Agent door only. The human door could not be measured on this scan. A Door Gap needs both doors, so this scan does not report one.
## What the machine actually did
The scanner recorded successful observations for 3 of 12 checks, but could not ask whether the door opens for requests carrying the AI crawlers' names. It came up empty on 8 other checks too. 1 check could not be measured; see the report limitations.
- ok      reach the site at all
- ok      find out whether machines are welcome
- missing ask whether the door opens for requests carrying the AI crawlers' names
- missing read the site's own guide for language models
- ok      find out what pages exist
- missing find a contact route for machines
- missing find an MCP manifest at the standard paths checked
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- missing read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
## What a visitor meets
1. **Entry observation** (unmeasured). The homepage was read, but no supported destination for marketplace offerings was identified in the visible links checked.
## Top issues
1. **No valid security.txt was identified at /.well-known/security.txt.** (machine_fetchable_trust)
2. **No valid llms.txt was identified at the site root.** (machine_discoverability)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/levels-nsc8e2
## Files generated from this scan
- **Let verified assistants through** at `notes`, 1 hour, developer. Verify: On a subsequent scan, compare the same endpoint and client response. An unavailable check remains unresolved.
- **Organization structured data** at `homepage`, 15 minutes, developer. Verify: The next scan reads Organization and WebSite nodes in the homepage JSON-LD and the structured data check passes.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt check passes.
- **llms.txt** at `/llms.txt`, 15 minutes, no developer needed. Verify: The next scan fetches /llms.txt as text and the llms.txt check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/levels-nsc8e2
## The agent door
- **machine_discoverability** 53/100. Robots.txt explicitly names 5 AI crawler tokens; policies differ by token. On its first visit, our browser read the homepage. Our client was refused when declaring 2 AI crawlers that robots.txt welcomes. A sitemap listing 1285 URLs.
- **programmatic_onboarding** not measured. Not applicable to this scanned surface.
- **pricing_legibility** not measured. Not applicable to this scanned surface.
- **agent_aware_instrumentation** 20/100. No MCP manifest was identified at the discovery paths checked. Robots.txt explicitly names 5 AI crawler tokens; policies differ by token.
- **machine_fetchable_trust** 40/100. No security.txt was identified at the checked path. The homepage answers automated requests.
- **commercial_rails** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
## The human door
- **steps_to_first_value** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **required_fields** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **verification_walls** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **error_recovery** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
