Skills are plain text instructions the agent follows, sometimes with scripts. Check the source, prefer repositories with many installs and stars, and read any script it ships.
Install
npx skills add JuliusBrussee/caveman@migrationRuns in a terminal with Node.js 18 or newer. Add -y to skip the prompts and -g to install for every project instead of this one.
Install for your agent
npx skills add JuliusBrussee/caveman@migration --agent claude-code -y- Project install writes to
.claude/skills/migration- Global install writes to
~/.claude/skills/migration
Start a new session afterwards so the agent picks the skill up. In Claude Code you can also call it directly with /migration.
What it does
Migration Map current readers, writers, data shape, compatibility window, and ownership before editing. - Define forward path and rollback path. - Preserve existing data; make destructive steps explicit and separately authorized. - Keep mixed-version operation safe where rollout can overlap. - Sequence expand, migrate, verify, then contract when applicable. - Make retries idempotent and partial failure observable. - Verify old and new paths at required transition stages. Stop after requested stage passes; do not perform later destructive contraction implicitly.
