Individual skill
forgiveness-undo-and-soft-delete
Use this skill when designing reversibility — undo systems, soft delete, archive-with-recovery, version history, "Undo Send" patterns, and any mechanism that lets a user step back from an action they regret. Trigger when designing destructive actions you want to be safe rather than friction-heavy, when picking between confirmation dialogs and undo toasts, when defining recovery windows, or when planning version-history features. Sub-aspect of `forgiveness`; read that first.

# Forgiveness through reversibility
Reversibility is the highest-leverage form of forgiveness short of structural prevention. It makes destructive actions safe by allowing recovery — users keep speed (no friction up front) and safety (the action is undoable). Whenever an action *can* be made reversible, that's almost always preferable to confirming it.
## The reversibility ladder
Different actions need different reversibility approaches:
### Synchronous undo (Cmd-Z)
The classic. The user takes an action; pressing Cmd-Z (or Ctrl-Z) reverses it. Multi-level undo lets the user back out through a sequence of actions.
**When it applies:** editing operations on a single object — text editing, image manipulation, design tool actions, code edits.
