+**Triggered When**: The Seeker has searched every eligible item on an instance once. See [cycles](../seeker#proactive-search).
+
+The notification shows:
+- the instance
+- how long the cycle took
+- how many searches it triggered
+- how many of those searches grabbed a release
+- how many of those grabs were upgrades, from the quality cutoff or the custom format score
+
+**The numbers are a snapshot.** This notification is sent as soon as the last search of the cycle is triggered. It does not wait for that search to finish. The *arr may still be searching, and the Seeker checks the queue for grabs for up to 30 minutes after each search. Grabs that show up after the notification are missing from its numbers. The Searches tab shows the final numbers.
+
+**You get one notification per cycle.** After a cycle completes, the next one waits for the Min Cycle Time. If new items show up during that wait, such as an episode that just aired or a movie you just added, the Seeker searches them as part of the same current cycle. The cycle then completes again, but you are not notified again.

 The Searches tab shows per instance how many items the current cycle searched, how many are left, how long it has been running and how long the previous cycle took. Items in the download queue are not counted as left. Dry run tracks its own cycles and never moves the live one.
 
+To get notified when a cycle completes, turn on [Seeker Cycle Completed](../notifications#seeker-cycle-completed) on a notification provider.

 **Reset cycle** on an instance card closes the current cycle and starts a new one right away, so every eligible item can be searched again. It skips the minimum cycle time once. The button stays disabled until the cycle has searched something. With dry run on, it resets the dry run cycle.
 
 Each Sonarr search event records a content kind: `Standard` (a regular season), `Daily` (a daily series season), `Anime` (an anime season or episode) or `Special` (an episode from season 0). Radarr and replacement searches carry none. The Searches tab can filter events by content kind.
