Can I use this for standard SQL versioning?

Yes, while it includes advanced topological features, the skill provides standard SQL macros and patterns for implementing robust versioning and auditing in any DuckDB-compatible environment.

What is a bi-temporal schema pattern?

A bi-temporal schema tracks two different timelines: the 'Valid Time' (when an event actually happened in the real world) and the 'Transaction Time' (when the data was actually recorded in the database).

What is DuckDB time travel?

DuckDB time travel refers to the capability of querying a database table at a specific historical point in time or a specific snapshot version, allowing developers to see the data state exactly as it existed previously.

How does interaction color tracking work in this skill?

It uses the Gay.jl SplitMix64 algorithm to assign a deterministic hex color to every thread interaction. This creates a visual and mathematical lineage for queries, helping track the 'causality' of data changes.

データベース管理

Facilitates advanced temporal versioning and causality tracking within DuckDB using time-travel queries and deterministic interaction coloring.

概要

Duck Time Travel is a specialized Claude Code skill designed for developers and data scientists working with DuckDB and DuckLake environments. It enables precise querying of historical data states through snapshot versions and timestamps, while integrating a unique deterministic coloring system for tracking thread lineage and interaction causality. By implementing bi-temporal schema patterns and GF(3) conservation principles, it ensures data integrity and provides a clear audit trail for complex, evolving datasets, making it ideal for debugging regressions or maintaining historical records in analytical workflows.
