Production use case: data teams need read-only agents that can inspect pipelines, query governed datasets, and recommend next actions when metrics break.

This project uses Nebius through LangChain with a guarded SQLite query tool. The agent can inspect schema, run read-only SQL, correlate pipeline changes, and produce an incident-style data quality report.

Run

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
cp .env.example .env
# add NEBIUS_API_KEY
python main.py

Production Pattern Demonstrated

Read-only SQL guardrails
Schema discovery before analysis
Pipeline-change correlation
Typed data quality report
SQL/audit trail for reproducibility
