A Proof Receipt is a lightweight verification field attached to a Ticket (or work item) that an agent must "sign" to demonstrate it has genuinely verified a task, rather than merely moving it to a "done" status.
Concept and Motivation
Alex Damis advocates for proof receipts as a structural mechanism to make autonomous agent runs trustworthy. The core problem they address is that an agent can trivially mark work complete without having actually verified the outcome — producing a false sense of progress. The proposed solution is minimal in design: add a dedicated field on each ticket where the agent must deposit a verification proof or signature before closure. →
As Damis frames it:
"What if there was just a simple field on each one that said verification proof or some sort and the agent just basically had to like sign it."
The claim underlying this proposal is that agents need proof receipts to make autonomous runs trustworthy — without them, task completion is just a status change with no evidentiary backing. →
Role in the Ticket Structure
Proof receipts are positioned as a part of the Ticket schema itself, not as an external audit mechanism. By embedding the verification field directly in the work item, the receipt travels with the task through whatever workspace or orchestration layer manages it, making verification a first-class property of the unit of work rather than an afterthought. →
Points of Disagreement
No dissenting voices appear in the current graph material. The concept is presented as an open design proposal rather than an established standard, leaving open questions about what constitutes a valid "proof" (a hash, a log reference, a structured attestation, etc.) and how agents would be prevented from trivially generating a fake signature.
