writing-python skillA

writing-python is agent-read markdown (skill) from aleksandarbisevac/claude-plugins: How Python is written in this repo — free functions over classes, structured returns instead of mutated arguments, comprehensions, no module state, and the stdlib-only, annotation-free, Python 3.8 dialect the AST lints enforce. Covers modular structure and the import-layer rule, DRY without copying a helper into a second file, what makes a function testable from a `--selftest`, readability rules (guard clauses, named predicates, why-not-what docstrings), and the anti-patterns that have actually .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add aleksandarbisevac/claude-plugins/writing-python@git:20260823.0c7a50c
Exact content
mdr add aleksandarbisevac/claude-plugins/writing-python@sha256:88ebea887a5a935d

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
