tooluniverse-data-wrangling

Universal data access patterns for downloading and parsing scientific data when ToolUniverse tools don't cover the source, only return metadata, or you need bulk records. Use for VCF/h5ad/BAM/SDF/GCT parsing, multi-step API workflows (search to filter to download to parse), thousands of records at once, or sources with no dedicated tool. Write Python code via Bash for every step.

# Data Wrangling: Universal Access Patterns

Reference for downloading and parsing scientific data from any source. Write and run Python code via Bash for every step.

## When to Use

- ToolUniverse tool returned metadata/search results but you need **raw or bulk data**
- Data is in a format tools don't parse (VCF, h5ad, BAM, SDF, GCT)
- You need a **multi-step API workflow** (search -> filter -> download -> parse)
- The data source has **no ToolUniverse tool** at all
- You need **thousands of records**, not the 10-100 a tool returns

## Decision: Tool vs Code
