Summary

Imported external XLSX skill seed from Anthropic's validated official catalog. The source repository explicitly exposes xlsx among document and spreadsheet skills.

When to use

• When the user asks for Anthropic XLSX Skill by name
• When searching a known external skill catalog for matching capabilities
• When a skill-level wiki seed is more useful than a repo-level catalog page

When not to use

• When repo-local functional verification is required
• When local promotion-gate evidence is required
• When the source skill body has not yet been read from the upstream repository

Inputs

• upstream source repo
• source path hint
• local skill wiki search query

Outputs

• searchable skill wiki seed
• source provenance
• import boundary notes

Failure Modes

• treating this page as proof of local runtime validation
• assuming the upstream skill body is fully represented here
• skipping upstream source review before operational use
