## What it does

The skill retrieves a transcript from a YouTube URL or video ID, then formats it as timestamped chapters, a summary, a Twitter/X thread, a blog post, or quotes. You can request timestamps and select a language with fallbacks. If you don’t choose a format, it produces a summary.

It includes the Python script `scripts/fetch_transcript.py`, which accepts standard YouTube links, short links, Shorts, embeds, and live links. Before running it, prepare an isolated Hermes Agent environment, add the `youtube` extra, and use the Python interpreter that successfully imports `youtube_transcript_api`. Without that setup, transcript fetching won’t run. If the result is empty, the skill retries without a language selection; if that also fails, it tells you transcripts are likely disabled.

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NousResearch/hermes-agent --skill youtube-content -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/youtube-content/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/youtube-content/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NousResearch/hermes-agent --skill youtube-content -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/youtube-content/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NousResearch/hermes-agent --skill youtube-content -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/youtube-content/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NousResearch/hermes-agent --path skills/media/youtube-content
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/youtube-content/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NousResearch/hermes-agent --skill youtube-content -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NousResearch/hermes-agent/tree/HEAD/skills/media/youtube-content/SKILL.md

## When to use it
- fetch a transcript from a YouTube link
- split a video into timestamped chapters
- condense a video into a short summary
- reshape video content as a Twitter/X thread
- draft a blog post or collect timestamped quotes

## Example prompts
- Summarize this video: `https://youtube.com/watch?v=VIDEO_ID`.

# YouTube Content Tool

## When to use

Use when the user shares a YouTube URL or video link, asks to summarize a video, requests a transcript, or wants to extract and reformat content from any YouTube video. Transforms transcripts into structured content (chapters, summaries, threads, blog posts).

Extract transcripts from YouTube videos and convert them into useful formats.

## Setup

Use `terminal` with the Python from a PM-prepared Hermes source checkout. The
`youtube` extra declares the helper's dependency; do not install packages into
Hermes with raw pip or project-discovering `uv run`.

From that checkout, first follow the isolated development-home setup in
[Package Management](https://hermes-agent.nousresearch.com/docs/reference/package-management#developer-workflow),
then prepare the extra and reactivate before running the helper:

```bash
source ./activate
python -c "import pm; pm.sync_venv(['youtube'], explicit=True)"
source ./activate
python -c "import youtube_transcript_api; print(youtube_transcript_api.__file__)"
```

On Windows, use `. .\activate.ps1` instead of `source ./activate`. If the terminal
runs on a different host or in a sandbox, use an explicitly isolated helper
environment there, not the agent's production environment. Run every command
below with the interpreter whose import check succeeded.

## Helper Script

`SKILL_DIR` is the directory containing this SKILL.md file. The script accepts any standard YouTube URL format, short links (youtu.be), shorts, embeds, live links, or a raw 11-character video ID.

```bash
# JSON output with metadata
python SKILL_DIR/scripts/fetch_transcript.py "https://youtube.com/watch?v=VIDEO_ID"

# Plain text (good for piping into further processing)
python SKILL_DIR/scripts/fetch_transcript.py "URL" --text-only

# With timestamps
python SKILL_DIR/scripts/fetch_transcript.py "URL" --timestamps

# Specific language with fallback chain
python SKILL_DIR/scripts/fetch_transcript.py "URL" --language tr,en
```

## Output Formats

After fetching the transcript, format it based on what the user asks for:

- **Chapters**: Group by topic shifts, output timestamped chapter list
- **Summary**: Concise 5-10 sentence overview of the entire video
- **Chapter summaries**: Chapters with a short paragraph summary for each
- **Thread**: Twitter/X thread format — numbered posts, each under 280 chars
- **Blog post**: Full article with title, sections, and key takeaways
- **Quotes**: Notable quotes with timestamps

### Example — Chapters Output
