Semantic Difference Comparator

This tool compares two text inputs semantically, returning a similarity score between 0 and 1, a list of key semantic differences, and a concise summary describing how the texts relate. It accepts two required string parameters: text_a (first text to compare) and text_b (second text to compare). The worker LLM must use only these inputs and any provided payloads when reasoning, and must produce an output that strictly validates against the system-provided structured output schema (auto-produced, not supplied here), with no extra keys and correct types for all fields.
