What it does
Lecture To Notes is an agent skill from ysyecust/lecture-to-notes. Use when users provide YouTube, Bilibili, or X/Twitter lecture URLs and want reader-first Chinese LaTeX/PDF notes with source-faithful claims, fluent authored prose, and verified teaching figures, especially requests phrased as lecture notes, 视频转PDF, 课程笔记, 讲义, YouTube笔记, B站笔记, X/Twitter lecture notes, or BV号; do not produce transcript dumps, quota-padded prose, or screenshot galleries.
Its SKILL.md is about 14k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `agents/openai.yaml` and `references/reader-first-writing.md`).
It sits in Documents & Office, covering LaTeX, Transcription and PDF. It works with LaTeX, YouTube, X (Twitter) and Bilibili. The repository describes itself as: Turn YouTube/Bilibili lectures into smart-cropped LaTeX/PDF notes. Claude Code & Codex skill.
When your agent uses it

Example prompts
- “/lecture-to-notes”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.

What it can do on your machine
Read from SKILL.md and the folder at commit 0ef4e6f. 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
Shell commands in SKILL.md call:
python3yt-dlppipbashffmpegmagickbrewpipxwhisperpdftotext
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:
bilibili.comtug.org
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
Lecture To Notes loads about 14k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 101 tokens; SKILL.md has 5,939 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.
- NoteRuns commands with sudoSKILL.md:56
echo " Linux: sudo apt install texlive-full"
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 5,939 words (~14,078 tokens).
“Turn a YouTube, Bilibili, or X/Twitter lecture video into a complete, compilable .tex note set and a rendered PDF.”
