remove_spell
AI agents call remove_spell to permanently remove resources in DM20 Protocol — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The name 'remove_spell' strongly suggests irreversible removal/deletion of a spell entry from a character sheet or game record. Given sibling tools like 'add_spell' (its logical counterpart), this tool likely deletes spell data. Empty description lowers confidence. Severity is medium as the blast radius is limited to in-game campaign data, though it could be disruptive if a character's spells are deleted erroneously.
From the tool's definition Tool name 'remove_spell' implies deletion of a spell from a character or game entity. Description is empty and uninformative.
