Six ideas, then one screen per job

Kustos is shaped like the way you already think about your library: what you own, what it looks like, what should go, and who has watched it.

It describes what should be true

Rules are not one-off actions. Kustos keeps them true on a schedule, so a rule catches titles no matter how they arrived.

Nothing deletes on its first run

Cleanup has a safe mode that reports what it would do and removes nothing. When a rule does match something, it enters Leaving Soon with a countdown (7 days unless you change it) before anything is deleted.

Watch data is merged, not picked

Plex, Tautulli, Trakt and Simkl become one picture. One source works; two means a missed scrobble can never drop a show someone is mid-way through.

It only touches what it owns

A tag or label rule only touches the one tag it names — never your own labels, never someone else’s.

One title, one identity

Series that other services split in two are collapsed onto one id, so watch marking, posters and requests all agree. Your override wins.

Order is always stated

Global, then per library, then the collection itself. Artwork you picked by hand is never overwritten by anything scheduled.

• —It reads your real libraries, collections, rules and settings before it writes anything, so what it builds uses fields that actually exist.
• —It says what it is about to change, in one sentence, before it changes it.
• —A cleanup rule it writes arrives switched off unless you ask for it on, and nothing it matches is deleted that day.
• —A Sonarr or Radarr rule it writes starts disabled, with a Preview that is always a dry run.

• —Reading history needs nothing from anyone else — no accounts, no tokens, no setup for the household.
• —Movies work from any single source. Episode-level detail comes from Plex history or Tautulli.
• —Keep protects a title from cleanup absolutely. Rewatch is a one-time do-over that clears itself. Dropped ignores one person’s half-watched state.
• —Hiding someone is display-only: their watch history still counts, so nothing gets deleted out from under them.

• —Status colours at a glance: complete, downloading, upgrade available, missing.
• —Bulk edits run one title at a time on purpose, so one failure never takes the rest with it.
• —Removing a download defaults to the polite option: drop it from the queue, leave the torrent seeding.

• —Your highest-ranked source wins and overwrites the ones below it.
• —A show you enrolled outranks the default for that show.
• —Artwork you picked by hand is never overwritten by anything scheduled.

• —Safe mode reports what a rule would do and deletes nothing; those items show on the dashboard marked as a dry run.
• —Nothing a rule matches is deleted straight away: it enters Leaving Soon with a countdown (7 days unless you change it), and you can keep or remove anything before then.
• —A rule never deletes more than its cap in one pass; anything over waits for the next pass.
• —The exception is Run & delete now, which skips the countdown and deletes straight away. Turn on the Sonarr/Radarr recycle bin if you want deletes to be recoverable.

• —Watchlist requests arrive within minutes, not the next day.
• —Approving one hands it to Sonarr or Radarr with the right profile and folder.
• —Every suggestion carries a one-line reason, because a recommendation you cannot argue with is one you cannot correct.
• —Not now puts a pick aside for later; Never takes it out of consideration for good.

• —Global defaults, then per library, then the collection itself.
• —Already using Kometa? Its asset folders can be imported; overlays are set up again here with switches.
• —Nothing to hand-write — it is all switches and previews.
