flow-media

Generate images (Nano Banana Pro / Imagen) and videos (Veo 3.1) through Google Flow using the account's Ultra/Pro SUBSCRIPTION credits instead of the metered Gemini/Vertex API — no per-call API cost. Use when the user wants to create a thumbnail, cover, poster, b-roll clip, image, or short video with AI and wants to avoid API billing, or explicitly mentions Flow / gflow / Veo / Nano Banana via subscription. Wraps the gflow-cli tool; encodes this machine's Flow new-UI quirk (PREFER_CLASSIC) and credit-safe retry rules learned the hard way. NOT for the paid Gemini-API nano-banana-pro path (that costs money) — this is the subscription path.

loop-or-not

Decide whether a task in the current project is worth running as an agent loop. Analyzes the repo for evidence first (tests/CI/bench scripts = available verifiers; issue+PR queues = recurring work; module boundaries), then interviews the user one question at a time on the genuine decisions, and returns one of three verdicts — don't loop (stay in the loop yourself), timer loop (/loop, /schedule), or goal loop (/goal) — with cited evidence and, when looping is warranted, a drafted four-part contract (goal / verification / boundary / stop) bound to real commands found in the repo. Recommending NO loop is a first-class outcome. Use when the user asks 值不值得 loop / should I loop this / 要不要上 /goal / 这个活能不能挂个循环自动跑, or wants to apply loop engineering to a project.

backlog-manager

GitHub backlog governance manager-loop. Triage open issues (type + routing labels), complete thin descriptions, maintain a bounded ready queue (Todo ≤ 5) on a GitHub Projects board, and repair board drift (closed issue still "In Progress" etc.). Config-driven — reads .claude/backlog-manager.yaml from the target repo; runs an init flow to generate it if missing. DRY-RUN by default, pass "apply" to execute writes. Use for recurring backlog grooming / issue triage of any GitHub repo, standalone or driven by /loop. Requires gh CLI with repo + project scopes.

Common Issues

Q: Age-restricted videos? A: Use --cookies with exported browser cookies: --cookies cookies.txt

Q: Format not available? A: Some videos may not have all quality options. Script will auto-select best available.

Q: Download speed slow? A: This is usually server-side throttling. Consider using a VPN or waiting.

Q: Need to login for private videos? A: Export cookies from your browser after logging in, then use --cookies.

Q: Audio extraction fails? A: Install ffmpeg: brew install ffmpeg (macOS) or apt install ffmpeg (Linux)

Example Conversations

User: "帮我下载这个 YouTube 视频: https://www.youtube.com/watch?v=dQw4w9WgXcQ"

Claude:

# Install yt-dlp
pip install yt-dlp --break-system-packages

# Download video
python /mnt/skills/user/youtube-downloader/scripts/download_video.py \
  "https://www.youtube.com/watch?v=dQw4w9WgXcQ" \
  -o /mnt/user-data/outputs

# Present files
present_files([...])

User: "下载这个 YouTube 视频的音频，我只要 MP3"

Claude:

python /mnt/skills/user/youtube-downloader/scripts/download_video.py \
  "VIDEO_URL" \
  --audio-only \
  -o /mnt/user-data/outputs

User: "Download this playlist, but only the first 5 videos"

Claude:

python /mnt/skills/user/youtube-downloader/scripts/download_video.py \
  "PLAYLIST_URL" \
  --playlist -n 5 \
  -o /mnt/user-data/outputs

How It Works

Workflow

URL Parsing: Detect platform and content type (video/playlist)
Format Selection: Determine best available format based on user preference
Download: Stream video/audio with progress display
Post-Processing: Extract audio (if requested), embed subtitles
Metadata: Save video information to JSON

Under the Hood

This skill wraps yt-dlp with sensible defaults:

Automatic format selection for best quality
Proper filename sanitization
Retry logic for failed downloads
Progress display with ETA

Limitations

Some sites may require authentication (cookies)
Age-restricted content needs browser cookies
Download speed depends on source server
Some DRM-protected content cannot be downloaded
Live streams can only be downloaded after they end (VOD)
