Subtitle Timing
Align subtitles to speech without drifting.
Use it for
Captioned video where a transcript exists but no timecodes
Skip it if
Translation quality — timing and wording are separate passes
What it is
Takes a transcript and produces cue-level timecodes: short lines, under two seconds where possible, no more than two lines on screen. The check is mechanical — every cue starts before its audio and ends after it — which is what separates a usable skill from a guess with timestamps.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.
Terminal
npx skills add subtitle-timingHow to judge it
Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
