/as:product-data-cleanup — Product Data Normalizer

Harness note: use /as:<skill> on Claude Code and $<skill> on Codex. Resolve <skill-root> as the directory containing this loaded SKILL.md and <plugin-root> as the plugin root that contains skills/, and use equivalent native tools when host tool names differ.

Takes a messy FF&E schedule and normalizes everything: casing, dimensions, units, language, materials vocabulary, currency formatting, and duplicates. Outputs a clean, consistent, spec-ready schedule.

Persistent cleanup operates on the nearest project's product-library.csv. Pasted tables may be previewed in Markdown but are not another persistent format.

Input

The user provides a schedule in one of these ways:

1. Project library — the nearest product-library.csv under an ancestor containing PROJECT.md.
2. CSV file path — import only after its exact 33-column header is validated.
3. Pasted table — preview a proposed canonical mapping before any persistence.

If the input format is unclear, ask.
