xlsx-code-mode

The skill presents a coherent, purpose-aligned tool for server-side Excel workbook interaction with sandboxed execution. Its footprint is proportionate to its stated purpose, and data flows remain local to the server session with explicit persistence controls. No credential handling, exfiltration, or supply-chain risks are evident from the description. Overall, the skill appears benign with respect to security posture, though the involvement of server-side code execution warrants standard caution and access control in deployment.
