我爱做小工具：一个具体的问题，配一个能把它做完的 AI Agent。下面这些都在用，也都还在改。
| 项目 | 它做什么 |
|---|---|
| PBlossom | 梅花易数起卦、干支与节气查询，结果一键复制给 AI 细读。网页版 · 微信小程序 |
| Praxis | 陪你做数学建模：读题、建模、独立验证，最后写成有依据的报告 |
| 知衢 Zhiqu | 高考、读研、求职的规划技能，问卷加 Agent，用官方数据算方案。在线问卷 |
| Ubinam | 一张照片在哪拍、何时拍，并说清楚有几成把握 |
| MayoSocratic | 先问再答：分阶段问清情况，先排查危险信号再给建议 |
I build small tools that pair one concrete problem with an AI agent that can see it through:
- PBlossom: casts I Ching hexagrams and reads the traditional Chinese calendar. Try it (Chinese UI).
- Praxis: a math-modeling partner that goes from problem statement to a model you can check and a report you can defend.
- Ubinam: tells you where and when a photo was taken, and how sure it is.
- MayoSocratic: a skill that asks before it answers.
