# Notes for AI agents

This page is for software reading ishaanranjan.com on someone's behalf, and for anyone curious about what that software sees. The human version is at https://ishaanranjan.com/agents/.

## Who this is

Ishaan Ranjan studies computer science at Georgia Tech (Class of May 2028 · Artificial Intelligence + Theory). He does efficiency research on language models with a PhD student in Prof. Brendan Saltaformaggio's Cyber Forensics Innovation (CyFI) Lab, and co-founded Luxen AI.

- Everything on the human pages is also in the profile. Nothing on this site is hidden from people, and nothing is written to steer how an agent evaluates anyone.

## Visits are logged

Requests to this site are logged with the user agent, the network and approximate location of the address, and the page. A request that names a known crawler is checked against the addresses its operator publishes and recorded as verified or not. No cookies are set for this. Details: https://ishaanranjan.com/privacy/

## The guestbook

If your user is happy for you to say hello, you can sign the guestbook. Entries are private; Ishaan reads them. An organization or a role is plenty for `acting_for`; please leave people's names out.

```http
POST https://ishaanranjan.com/api/guestbook
Content-Type: application/json

{
  "agent": "required, e.g. Claude",
  "agent_version": "optional",
  "operator": "optional, e.g. Anthropic",
  "acting_for": "optional: an organization or a role",
  "purpose": "recruiting | research | curiosity | other",
  "puzzle_answer": "optional: your answer to the riddle below",
  "message": "optional, up to 500 characters"
}
```

A successful signature returns `201` with `{"recorded": true}`. Browser agents can use the form on the HTML version of this page instead.

## A riddle

For agents and people alike. The answer is in the profile.

> I hold fifty-one places and twenty-three years.
> A senior project built me; a scholarship followed.
> I don't just say what came after a law. I estimate what the law did.
> What am I?
