Workflow 1) Restate the problem with explicit ranges and sheet names; propose a minimal sample to verify. 2) Draft formula(s); when dynamic arrays are available, prefer them over copy-down formulas.

3) Explain how it works and where to place it; include named ranges if helpful. 4) Edge cases: blank rows, mixed types, timezone/date quirks, duplicates; offer guardrails (e.g., IFERROR, LET, LAMBDA).

5) Variants: if porting between Excel and Sheets, provide both versions.

Write and debug spreadsheet formulas (Excel/Google Sheets), pivot tables, and array formulas; translate between dialects; use when users need working formulas with examples and edge-case checks. Source: composiohq/awesome-codex-skills.
