class klea_utils.errors.LLMInvocationErrorCategory(*values)

Bases: str, Enum

Classification of LLM invocation failures.

Providers report errors inconsistently, so the classification is a best-effort heuristic driven by tolerant regex matching (see klea_utils.llm.classify_llm_invocation_error). The category drives retry behaviour in the LLM nodes: some categories are retried with adjusted parameters, others surface immediately.
