## Why remove_spool is rated Critical

Removing a spool from inventory is a destructive operation that deletes or purges a record from the filament inventory. This is likely irreversible (the spool entry is gone), making it Destructive. The blast radius is medium since it affects inventory tracking data but does not directly damage physical hardware or financial systems.

From the tool's own definition: "'Remove a filament spool from inventory' — permanently removes an inventory record"

## Use case

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

## Recommended policy (PolicyLayer)
