Only 1,863 characters of your documentation survive without JavaScript, and that is the version an agent reads.

https://docs.sentry.io/platforms/apple/data-management/ served 1,863 characters of text to a plain fetch. The check passes at 2,000, which is about one screen of prose.

This is the whole list: everything we could measure and you do not pass. Another 2 points sit behind checks we could not evaluate on your domain, and each of those lines below says what would make it measurable.

1
Programmatic key provisioningan afternoon · +2
Document how a key is created without opening a dashboard: management API, service account or CLI. If no such path exists, that gap is the finding, not the docs.
2
Agent entry pointan afternoon · +1
The file is there and it states a policy rather than a procedure. It counts when it names a credential, an endpoint or a way to get an account: the path from nothing to a working key, in steps. Ours is at /agent-signup.md and it is 1.7 kB.
3
No CAPTCHA in the signup HTMLan afternoon · +1
Trigger recaptcha on a risk signal instead of on every signup, or open an API path to an account. A CAPTCHA is a hard stop, not a speed bump.

None of this tells you whether an agent picked you

Everything above is a file an agent could read. Whether one actually chose you is a different measurement, and we have not run it on sentry.io. What we have run it on is a rich text editor vendor: six agents, one brief, six isolated copies of a real codebase. All six picked the same competitor, and the vendor being studied was never named, not even on a rejection list, while the runs named and dismissed ten alternatives between them. In an earlier round, run before we isolated the copies, it was named twice and struck off both times in four words: Fully commercial, licence key required. That study is about them, not about you. It is here because it is the difference between a file and a decision.

Every check

Each line is one HTTP observation with a published rule, so you can rerun any of them yourself. Most are the same tomorrow if you are: the two that are not are the bot gate and the pricing page, which answer inconsistently on their own, which is why those run more than once and say so when the tries disagreed. PASS and PART are counted. UNMEASURED means we could not evaluate it, N/A means it does not apply to a product like yours, and neither is in the score or its denominator. See the formula

A · Discovery

FAIL
Docs readable without JavaScriptOnly 1,863 characters render without JS, on https://docs.sentry.io/platforms/apple/data-management/ rather than on https://docs.sentry.io/Most agents fetch HTML, they do not run your bundle. An empty shell reads as an empty product.
