What it does
Yt Chapters is an agent skill from Jakeschincariol/youtube-agent-skill. Write YouTube chapters from a transcript, validated against YouTube's own rules so they actually render. Use for "add chapters", "timestamps", "break this video into sections".
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `chapters.py`).
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
- Break this video into sections
Example prompts
- “s own rules so they actually render. Use for”
- “timestamps”
- “break this video into sections”
- “/yt-chapters”
Requirements
- Python 3
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 Chapters loads about 345 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 190 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-chapters
- description
- Write YouTube chapters from a transcript, validated against YouTube's own rules so they actually render. Use for "add chapters", "timestamps", "break this video into sections".
yt-chapters
python3 chapters.py transcript.srt --target 8The rules, which are not optional
A chapter list that breaks any of these silently does not become chapters at all - the block just sits in the description doing nothing:
- The first entry must be 00:00.
- There must be at least three.
- Each must be at least 10 seconds long.
The tool checks all three and tells you when a list is invalid rather than letting you paste it.
Retitle every line
chapters.py finds the BOUNDARIES well - it scores the pauses you actually took by how much the
vocabulary shifts across them. The titles it emits are the topic words, and they are a draft. A
chapter called "Thumbnails Titles Packaging" is a placeholder. Rewrite each one as the promise of
that section, in the user's voice, three to five words.
Chapters are also a retention diagnostic: if a section cannot be named in five words, it is two sections or it is filler.
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?
