What it does

Debugs broken Excel formulas.

Use when an Excel formula shows an error, when the spreadsheet is slow, or when a formula returns the wrong value.

How it arrives

You don't install skills one by one. ClevskillSetup installs the whole curated pack, wires the safety hooks, and verifies each skill actually runs on your machine. The weekly health scan re-checks it from then on, and repairs route through your approval.

Setup

No setup needed. It works as soon as the pack is installed; no accounts, no API keys, nothing leaves your machine.

Invoke it

In Claude Code or Claude Cowork, just ask in plain language; skills trigger on intent. Things people say that make this skill run:

you: fix this excel formula
you: debug formula
you: why is this cell #NAME
claude: [excel-formula-debugger runs, result returned with full audit log]

A documents-and-data tool: it works on your files locally and writes results to new files, never over your originals.
