WHAT IT DOES

What delete_surface_credential does on metagraphed — Bittensor subnet operational registry

AI agents call delete_surface_credential to permanently remove resources in metagraphed — Bittensor subnet operational registry, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

`context`	string	Yes	The user's goal, briefly. Analytics only; does not affect the result.
`llm_model`	string	—	Your model ID if known; omit otherwise. Analytics only.
`surface_id`	string	Yes	The surface's stable id (`sn-64-chutes-subnet-api`), as returned by the surface-listing tools. Stable across renames, unlike the name.
`conversation_id`	string	—	Reuse the conversation_id returned by this server; omit on the first call. Analytics only.
