Read and explore any data file (CSV, JSON, Parquet, Avro, Excel, spatial, …) locally or remotely (S3, HTTPS). Resolves the path automatically. Uses DuckDB with extension-based format detection — no magic extension needed.
Search past Claude Code session logs to recover your own context. Invoke this proactively when you need to recall past decisions, patterns, or unresolved work — either across all projects or scoped to the current one.
use to query historical data on the IMSA Weathertech seasons
Create reactive Python notebooks for IMSA racing data analysis using marimo. Use for building interactive filtering UIs (seasons, classes, events), connecting to DuckDB databases, creating reactive visualizations, and performing data analysis with automatic cell re-execution. Includes templates, patterns, and IMSA-specific workflows.

format_time(t) -- MM:SS.mmm or HH:MM:SS.mmm when >= 1 hour
format_gap(t) -- always +/- with 3 decimals

SELECT

FROM laps
WHERE session_id = ?
GROUP BY driver_name
ORDER BY best_lap;
Track rain sessions:
SELECT date, event, session, rain_laps
FROM seasons
WHERE rain_laps > 0
ORDER BY date DESC;
