genomics-epigenomics

genomics-epigenomics is a skill for Claude Code, Codex from TianGzlab/OmicsClaw. It costs 79 tokens per session (1,019 once invoked), scanned A, original, Apache-2.0.

A tool for summarizing genomic peak files from experiments such as ATAC-seq, ChIP-seq, and CUT&Tag. Peak files mark genome regions where a signal was detected.

In plain words
What is it for?
Use it to summarize peak counts, widths, scores, and chromosome distributions from BED, narrowPeak, broadPeak, or CSV files, and produce tables and a report.
Why use it?
It provides consistent counts and measurements without requiring the tool to call peaks from raw sequencing data or handle single-cell ATAC data.

    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

genomics-epigenomics 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 15d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (_api.py, examples/example_step.py, genomics_epigenomics.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

Load this skill for the file-based analysis named in the description. The function library and CLI share the same calculations; no external aligner, assembler, caller or annotation service is started.

Use from a step

from skills._sdk.notebook import load_skill, read_input, write_output
library = load_skill("genomics-epigenomics")
data = read_input("input.bed", reader=library.read_records)
result = library.analyze(data)
write_output(result, "tables/result.csv")
write_output(library.distribution_figure(result), "figures/distribution.png")

Run examples/example_step.py through the step runner for a small, hand-worked synthetic fixture. It asserts known summary values. The reader materializes the input in memory; use bounded FASTQ reads or pre-filter large genomic files before loading them.

API

read_records(path: str | Path) -> pd.DataFrame

Read records through read_input(path, reader=library.read_records).

:param path: Existing input file in the format documented under Inputs and outputs. :returns: Parsed records as a DataFrame. :raises ValueError: Input values or file structure cannot be parsed.

analyze(data: pd.DataFrame, *, assay: str='chip-seq') -> pd.DataFrame

Compute epigenomics summaries and return a new table, leaving data unchanged.

:param data: Records containing chrom, start, end. :param assay: CLI default chip-seq; atac-seq and cut-tag change descriptive expectations. :returns: Result table with diagnostics and summary in attrs['run_info']. :raises ValueError: Required columns are absent or records are empty or invalid.

run_info(data: pd.DataFrame, *, keep: bool=True) -> dict

Return the analysis diagnostics and summary.

:param data: Result returned by analyze. :param keep: Keep diagnostics by default; the CLI passes False. :returns: Independent diagnostics dictionary. :raises ValueError: analyze has not populated diagnostics.

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.
