media-transcript

Pull a video's transcript (captions/subtitles) as clean text — the doc-ingest sibling for video. Any task that references a YouTube (or other yt-dlp-supported) URL can consume the spoken content as text instead of being blind to it.

Usage:

python3 skills/media-transcript/scripts/transcript.py <url> [--lang en] [--timestamps] [--json]

Prints the transcript to stdout. --timestamps prefixes blocks with [mm:ss] cue starts (use when the question asks when/after what something was said). --json wraps the result as {"url", "ok", "kind", "text"|"error"} for programmatic callers.

When to use

  • A task references a video URL whose content matters ("what did they say about X", "what number is mentioned after Y", summarizing a talk).
  • The agent-eval harness hits video-based benchmark tasks (4 of 10 GAIA L3 fails on 2026-07-30 were video-content questions this skill unblocks).
  • Anything needing spoken-word content where captions exist.

Not for:

  • Local audio/video files — use skills/audio-transcribe (whisper on the audio track); the script points there and exits 3.
  • Videos with no captions at all — v1 is captions-only (uploader subs preferred, auto-captions fallback). The script says so honestly (exit 1) rather than guessing; a whisper-on-downloaded-audio fallback is a possible v2, deliberately out of scope (media downloads are heavyweight and often unnecessary).

Behavior

  • Prefers uploader subtitles over auto-generated captions; --lang preference (default en) with graceful fallback to available English variants.
  • Downloads ONLY the subtitle track — never the media stream — into a private temp dir, removed afterwards. No API keys.
  • Auto-caption VTTs repeat rolling caption windows; the parser dedupes them, strips inline tags/entities, and drops cue numbers, producing readable prose.
  • yt-dlp is probed at runtime (PATH binary, else the importable module) — a host without it gets one actionable error naming the install, never a crash (same design language as doc-ingest's extractor probing).

Exit codes: 0 transcript printed · 1 failure (no captions / tool error) · 2 bad invocation · 3 handled-elsewhere pointer (local media file).
