Implementation Reference
- src/tools/wait.ts:35-65 (handler)The main handler function for the browser_wait_for tool. It handles waiting for a specified time, for text to appear (visible), or for text to disappear (hidden) using Playwright locators on the current browser tab. It also generates corresponding code snippets.handle: async (context, params) => { if (!params.text && !params.textGone && !params.time) throw new Error('Either time, text or textGone must be provided'); const code: string[] = []; if (params.time) { code.push(`await new Promise(f => setTimeout(f, ${params.time!} * 1000));`); await new Promise(f => setTimeout(f, Math.min(10000, params.time! * 1000))); } const tab = context.currentTabOrDie(); const locator = params.text ? tab.page.getByText(params.text).first() : undefined; const goneLocator = params.textGone ? tab.page.getByText(params.textGone).first() : undefined; if (goneLocator) { code.push(`await page.getByText(${JSON.stringify(params.textGone)}).first().waitFor({ state: 'hidden' });`); await goneLocator.waitFor({ state: 'hidden' }); } if (locator) { code.push(`await page.getByText(${JSON.stringify(params.text)}).first().waitFor({ state: 'visible' });`); await locator.waitFor({ state: 'visible' }); } return { code, captureSnapshot, waitForNetwork: false, }; },
