Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install headless-xlsx-workbook-generation

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent writes a Python script with openpyxl to build sheets, formats and formulas, then saves the workbook to an output folder. You get a .xlsx file that follows the spreadsheet audit conventions.
