Do NOT use for API documentation (use `api-documentation`), user guides (use `user-guide`), or changelogs (use `changelog-writing`).

Use when the user needs to clean data using spreadsheet formulas rather than external tools. Do NOT use for a full data cleaning protocol across any tool (use data-cleaning-protocol), setting up validation rules (use data-validation-setup), or auditing a spreadsheet model (use spreadsheet-model-audit).
Audits a spreadsheet model for quality and reliability. Checks formula consistency, hardcoded values in formulas, circular references, missing error handling, and documentation gaps. Produces an audit report with specific remediation steps. Use when the user needs to verify the integrity of a spreadsheet model before relying on its outputs for decisions. Do NOT use for data cleaning (use spreadsheet-data-cleaning), setting up validation rules (use data-validation-setup), or building new financial models (use financial-model-template).
Advanced Excel and Google Sheets mastery covering lookup functions, pivot tables, conditional formatting, macros and Apps Script, data validation, dashboard creation, and financial modeling techniques for business analysis.

Use when the user asks about technical documentation, technical documentation configuration, or documentation best practices for technical projects. Do NOT use when the user needs a different developer tools capability -- check sibling skills in the developer tools subcategory.
