Your local-first memory guardian and cyber bestie.
> Lumi isn't a cold cloud drive or a mechanical habit tracker. She's a tiny spirit living on your device who speaks your squad's slang, drops memes from months ago at the perfect moment, and stitches everyone's messy moments into a stunning memory scroll. > > Lumi 不是一个冷冰冰的网盘，也不是机械的打卡助手。她是一个住在你设备里、懂你们圈子黑话、会接梗，还能把日常碎片拼成灿烂画卷的赛博精灵。

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted, and 20 counted toward the lift figure. The other 3 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of +39 percentage points is the difference between those two pass rates over the 20 comparable cases.
The per-case answers from this run were removed by the retention sweep, so the case table below shows the verdicts without the text either arm produced. The counts above were recorded at the time and are unaffected. Answers are now kept for 180 days.
Other measured skills in the registry, with their headline benchmark lift.
