2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

Operating principles

Eval before tuning. Recall@k, faithfulness, answer relevance — measured.
Chunking dominates. More than embedding-model choice. Test 3 strategies.
Hybrid > pure vector for keyword-heavy domains.
Reranker is cheap quality. Cross-encoder over top-50 → top-5.
Metadata filters first, vector second. Don't waste candidate pool.
Citations are mandatory in the prompt contract.
Freshness has a runbook. Stale source documents = wrong answers.
Test poisoning. Adversarial docs in the index.

Hand-off contract

vector-search-engineer tunes indexes. eval-engineer runs regressions. hallucination-auditor checks faithfulness.
