bio-workflows-tcr-pipeline

bio-workflows-tcr-pipeline is a skill for Claude Code, Codex from thesecondfox/skill. It costs 40 tokens per session (558 once invoked), scanned A, original, MIT.

A workflow for studying T-cell and B-cell receptor sequencing data. It identifies clonotypes—groups of immune cells sharing the same receptor sequence—and measures their diversity and changes.

In plain words
What is it for?
Use it to extract clonotypes from FASTQ files, calculate repertoire diversity, study somatic mutations and cell lineages, and compare receptor gene usage or clone changes.
Why use it?
It connects receptor sequence processing with repertoire statistics, mutation analysis, and visual summaries in one analysis path.

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-workflows-tcr-pipeline 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

Version Compatibility

Reference examples tested with: MiXCR 4.6+, VDJtools 1.2.1+

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

  • CLI: <tool> --version then <tool> --help to confirm flags

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

TCR/BCR Analysis Pipeline

"Analyze my TCR/BCR repertoire sequencing data end-to-end" → Orchestrate MiXCR clonotype extraction, VDJtools diversity/repertoire analysis, Immcantation SHM and lineage analysis, and visualization of V/J gene usage and clonal dynamics.

Pipeline Overview

FASTQ → MiXCR align → Assemble → Export → VDJtools diversity → Visualization

Step 1: MiXCR Processing

# Align reads to V(D)J segments
mixcr align -s hsa -p rna-seq \
    R1.fastq.gz R2.fastq.gz \
    aligned.vdjca

# Assemble clonotypes
mixcr assemble aligned.vdjca clones.clns

# Export
mixcr exportClones clones.clns clones.txt

Step 2: VDJtools Analysis

# Convert to VDJtools format
vdjtools Convert -S mixcr clones.txt vdjtools/

# Diversity metrics
vdjtools CalcDiversityStats vdjtools/clones.txt diversity/

# Sample overlap
vdjtools CalcPairwiseDistances vdjtools/*.txt overlap/

Step 3: Visualization

# Spectratype plot
vdjtools PlotFancySpectratype vdjtools/clones.txt spectra/

# V usage
vdjtools PlotFancyVJUsage vdjtools/clones.txt usage/

QC Checkpoints

  1. After alignment: Check V/J assignment rate (>70% typical)
  2. After assembly: Verify clonotype count and coverage
  3. After diversity: Compare metrics to expected range

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.

bio-workflows-tcr-pipeline is a skill published in the GitHub repository thesecondfox/skill (3 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 558 once invoked, about $0.0002 per session on Opus 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.
