Use Litestar's event emitter and listener system with `@listener`, `request.app.emit()`, multiple listeners per event, multi-event listeners, shared argument contracts, and custom event emitter backends. Use when decoupling async side effects, fanout-style in-process notifications, or transport-triggered domain events inside a Litestar app. Do not use for startup/shutdown lifecycle hooks, request/response interception, or broker-backed pub-sub systems that belong in app setup, lifecycle hooks, or channels.
Develop Python applications using modern patterns, uv, functional-first design, and production-first practices. Use this whenever working with .py files, pyproject.toml, uv commands, pip/pip3, poetry, virtualenv/venv, inline script metadata, or Python tooling like pytest, mypy, ruff, asyncio, itertools, functools, or dataclasses. If the task involves running Python, managing Python dependencies, creating environments, or building Python packages, load this skill and prefer uv-oriented workflows.
