MIT-licensed Chinese-language NL2SQL agent for business intelligence with business-term normalization, deterministic schema linking, SQLGlot validation, risk scoring, read-only execution, result auditing and bounded self-correction.
Verified 2026-09-17. Repository reports 219 tests and a 41-question evaluation over a generated 24-table/~87k-row enterprise dataset. A deterministic schema-selection evaluation found rule scoring at 1.000 recall/full hit versus vector retrieval at 0.9634 recall/0.9268 full hit. Switching the default to rules, with model and prompt unchanged, reportedly moved SQL validity 0.951→1.000, execution accuracy 0.927→0.976 and result accuracy 0.610→0.707; 4 cases changed wrong→right and none right→wrong. Still a young single-maintainer prototype with 0 stars/forks and no tagged release; reported numbers are maintainer-run on a synthetic dataset.
