Implementation Reference

• src/tools/page.ts:137-159 (handler)

  The implementation of the pilot_page_css tool handler, which uses Playwright's locator to evaluate and retrieve the computed CSS property of a specified element.

  server.tool(
    'pilot_page_css',
    'Get computed CSS property value for an element.',
    {
      ref: z.string().describe('Element ref or CSS selector'),
      property: z.string().describe('CSS property name (e.g. color, font-size)'),
    },
    async ({ ref, property }) => {
      await bm.ensureBrowser();
      try {
        const page = bm.getPage();
        const resolved = await bm.resolveRef(ref);
        const locator = 'locator' in resolved ? resolved.locator : page.locator(resolved.selector);
        const value = await locator.evaluate(
          (el, prop) => getComputedStyle(el).getPropertyValue(prop),
          property
        );
        return { content: [{ type: 'text' as const, text: value }] };
      } catch (err) {
        return { content: [{ type: 'text' as const, text: wrapError(err) }], isError: true };
      }
    }
  );
