2 human and 3 agent dimensions measured from the pages checked; remaining dimensions are not scored.
## Scores
| Measure | Score |
| --- | --- |
| Humans | 83/100 (2/4 dimensions) |
| Agents | 45/100 (3/6 dimensions) |

The human score is the mean of the measured human dimensions, the agent score the mean of the measured agent dimensions, and the Door Gap the difference between them.
## What the machine actually did
The scanner recorded successful observations for 5 of 13 checks, but could not ask whether the door opens for requests carrying the AI crawlers' names. It came up empty on 7 other checks too.
- 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 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
- ok      walk the way a visitor would, to a signup form or a product
## Top issues
1. **No MCP manifest was identified at the 3 standard paths checked.** (agent_aware_instrumentation)
2. **No valid security.txt was identified at /.well-known/security.txt.** (machine_fetchable_trust)
3. **No valid llms.txt was identified at the site root.** (machine_discoverability)

## Files generated from this scan
- **Let verified assistants through** at `notes`, 1 hour, developer. Verify: The next scan opens the homepage and the key pages in a real browser and under the search crawler names, and every one is served.
- **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/churnzero-e6c53r
## The agent door
- **machine_discoverability** 75/100. Robots.txt names 1 AI crawlers and allows them. a real browser is served the page normally. our client was refused when declaring 5 AI crawlers that robots.txt welcomes. a sitemap listing 590 URLs. 11 schema.org types on the homepage.
- **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 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** 80/100. A signup form was reached in 2 steps from the homepage.
- **required_fields** 85/100. 1 of 2 fields on the observed form are marked required.
- **verification_walls** not measured. Not measured: this scan did not reach the page or action needed to verify it.
