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 5 of 12 checks, but could not read the site's own guide for language models. It came up empty on 6 other checks too. 1 checks could not be measured; see the report limitations.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      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 a published agent interface
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- ok      read the homepage as data rather than as a page
- missing find a machine readable API spec
- missing read the developer documentation
## Top issues
1. **No OpenAPI specification was identified at the 6 standard paths checked.** (programmatic_onboarding)
2. **No MCP manifest was identified at the 3 standard paths checked.** (agent_aware_instrumentation)
3. **No valid security.txt was identified at /.well-known/security.txt.** (machine_fetchable_trust)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/404media-jgds7q
## Files generated from this scan
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that 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/404media-jgds7q
## The agent door
- **machine_discoverability** 86/100. Robots.txt blocks 1 training crawler, a choice about model weights rather than about buyers. on its first visit, our browser read the homepage. no user agent rule refused the tested retrieval crawler names. a sitemap listing 516 URLs.
- **programmatic_onboarding** 10/100. No API interface was identified through the discovery paths and homepage links checked.
- **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 names 1 AI crawlers and allows them.
- **machine_fetchable_trust** 40/100. No security.txt was identified at the checked path. the homepage answers automated requests.
- **commercial_rails** not measured. Not applicable to this scanned surface.
## The human door
- **steps_to_first_value** not measured. Not measured: an access refusal or challenge prevented our scanner from reading the required page.
- **required_fields** not measured. Not measured: an access refusal or challenge prevented our scanner from reading the required page.
- **verification_walls** not measured. Not measured: an access refusal or challenge prevented our scanner from reading the required page.
- **error_recovery** not measured. Not measured: an access refusal or challenge prevented our scanner from reading the required page.
