Audit and rewrite a YouTube channel end-to-end for 2026: name and @handle, banner (2560x1440 with the 1235x338 mobile/TV safe area), profile picture, About plus searchable keywords, trailer for non-subscribers vs featured video for subscribers, sections and playlist layout, watermark, links. Triggers on "optimize my YouTube channel", "rewrite my channel about", "fix my banner", "channel audit", "set my trailer". Converts a viewer into a subscriber. Not for writing a video title…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# YouTube Channel Optimizer Audit the parts of a YouTube channel page against what actually converts a one-time video-viewer into a subscriber in 2026, then rewrite each part that needs it. A viewer clicks through from one video to the channel page in a moment of interest. That moment decides whether they subscribe or leave.

How to install
mdr add sergebulaev/youtube-skills/yt-channel-optimizer@sha256:f2dff5634e24efa5The line at the top of this page pins the label git:20260909.9ed0a30, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
