describe_table

Full structural + semantic dump of one table — every column, FK graph, descriptions.

Layer: Physical schema

Full structural and semantic dump of one table. Includes every column (data type, nullability, default, primary-key flag, LLM description), plus all foreign keys with target tables already pre-joined as schema.table.

Pass qualified_name as schema.name — e.g. "public.orders". A bare "orders" raises a clear error pointing you at find_relevant_tables to find the schema.
