skill-disposable-artifact-cleanup

Run an audit first to establish each artifact's exact path, producing task, and retention dependencies. Direct cleanup then requires explicit authorization and removes only the approved exact files or task-owned directories, never shared roots.

Git worktree cleanup is delegated, not performed directly. Route the worktree to the branch-finishing workflow after verified Git disposition, then use native cleanup or git worktree remove; never recursively delete the worktree directory.

Untracked paths are review candidates only until producer ownership is proven. Filename similarity, age, or Git ignore status does not establish ownership, so uncertain paths must be preserved.

Preserve tracked and staged files, user data, credentials, environment files, databases, backups, uploads, normal profiles, and anything needed for active verification, debugging, recovery, or handoff. Nested repositories and unresolved symlinks are also protected.

A candidate is preserved when ownership evidence is missing, stale, or uncertain, or when retention dependencies still exist. Recovery requires re-establishing exact identity, producer, owner, and cleanup authority through the current plan or a validated handoff.
