llm_output¶

LLM output post-processing utilities.

Reusable helpers for cleaning and extracting structured data from raw LLM text responses.

prompt_risk.llm_output.extract_json(text: str) → Any[source]¶

Extract and parse a single JSON object from raw LLM response text.

Assumes the LLM output contains exactly one JSON value — either bare or wrapped in a single markdown code fence (` `json … ` ` or ` ` … ` `). If a code fence is present, only its content is parsed; any text outside the fence is ignored. If no fence is found, the entire text is treated as JSON.

This function does not handle multiple JSON values in a single response. If the LLM returns more than one JSON block, only the first fenced block (or the full text when unfenced) is considered.

Parameters¶

text:: Raw LLM response text, potentially wrapped in markdown code fences.

Returns¶

Any: The parsed JSON value (typically a dict or list).

Raises¶

JsonExtractionError: If the extracted text is not valid JSON. The exception carries the full raw LLM output (raw_output attribute) and the original parse error as __cause__ for downstream inspection.
