Baixa vídeos (sempre em MP4) ou apenas o áudio (sempre em MP3) do YouTube e de centenas de outros sites (Vimeo, Twitter/X, Instagram, TikTok etc.) usando yt-dlp, instalando e configurando o yt-dlp/ffmpeg/Deno automaticamente se não estiverem presentes. Use esta skill SEMPRE que o usuário pedir para baixar um vídeo, baixar uma música/áudio de um vídeo, extrair MP3 de um link, baixar uma playlist, salvar um vídeo do YouTube, ou colar uma URL de vídeo pedindo download — mesmo que ele não mencione "yt-dlp". Também use quando o download falhar por yt-dlp desatualizado ou ausente.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. 0 are common, 0 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 28 edited versions we read keep these.
0
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.

No Windows, o winget instala o deno.exe FORA do PATH — localize-o em %LOCALAPPDATA%\Microsoft\WinGet\Packages\DenoLand.Deno_*\deno.exe
“Common” is measured: kept by at least 6 in 10 of the 28 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

YouTube — Download de vídeos e áudios (yt-dlp)
Skill para baixar vídeos em MP4 e áudios em MP3 com yt-dlp, cuidando da instalação e configuração do ambiente quando necessário.
Passo 1 — Verificar o ambiente (sempre, antes de baixar)
Windows (PowerShell):
Get-Command yt-dlp -ErrorAction SilentlyContinue
Get-Command ffmpeg -ErrorAction SilentlyContinuemacOS/Linux: which yt-dlp ffmpeg
Se o yt-dlp NÃO estiver instalado
pip install -U yt-dlpSe o pip falhar com erro de SSL/certificado, a causa provável é antivírus ou
proxy corporativo interceptando HTTPS (Avast, por exemplo, faz isso). Correção
no Windows: pip install pip-system-certs e repetir.
Se o ffmpeg NÃO estiver instalado
O ffmpeg é obrigatório (converte MP3 e junta vídeo+áudio):
# Windows — use --source winget: a fonte msstore falha com antivírus que interceptam HTTPS
winget install --id Gyan.FFmpeg -e --source winget --accept-source-agreements --accept-package-agreementsmacOS: brew install ffmpeg · Linux: sudo apt install ffmpeg
Runtime JavaScript (exigido pelo YouTube desde 2026)
Se o yt-dlp emitir o aviso "No supported JavaScript runtime could be found", o YouTube pode ocultar os melhores formatos. Correção:
- Instalar Deno se não existir:
winget install --id DenoLand.Deno -e --source winget(macOS:brew install deno) - No Windows, o winget instala o deno.exe FORA do PATH — localize-o em
%LOCALAPPDATA%\Microsoft\WinGet\Packages\DenoLand.Deno_*\deno.exe - Registre no config global do yt-dlp (
%APPDATA%\yt-dlp\config), uma linha:--js-runtimes "deno:<caminho completo do deno.exe>"
Se o download falhar com erro de "signature", "extractor" ou HTTP 403
Quase sempre é yt-dlp desatualizado (o YouTube muda com frequência):
pip install -U yt-dlp e tente de novo.
Passo 2 — Baixar
Pergunte (ou deduza do pedido) apenas o que faltar: URL, vídeo ou só áudio, e pasta de destino. Sem pasta indicada, use a pasta de Downloads do usuário.
Vídeo — sempre MP4
Prefere H.264+AAC (compatibilidade máxima); se o site entregar outro codec, remuxa o container para MP4:
yt-dlp -f "bv*[vcodec^=avc1]+ba[acodec^=mp4a]/bv*+ba/b" --merge-output-format mp4 --remux-video mp4 --no-playlist -o "<PASTA>\%(title)s.%(ext)s" "<URL>"Áudio — sempre MP3 (melhor qualidade)
yt-dlp -x --audio-format mp3 --audio-quality 0 --no-playlist -o "<PASTA>\%(title)s.%(ext)s" "<URL>"Playlist inteira
Remova --no-playlist e use o modelo de saída com subpasta numerada:
-o "<PASTA>\%(playlist_title)s\%(playlist_index)s - %(title)s.%(ext)s"Atenção: URLs de vídeo dentro de playlist (watch?v=...&list=...) baixam a
playlist INTEIRA sem --no-playlist. Só omita a flag se o usuário pediu a
playlist explicitamente.
Observações
- Em PowerShell os modelos
%(title)sfuncionam entre aspas duplas normalmente; em arquivos .bat é preciso dobrar o % (%%(title)s). - Para ver qualidades disponíveis antes de baixar:
yt-dlp -F --no-playlist "<URL>". - Para validar sem baixar (teste):
yt-dlp --simulate --print "%(title)s" "<URL>". - Este repositório também traz uma interface web local (
apps/baixador/ABRIR.bat) para quem prefere clicar em vez de conversar — indique-a se o usuário pedir "um programa" de download.
Passo 3 — Confirmar
Após o download, liste o(s) arquivo(s) gerado(s) com nome, extensão e tamanho,
confirmando que vídeo saiu .mp4 e áudio saiu .mp3. Lembre o usuário de baixar
apenas conteúdo que tem direito de usar.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
