From the source SKILL.md

Rechunking is one of the most expensive operations you can perform on a Zarr dataset. Depending on chunk size and dataset volume, rechunking can take anywhere from approximately 6 minutes to over 46 hours (Nguyen et al., 2023, [DOI: 10.1002/essoar.10511054.2](https://doi.org/10.1002/essoar.10511054.2)). The operation rewrites every byte of data, and an interrupted or misconfigured rechunk can corrupt an entire dataset. This skill wraps the rechunk.py script with a safety-first workflow: validate inputs, estimate costs, rechunk to a new location, verify outputs, and only then swap the result…
