Quick brief

Tool: csvlens. This skill gives an agent a focused data-triage job: open a large CSV quickly, inspect columns and rows interactively, and identify what needs cleaning or mapping before deeper processing starts.

How it works

What this skill actually does

When to use it: invoke this when the hard part is understanding the shape of a CSV export before writing transforms, joins, or cleanup logic. Using this skill is different from using the product normally because the workflow is a preflight checkpoint: inspect the file, verify schema assumptions, spot anomalies, and then hand off a cleaner downstream transformation plan.

Scope boundary: this is not a generic spreadsheet viewer listing and not a broad CSV processing toolkit card. Its boundary is specific: interactive inspection and triage of large CSV files with csvlens before heavier data work begins.
