Delete one artifact from a repo by its id (get ids from prompthub_get_repo
AI agents call prompthub_delete_artifact 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.
The tool permanently removes data (an artifact) from a repository without the ability to undo the action. This matches the Destructive category definition. While the blast radius is somewhat limited to a single artifact rather than an entire repo, deletion is still irreversible and represents a significant integrity risk if an AI agent were to misuse it (e.g., deleting critical prompts unintentionally).
From the tool's definition Tool name contains 'delete' and description states 'Delete one artifact from a repo by its id' — this is an irreversible deletion operation.
