ChatSpatial: Skill for Claude Code

.agents/skills/functional-analysis/SKILL.md

functional-analysis is a skill for Claude Code from cafferychen777/ChatSpatial. It costs 87 tokens per session (1,921 once invoked), scanned A, original, MIT.

A gene-set analysis that links a list of genes to biological processes and pathways. It supports over-representation analysis for selected genes, GSEA for a ranked list, and copy-number analysis in spatial tumor data.

In plain words
What is it for?
Use it to interpret differentially expressed genes, marker genes, or spatially variable genes; run pathway enrichment or GSEA; and examine spatial copy-number changes and tumor subclones.
Why use it?
It turns a long gene list into biological themes, helping explain what the genes may have in common. It also helps choose an analysis suited to the type of gene data available.

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

functional-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 8d 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.

Functional Analysis

Overview

This skill answers: What biological processes/pathways are represented by this gene set?

Two main approaches:

  1. Over-representation Analysis (ORA): Test if genes are enriched in pathways
  2. Gene Set Enrichment Analysis (GSEA): Use full ranked gene list

Plus specialized analysis: 3. CNV Analysis: Copy number variation in spatial context (tumor analysis)

Decision Tree: Which Method?

Q: What type of gene list do you have?
│
├─ Discrete gene list (DEGs, markers)
│   └─ Over-Representation Analysis (ORA)
│       ├─ Input: Gene list (up/down regulated)
│       ├─ Tests: Hypergeometric / Fisher's exact
│       └─ Output: Enriched pathways with p-values
│
├─ Ranked gene list (all genes with scores)
│   └─ Gene Set Enrichment Analysis (GSEA)
│       ├─ Input: All genes ranked by fold change/statistic
│       ├─ Tests: Running sum statistic
│       └─ Output: Enrichment scores, leading edge genes
│
└─ Spatial tumor data
    └─ CNV Analysis
        ├─ Infer copy number from expression
        ├─ Map CNV spatially
        └─ Identify subclones

Over-Representation Analysis (ORA)

When to Use

  • You have a discrete gene list (e.g., significant DEGs)
  • Want to know what pathways are enriched
  • Quick, interpretable results needed

Databases

Database Content Best For
GO (Gene Ontology) BP, MF, CC terms Broad functional annotation
KEGG Metabolic/signaling pathways Pathway diagrams
Reactome Curated pathways Detailed mechanisms
MSigDB Hallmarks, curated sets Cancer, immunology
WikiPathways Community pathways Specific processes

Workflow

Step 1: Prepare Gene List

Requirements:

  • Gene symbols or IDs (consistent naming)
  • Typically 50-500 genes works best
  • Separate up/down regulated if directional
Step 2: Run ORA

Use analyze_enrichment tool with:

  • gene_list: Your genes of interest
  • database: "GO_BP", "KEGG", "Reactome", etc.
  • background: All detected genes (important!)

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.

functional-analysis is a skill published in the GitHub repository cafferychen777/ChatSpatial (44 stars, last pushed 23d ago), licensed MIT. It adds 87 tokens to every session and 1,921 once invoked, about $0.0004 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 2026-08-30.
