Real jobs people get done with AI agents, each tied to its original source, an honest outcome label, a prompt you can edit, and the GitHub repositories involved.
Agent Mode in Excel plans formulas, sheets and charts from a prompt, checks and fixes its own results, and reports its validation steps; Microsoft reports 57.2% accuracy on SpreadsheetBench in its own evaluation.
Install Anthropic's xlsx skill in Claude Code so the agent writes live formulas, recalculates the workbook with LibreOffice and checks it for formula errors.
