Individual skill
caption-qa
Check SRT or WebVTT captions and subtitles against published standards (Netflix English, BBC subtitle guidelines, DCMP Captioning Key) for reading speed, line length, line count, time on screen, gaps and overlaps, then fix failures by retiming before rewording. Use when asked to QA, lint or validate captions, check whether subtitles read too fast, prepare captions for Netflix, broadcast or educational delivery, or add a caption check to CI.

# Caption QA
Captions fail delivery and accessibility review on numbers: characters a second, characters a line, time on screen and the gap between captions. Each standard publishes its own limits, and they differ, so "are these captions OK?" has no answer until you know where they are going. This skill picks the right set of limits, measures every cue the same way the published limits are written, and fixes failures without cutting the speaker's words.
## When to Use This Skill
- The user has an `.srt` or `.vtt` file and asks whether it is ready to ship, or why a platform rejected it.
- The user asks whether captions or subtitles read too fast, or have lines that are too long.
- Captions are headed for Netflix, a broadcaster, or US educational media, and must meet that spec.
- The user wants caption checks in CI so a bad file fails the build.
## Pick the Standard
If the user names no target, use Netflix English (adult) and say that you did.
