About this skill

Safe delete

There are three kinds of reset. Pick the mildest one that does the job.

  1. Undo recent changes. Run ddev snapshot restore --latest, or ddev snapshot restore <name> for a named snapshot. The agent may run this itself.
  2. A fresh install that keeps config. Use the backend-setup skill. Do this only on a site made from the vibe-config-backend template, and only after a snapshot. Tell the person that content will be lost. This skill carries no fresh-install command of its own. Never delete the project to get a fresh install.
  3. Delete the DDEV project. This is only the person's, through the delete script, skills/safe-delete/scripts/safe-delete.sh in this repository.

On any other site, offer only the restore and the delete.

What a snapshot covers

A snapshot covers the database only. It does not cover sites/default/files, code or exported config. Say so before the person relies on one.

Hard rules

  • The agent never runs ddev delete and never runs the script itself.
  • The agent never fakes a terminal (a pseudo-terminal, script, piped input) to get past the script's confirmation. The script refuses without a real terminal on purpose.
  • The agent hands the person the exact command to run in their own terminal. Before handing it over, the agent replaces the script path with its absolute path on this machine, because the person runs it from the DDEV project folder:
skills/safe-delete/scripts/safe-delete.sh [--no-snapshot] [--remove-folder PATH] PROJECT

The script prints what it will delete, asks the person to type the project name, takes a snapshot, then deletes. Exit 0 means deleted. Exit 2 means a usage error, no terminal, a wrong name or a refused folder. Exit 1 means a ddev call failed.

Warning: a snapshot named seed comes back

A snapshot named seed reloads on the next start of a project with the same name. After a delete and a restart under that name, the seed data returns instead of an empty or fresh site. On a restart with an empty database, a snapshot named seed loads instead of a fresh install. Tell the person before they delete.
