2
3	Use this skill to round-trip a small integer matrix through a deterministic `numcodecs` compressor and inspect the encoded payload summary.
4
5	## What This Skill Does
6
7	- reads a tiny tabular integer matrix
8	- encodes the matrix bytes with `numcodecs.Blosc`
9	- decodes the payload and verifies lossless recovery
10	- reports shape, dtype, encoded byte count, and simple row statistics
11
12	## When To Use It
13
14	- when you need a starter for `compression-decompression`
15	- when you want a repo-local `numcodecs` example outside the full Zarr stack
16	- when you need a small regression fixture for round-trip codec checks
17
18	## Run
19
20	```bash
21	./slurm/envs/data-tools/bin/python skills/data-acquisition-and-dataset-handling/numcodecs-compression-decompression-starter/scripts/run_numcodecs_compression_decompression.py --input skills/data-acquisition-and-dataset-handling/numcodecs-compression-decompression-starter/examples/toy_matrix.tsv --out scratch/numcodecs/toy_matrix_summary.json
22	```
23
24	## Notes
25
26	- The codec configuration is fixed so the canonical asset stays stable.
27	- The example is intentionally tiny and integer-only; validate codec choices on real payloads before production use.
