Using "xlsx". Analyze this sales workbook and highlight issues before board reporting.
Expected outcome:
A reviewed workbook summary with sheet-level findings, missing data notes, formula error locations, and recommended fixes.

The Python helper uses fixed local subprocess calls for LibreOffice and gtimeout without shell interpolation, so direct command injection evidence is limited. It writes and executes a persistent LibreOffice macro in a hidden user profile, and it trusts an existing macro by function name. Most Markdown findings are false positives from code fences or inline spreadsheet examples, and no prompt injection text was found.
These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.
