What it does
Deposit Defender is a UGREEN AI NAS Skill for renters at move-out. It finds the move-in and move-out photos already in the user's personal NAS library, describes each one with a fixed prompt, pairs photos of the same room and surface, and labels each pair New, Already there, No change, or Undecided. After the user approves, it saves one Markdown report with capture times and SHA-256 values, and can quote deposit clauses from a lease file.
Labels are suggestions for the user to review; SHA-256 and EXIF do not show when damage happened, and this is not legal advice.
Status (stated plainly)
Static check passed (uliya-skill-kit checker, 0 errors, 0 warnings). A 22-case pairing test and a stand-in vision test (public-domain images with script-drawn marks; rules were revised after it, so it is not independent) were run locally, and a sample end-to-end run on a simulated NAS found, compared, saved and checked one report. Not yet run on a UGREEN NAS; no vision-vlm output has been seen.
AI tools used
Claude Code wrote the Skill and the test harness and served as the stand-in vision model in local tests. Details are in references/disclosure.md inside the Skill ZIP. The full proposal is attached as a PDF.
