An analysis workflow for T-cell and B-cell receptor sequencing data, which measures immune-cell diversity, expansion, and receptor patterns.

In plain words
What is it for?
Use it to identify and track clonotypes, measure repertoire diversity and clonality, study V(D)J and CDR3 patterns, predict epitope specificity, and connect receptor clones with single-cell traits.
Why use it?
It helps researchers turn large receptor-sequencing datasets into evidence about immune responses and possible antigen recognition.

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

tooluniverse-immune-repertoire-analysis 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.

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.

ToolUniverse Immune Repertoire Analysis

Comprehensive skill for analyzing T-cell receptor (TCR) and B-cell receptor (BCR) repertoire sequencing data to characterize adaptive immune responses, clonal expansion, and antigen specificity.

Overview

Adaptive immune receptor repertoire sequencing (AIRR-seq) enables comprehensive profiling of T-cell and B-cell populations through high-throughput sequencing of TCR and BCR variable regions. This skill provides an 8-phase workflow for:

  • Clonotype identification and tracking
  • Diversity and clonality assessment
  • V(D)J gene usage analysis
  • CDR3 sequence characterization
  • Clonal expansion and convergence detection
  • Epitope specificity prediction
  • Integration with single-cell phenotyping
  • Longitudinal repertoire tracking
