Database Archival System Skill for Verifying Historical Rows

Select archival candidates by date and state, then verify keys and boundaries in a disposable database.

Install in Claude Code

Use a local fixture database, synthetic order history, and an explicit cutoff date.

Get the complete `plugins/database/database-archival-system/skills/archiving-databases` directory from the pinned GitHub commit.
Copy it into the target project's `.claude/skills/`. Check `.claude/skills/archiving-databases/SKILL.md`, start Claude Code at the project root, and call `/archiving-databases`.

Example task

Archive only closed rows before 2025-01-01. Seed a closed older row, an open older row, and a closed row on the cutoff. Copy candidates into a test archive.

What to check

The archive contains only the older closed row. The report preserves all three source checks and the date boundary.

Frequently asked question

Are matching source and archive counts enough?

Compare keys and representative fields as well. Equal counts can hide the wrong rows.
