Skelet is a new config storage/validation library for Python. The goal is to provide a minimal API for collecting settings in one place, while ensuring thread safety, transactionality, and type/value correctness. Configs can be loaded and validated from TOML, YAML, JSON, and environment variables.
Most libraries like pydantic-settings or dynaconf are great for model-based settings, but they aren’t thread-safe out of the box and don’t handle config mutation atomically. Skelet manages assignments under per-field mutexes (so you won’t see half-applied values or race conditions in concurrent apps), and it supports field-level docs, validation, secret fields (hiding any type), and hooks for value changes.
Meant for production scenarios where config safety matters (services, CLI tools, distributed systems), but also handy for scripts that need explicit config handling.
Many old Python libraries got their mirrored async reflections after the popularization of asynchrony. As a result, the entire Python ecosystem was duplicated. Superfunctions are the first solution to this problem, which allows you to partially eliminate code duplication by giving the client the opportunity to choose (similar to how it is done in Zig) whether to use the regular or asynchronous version of the function.

You can use 2 different versions of the same library in the same program.
You can use incompatible libraries in the same project, as well as libraries with incompatible/conflicting dependencies.
It's easy to share written scripts. The script file becomes self-sufficient - the user does not need to install the necessary libraries.
The library does not leave behind "garbage". After the end of the program, no additional files remain in the system.
But you know what? There is no single standard for such comments. Seriously.
The internal implementation of reading such comments is also different. Someone uses regular expressions, someone uses even more primitive string processing tools, and someone uses full-fledged parsers, including the Python parser or even written from scratch.
This is exactly the problem that this library solves. It describes a simple and intuitive standard for action comments, and also offers a ready-made parser that creators of other tools can use.
