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 6 of 12 checks, but could not read the site's own guide for language models. It came up empty on 5 other checks too. 3 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
- missing find out what pages exist
- ok      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
- ok      read the developer documentation
- ok      read the prices without running JavaScript
## What a visitor meets
1. **Entry observation** (unmeasured). Primary entry is "Sign Up". 2 steps from the homepage. no signup form or sign-in options were identified on the rendered page; the signup requirements remain unmeasured.
## Top issues
1. **No valid llms.txt was identified at the site root.** (machine_discoverability)
   - Evidence: /llms.txt: not found (404)
   - Evidence: Checked URL: https://healthchecks.io/llms.txt
   - Fix: Publish /llms.txt: a short markdown index of the pages an assistant should read first.

## 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.
- **pricing.md** at `/pricing.md`, 20 minutes, no developer needed. Verify: The next scan fetches /pricing.md as text and records pricing as machine readable.
- **sitemap.xml** at `/sitemap.xml`, 20 minutes, no developer needed. Verify: The next scan fetches /sitemap.xml, finds a urlset, and the sitemap check passes.
- **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.
- **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/healthchecks-8t4zzu
## The agent door
- **machine_discoverability** 70/100. 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.
- **programmatic_onboarding** not measured. Not measured: robots.txt did not permit our scanner to read the required page.
- **pricing_legibility** 85/100. 8 prices are readable without JavaScript, with no tier sent to sales.
- **agent_aware_instrumentation** 18/100. No MCP manifest was identified at the discovery paths checked. Developer documentation describes an API, but only in prose.
- **machine_fetchable_trust** 85/100. Security.txt is published with a contact route. 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.
