# YouTube growth loop — one autonomous tick Growth skills are **split per platform** (same skeleton as grow-threads: plan = standing authorization · tick ≠ publish · idempotent state). State paths are scoped under `growth/youtube/`. ``` /social-flow:grow-youtube <channel> init # once — fix the plan (HITL) /loop 1h /social-flow:grow-youtube <channel> # resting cadence /loop 15m /social-flow:grow-youtube <channel> # while a fresh video is under watch (§2b) ``` **One difference from Threads sets this skill's structure** — a Short is a video. Making one takes research, authoring, images, voice, and a build. So publishing happens **only from the queue**, and what enters the queue is the crux of this loop. There are two ways to fill it. - **A human fills it** — build with `/social-flow:storyboard → produce` and stamp `queue: ready` in storyboard.md. - **The loop fills it** — with plan `autoproduce.enabled: true`, the moment the queue runs dry the tick builds an episode itself and stamps the marker (§2.5). Topics, subject scope, and the per-episode cost cap are all written in the plan, and only episodes that pass the machine gates enter the queue. **Hourly is the resting cadence** — slot publishing and comment replies both live fine at that resolution, and authoring only happens when the queue is empty anyway. **The velocity watch is the one thing that hourly can't hold.** The tick samples a video's view counter only as often as the tick runs, so a watch left o
