Inspiration
Parents who grade daily workbooks at home end up with piles of pages, and repeated mistakes go unnoticed. These pages are also children's personal data, so a home NAS is a natural place to keep them.
What it does
Worksheet Coach finds graded worksheet photos in the NAS photo backup, files each page to the right child, lists wrong questions by unit, drafts a short note for tonight, and builds a monthly weak-spot report. It never solves questions for the child and never invents a mark it cannot read.
How I built it
It is a Markdown-only Uliya Skill. A parent Skill delegates to the photo, file, document and knowledge agents in a fixed order and passes only real results between steps. Claude Code was used for drafting and test analysis. A local Qwen2.5-VL 7B model was used for bench tests only and is not part of the package.
Challenges
On four real graded exam pages with 17 questions, a single classification silently misread seven. Searching for correct and wrong marks separately and treating disagreement as unclear misread none, but left 11 questions for the parent to confirm.
What I learned
For children's records, a visible unclear result is better than a confident wrong one.
What's next
Test home workbook photos and measure OCR, vision, albums and note quality on a real UGREEN AI NAS.
