- MCP, LSP and Skill support.
- Feature rich Lua SDK. Custom hooks, agents, commands and control flow.

If you are interested in what you can do feel free to peek at [my configuration](https://github.com/Lommix/dotfiles/blob/master/config/blitzdenk/blitz.lua)

Creating a harness is a fun experience. Mid-dev zig 0.16 dropped, and I had an absolute blast integrating zig’s the new async capabilities. Before everything was a poll based state machine.

The project started 3 months ago. Sits at around 26k lines of zig code. No dependencies outside std and vendored Lua.

## Why

For the sake of learning and recreation, inspired by Neovim and PI. Because programming is fun. I have no other reason. Also, I am stubborn. I want to own my tools and dislike package managers.

### Supported Zig versions

0.16

### AI / LLM usage disclosure

Obviously it’s in the nature of this project, that AI is being used. It’s still mostly handwritten. I am perfectly capable of writing slop without AI.
