CBT Labs is where we share the tools, apps, bots, and scripts we actually use and build. Some are for clients, some are for fun, all of them solve a real problem.

DISCORD BOTS
AYIN
Always watching. Ayin is a media library monitoring bot running on a Raspberry Pi. Check disk space, active library tasks, temperature alerts and make media requests right from Discord. Dry, observant, and not particularly impressed by anything. Designed around the Watcher from Horizon Zero Dawn.

DEPUTY
Law and order on the frontier. Deputy runs The Ocho, a Minecraft Bedrock frontier realm, and takes the job seriously. Onboarding, PvP tracking, bounties, lore submissions, voice ambience, POI maps and weekly awards. Friendly until you break the rules. He has a ledger and everyone is in it.

PLEX LIBRARY JUNK CLEANUP
Runs daily and scans the Plex media directories for files that are misnamed, improperly tagged, or not catalog-ready. Builds a delete list, executes it, and posts a cleanup report to Discord. Posts an all-clear if nothing needs attention.

● Live – HTPC
60 DAY UNWATCHED MEDIA CLEANUP
Nightly library maintenance. Pulls watch history from Plex, flags anything unwatched for 60 days or more, evaluates TV seasons episode by episode before touching anything, removes stale media, refreshes the library, and posts a full report to Discord via Ayin. Has a heads-up warning path for media approaching the threshold.

MORE IN PROGRESS
More client and internal automations in the works. If a task is repetitive and has clear rules it will probably get automated eventually.
