Processes and analyzes data with resident-kernel engines (DuckDB, Polars) and one-shot tools. Use for CSV/parquet/JSON analysis, group-by/join/aggregation, time series, distributions, cleaning, or plotting a dataset.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Scientist: Hybrid-Engine Data Processing Answer data questions through the cheapest engine and surface that can prove the answer, and decide where the computation should live before touching the data. ## Execution surfaces: resident kernel first A persistent REPL/eval kernel (many harnesses expose one for JavaScript and Python) is the default surface. Reason: each one-shot process pays roughly a second of spawn-plus-import overhead and re-scans the input file, while a resident connection amortizes both — after a one-time load, repeat queries return in milliseconds. Exploration is repeat queries, so this difference dominates the session. 1. **JavaScript kernel (Bun)**: run `scripts/ensure-js-deps.sh` once; it prints the absolute import path for `@duckdb/node-api`. Dynamic-import it, connect once, query across cells. 2. **Python kernel**: the default surface for Python work. duckdb/numpy/matplotlib are typically resident; Polars and pyarrow come from `scripts/ensure-py-deps.sh`, which installs them once into a user cache keyed to the kernel's interpreter — `sys.path.insert` the printed directory and import. The interpreter itself is never mutated. …

How to install
mdr add code-yeongyu/oh-my-openagent/data-scientist@sha256:f6be015d7fe60707The line at the top of this page pins the label git:20261106.7ff3b56, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
