Function parse_tools_value

ds4_server.c:1566–1609

OpenAI wraps tools as {"type":"function","function":{...}}. Anthropic sends * the function schema directly as {"name":...,"input_schema":...}. The DS4 * prompt wants one raw function schema per line, so unwrap OpenAI tools and keep * already-direct schemas unchanged. Responses can additionally group tools in a * namespace item; those are flattened for DSML prompt rendering while preserving *
