What it does
Youtube Source is an agent skill from ad-repo/nullplayer. YouTube channel uploads in the Radio tab — browse channels, download a video's audio (FLAC, ALAC, MP3, AAC, or the original stream) and/or its video (360p–4K) ad-free, store in a user folder, and play/cast locally. Use when working on YouTube source UI, channel/video listing, the video row menu, downloads, manifest tracking, or format settings.
Its SKILL.md is about 7.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with YouTube. The repository describes itself as: nullPlayer is a free open source macOS media player with some unique features.
When your agent uses it
- Working on YouTube source UI
- Channel/video listing
- The video row menu
- Manifest tracking
Example prompts
- “/youtube-source”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Radio tab → + Add YouTube Channel
- Paste a YouTube channel URL (e.g., https://www.youtube.com/@channel_name) — or find one by
- Channel appears as a folder; expand to see uploads
- Right-click a video → Audio ▸ or Video ▸ → Play, Play and Replace Queue, Play Next or
- Library → YouTube → Set Download Folder… to choose where downloads live
- Library → YouTube → Audio Format and Video Quality to pick what those downloads are
- Library → YouTube → Videos per Channel to pick how many recent uploads to list (50 / 100 / 200 / 500)
What it can do on your machine
Read from SKILL.md and the folder at commit 3d87ce1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
yt-dlp
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:
youtube.com
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
Youtube Source loads about 7.8k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 3,396 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 passed
The automated check found no risky patterns in SKILL.md.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,396 words (~7,792 tokens).
“Subscribe to YouTube channels in the Radio tab and browse their uploads. A video row's menu offers Audio ▸ and Video ▸, each with the library's track verbs; the chosen form is downloaded (ad-free, via yt-dlp) when it isn't on…”
