Use nbstripout when an agent needs to clean Jupyter or IPython notebooks for version control so reviews stay readable and repositories do not accumulate bulky output blobs. Invoke this instead of using Jupyter normally when the task is specifically notebook hygiene at commit time or in a verification pass, not authoring or running notebooks. The scope boundary is narrow and concrete: strip outputs and selected metadata from notebook files or enforce that clean state in Git, which keeps this distinct from broader notebook platforms or editor tooling.
