Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00337 |
| Opus 5 | $0.00000 | $0.00169 |
| Sonnet 5 | $0.00000 | $0.00067 |
| Haiku 4.5 | $0.00000 | $0.00034 |
Grade A, and why
skimage-regionprops-feature-extraction scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
scikit-image Regionprops Feature Extraction
Use this skill to extract deterministic morphology and intensity features from a toy image with scikit-image regionprops_table.
What it does
- creates a reproducible grayscale toy image with three bright ellipse-like objects
- thresholds and labels connected components locally
- summarizes per-object morphology and intensity features into compact JSON
- keeps the output stable enough for smoke tests and starter workflows
When to use it
- You need a local
feature-extractionstarter in the scikit-image ecosystem. - You want a minimal handoff point before building larger imaging or phenotype-analysis pipelines.
Example
./slurm/envs/scientific-python/bin/python \
skills/imaging-and-phenotype-analysis/skimage-regionprops-feature-extraction/scripts/run_skimage_regionprops_features.py \
--threshold 0.35 \
--out scratch/skimage-regionprops/summary.json
Verification
- Skill-local tests:
python3 -m unittest discover -s skills/imaging-and-phenotype-analysis/skimage-regionprops-feature-extraction/tests -p 'test_*.py' - Asset regeneration:
./slurm/envs/scientific-python/bin/python skills/imaging-and-phenotype-analysis/skimage-regionprops-feature-extraction/scripts/run_skimage_regionprops_features.py --out skills/imaging-and-phenotype-analysis/skimage-regionprops-feature-extraction/assets/toy_regionprops_summary.json
Notes
- This is a starter for the taxonomy leaf
feature-extraction. - The image is synthetic and deterministic; it is intended for scaffolding and verification rather than biological interpretation.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skimage-regionprops-feature-extraction is a skill published in the GitHub repository ma-compbio-lab/SkillFoundry (38 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 337 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
