Excel Spreadsheet Cellcog

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward CellCog spreadsheet-generation guide, but users should remember that prompts and any data they provide may be sent to CellCog.

Install only if you are comfortable using CellCog as an external service. Avoid putting secrets, regulated data, or confidential financial, employee, or customer details into prompts or attached files unless your organization approves that use.

Missing User Warnings

Finding
The skill instructs users to send prompts and spreadsheet-generation tasks to the external CellCog service but does not clearly disclose that workbook content, prompts, and potentially sensitive business or financial data will leave the local environment. Because this skill is explicitly positioned for budgets, financial models, sales trackers, and employee/business data, users may unknowingly transmit confidential information to a third party.
