modern-python SKILL.md skillA

modern-python from mycelium-io/mycelium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add mycelium-io/mycelium/modern-python@git:20260317.1be8d35

Pins git:20260317.1be8d35 in mdr.lock. Pin the fingerprint instead.

Modern Python tooling practices for the mycelium project. Use when installing dependencies, running tools, managing environments, or writing Python code. Always active as a background reference.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Modern Python Practices

This project uses **uv** for package management, **ruff** for linting/formatting, and **pytest** for testing.

## Core Rules

| Do | Don't |
|----|-------|
| `uv add <pkg>` | Edit pyproject.toml deps manually |
| `uv add --group dev <pkg>` | `pip install <pkg>` |
| `uv sync --group dev` | `pip install -r requirements.txt` |
| `uv run pytest` | `python -m pytest` or bare `pytest` |
| `uv run ruff check .` | Bare `ruff check .` |
| `[dependency-groups]` for dev tools | `[project.optional-dependencies]` |
| `uv run python script.py` | `python script.py` (may use wrong env) |

## Quick Reference

```bash
# Install all deps (including dev)
uv sync --group dev

# Add a new dependency
uv add httpx
uv add --group dev pytest-cov

# Remove a dependency
uv remove some-package

# Run any tool through uv
uv run pytest tests/ -x -q
uv run ruff check .
uv run ruff format .
uv run python -c "import mycelium"

# Run with a temporary dep (not added to project)
uv run --with rich python -c "from rich import print; print('hello')"
```

How to install

The exact contents, by fingerprint
mdr add mycelium-io/mycelium/modern-python@sha256:c725130c71c24913

The line at the top of this page pins the label git:20260317.1be8d35, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
