## Why browser_mutations_clear is rated Critical

Clearing captured DOM mutations is an irreversible action that destroys recorded observation data. While it doesn't delete files or external data, the captured mutation history cannot be recovered once cleared, making it Destructive. Severity is medium since it affects in-memory/session data rather than persistent storage.

From the tool's own definition: "'Clear all captured DOM mutations' — permanently removes/clears recorded mutation data"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

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