I'm Skymly (落笔wys) — I write C# / .NET libraries where compile-time codegen and small runtime primitives do the heavy lifting, and I build AI coding agents on the side. My active work spans three open repos: Observables (reactive boundaries with R3 / System.Reactive), DesignPatterns (composable patterns + Roslyn diagnostics), and IsaacAgent (an AI coding agent for Binding of Isaac: Repentance Lua mods). I also contribute to MvvmAIO when it overlaps with MVVM generators.

我是 Skymly（落笔wys）—— 写 C# / .NET 库，靠编译期代码生成和精简的运行时原语干活，业余也做 AI 编程助手。主要活跃在三个开源仓库：Observables（基于 R3 / System.Reactive 的响应式边界）、DesignPatterns（可组合设计模式 + Roslyn 诊断），以及 IsaacAgent（面向《以撒的结合·重生》Lua mod 的 AI 编程助手）。也会在 MvvmAIO 协作 MVVM 生成器相关的工作。

Roslyn generators that turn .NET events, HTTP, and SignalR into R3 or System.Reactive streams — pick one reactive stack per app.

Roslyn 生成器，把 .NET 的 事件、HTTP、SignalR 转成 R3 或 System.Reactive 流——每个应用选一种响应式栈。

Lightweight pattern primitives — chain, strategy, factory registry, singleton, … — with source generators, analyzers (DP###), and code fixes. Composition over inheritance; not a MediatR-style framework.

轻量级模式原语——chain、strategy、factory registry、singleton 等——配 源生成器、分析器（DP###）和 代码修复。组合优于继承；不是 MediatR 风格的框架。

An AI coding agent for The Binding of Isaac: Repentance Lua mod development — a Cursor/OpenCode-style desktop app with Isaac-specific knowledge, tools, and workflows built in. Local RAG over 480+ modding docs, 16 agent tools, 9 task skills, and multi-provider LLM (OpenAI-compatible / Ollama). Built with .NET 8 + Avalonia 11.
