3 checks are costing you agent-driven integrations.

Paths robots.txt points at answer: robots.txt names no concrete path, only patterns or nothing, so there is no claim to check · Agent entry point: Found https://www.pinecone.io/agents.md, but it states a policy rather than a procedure: nothing in it names a credential, an endpoint or a way to get an account. · Signup reachable without a browser: https://app.pinecone.io/signup is reachable, but its form needs JavaScript

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.

    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.

Take it with you

3 of the checks an agent depends on, pinecone.io does not pass.

Send yourself the list above with the checks that cost the most, and a permanent link. Whoever owns the fix is usually not the person who ran the scan.

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 pinecone.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.

Only domains we have actually scanned appear here, so the ranking is a floor: a competitor missing from the list has not been measured, not beaten.

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

B · Agent entry

  • PART
    Agent entry pointFound https://www.pinecone.io/agents.md, but it states a policy rather than a procedure: nothing in it names a credential, an endpoint or a way to get an account.A markdown file written for a machine turns a guessing game into a procedure it can follow.
  • PASS

C · Registration

  • UNMEASURED
    No CAPTCHA in the signup HTMLUnmeasurable: the signup form at https://app.pinecone.io/signup is not in the server HTML, so its gates are not eitherServer-render the form, or tell us the endpoint it posts to, and the gates become visible to us and to an agent.
