python-typing-patterns from aiskillstore/marketplace is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Python type hints and type safety patterns. Triggers on: type hints, typing, TypeVar, Generic, Protocol, mypy, pyright, type annotation, overload, TypedDict.
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
# Python Typing Patterns
Modern type hints for safe, documented Python code.
## Basic Annotations
```python
# Variables
name: str = "Alice"
count: int = 42
items: list[str] = ["a", "b"]
mapping: dict[str, int] = {"key": 1}
# Function signatures
def greet(name: str, times: int = 1) -> str:
return f"Hello, {name}!" * times
# None handling
def find(id: int) -> str | None:
return db.get(id) # May return None
```
## Collections
```python
from collections.abc import Sequence, Mapping, Iterable
# Use collection ABCs for flexibility
def process(items: Sequence[str]) -> list[str]:
"""Accepts list, tuple, or any sequence."""
return [item.upper() for item in items]
def lookup(data: Mapping[str, int], key: str) -> int:
"""Accepts dict or any mapping."""
return data.get(key, 0)
# Nested types
Matrix = list[list[float]]
Config = dict[str, str | int | bool]
```
## Optional and Union
```python
# Modern syntax (3.10+)
def find(id: int) -> User | None:
pass
def parse(value: str | int | float) -> str:
pass
# With default None
def fetch(url: str, timeout: float | None = None) -> bytes:
pass
```
## TypedDict
```python

How to install
mdr add aiskillstore/marketplace/python-typing-patterns@sha256:6055a1e8d6ae6410The line at the top of this page pins the label git:20260113.222b7de, 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.
