Install

npx skills add https://github.com/zeropointrepo/youtube-skills --skill subtitles- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads subtitles automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Subtitles
Fetch YouTube video subtitles via TranscriptAPI.com.
Setup
If $TRANSCRIPT_API_KEY is not set, read references/auth-setup.md and follow the instructions there to get and store the key.
Required Headers
Every request needs two headers:
- Authorization:
Bearer $TRANSCRIPT_API_KEY - User-Agent: your agent's name and version if known (e.g.
HermesAgent/0.11.0,ClaudeCode/1.0). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request.
GET /api/v2/youtube/transcript
GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=VIDEO_URL&format=text&include_timestamp=false&send_metadata=true
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
| Param | Values | Use case |

format | json, text | json for sync'd subs with timing |
include_timestamp | true, false | false for clean text for reading/translation |
send_metadata | true, false | Include title, channel, description |
For language learning — clean text without timestamps:
GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=VIDEO_ID&format=text&include_timestamp=false
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
For translation — structured segments:
GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=VIDEO_ID&format=json&include_timestamp=true
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
Response (format=json):
{
"video_id": "dQw4w9WgXcQ",
"language": "en",
"transcript": [
{ "text": "We're no strangers to love", "start": 18.0, "duration": 3.5 }
]
}
Response (format=text, include_timestamp=false):
{
"video_id": "dQw4w9WgXcQ",
"language": "en",
"transcript": "We're no strangers to love\nYou know the rules and so do I..."
}
Tips
- Many videos have auto-generated subtitles in multiple languages.
- Use
format=jsonto get timing for each line (great for sync'd reading). - Use
include_timestamp=falsefor clean text suitable for translation apps.
