The search revealed that adding new website entries to the llms.txt hub is an ongoing pattern of work. Recent related issues include:

Key Observations for Your Review

1. Consistent workflow: The project follows a clear pattern of adding individual website listings with standardized metadata (name, description, website URL, llms.txt URL, category, publication date).

2. External submissions: The PR notes it was created via admin token for a user without direct repository access, which aligns with this being a community-contributed submission to the hub.

3. Verification checklist: Since this follows the established pattern, your review should verify:

   • The website (https://ceis-it.de/) has a valid llms.txt file accessible at https://ceis-it.de/llms.txt
   • The MDX front matter metadata is correctly formatted and complete
   • The category classification ("other") is appropriate for this submission

1-9: Verify that the referenced URLs are accessible before merging.

Please ensure that both the website and llms.txt file are accessible and properly formatted:

1. Website URL (line 4): https://ceis-it.de/ — confirm it's responsive and contains the described IT services.
2. llmsUrl (line 5): https://ceis-it.de/llms.txt — verify this file exists and is accessible at the root of the domain, following the llms.txt standard which proposes adding a /llms.txt markdown file to websites to provide LLM-friendly content.
3. llmsFullUrl (line 6): This field is left empty. Clarify whether this is intentional (e.g., when a full-text version doesn't exist) or if it should be populated.

---

2-8: Verify metadata format consistency with other entries.

The front matter metadata (lines 2–8) uses a consistent structure. Please confirm that:

• The date format (publishedAt: '2026-01-05') matches the ISO 8601 format used in other entries.
• The category classification 'other' is appropriate for an IT service/computer repair shop, or if a more specific category (e.g., 'service', 'technology') should be used.

---

11-13: Content duplication between front matter and body.

The description in the front matter (line 3) is identical to the body content (line 13). While this may be intentional, verify that this pattern is consistent with other website entries in the hub. If descriptions vary, consider whether the body should provide additional context or differentiation.
