What clear_buffer does on Proxypin

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

Why clear_buffer needs a policy

This tool permanently deletes buffered network traffic without recovery mechanism or undo capability. While the data loss is scoped to in-memory buffers rather than persistent storage, the action is non-reversible and could result in loss of important captured request/response data that an AI agent might need for analysis.

From the tool's definition Tool name 'clear_buffer' and description 'Clear all captured requests from the buffer' indicates irreversible deletion of captured HTTP traffic data.
