Show HN: Chelis, a tensor language agents can write and prove (github.com)

We just open sourced Chelis, a programming language we built focused on agent authorship and human supervision. You can find a longer intro on our site: https://chelis.ch/blog/launch/ But here are the key things a HN reader might like to know:

* Statically typed, compiled, functional language, with heavy influences from ML family languages

* Built for agent authorship of programs across the compiler, MCP, skills, and remdiation paths

* Formal methods baked in via SMT and related solvers being connected with the type system in the compiler

* Rich support for numerical programs and mathematically rich domains like quant finance and quant econ

* GPU support is in an experimental state, for folks who want to build from source and run on AMD or Apple acceleration

* All built in Rust

From our experience, agents can already write Chelis as well as they can write Python. And they are a lot less overconfident in incorrect approaches with all the help Chelis provides.

Several of us on the core team are hanging out on HN. Drop us a comment if you check out the work.
