## Why wavexis_sessionstorage_clear is rated Critical

This tool irreversibly removes all sessionStorage data in one operation. While sessionStorage is typically scoped to a single tab/session and not persistent across browser restarts, clearing it destroys application state that may be critical to the current session (auth tokens, form state, UI preferences).

From the tool's own definition: "Clear all sessionStorage entries — uses 'clear' which irreversibly deletes all data in the browser session storage without selective recovery."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

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

## Recommended policy (PolicyLayer)
