bio-clip-seq-clip-qc

bio-clip-seq-clip-qc is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 131 tokens per session (6,032 once invoked), scanned A, a copy of bio-clip-seq-clip-qc, MIT.

A quality-checking workflow for CLIP-seq libraries, which are sequencing samples used to measure RNA-binding-protein interactions. It examines read retention, mapping, duplication, reproducibility, contamination, and enrichment.

In plain words
What is it for?
Use it to assess eCLIP and related libraries, compare replicates, inspect input controls, and check commonly used ENCODE quality measures.
Why use it?
A library can produce plausible-looking results while having too few useful reads, excessive repetition, contamination, or poor agreement between replicates. Quality checks show where a sample is reliable or failing.

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

bio-clip-seq-clip-qc 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/clip_qc.sh), 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.

How it starts

The opening of the file, as written. The whole thing — 402 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: preseq 3.2+, picard 3.1+, samtools 1.19+, bedtools 2.31+, deeptools 3.5+, idr 2.0.4+, MultiQC 1.21+, RSeQC 5.0+, pysam 0.22+, fastp 0.23+.

Before using code patterns, verify installed versions match. If versions differ:

  • Python: pip show <package> then help(module.function) to check signatures
  • CLI: <tool> --version then <tool> --help to confirm flags

If code throws unexpected errors, introspect the installed binary and adapt the example to match the actual CLI rather than retrying.

CLIP-seq Quality Control

"Did my CLIP library pass?" -> Assess preprocessing retention, alignment rate, library complexity, replicate reproducibility (IDR), fraction reads in peaks (FRiP), read-distribution metagene, rRNA/snoRNA contamination, fragment-length distribution, and SMInput vs IP enrichment. ENCODE eCLIP compliance is the canonical bar: >= 1M unique fragments per replicate, IDR rescue and self-consistency ratios both < 2, FRiP >= 0.005 (narrow-binding), library complexity rising linearly with depth on preseq lc_extrap. A library can fail at any of these stages, and the failure mode determines whether the data is salvageable.

  • CLI (library complexity, primary QC): preseq lc_extrap -B -P aligned.bam -o complexity.txt
  • CLI (FRiP after peak calling): bedtools intersect -c -s -a peaks.bed -b dedup.bam | awk '{s+=$NF} END{print s}' then divide by total reads
  • CLI (IDR, ENCODE convention): idr --samples rep1.sorted.bed rep2.sorted.bed --input-file-type bed --rank 5 --output-file idr.out --idr-threshold 0.05 --plot
  • CLI (read distribution / metagene): RSeQC read_distribution.py -i dedup.bam -r gencode.v38.bed + geneBody_coverage.py -i dedup.bam -r housekeeping.bed -o gb
  • CLI (rRNA contamination check): samtools idxstats dedup.bam | awk '$1 ~ /rRNA|45S|18S|28S/ { sum+=$3 } END {print sum}'
  • CLI (consolidated report): multiqc <run_dir> aggregates FastQC + cutadapt + STAR + umi_tools + preseq + samtools stats

What ships with it

Changes

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.
