Audit a spreadsheet before trusting it — the error hunt (hardcoded overrides, broken ranges, silent unit mixes), the fragility map (what breaks when rows are added), and the load-bearing-formula review that catches the mistake before the meeting does. Use when asked check this spreadsheet before we present it, why don't these numbers add up, audit this model someone left behind, or is this sheet safe to build on. Produces the findings ranked by damage, the fragility map, the verified-vs-suspect ledger, and the fix list.

From the source SKILL.md

Spreadsheets fail silently: the SUM that stops at row 40 while data runs to 60, the hardcoded 1.1 someone typed over a formula in March, the column that's monthly in one section and annual in another. The sheet still displays numbers — wrong ones, confidently. This skill audits the way inherited models deserve: hunt the classic error classes, map what breaks when the sheet grows, and rank findings by damage-if-wrong — because the audit's job is protecting the decision the sheet feeds, not achieving cosmetic tidiness.

What this skill does

Spreadsheet Audit is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/spreadsheet-audit/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked check this spreadsheet before we present it, why don't these numbers add up, audit this model someone left behind, or is this sheet safe to build on. Produces the findings ranked by damage, the fragility map, the verified-vs-suspect ledger, and the fix list.
