bio-pathway-wikipathways
WikiPathways enrichment using clusterProfiler and rWikiPathways. Use when analyzing gene lists against community-curated open-source pathways. Performs over-representation analysis and GSEA for 30+ species.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# WikiPathways Enrichment ## Core Pattern - Over-Representation Analysis ```r library(clusterProfiler) library(org.Hs.eg.db) wp_result <- enrichWP( gene = entrez_ids, # Character vector of Entrez IDs organism = 'Homo sapiens', # Full species name pvalueCutoff = 0.05, pAdjustMethod = 'BH' ) head(as.data.frame(wp_result)) ``` ## Prepare Gene List ```r de_results <- read.csv('de_results.csv') sig_genes <- de_results[de_results$padj < 0.05 & abs(de_results$log2FoldChange) > 1, 'gene_symbol'] gene_ids <- bitr(sig_genes, fromType = 'SYMBOL', toType = 'ENTREZID', OrgDb = org.Hs.eg.db) entrez_ids <- gene_ids$ENTREZID ``` ## GSEA on WikiPathways ```r # Create ranked gene list gene_list <- de_results$log2FoldChange names(gene_list) <- de_results$entrez_id gene_list <- sort(gene_list, decreasing = TRUE) gsea_wp <- gseWP( geneList = gene_list, organism = 'Homo sapiens', pvalueCutoff = 0.05, pAdjustMethod = 'BH' ) head(as.data.frame(gsea_wp)) ``` ## With Background Universe ```r all_genes <- de_results$entrez_id wp_result <- enrichWP( gene = entrez_ids, universe = all_genes, organism = 'Homo sapiens', pvalueCutoff = 0.05 ) ``` ## Make Results Readable ```r # Convert Entrez IDs to gene symbols w

What does the bio-pathway-wikipathways skill do?
WikiPathways enrichment using clusterProfiler and rWikiPathways. Use when analyzing gene lists against community-curated open-source pathways. Performs over-representation analysis and GSEA for 30+ species.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill wikipathways-gptomics-bioskills --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
