Keep marimo notebooks running clean.
↻ Runs by itselfnotebook file changes
How the habit works.
You don't have to.
When does it start? How does it check its work? What does it remember?
One run, step by step.
Then it stops.
Stops after 5 notebooks or 2 fix rounds per run.
- 01
Lint
Your agent runs uvx marimo check on the notebook.
- 02
Run as script
It runs uv run on the notebook so script mode uses default data.
- 03
Check patterns
It removes if-guards on cells, try/except control flow and cross-cell mutation.
- 04
Check outputs
It makes sure each cell's output is its final expression.
- 05
Check dependencies
It adds a PEP 723 header if missing.
- 06
Run tests
It runs pytest on the notebook when it has test cells.
What it may do.
Nothing more.
It writes only in its own folder and asks you before anything goes out.
- Writes only in**/*.py, loops/marimo-notebook-check-loop/**
- Talks tono outside service
- Sendsnothing
- Your OKNothing goes out, so it needs no OK.
