metabolomics-peak-detection

metabolomics-peak-detection is a skill for Claude Code, Codex from TianGzlab/OmicsClaw. It costs 78 tokens per session (828 once invoked), scanned A, original, Apache-2.0.

A peak-finding tool for a CSV table containing metabolomics feature intensities. It identifies prominent peaks separately for each sample using configurable detection settings.

In plain words
What is it for?
Use it to detect peaks by prominence, height, and distance, then save the detected peaks and a report.
Why use it?
Large intensity tables can contain more signal than a person can inspect manually. Automated peak detection makes those candidate signals easier to collect and review.

    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.

Token cost

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.

Security

Grade A, and why

metabolomics-peak-detection 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 17d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (_api.py, examples/example_step.py, peak_detect.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

When to use

Detect peaks on tabular sample signals ordered by retention time. This is not raw mzML peak extraction; run XCMS externally for that workflow.

Use from a step

import pandas as pd
from skills._sdk.notebook import load_skill, read_input, write_output
library = load_skill("metabolomics-peak-detection")
data = read_input('features.csv', reader=pd.read_csv)
result = library.detect_peaks(data)
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

detect_peaks(data, *, sample_cols=None, prominence=10000.0, height=None, distance=5)

Detect per-sample peaks after sorting rows by retention time.

:param data: DataFrame with mz, rt and numeric sample intensities. :param sample_cols: Explicit columns; None uses the CLI intensity/sample name detection. :param prominence: CLI default 10000; adjust to the intensity scale. :param height: CLI default None; optionally require a minimum peak height. :param distance: CLI default 5; minimum separation in sorted row positions, not seconds. :returns: A new peak DataFrame with diagnostics in attrs['run_info']. :raises ValueError: No sample columns match or peak parameters are invalid.

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.

peaks_figure(data)

Plot detected peak intensity against retention time.

:param data: Peak table returned by detect_peaks. :returns: A matplotlib Figure. :raises KeyError: Required peak columns are absent.

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.
