I build small AI tools for people who make things — Agent Skills, macOS apps, and the occasional script that saves an afternoon. Then I explain them to ~120k followers across Chinese video platforms.
Most of what I publish here came out of doing the actual job first. If a repo documents a trap, it's because I fell into it.
Currently shipping
| chatcut-to-fcpxml | ChatCut → Final Cut Pro. Hands a ChatCut timeline off to FCP as an editable FCPXML project — frame-exact cuts, keyframed zooms and iTT captions intact. An Agent Skill for Claude Code and Codex. ▶ Walkthrough |
| Doubletake | Two cameras, one subject, side by side. A macOS app that lays two shoots on one EXIF timeline, pairs the corresponding frames, compares them with synced zoom, and exports the result sized for 4K video inserts. |

我做给创作者用的 AI 小工具 —— Agent Skills、macOS app，还有一些能省下一下午的小脚本，然后把它们讲给各平台上大约 12 万关注我的人听。
这里放出来的东西基本都是先拿去干活、再整理成仓库的。如果某个仓库里写了一个坑，那是因为我自己先掉进去过。
在做的
| chatcut-to-fcpxml | ChatCut → Final Cut Pro。 把 ChatCut 时间线帧级精确地交接给 Final Cut Pro，关键帧推镜和 iTT 字幕都不丢。Claude Code 和 Codex 都能用的 Agent Skill。 ▶ 演示视频 |
| Doubletake | 两台相机，同一个东西，并排比。 macOS app：把两次拍摄铺在同一条 EXIF 时间轴上，配对出真正对应的两张，同步放大着看，再一键导出成能直接放进 4K 视频的对比图。 |
