Delete one repo you own by owner/name. This permanently removes the repo rows and asks PromptHub to clean stored artifact/reference objects. A 404 means the repo does not exist or you cannot access it.
AI agents call prompthub_delete_repo to permanently remove resources in Prompthub — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes an entire repository and its associated artifacts/references, which cannot be undone. This is a destructive operation affecting potentially significant data. The severity is high because an AI agent accidentally calling this tool could permanently lose user-owned prompt repositories and their contents.
From the tool's definition Description explicitly states 'permanently removes the repo rows' and 'Delete one repo'. The tool name contains 'delete' and the description emphasizes irreversible deletion ('permanently removes').
