Cryptid Field Office

About the Bureau

A serious system, in a slightly silly hat.

The Cryptid Field Office is a fictional bureau that takes every unexplained sighting seriously: cryptids, lights in the sky, figures on the stairs, spirits, and the occasional secret society. The humour lives in the bureaucracy. It is never aimed at anyone’s belief, and every society on file is invented.

Underneath, it is a real report-triage pipeline: public intake, AI screening, linking related reports, a human decision, and an audit trail. Swap Bigfoot for potholes and this is a city 311 system. The same pattern runs bug trackers, insurance claims and fraud review.

How it was built

Built for the DEV × Sanity challenge (Path Two), prompted into existence with Claude Code. The build log, prompts and dead ends are in the write-up and the repository.

  • One content lake

    Cases, subjects, regions, witnesses, red strings and settings live in one Sanity dataset. The public site, the Studio and the Case Board all read and write the same documents in real time.

  • A process as data

    A case moves through five stages defined with Sanity Workflows. The AI agent and a person use exactly the same actions and transitions. Where a case goes after triage is decided by code, never by the model.

  • Two agents, guarded

    The Field Investigator scores a report; the Cross-Referencer links related files. Faith-related reports are never auto-closed, the model may not rule on belief, and a daily budget and kill switch cap the AI.

  • A custom app on the content

    Staff use a Case Board built with the Sanity App SDK: a live corkboard where cases are pinned and red strings are drawn. It is not a read-only frontend.

For the judges

  1. File a report and watch the Field Investigator triage it live.
  2. Open the Director’s Desk and decide a case that needs a person. No login needed.
  3. Open the resulting case file to see the audit trail, red strings and witness record.
