About Lefts

Lefts is a very simple domain specific language for building complex machine learning workflows from simple ones. Starting with your favourite machine learning models, you can use Lefts operations to:. Without making subsequent model fitting, evaluation or experimentation any more complex than it was with the original model. This implementation is built on top of the excellent Polars DataFrame library. E nsemble: Takes a set of models and makes them evaluate as one. F eed: Allows the output of one model to be used as a feature or target by another.

About UIPrompt

A visual component editor that turns your design into spec-grade prompts for Claude Code, Cursor, and v0. Design buttons, badges, checkboxes, and inputs, then get pixel-perfect AI output. UIPrompt is a visual component editor that writes spec-grade prompts with exact values, state diffs, theme-aware tokens, and accessibility rules. You are implementing a UI component in this codebase. Where Tailwind has no utility for an exact value, use arbitrary values (e.g. Do not substitute your own design taste, do not round values, and do not add visual features the spec does not mention.
