@arizeai/phoenix-client@7.6.0
Minor Changes
-
d328c3e: Add a
deletePrompthelper to thepromptssubpath. It takes apromptselector —{ name }or{ promptId }— matching the selector stylegetPromptalready uses, and callsDELETE /v1/prompts/{prompt_identifier}(Phoenix server >= 13.20.0). Version-level selectors ({ versionId },{ name, tag }) are rejected rather than widened to the whole prompt. Deletion cascades to every version of the prompt along with its version tags and labels.Also exports a
PromptIdentifiertype fromtypes/promptsfor the prompt-level selector union.
