brand-xlsx

Use this skill when the user wants reusable branded Excel/workbook generation from a company .xlsx template and variable user-provided data.

This is an AI-agent skill for Codex and Claude Code. The user should describe the workbook/model they want filled; the agent maps that request to named cells and named regions, invokes the internal Python engine, verifies the output, and returns the generated .xlsx.

The seven verbs: three deterministic + four model-assisted

Every brand skill (brand-docx, brand-pptx, brand-xlsx) implements the same contract. The deterministic core is extract / verify / generate; on top of it sit the optional learning verbs comprehend / learn / propose-overrides / refine, each fail-closed (the engine validates every proposal and authors every value).
