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 7 of 13 checks, but could not read the site's own guide for language models. It came up empty on 5 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
- ok      read the developer documentation
- ok      read the prices without running JavaScript
## What a visitor meets
1. **Entry observation** (observed). Reached the linked “Contact us” page. No form was submitted, payment made or account created; this route has no applicable signup or checkout score.
## 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/plausible-cbt9sy
## Files generated from this scan
- **robots.txt rules for AI crawlers** at `/robots.txt`, 10 minutes, no developer needed. Verify: The next scan reads robots.txt and finds every search and agent crawler allowed, none of them kept off product or pricing paths.
- **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.
- **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/plausible-cbt9sy
## The agent door
- **machine_discoverability** 77/100. No restriction on the tested crawler names was found in robots.txt. on its first visit, our browser read the homepage. no user agent rule refused the tested retrieval crawler names. a sitemap listing 160 URLs.
- **programmatic_onboarding** 46/100. API credentials are documented. authentication is documented. code samples are provided. OAuth authorization metadata is published.
- **pricing_legibility** 10/100. 3 price-like amounts were identified in the homepage HTML; no product page was read.
- **agent_aware_instrumentation** 30/100. No MCP manifest was identified at the discovery paths checked. OAuth authorization-server metadata is published; this alone does not identify an MCP endpoint. developer documentation describes an API, but only in prose.
- **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 applicable to this scanned surface.
- **required_fields** not measured. Not applicable to this scanned surface.
- **verification_walls** not measured. Not applicable to this scanned surface.
- **error_recovery** not measured. Not applicable to this scanned surface.
