Halcyon I is hard for agents to use.
AI assistants cannot open the website of Halcyon I, so they rely on what other sites say about it.

## What to fix first

- **The site turns every visitor without a browser away, AI agents included.** (+25 points) A plain fetch was refused (cloudflare_challenge); only a real browser got the page. Every AI crawler and agent is turned away the same way, so Reachable scores 0 and the rest is measured on the rendered page. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **No tickets and prices found.** (+7 points) Agents answer 'what does it cost and when' from marketplaces instead. Add a page with tickets, times and prices as text and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **Structured data is incomplete.** (+3 points) Missing: opening hours. Guide: https://directindex.org/guides/structured-data-restaurant

## Fix kit: What to paste

Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong.

<script type="application/ld+json">

        "name": "Reservation"
      }
    }
  ]
}
</script>
```

## Already right
- **robots.txt lets AI crawlers in.** There is no robots.txt, which allows everything.
- **Structured data present (LocalBusiness).** address, phone
- **Tickets on your own site.** Agents can buy tickets without a marketplace in the loop.
