Новые протоколы

Обнаружено 1 из 3

Well-known эндпоинты, которые ищут ИИ-агенты. Обнаружено — значит агент может автоматически найти и подключиться к вашему сервису.

  • OAuth Discovery RFC 8414
    /.well-known/oauth-authorization-server
  • MCP Server Card Anthropic
    /.well-known/mcp.json
    • name: Resend
    • 12 tool(s)
  • A2A Agent Card Google
    /.well-known/agent.json

Ваша страница не использует элементы <article> или <main>. Эти семантические контейнеры помогают ИИ-агентам определить основную область контента и игнорировать навигацию, боковые панели и подвал.

Как внедрить

Добавьте элемент <main> вокруг основного контента вашей страницы и используйте <article> для самостоятельных блоков контента, таких как записи блога или описания товаров.

На вашей странице низкое соотношение фактического контента к общему HTML. Большая часть веса страницы приходится на разметку, скрипты или стили, а не на контент.

Как внедрить

Перенесите CSS во внешние таблицы стилей, удалите inline-стили, минимизируйте JavaScript и убедитесь, что HTML сфокусирован на структуре контента.

Многие элементы имеют атрибуты style. Они создают шум для ИИ-агентов при извлечении контента.

Как внедрить

Перенесите все inline-стили в CSS-классы в вашей таблице стилей. Используйте утилитарные CSS-фреймворки, такие как Tailwind, если вам нужно много уникальных стилей.

Ваш сайт не поддерживает Markdown for Agents. Этот стандарт Cloudflare позволяет ИИ-агентам запрашивать контент в формате markdown, сокращая использование токенов на ~80%.

Как внедрить

Реализуйте одно или несколько: (1) Отвечать на Accept: text/markdown контентом в формате markdown. (2) Обслуживать URL с .md (например, /page.md). (3) Добавить теги <link rel="alternate" type="text/markdown">. (4) Добавить HTTP-заголовки Link для обнаружения markdown.

{\n res.setHeader('Vary', 'Accept');\n res.setHeader('Link', '; rel=\"alternate\"; type=\"text/markdown\"');\n if ((req.headers.accept || '').includes('text/markdown')) {\n res.type('text/markdown; charset=utf-8');\n return res.send(renderMarkdown('page'));\n }\n res.render('page');\n});"},{"id":"fastify","label":"Fastify","language":"javascript","filename":"server.js","code":"// Mechanisms 1 + 4: content negotiation + Link header\nfastify.get('/page', async (req, reply) => {\n reply.header('Vary', 'Accept');\n reply.header('Link', '; rel=\"alternate\"; type=\"text/markdown\"');\n if ((req.headers.accept || '').includes('text/markdown')) {\n return reply.type('text/markdown; charset=utf-8').send(renderMarkdown('page'));\n }\n return reply.view('/page.ejs');\n});"},{"id":"nextjs","label":"Next.js","language":"typescript","filename":"app/page/route.ts","code":"// Next.js App Router — Route Handler returning Markdown\nimport { NextRequest } from 'next/server';\nimport { renderMarkdown } from '@/lib/md';\nexport async function GET(req: NextRequest) {\n const accept = req.headers.get('accept') || '';\n if (accept.includes('text/markdown')) {\n return new Response(await renderMarkdown('page'), {\n headers: {\n 'Content-Type': 'text/markdown; charset=utf-8',\n 'Vary': 'Accept',\n },\n });\n }\n // Fall through to the page component\n return new Response(null, { status: 404 });\n}"},{"id":"wordpress","label":"WordPress","language":"php","filename":"functions.php","code":"post_content));\n exit;\n});"},{"id":"static","label":"Hugo / Jekyll / Astro","language":"txt","filename":"static/page.md","code":"# Mechanism 2: serve .md alongside .html\n# Hugo: place page.md in /static/ — built unchanged\n# Jekyll: drop page.md in /assets/ — copied as-is\n# Astro: src/pages/page.md.ts that exports a GET returning markdown\n\n# Then advertise with mechanism 3 in :\n# "}] }'>

Ваша страница в значительной степени полагается на элементы <div>. Семантические элементы, такие как <section>, <nav>, <header>, <footer> и <aside>, обеспечивают осмысленную структуру для ИИ-агентов.

Как внедрить

Замените общие контейнеры <div> подходящими семантическими элементами. Используйте <section> для тематических групп, <nav> для навигации, <header>/<footer> для верхних и нижних колонтитулов страниц и разделов.

Структура заголовков вашей страницы имеет проблемы (пропущенные уровни или несколько тегов h1). Чёткая иерархия помогает ИИ-агентам понять организацию контента.

Как внедрить

Убедитесь, что на странице ровно один <h1>, а заголовки следуют последовательному порядку: h1 > h2 > h3. Не пропускайте уровни (например, h1 сразу к h3).
