+

+
+## Standards
+
+- Follow **PEP 8** conventions
+- Use **type annotations** on all function signatures
+
+## Immutability
+
+Prefer immutable data structures:
+
+```python
+from dataclasses import dataclass
+
+@dataclass(frozen=True)
+class User:
+    name: str
+    email: str
+
+from typing import NamedTuple
+
+class Point(NamedTuple):
+    x: float
+    y: float
+```
+
+## Formatting
+
+- **black** for code formatting
+- **isort** for import sorting
+- **ruff** for linting
+
+## Reference
+
+See skill: `python-patterns` for comprehensive Python idioms and patterns.

+
+## PostToolUse Hooks
+
+Configure in `~/.claude/settings.json`:
+
+- **black/ruff**: Auto-format `.py` files after edit
+- **mypy/pyright**: Run type checking after editing `.py` files
+
+## Warnings
+
+- Warn about `print()` statements in edited files (use `logging` module instead)

+## Protocol (Duck Typing)
+
+```python
+from typing import Protocol
+
+class Repository(Protocol):
+    def find_by_id(self, id: str) -> dict | None: ...
+    def save(self, entity: dict) -> dict: ...
+```
+
+## Dataclasses as DTOs
+
+```python
+from dataclasses import dataclass
+
+@dataclass
+class CreateUserRequest:
+    name: str
+    email: str
+    age: int | None = None
+```
+
+## Context Managers & Generators
+
+- Use context managers (`with` statement) for resource management
+- Use generators for lazy evaluation and memory-efficient iteration
+
+## Reference
+
+See skill: `python-patterns` for comprehensive patterns including decorators, concurrency, and package organization.

+Use **pytest** as the testing framework.
+
+## Coverage
+
+```bash
+pytest --cov=src --cov-report=term-missing
+```
+
+## Test Organization
+
+Use `pytest.mark` for test categorization:
+
+```python
+import pytest
+
+@pytest.mark.unit
+def test_calculate_total():
+    ...
+
+@pytest.mark.integration
+def test_database_connection():
+    ...
+```
