What it does
Subtitle Caption is an agent skill from mohitagw15856/pm-claude-skills. Write or translate subtitles/captions that respect reading speed and timing rules. Use when asked to write subtitles, captions, SRT/VTT content, or to translate subtitles for a video. Produces properly-formatted, readable subtitles — line-length and reading-speed compliant, well-segmented, with translation that fits the time available, plus SDH/caption guidance where relevant.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Transcription and Translation. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Subtitle Caption loads about 864 tokens when it runs. Until then it costs about 99 tokens; SKILL.md has 415 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- subtitle-caption
- description
- Write or translate subtitles/captions that respect reading speed and timing rules. Use when asked to write subtitles, captions, SRT/VTT content, or to translate subtitles for a video. Produces properly-formatted, readable subtitles — line-length and reading-speed compliant, well-segmented, with translation that fits the time available, plus SDH/caption guidance where relevant.
Subtitle & Caption Skill
Subtitles fail when they're too long to read before they vanish, badly segmented, or a literal translation that overruns the timing. Good subtitling obeys real constraints: reading speed (≈17 chars/sec / ~160–180 wpm), line length (~42 chars), max 2 lines, and sentence-aware segmentation. This skill writes or translates captions to those rules — readable, well-timed, and condensed to fit.
Required Inputs
Ask for these only if they aren't already provided:
- The content — a transcript, script, or existing subtitles (with timecodes if you have them).
- Task — caption (same language), translate-subtitle (to another language), or SDH (deaf/HOH captions with sound cues).
- Format — SRT, WebVTT, or plain; and any platform limits (YouTube, broadcast, Netflix-style specs).
- Constraints — reading-speed/line-length target if non-standard.
Output Format
Subtitles: [content] — [task]
The subtitles in the requested format (SRT/VTT), each cue:
- ≤2 lines, each ~42 chars, broken at natural phrase boundaries (don't split an article from its noun).
- Timed to reading speed — long sentences are condensed (not every word — paraphrase to the gist) so they're readable in the time available. Where you have timecodes, respect them; where not, note suggested durations.
- For translation: render meaning compactly — the target must fit the same time slot, so condense more aggressively than prose translation, keeping the essential meaning.
- For SDH: include speaker IDs and
[sound cues](e.g.[door slams],[tense music]).
Notes — where you condensed/cut and why, any cue that's tight on reading speed (a 🔴 flag to adjust timing), and segmentation choices.
Show full SKILL.md (175 more words)Show less
Quality Checks
- Each cue is ≤2 lines and within the line-length limit (~42 chars)
- Cues are readable at standard reading speed — long lines are condensed, not crammed
- Line breaks fall at natural phrase boundaries (no orphaned articles/prepositions)
- Translations are condensed to fit the original timing, keeping the meaning
- SDH captions include speaker IDs and sound cues where requested
- Output is in the requested format (valid SRT/VTT structure)
Anti-Patterns
- Do not exceed reading speed — a perfectly accurate caption no one can read in time has failed
- Do not translate verbatim for subtitles — the target overruns the slot; condense to the gist
- Do not break lines mid-phrase — split at clause/phrase boundaries for readability
- Do not exceed 2 lines per cue — split into multiple cues instead
- Do not omit sound cues in SDH — they're the point of accessible captions
Based On
Subtitling standards — reading-speed (CPS) limits, ~42-char lines, 2-line max, phrase-boundary segmentation, SDH conventions.
Example Trigger Phrases
- "Write subtitles for this video."
- "Make captions as an SRT file."
- "Translate these subtitles."
- "Fix the reading speed of these captions."
