Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 18 other files (for example `.github/workflows/newsletter.yml`, `README.md` and `dashboard.py`).
It sits in Documents & Office. It works with YouTube and Python. The repository describes itself as: Claude skill for turning YouTube transcripts from your favorite channels into EPUB ebooks, delivered to your email inbox regularly.
When your agent uses it
- Documents & Office work in your project
Example prompts
- “/youtube-to-ebook”
Requirements
- Python 3
- A Bash shell
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- YouTube Shorts Detection
- Videos Not in Chronological Order

- Transcript Accuracy (Names, Terms)
- Cloud Automation Blocked
What it can do on your machine
Read from SKILL.md and the folder at commit 7f67fd6. 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 and Shell), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
youtube.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
GMAIL_APP_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Youtube To Ebook loads about 1.2k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 325 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:51
└── .env # API keys - NoteMentions a .env fileSKILL.md:150
Add Gmail credentials to `.env` to receive ebooks via email:
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 325 words (~1,197 tokens).
“Transform YouTube videos from your favorite channels into well-written magazine-style articles, delivered as an EPUB ebook.”
