spreadsheet-audit
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.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Spreadsheet Audit Skill 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 Produces - **The findings, ranked by damage** — each: location, what's wrong, what it's currently mis-stating - **The fragility map** — the formulas that break on the next added row/column, before they do - **The verified/suspect ledger** — which outputs were traced clean and which remain unverified (unverified ≠ wrong; the label is the honesty) - **The fix list** — ordered, with the make-it-robust upgrades (structured ranges, input isolation) where they matter ## Required Inputs Ask for these if not provided: - **The sheet** — the file, or its formulas/structure described; audits work on the actual formulas, not the values

What does the spreadsheet-audit skill do?
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.

How do I install it?
Run `npx skills add mohitagw15856/pm-claude-skills --skill spreadsheet-audit --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mohitagw15856/pm-claude-skills, a repository with 1,255 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
