SUSPICIOUS: the spreadsheet capabilities are coherent and proportionate, but the skill depends on an undisclosed `recalc.py` script and auto-configured LibreOffice macro that are not included or verifiable here. That missing execution-path provenance creates notable supply-chain risk, though there is no evidence of credential theft, exfiltration, or confirmed malicious intent in the visible skill text.

This module is primarily a LibreOffice headless recalculation wrapper, but it also conditionally writes a LibreOffice Basic macro (Module1.xba) into the user’s LibreOffice profile directory and then invokes it via vnd.sun.star.script. That combination (persistent host modification + Office/LibreOffice macro execution) is a strong security red flag for supply-chain risk because the macro payload can potentially execute arbitrary actions in the LibreOffice process context. The provided fragment is incomplete around macro_content, so the exact payload cannot be verified here; treat this as high-risk and require inspection of the actual macro content and packaging process, ideally in a sandbox.
