2
3	Use this skill to convert a small numeric matrix into a chunked, compressed Zarr store and inspect a deterministic summary of its layout.

5	## What This Skill Does
6
7	- reads a toy tabular matrix
8	- writes a local Zarr v2 array with fixed chunking and Blosc compression
9	- reports shape, chunk layout, compressor choice, and summary statistics
10
11	## When To Use It
12
13	- when you need a starter for `chunking-sharding`
14	- when you want a repo-local example of Zarr plus `numcodecs`
15	- when you need a tiny test fixture for chunked scientific array storage
16
17	## Run
18
19	```bash
20	python3 skills/data-acquisition-and-dataset-handling/zarr-chunked-array-store-starter/scripts/run_zarr_chunked_array_store.py --input skills/data-acquisition-and-dataset-handling/zarr-chunked-array-store-starter/examples/toy_matrix.tsv --store-out scratch/zarr/toy_matrix.zarr --summary-out scratch/zarr/toy_matrix_summary.json
21	```
22
23	## Notes
24
25	- The starter writes Zarr format 2 explicitly so classic compressor settings remain deterministic.
26	- The example is intentionally tiny and local; scale chunking decisions against real workloads before production use.
