Retention

librarium cleanup --dry-run

runs.keep_days defaults to unset. Preview retention before deleting completed Runs. Keep stored progress while research is in progress; removing it does not cancel upstream work. Your application owns privacy and retention policy.

Upgrade

librarium upgrade
librarium --version

Upgrade follows an existing installation channel. Preserve config backups and follow v1 migration.

Completions and skill

librarium completions zsh
librarium install-skill --force

Skill installation uses the exact bundled instructions without a provider call. It does not upgrade the CLI. Review a forced replacement of existing local skill text before applying it. Amp global skill publication is separate from a local installer.
