Mudyla - Multimodal Dynamic Launcher

A script orchestrator: define graphs of Python/Bash/etc actions in Markdown files and run them in parallel under Nix environments.

Totally Claude'd.

Based on some ideas from DIStage Dependency Injection, Grandmaster Meta Build System and ix package manager.

Successor of mobala

If you use Scala and SBT, Mudyla works well with Squish.

An example of a real project using this gloomy tool: Baboon.
