• python-message-bus-outbox

• python-structlog-logging

  Use when setting up logging or writing log calls in a Python service. Triggers on `import logging`, `import structlog`, edits to `app/common/logging.py` or `app/api/middleware/`, on user questions about logging, JSON logs, correlation IDs, structured logging, log levels.

• python-typing-idioms

Triggers on `.py` files with type annotations; on imports from `typing`, `typing_extensions`, `collections.abc`; on user questions about type hints, Protocol, generics, NewType, PEP 695.

• python-value-objects
