Inspiration
Imagine a student engineering team handing a bench prototype to the next team. The test report is named bench-test-r03.pdf, but the document itself says R02. A filename checklist marks the report as present, and the next team could end up following an outdated test procedure. That gap inspired HandoffProof.
What it does
HandoffProof is a read-only Uliya Skill that checks one authorized NAS folder against an approved delivery list. It reports which files match, which need correction, and which could not be verified. Each finding includes the available file evidence and, when needed, a next action. After making corrections, the user can rerun the same list.
How we built it
I used the official UGOS Skill Creation Tool to define a Markdown workflow for Uliya’s registered file and document experts. The workflow lists the authorized folder, checks item IDs and revisions in TXT and PDF files, and rechecks file fingerprints before reporting. OpenAI Codex assisted with documentation research, Skill authoring, and offline testing.
Challenges we ran into
An incomplete folder listing can make a file look absent. HandoffProof reports Missing only when two complete, consistent listings both show that the expected file is absent. If coverage is uncertain, the item stays Unverified. If a file changes during the review, its earlier evidence is invalidated.
Accomplishments that we're proud of
The Skill package passed the official static checker with zero errors or warnings. All 30 offline decision tests passed using simulated observations, including incomplete listings, PDF evidence attributed to the wrong file, and changed file fingerprints.
What we learned
A file’s name can help locate it, but the printed revision is what lets the receiving team check it against the approved list. I also learned that a useful handoff report needs to show where its evidence stops, so the recipient knows what still needs checking.
What's next for HandoffProof
If selected for Round 2, I’ll install HandoffProof on the assigned UGREEN AI NAS and test whether the experts return complete folder listings and traceable PDF excerpts. I’ll run the original handoff, rerun it after correcting the files, and check that a folder listing that hits the scan limit leaves the unseen item Unverified.
