What it does
Yt Script is an agent skill from Jakeschincariol/youtube-agent-skill. Write a YouTube video script from a raw idea - hook options off 21 formulas, scored, then the full spoken script with the retention beats marked. Use whenever the user wants a video script, a hook, an opening line, "what should I say", "write my next video", or is about to record and does not have the first fifteen seconds yet.
Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `hooks.json` and `hookscore.py`).
It sits in Media & Creative, covering Video scripts and shorts. It works with YouTube. The repository describes itself as: Eleven Claude skills that run a YouTube channel: scripts off 21 hook formulas with a scored hook, title and thumbnail linted as one pairing, an edit decision list from your… The licence is MIT.
When your agent uses it
- The user wants a video script
- An opening line
- What should I say
- Write my next video
Example prompts
- “what should I say”
- “write my next video”
- “/yt-script”
Requirements
- Python 3
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Read ~/.claude/youtube/voice.md if it exists. That is the user's voice profile: how they talk
- Never invent a number, a result or a source. If a figure would strengthen it and you do not have
What it can do on your machine
Read from SKILL.md and the folder at commit a2feb21. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Yt Script loads about 672 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 384 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

yt-script
One idea into a script somebody finishes.
Two tools live in this folder and both actually run. Use them. Do not eyeball the hook.
python3 hookscore.py hooks.txt # rank your hook options
python3 hookscore.py --hook "one line" # score a single oneBefore you write
- Read
~/.claude/youtube/voice.mdif it exists. That is the user's voice profile: how they talk on camera, the words they never use, who they are talking to, what they will not claim. If it does not exist, ask for three of their own videos, read or transcribe them, infer the voice, and write the file. A script in the wrong voice is worse than no script, because they have to read it out loud. - Never invent a number, a result or a source. If a figure would strengthen it and you do not have one, ask for it or write the line without it.
The shape
The first 15 seconds is the whole job. It does three things or the video leaks: confirm the click the title promised, open a question the viewer cannot close, and prove the payoff exists.
- Hook. Write FIVE against the 21 formulas, run them through
hookscore.py, keep the top two, and show the user both with their scores. Never hand over one hook. - The turn (0:15-0:45). Say what the video is going to do, in one sentence, and start doing it. No channel intro, no "before we get started", no subscribe pitch. Those are the single most common cause of the 0:30 cliff.
- The body. One idea per beat. Mark each beat with what is ON SCREEN, not just what is said - a talking head with nothing to look at is a podcast.
- The payoff. Deliver the thing the hook promised, explicitly, and say that you are delivering it: "that is the prompt, it is in the description".
- The close. One ask. Not three.
Show full SKILL.md (81 more words)Show less
What to hand back
- the two best hooks with their scored panels
- the script, beat by beat, with
[ON SCREEN: ...]on every beat - the runtime estimate at 150 words per minute
- one line naming which formula the winning hook used and why it fits this idea
The gate
Nothing here publishes. This skill writes and you publish. Every output ends in a block the user copies, and the last line of every run is the question: ship it, or change it?
