extract_json_from_text
Extract and parse a JSON value embedded in messy LLM output. Strips ```json fences, leading/trailing prose, code comments, and tolerates other LLM-isms. Returns the first parseable value and where in the text it started.
parse_partial_json
Parse a JSON string that may be truncated mid-stream (e.g. a partial LLM tool call). Always returns a valid JSON value with synthetic closure of any open strings, arrays, or objects. Reports whether the input represented a complete top-level value, plus the cursor path where parsing stopped.
validate_json
Strict-mode RFC 8259 validator. Returns ok=true and the parsed value if the input is valid JSON; otherwise returns ok=false with a precise byte position and human-readable message.
