11 free Claude skills for your YouTube channel: how to install YouTube Agent Skill (step by step)

YouTube Agent Skill is a free, open-source (MIT license) package of 11 Claude skills written for YouTube channels. A skill is a ready-made instruction package that has Claude do a specific job using a specific method; it's invoked with a command like /yt-script. It requires no sign-up, API key or channel connection. It never publishes anything on your behalf: it writes and checks; you do the uploading.

The smoothest route is Claude Code (Claude running on your computer; it requires a paid Claude subscription or a Console account). If it isn't installed, paste irm https://claude.ai/install.ps1 | iex into PowerShell on Windows or curl -fsSL https://claude.ai/install.sh | bash into Terminal on Mac, then type claude in the terminal and sign in with your Claude account. Details are on the official installation page. The package's six Python tools (hook score, title check, cut list, etc.) only work fully in an environment that can run files, such as Claude Code.

Open Claude Code; you'll see an empty chat. Copy the two lines below exactly as they are, paste them and send. Claude downloads the repository and installs the skills; if it asks for permission, read the request and approve it. The message being in English is no problem; if you ask in Turkish, the answers come in Turkish.

If you want to install it yourself, run these two commands in the terminal (Git must be installed). The skills are copied to the ~/.claude/skills/ folder and show up in all your projects. If you only want to use them in one project, copy the same folders into that project's .claude/skills/ folder. If you'd rather install it as a plugin, type /plugin marketplace add Jakeschincariol/youtube-agent-skill in Claude Code, followed by /plugin install youtube-agent.

Close and reopen Claude Code and type /: if commands like /yt-script and /yt-package appear in the list, the installation is complete. To test it, type /yt-script and describe a video idea in a single sentence (e.g. "A video showing café owners how to shoot menu photos in 3 minutes"). You can also send the command empty; Claude will ask you for the missing information.

Every skill in the package reads the voice.md file that describes how you talk; this file shapes the result more than anything else. The file lives at ~/.claude/youtube/voice.md. The easiest way: send Claude the scripts of your 3 best videos (the subtitles/transcript in YouTube Studio) and say "write my voice.md from these". The template has these headings: who you're talking to, how you talk, words you never use, phrases you use often, things you won't claim, and your video format.

The six commands featured in the video are in the first six lines; the other five come with the same package:

• /yt-script: from idea to script; 5 hooks from 21 hook formulas, scores, then the voiceover script.
• /yt-package: checks the title and thumbnail text as a single package (truncation, repetition, vagueness).
• /yt-edit: a cut list with timestamps from the transcript; dead air, filler words, retakes.
• /yt-comment: sorts comments into 4 piles, writes replies in your tone and tells you which one to pin.
• /yt-plan: a week based on the hours you can spare; 1 main video, 1 light video, 3 Shorts.
• /yt-viral: ranks the videos in your niche that most outperform their own channel's average and names the pattern.
• /yt-retention: reads an audience retention export; drop-off at the hook, falling points, what should change.
• /yt-shorts: finds Shorts candidates inside a long video and writes a new first line for each.
• /yt-seo: a description, tags that actually help and the 3 searches the video should win.
• /yt-chapters: chapter titles from the transcript that follow YouTube's rules.
• /yt-audit: reviews the whole channel and ends with a single fix instead of 20 suggestions.

• Monday: plan your week with /yt-plan (say how many hours a week you can spare).
• Main video: prepare the script with /yt-script, and the title and thumbnail text with /yt-package.
• After filming: give it the subtitle file (.srt) and let /yt-edit produce the cut list.
• After publishing: copy the comments and give them to /yt-comment; read the replies and send them yourself.
• Weekend: look at the standout videos in your niche with /yt-viral and pick next week's idea from there.

• It doesn't publish or connect to your channel: every skill ends with text for you to copy and the question "publish, or change?".
• The hook score is an estimation tool: a low score means "take another look"; a high score doesn't guarantee views.
• /yt-viral doesn't sign in: it only reads public lists and never accesses your account. A comparison needs at least 4 videos per channel.
• It doesn't make up numbers: it asks you for any figure it doesn't know, or writes that line without a number.
• The package is written in English; it produces Turkish output when you ask for Turkish, but some of the hook formulas may not have the same effect in Turkish; read them out loud and decide.
