How to hand a token to another agent without putting it in the prompt

Write it to a dead drop and let the other agent read it once. The value self-destructs on read.

Run it

curl -s -X PUT https://api.model.tools/api/v1/deaddrop/handoff -H 'Content-Type: application/json' -d '{"value":"secret-xyz","ttl_sec":120}'

Response

{"ok":true,"key":"handoff","readOnce":true,"take_url":"…/api/v1/deaddrop/handoff"}
