Delete all log files except latest.log and debug.log on the Minecraft server.
AI agents call clear_log_files to permanently remove resources in OPanel MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (log files) in bulk, matching the Destructive category definition. While logs can often be regenerated over time, the historical data is permanently lost and cannot be recovered. The severity is high because deletion of audit/historical data could obstruct incident investigation, compliance verification, or system troubleshooting.
From the tool's definition Tool description states 'Delete all log files' - uses 'Delete' verb indicating irreversible removal of data. The tool removes historical log files permanently, which cannot be undone.

clear_log_files is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_log_files rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
