Audit and optimize Claude Code configuration with dynamic best-practice research
Use when the user wants stable structured fields, required keys, reliable machine-readable sections, or downstream-consumable output from one model request, including `.output(...)`, field ordering, and `ensure_keys`.
Production-ready single-cell and expression matrix analysis using scanpy, anndata, and scipy. Performs scRNA-seq QC, normalization, PCA, UMAP, Leiden/Louvain clustering, differential expression (Wilcoxon, t-test, DESeq2), cell type annotation, per-cell-type statistical analysis, gene-expression correlation, batch correction (Harmony), trajectory inference, and cell-cell communication analysis. NEW: Analyzes ligand-receptor interactions between cell types using OmniPath (CellPhoneDB, CellChatDB), scores communication strength, identifies signaling cascades, and handles multi-subunit receptor complexes. Integrates with ToolUniverse gene annotation tools (HPA, Ensembl, MyGene, UniProt) and enrichment tools (gseapy, PANTHER, STRING). Supports h5ad, 10X, CSV/TSV count matrices, and pre-annotated datasets. Use when analyzing single-cell RNA-seq data, studying cell-cell interactions, performing cell type differential expression, computing gene-expression correlations by cell type, analyzing tumor-immune communication, or answering questions about scRNA-seq datasets.
Fundamental Perforce operations including sync, edit, add, delete, submit, revert, and file state management.
Fully autonomous research pipeline that turns a topic idea into a complete academic paper with real citations, experiments, and conference-ready LaTeX.

Worktree-native merge engineer — git worktree lifecycle, isolated merges and conflict resolution, worktree path conventions, parallel worktree operations, and cleanup automation. Invoke via /git-merge-expert-worktree or when user says "merge in worktree", "isolated merge", "worktree merge".
Manage editorial content pipeline through 6 stages: Ideas, Outlined, Drafted, Editing, Ready, Published. Use when user wants to view pipeline status, add ideas, move content between stages, schedule posts, or archive published content. Use for "content calendar", "pipeline status", "add idea", "schedule post", or "move to drafted". Do NOT use for creating Hugo content files, deploying posts, or modifying site configuration.
