How to use COUTCHECK: scan output for leaks before you send it

COUTCHECK scans a response for PII and toxicity, optionally validating JSON, and returns the entities found so you can redact, block, or regenerate.

The response is the other trust boundary. COUTCHECK catches a leaked email or a toxic line before your user sees it.

crowkis cli

> COUTCHECK "Sure! Email john.doe@acme.com for the refund."
1) "fail"
2) "pii: [email:john.doe@acme.com]"
3) "toxic: []"
4) "json: n/a"

Act on the verdict per failure mode — redact the PII and continue, or regenerate.
