How to use Prefect: what you can do with it

What is Prefect? Prefect is a workflow orchestration framework for building data pipelines in Python. Flow and task decorators turn a script into a production workflow with scheduling, caching, retries and event-based automations, and runs are tracked in a self-hosted Prefect server or the managed Prefect Cloud dashboard. Agent setup guides connect coding agents to Prefect through plugins or MCP.

How do I use it? Install with pip install -U prefect or uv add prefect (Python 3.11+); then Decorate your functions with task and the entry point with flow, as in the GitHub stars example; run the script once with Python to execute the flow. Full steps below.
