juxt/allium: A language for sharpening intent alongside implementation. is a very exciting project. Specifically, a specification language for the behavior of software systems. A language for which there is no runtime environment or compiler, except the LLM. Implemented as Agent Skills. Super exciting because it also includes a Distill, with which you can analyze existing software and retroactively build specifications, or work out a specification in an interview process with the AI that is much more precisely understandable to an LLM than general English. A funny detail on the side: I tried Allium with Qwen3-Coder-Next, my current favorite model for local hosting, in pi.dev. I couldn't install the binary for Allium (a syntax checker and linter) with homebrew, so pi.dev simply downloaded the binary and installed it itself.
