Install Migration

Pick your agent. Every command is ready to paste.

$npx skills add JuliusBrussee/caveman --skill migration

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads migration when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the migration skill”. In Codex, type $migration.

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.

Tips for Migration

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 22 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
