What it does
Get Youtube Transcript is an agent skill from Abilityai/cornelius. Extract the transcript from a YouTube video by URL or video ID. Use when the user shares a YouTube link and wants the transcript, captions, or text content of the video. Falls back automatically if the requested language isn't available.
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering Video and podcast notes. It works with YouTube. The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.
When your agent uses it
- The user shares a YouTube link and wants the transcript
- Text content of the video
Example prompts
- “/get-youtube-transcript”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash
Workflow steps
3 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 fd5e9a4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
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:
youtu.be
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
Get Youtube Transcript loads about 525 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 201 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.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash
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.

Get YouTube Transcript
Extract a full transcript from any YouTube video using the local youtube-transcript-api (no rate limits, no API key required).
State Dependencies
| Source | Location | Read | Write |
|---|---|---|---|
| Script | scripts/utilities/yt-transcript.sh | ✓ | - |
| Venv | scripts/utilities/yt_transcript_venv/ | ✓ | - |
| YouTube | External (via youtube-transcript-api) | ✓ | - |
Process
Step 1: Extract the transcript
Run the wrapper script with the URL or video ID the user provided:
$PROJECT_ROOT/scripts/utilities/yt-transcript.sh "<url-or-id>"Options:
-l <lang>— language code (default:en). If user specifies a language, pass it.-f text— plain text output (default, best for reading)-f json— structured output with timestamps (use when user needs timestamps)
Step 2: Handle errors
If the script fails:
- Language not found — retry without
-lflag (auto-selects any available language) - Video unavailable — inform user the video may be private, deleted, or region-restricted
- No transcript available — inform user the video has no captions
Step 3: Present the transcript
Return the full transcript text to the user. If it's long (>500 lines), summarize what the video covers first, then provide the full text.
Example
User: "get me the transcript of https://youtu.be/abc123"
$PROJECT_ROOT/scripts/utilities/yt-transcript.sh "https://youtu.be/abc123"Notes
- Uses
youtube-transcript-apiPython package — works locally with no quota - Falls back to any available language if English isn't found
- The MCP youtube-transcript tool hits rate limits; always prefer this script
