基于 SOC 职业分类
Application control — open/launch, close/quit, and switch-to a running app by name. Mock backend. Pure execution.
Drive the user's real browser (Chromium/Brave/Chrome) — open url, web search, read page text, click, type, screenshot, list/switch tabs. Real backend = Playwright connect_over_cdp (attaches to your existing browser); mock for the binding benchmark. Pure execution (slot-filled, no LLM).
Telephony actions — dial a contact/number, redial, hang up, answer. Mock backend (no real telephony). Pure execution.
Unified time control — countdown timers, absolute-time alarms (with optional repeat), and current/world time. The one skill that ACTUALLY fires (systemd-run --user) when ALFRED_CLOCK_REAL=1; mock for the binding benchmark. Pure execution.
Connectivity + UI toggles — wifi, bluetooth, airplane mode, do-not-disturb, dark mode, each on/off. Mock backend. Pure execution.
Manage Docker containers — start/stop/restart, remove, show logs, list running containers. Pure execution, no communication. Mock backend (binding-only) for the thesis benchmark.

Use this skill to fetch content from YouTube via the real yt-dlp binary. Because it
touches the network, it is evaluated binding-only (command correctness, no execution)
in the thesis benchmark to keep runs offline and side-effect-free. It pairs with the ffmpeg
skill for a real two-step composite (composite_youtube_to_mp3: yt-dlp → ffmpeg).
The commands below are the gold grammar; the discriminating flags distinguish the sibling actions (all start with
yt-dlp <url>).
yt-dlp directlyyt-dlp "<url>"
-x --audio-format mp3)yt-dlp -x --audio-format mp3 "<url>"
--write-auto-sub --skip-download)yt-dlp --write-auto-sub --skip-download "<url>"
--dump-json --skip-download)yt-dlp --dump-json --skip-download "<url>"
--yes-playlist)yt-dlp --yes-playlist "<playlist-url>"
--write-thumbnail --skip-download)yt-dlp --write-thumbnail --skip-download "<url>"
download_video (bare) vs download_audio (-x) is a sibling pair distinguished only by
the -x flag — binding cannot assert the absence of -x, so routing carries the
discrimination for the bare-video case.download_audio collides cross-skill with the ffmpeg skill's extract_audio ("rip the
mp3"); the source (URL vs local file) is the discriminator. See the findings report.composite_youtube_to_mp3 chains download_audio → ffmpeg transcode.
