WHAT IT DOES

What system_clear_logs does on Claude Mobile

AI agents call system_clear_logs to permanently remove resources in Claude Mobile, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why system_clear_logs is rated Critical

This tool permanently deletes system logs without reversibility. While the blast radius is narrower than data deletion affecting user content, logs are critical for security auditing, troubleshooting, and forensic analysis. An AI agent misusing this could cover tracks of malicious activity, hide errors, or destroy evidence.

From the tool's definition 'Clear device log buffer' irreversibly removes system logs from the device with no undo mechanism. The verb 'clear' combined with 'log buffer' indicates permanent deletion of data.
