Implementation Reference
- src/tools/wait.ts:35-62 (handler)The handler function that implements the logic for the 'browser_wait_for' tool. It handles waiting for a specified time, text to appear (visible), or text to disappear (hidden) using Playwright locators on the current browser tab.
handle: async (context, params, response) => { 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, ${params.time!} * 1000));`); await new Promise(f => setTimeout(f, Math.min(30000, params.time! * 1000))); } const tab = context.currentTabOrDie(); const locator = params.text ? tab.page.getByText(params.text).first() : undefined; const goneLocator = params.textGone ? tab.page.getByText(params.textGone).first() : undefined; if (goneLocator) { code.push(`await page.getByText(${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' }); } response.addResult(`Waited for ${params.text || params.textGone || params.time}`); response.setIncludeSnapshot(); }, - src/tools/wait.ts:23-33 (schema)The schema definition for the 'browser_wait_for' tool, including name, title, description, and Zod input schema for parameters: time, text, textGone.
