Use when generating Sankey or alluvial plots from sample annotation tables where rows are samples and selected columns are categorical stages such as risk group, response status, subtype, or cohort labels. NOT for: gene network flow analysis, continuous-value trajectories, or graph-structured pathway visualization.

# Sample Group Sankey Plot

Builds a reproducible Sankey/alluvial visualization from a tabular sample annotation file and exports the selected annotations, lodes-format table, plot PDF, and session metadata.

## Input Validation

This skill accepts: a sample annotation table in CSV or TSV format where rows are samples and selected columns are categorical stages (e.g., risk group, response status, subtype, cohort label). At least 2 stage columns are required.

If the user's request does not involve generating a Sankey or alluvial flow diagram from categorical sample annotations — for example, asking to visualize a gene regulatory network, plot continuous-value trajectories, analyze pathway flow, or process non-tabular data — do not proceed with the workflow. Instead respond:

> "sample-group-sankey-plot is designed to generate Sankey/alluvial plots from categorical sample annotation tables. Your request appears to be outside this scope. Please provide a sample annotation table with at least 2 categorical stage columns, or use a more appropriate tool for gene network visualization or pathway analysis."

**Readability guidance:** Sankey plots are recommended for fewer than 8 unique values per stage and fewer than 5 stages total. For larger inputs, filter or aggregate categories before plotting to ensure readable output.
