删除表情包。当某个表情包不再需要时使用，会从列表和磁盘中永久删除。
AI agents call delete_meme to permanently remove resources in Meme MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes meme files from disk storage. Even though the blast radius is limited to local meme assets (not critical system data or financial resources), the permanent deletion nature places it in the Destructive category. Severity is high because an agent could autonomously delete valuable user-generated or curated meme collections without recovery options.
From the tool's definition Tool description states it 'will permanently delete' (会从列表和磁盘中永久删除) the meme 'from the list and disk.' The action is irreversible and removes data from persistent storage.
