Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 3 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
What it costs to keep this loaded
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 | $0.00096 | $0.00934 |
| Opus 5.5 | $0.00038 | $0.00374 |
| Sonnet 5.5 | $0.00019 | $0.00187 |
| Haiku 4.5 | $0.00010 | $0.00093 |
Grade A, and why
metabolomics-statistics 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 19d 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
metabolomics-statistics
When to use
Test two explicit sample groups using Welch, ranksums, ANOVA or Kruskal. Use metabolomics-de for the ctrl/treat contrast and PCA CLI.
Use from a step
import pandas as pd
from skills._sdk.notebook import load_skill, read_input, write_output
library = load_skill("metabolomics-statistics")
data = read_input('features.csv', reader=lambda path: pd.read_csv(path, index_col=0))
result = library.test_groups(data, group1_prefix='ctrl', group2_prefix='treat')
write_output(result, 'tables/result.csv')
examples/example_step.py runs a seeded synthetic
example through the step runner and writes a table and Figure. Computations
return new DataFrames, leave the input unchanged and expose diagnostics through
run_info(result). Plotting functions write no files.
API
test_groups(data, *, method='ttest', alpha=0.05, group1_prefix=None, group2_prefix=None, group1_cols=None, group2_cols=None)
Return two-group test statistics and BH-adjusted p values.
:param data: Numeric feature-by-sample DataFrame with feature IDs as its index. :param method: CLI default ttest; wilcoxon (ranksums), anova or kruskal also work. :param alpha: CLI default .05; diagnostic significance threshold. :param group1_prefix: CLI default None; prefix selecting the reference samples. :param group2_prefix: CLI default None; prefix selecting the comparison samples. :param group1_cols: Explicit reference columns; supply together with group2_cols. :param group2_cols: Explicit comparison columns; overrides prefix selection. :returns: A new DataFrame with grouping and significance diagnostics. :raises ValueError: A group is empty, overlaps another or is only partly specified.
run_info(data, *, keep=True)
Read diagnostics attached to a returned table.
:param data: DataFrame returned by this library. :param keep: Default True; use False in the CLI to remove diagnostics. :returns: An independent dictionary describing the run. :raises ValueError: The table carries no run_info.
What ships with it
7 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.

metabolomics-statistics is a skill published in the GitHub repository TianGzlab/OmicsClaw (161 stars, last pushed 19d ago), licensed Apache-2.0. It adds 96 tokens to every session and 934 once invoked, about $0.0004 per session on Opus 5.5. 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.
