Quick Start

Basic Download (Best Quality)

yt-dlp -P "~/Downloads/yt-dlp" "VIDEO_URL"

YouTube Download (Recommended - with cookies)

YouTube often blocks direct downloads with 403 errors. Always use browser cookies for YouTube:

yt-dlp -P "~/Downloads/yt-dlp" --cookies-from-browser chrome "YOUTUBE_URL"

Supported browsers: chrome, firefox, safari, edge, brave, opera

Download with Custom Output Path

yt-dlp -P "/path/to/save" -o "%(title)s.%(ext)s" "VIDEO_URL"

Common Tasks

1. Download Video (Default - Best Quality)

yt-dlp -P "~/Downloads/yt-dlp" "VIDEO_URL"

2. Extract Audio Only (MP3)

yt-dlp -P "~/Downloads/yt-dlp" -x --audio-format mp3 "VIDEO_URL"

3. Download with Subtitles

yt-dlp -P "~/Downloads/yt-dlp" --write-subs --sub-langs all "VIDEO_URL"

4. Download Specific Quality

yt-dlp -P "~/Downloads/yt-dlp" -f "bestvideo[height<=720]+bestaudio/best[height<=720]" "VIDEO_URL"

1080p:

yt-dlp -P "~/Downloads/yt-dlp" -f "bestvideo[height<=1080]+bestaudio/best[height<=1080]" "VIDEO_URL"

yt-dlp -F "VIDEO_URL"

Then download specific format by ID:

yt-dlp -P "~/Downloads/yt-dlp" -f FORMAT_ID "VIDEO_URL"

# Download entire playlist
yt-dlp -P "~/Downloads/yt-dlp" -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" "PLAYLIST_URL"

yt-dlp -P "~/Downloads/yt-dlp" -I 1:5 "PLAYLIST_URL"

7. Download with Thumbnail

yt-dlp -P "~/Downloads/yt-dlp" --write-thumbnail "VIDEO_URL"

Workflow

When user provides a video URL:

  1. Identify the platform:
  • YouTube/YouTube Music → Always use `--cookies-from-browser chrome`
  • Other sites → Try without cookies first
  1. Ask what they want (if not specified):
  • Just download the video?
  • Extract audio only?
  • Need subtitles?
  • Specific quality?
  1. Construct the command based on requirements
  1. Execute the download using Shell tool with required_permissions: ["all", "network"]
  1. Handle errors:
  • 403 Forbidden → Retry with --cookies-from-browser
  • Connection issues → yt-dlp auto-resumes, just retry
  • Format unavailable → Use -F to list formats, then select
  1. Report the result - file location and any errors
