export function createPageTools(manager: WeappAutomatorManager): AnyTool[] {
    return [
      createGetElementTool(manager),
      createWaitForElementTool(manager),
      createWaitForTimeoutTool(manager),
      createGetPageDataTool(manager),
      createSetPageDataTool(manager),
      createCallPageMethodTool(manager),
    ];
