outputguard Stop wrestling with broken LLM structured output. Validate, repair, and retry — automatically. The Problem LLMs produce broken structured output constantly. JSON is the common case, but models also return YAML, TOML, Python-style literals when forced JSON is off, markdown fences, comments, trailing commas, , truncated objects, and helpful commentary around the data you asked for. Every AI application ends up writing the same brittle parser + + regex gauntlet.
