Undo an install

cprof install backs up everything it replaces, so the last install is reversible. cprof rollback undoes it; cprof rollback --undo re-applies it. It's a strict, all-or-nothing toggle on the most recent install in a scope — not a time machine.

Roll back the last install

cprof rollback

This restores every file the install merged or overwrote from its backup, and moves files the install created into a trash dir (.cprof-trash/<timestamp>/) — never a hard delete. Preview it first with --dry-run.

Re-apply it

Changed your mind? Re-apply the install you just rolled back:

cprof rollback --undo

Rollback stashes the post-install state before reverting, so --undo restores it exactly. The ledger flips between applied and rolled-back each way.

The change-guard

Before touching anything, rollback checks that every recorded file still matches the state it expects. If any file changed since the install, the whole operation aborts and names the offenders (exit 3) — so an edit you've made since installing is never silently clobbered. Override with --force:

cprof rollback --force

Scope

By default rollback acts on the project ledger (.cprof-state.json); use --global to act on the ~/.claude ledger instead.

Exit codes: 0 done · 1 usage · 2 nothing to roll back · 3 aborted (a file changed; use --force). See the rollback reference for the full flag list — and note a cprof new --force from the Scaffold a new project guide is reversible the same way.
